Roof sandwich panels: Standard and customized sizes. Dimensions of sandwich panels Length of roof sandwich panels

Roofing sandwich panels are actively used in the construction of the roof. They have all the basic requirements that apply to materials for construction.

Peculiarities

Sandwich panels are in great demand in construction. They are a material that is characterized by improved performance. Prefabricated panels are adapted to negative climatic factors, therefore they have become in demand in many regions on the territory of Russia. According to monitoring, 86% of roofs are equipped with this material.

Roofing sandwich panels are manufactured for covering roofs for various purposes. The name of the product comes from the English word "sandwich", which translates as "multi-layer sandwich". The roof received this name due to the multilayer structure of its structure.

Products consist of several layers.

Two steel sheets equipped with stiffening ribs. They are treated with anti-corrosion materials, so they are not afraid of negative environmental influences.
Insulation. It is located between the sheets of steel. Mineral wool, expanded polystyrene or polyurethane foam are used as this element.
The third layer in roofing panels is made of sheet steel. An OSB board is used for wall products.

Features include the following characteristics:

The presence of a connecting lock. The best option is the Z-Lock connection, thanks to which the panels can be stacked vertically or horizontally. The operation of such panels ensures full-fledged tightness of the joints.
The panels can be used as an easily dropable roof - this quality allows the material to be used in buildings with explosive substances.
The presence of stiffeners.

When installing the material, it should be borne in mind that in the absence of overlap between the ridge and the Mauerlat, you can make a slope angle of 5 degrees. If there is overlap, then it is worth increasing the slope to 7 degrees. When planning window openings, the slope should also be increased.

Advantages and disadvantages

Sandwich panels have been in production for over 50 years and quickly gained popularity due to their positive qualities.

The advantages of the products are in the following positions:

Small weight, which is about 40 kg per 1 m2, - this quality makes it possible to mount the material on industrial buildings and other structures with a large area. The fastening of the elements is not accompanied by auxiliary work and reinforcement.
The panels allow you to reduce construction costs, reduce the number of materials and activities that may be required during standard work: installing battens, arranging noise insulation and finishing.
High level of quality, consisting in anti-corrosion properties, good noise insulation, thermal insulation, fire safety, as well as a long service life.
Attractive appearance. Products can be painted in any color.
Sandwich panels are considered an environmentally friendly material.
Easy installation. The material does not require maintenance and additional maintenance during use.

Sandwich panels have numerous advantages, due to which they are often used for individual construction, when arranging a roof for a cottage.

However, some design flaws should be taken into account:

The material does not allow air to pass through. You will need to consider the issue of forced supply and exhaust ventilation to cope with such a problem.
Styrofoam and expanded polystyrene are capable of releasing formaldehyde and styrene particles. This disadvantage can be dealt with by using mineral wool as a heater.

Specifications

Technical characteristics of sandwich panels contain information about the dimensions and weight of products, the level of fire resistance and sound insulation of products. Also in these parameters is the bearing capacity and thermal resistance indicators.

Width and weight affect the BOM. Properly selected panel sizes will help you avoid buying unnecessary amounts of material. The dimensions of the packed lamellas should be taken into account during transportation. The ease of installation is influenced by the mass of products, which depends on the insulation used and the thickness of the material.

Pay attention to the thickness first of all, since the thicker the roofing panels are, the better the temperature inside the building will be maintained. For regions with a calm climate, you can choose a material with a thickness of 50-100 mm.

There are two types of wall panels: products with a width of 1000 mm and products with a width of 1200 mm. The roofing material has a width of 1000 mm.

The length of the wall panels can vary and range from 500 mm to 13500 mm depending on the selected specification. For individual construction, you can choose an increased thickness of the material, which can reach 150 mm or 200 mm for regions with cold climates.

The weight of the structure is influenced not by the metal profile, but by the thickness and type of insulation material.

It is worth considering this indicator when installing. For example, products where the layering devices contain mineral wool, despite the same thickness, will be heavier than foam panels.

Kinds

There are several types of sandwich panels, which differ in their purpose, material, type of thermal insulation material and polymer coating.

According to their purpose, according to GOST, two varieties are distinguished:

wall;
roofing.

Wall products are used in construction works for various purposes. They are also in demand in the construction of low-rise buildings and refrigerators. There are horizontal, vertical and inclined wall slabs. Additionally, it is worth noting that wall panels are used as external and internal partitions, with their help you can lay floors and equip overlap between floors. Often the material is used in the reconstruction of buildings.

The roof type is designed for roof construction.

A separate category contains modern products of element-by-element assembly. In their manufacture, insulation with a high level of efficiency is used with an auxiliary element in the form of galvanized steel with polymer processing.

Protection from wind and water is also provided, making the structure resistant to extreme weather conditions.

Heat insulating layer

According to this characteristic, the products are divided into the following varieties:

mineral wool filler;
fiberglass;
polyurethane foam;
Styrofoam;
with polyisocyanurate foam - such panels are three-layer products, the insulation of which consists of a polyol with a polyisocyanate;
combined.

The last fillers contain two elements: basalt wool and foam. Insulation is placed in layers, parallel to the sheathing.

Sheathing

According to the cladding material, the products are divided into the following types:

Metal sheathing. Most manufacturers offer products made of stainless steel with various polymer coatings. Sheets of metal with different types of profiling are actively used.
GKL, plywood, DSP, fiberboard. Such cladding is used only on one side, and it is customary to leave metal sheets for the second. The panels are suitable for interior partitions. They contain cable channels and wiring.
PVC. The top layer is made of rigid polyvinyl chloride sheets, with insulation between the layers. Panels with PVC sheathing are used during the construction of partitions in the office, as well as for finishing window or door openings.
Paper. The paper can be supplemented with polyethylene or aluminum foil. The products are used for thermal insulation of roofs, walls and foundations. Many buyers choose paper-type sheathing with bitumen impregnation. The material is resistant to steam and does not allow condensation to accumulate.

Polymer coating

Several basic coatings stand out:

Polyester. It is used in all climatic conditions. It is recommended to use the coating inside structures. The thickness of such a coating is 25 microns, the heat resistance reaches 120 degrees. The material has hardness at an affordable price. Glossy and matte polymer of this type are commercially available.
Plastisol. The coating consists of PVC and plasticizers. The polymer can be used for structures that are located outside or inside a building. Often, with the help of plastisol-coated sandwich panels, the roof is equipped. The advantages of the material are resistance to mechanical stress, corrosion and good formability.
Polydifluorionad. The layer thickness reaches 25 microns. It is resistant to high temperature conditions. The coating can withstand a range of -60 to 120 degrees.
Pural. This coating is based on polyurethane. The surface of the layer is matte-silky, characterized by resistance to temperature extremes, corrosion, aggressive substances and ultraviolet rays. Such a roof is often used in harsh climates.

Lock connection

Wall panels and cladding products are equipped with different types of connections:

Thorn-groove - this type is a tongue-and-groove connection.
Secret mount.
Z-Lock. The connection consists of two tenons with slopes and grooves of the corresponding shape. The double closure has a high level of reliability and is preferred for wide panels.

The following connections are provided for the roof:

Roof-Lock. It is able to prevent depressurization of the fold during thermal expansion.
Folded lock. This compound is used in refrigeration equipment.
Eccentric lock. It has a hooked shape. It is built into the ends of the panels, due to which the products can be tightly pulled together.

Connection options for sandwich panels are selected individually for each type of structure. The selection is based on factors such as frame length and thickness, layout type, roof slope and axle dimensions. The set of the kit also depends on the type of node. Manufacturers offer 27 types of panel mounts, including valleys, parapet mounts, gutters, roof and wall panels, and overhangs.

Preparation for styling

Sandwich panels are easy and quick to install. To eliminate problems during installation, experts advise to carry out preparatory measures before laying.

Assembly technology requires attention to several indicators:

Minimum slope.
The main dimensions of the roof.
The readiness of the frame part. During the installation of products, distortions or tilts must be excluded. Each surface must be parallel or perpendicular.
It is necessary to clarify the order of installation of the panels, since they have different sizes. First you need to make a calculation, and only then start installation.
Arrangement of stops for the bottom row. You can use a bar, a metal profile, corners. They are attached to beams or plinths using heavy-duty self-tapping screws and anchors. Place the stops horizontally and check the correct location with a level. The appearance of the structure and the quality of the assembly depend on the actions.
Arrangement with waterproofing.
Preparation of tools necessary for work.

It is best to use a saw with small teeth in work - it is forbidden to use a grinder. You should also take care of the availability of connecting material for products in advance. There are different connecting components for each thickness.

During drilling, you need to create a right angle, so you need to use squares during work.

To install a sandwich, you will need to prepare construction equipment. It should be borne in mind that without a crane it will be quite difficult to lift the panels. Special equipment should be chosen with a grip that will not damage the surface of the plate.

Preparatory measures are a mandatory procedure, without which a high-quality installation is impossible, therefore, special attention should be paid to preparation.

Installation methods

To independently install sandwich panels, you will need to comply with SNiP and PPR. You should also use the technological map and drawings in your work.

Installation has its own nuances. It is not a traditional skate that needs to be created, but an element complemented by an internal bar. As a result of the actions between the counter plates, which are located under the ridge, a void is formed. It should be filled with foam for assembly work. The cut foam is covered with polyurethane gaskets, on which the plates are later fixed.

As a result, the following elements will be created:

profile gaskets;
ridge and ridge strips.

It is imperative to ensure that the distance between the roof rafters matches the width of the panels. Compliance with this rule allows you to exclude the fitting and trimming of boards and saves material costs.

Panel assembly instructions.

The first step is to lay the bottom slab and then attach it to an auxiliary beam that supports the rafters. You can use stacking from the bottom up or in horizontal rows. The choice of installation scheme depends on the type of structure. In the future, you need to attach the roofing panels to the rafters - it is unacceptable to attach to the ridge.
Then you need to start sealing. In order for the sealing of the joints to be of high quality, a sealant should be added to the lock connection. The measure excludes the formation of temperature bridges, and also guarantees a high quality of the installation. If a silicone sealant is used, it must be free of acids, otherwise corrosion and surface degradation will occur.
After the panels are at the installation site, you need to remove the protective cover. You can remove the film from the entire product or clean only the area where the attachment will be made. Two grippers are required to lift and feed the slabs - one gripper is not allowed, even if a short panel is used. Compliance with this rule will ensure a flat fit, on which there will be no distortions.

Fastening sandwiches:

three self-tapping screws of the last plate should be screwed into the roofing girder through the wave formed by the stiffeners;
the step of the runs from the end of the plate to the first self-tapping screw must be at least 50 mm;
the rest of the plates can be fixed with two self-tapping screws.

The panels can be installed on different bases.

Metal frame. Fastening to metal structures is carried out using self-drilling screws. To carry out this procedure, you will need to make holes of a smaller diameter in the supporting elements - in the future, a screw will be screwed in here.
Guides made of wood. Simple self-tapping screws for working on wood surfaces are suitable to ensure fixation.
Concrete base. Dowels are used, which should be inserted into previously prepared holes. The panel is then secured with anchors.

Experts recommend for work to choose self-tapping screws made of steel, on which there is a sealing rubber made of synthetic rubber. The places where the panels are connected are recommended to be reinforced with a trapezoidal metal interception.

Self-tapping screws must enter the purlins at right angles - even slight distortions are not allowed. At the same time, dents that appear from the twisting of the self-tapping screw must not be allowed.

Operating rules and repair

The operating rules consist in periodic maintenance of the panels.

This will require:

Remove the protective film within two weeks of installation.
Systematically clean the gutter and roof from debris. Use mild detergents in your work. Stubborn dirt can be wiped off with soapy water and then washed off with plain water.

Many users are faced with thermal deformations, which manifest themselves in the form of transverse folds, tears or shears in the fastener.

The reasons for the deformation are as follows:

Use of dark colored panels in hot climates.
Incorrect calculations of the load during the operation of the product with hygroscopic insulation. The mass of the material increases with the collection of moisture, the load increases, which further leads to the collapse of walls or roofs, as well as to the deformation of products.
If there is no expansion joint in the project, then in the process of use the lock is deformed, the geometry of the products is distorted, and users may be faced with the fact that the roof and the junction to the deflector are leaking.
Unevenly aligned panels vertically during docking lead to distortion of the locking mechanism.
Unevenly twisted self-tapping screws will lead to curvature of the sheets and loss of tightness.

To minimize the likelihood of product deformation, some rules should be followed:

you need to choose products in a lighter shade;
it is necessary to use a two-support mounting option;
panels with a maximum length not exceeding 6 m should be used.

Repair of sandwich panels

During the use of the roof, you may encounter damage to the polymer coating. If this defect is found, you should quickly proceed to the restoration process - painting the product. To do this, you need to choose a paint of the required shade, which is suitable for working with a polymer coating.

Based on the depth of the damage, the paint is applied in one or two layers. To paint over a small area, you need a thin, soft brush. If the panel is to be painted completely, a spray gun is used. Before the event, remove the rust and sand the area. Deep damage is treated with a primer.

The impact of the external environment can damage not only the outer layer, but also the heat-insulating material.

To exclude the formation of complex defects, experts recommend systematically checking the condition of products by tapping. Diagnostics should be carried out in the most unprotected places of the structure.

After the location of the damage is found, it is necessary to study its boundaries in order to calculate the volume and type of repair measures. In some cases, minor surface damages hide significant defects in the inner layer - if such problems are found, it may be necessary to dismantle the damaged panel. However, external damage does not always spoil the structure of the material, and users carry out the usual restoration of the appearance of the sheet.

The most complex and costly measures will be required when laminating sheets. It is necessary to quickly start restoring the starting mechanical properties of products. If panels with mineral wool insulation were purchased, they should be replaced with identical raw materials.

Manufacturers

Sandwich panels are in great demand, therefore, there are many brands on the Russian market that sell this material for construction.

According to customer reviews, the following manufacturers are considered the best:

"Lissant". The brand has been known since 2008 and currently has several production lines located in different cities.

Speed and quality in construction are two seemingly completely different concepts that do not intersect and do not interact in the complex process of building construction. However, modern technologies are breaking the established stereotypes.

Today, the most popular and practical building materials are sandwich panels. They make it possible to implement architectural solutions of varying complexity in record time.

Sandwich panels make the building warm, durable and aesthetically pleasing. There are different types and purposes: it all depends on the thermal insulation insulation and the material from which the framing sheets are made.

There are wall and roofing. When choosing a material, you need to know how they differ, what is their operational feature and what is their advantage? How not to get lost in a wide range of manufacturers and follow the path of least resistance?

Dimensions and weight

The dimensions of the sandwich panels are standard:

Length - 1.8 - 13 m.
Width - 1.2 m.
Thickness - 50-250 mm.

The weight of the material depends on the thickness of the used insulation and cladding sheets. Basalt fiber slabs are the heaviest heat insulators. The reason for this is not only the specific gravity of the insulation itself, but also the fact that to create high quality sandwich panels, it is necessary to use at least 80 cm of mineral wool.

When calculating the weight, the density of the insulation is taken into account. Consequently, mineral wool has the highest density - 110 kg per cubic meter, and the smallest - with a density of 25 kg per cubic meter. To calculate the total weight, you need to know the mass of the cladding sheets, the thickness of the insulation layer and the dimensions of the panel itself.

Sandwich panels with a thickness of 50 mm based on mineral wool and galvanized sheets weigh 15.2 kg, with a thickness of 200 mm - 38.2 kg. With 50 mm expanded polystyrene, the panel weighs 9.8 kg, with 200 mm - 14.8 kg. With polyurethane foam of 50 mm, the weight reaches 11.2 kg, with 200 mm - 22 kg.

Price, advantages and disadvantages

The cost of a building material depends on its purpose, thickness and insulation used.

Prices for facade sandwich panels with mineral wool start at 800 rubles per square meter. They can reach 1,500 rubles, depending on the color and amount of the heat insulator.

Wall panels have a cost in the range of 1100-2150 rubles.

The frame can be damaged due to strong condensation and dew point.
Over the years, the panels dry out and shrink in volume, which is why they lose their performance.
can release toxic formaldehyde.

Description and scope

With such high performance characteristics and unique design capabilities, sandwich panels have confidently taken their niche in construction.

Is a material that consists of two rigid sheets and insulation that meets various requirements. The main purpose is housing construction for the creation of pre-fabricated buildings. Such panels are called with the SIP or SIP prefix.

They have a hermetically sealed structure. The basis for such panels is OSB boards with expanded polystyrene layer. Its cost also depends on the thickness of such a panel.

For commercial purposes, they are used in the construction of supermarkets, shopping centers, sports complexes, industrial workshops.

You may have noticed more than once how tall car dealerships, new car washes and huge sales areas appear before our eyes. This is the construction technology with the use of sandwich panels.

For the first time, the material was produced in the USA for the construction of a one-story building. Initially, the technology had more disadvantages than advantages, however, the panels looked very attractive and were easy to use.

Over time, the construction process has been improved and brought to the level of mass consumption. In Russia, the material found its use in 1974. Not much time has passed, and the percentage of distribution in the market has reached 40.

They are used for the implementation of such projects:

Trade and sports pavilions.
Constructions for shops and fast food.
Warehouse and industrial buildings.
Agricultural buildings.
As office partitions.
For roof installation.
For cladding buildings ..

Sandwich panels provide high-quality insulation and can be used as a material for building renovation. In the future, the production of panels that could independently generate electricity is being considered. For this, photocells are built into the structure of the sandwich.

Varieties

Sandwich panels differ depending on the insulation used.

The following materials are used:

Styrofoam or Styrofoam

It has a cellular structure. Sandwich panels with a similar insulation are relevant in the production of industrial facilities, retail outlets and storage chambers. It is also used in the recently popular "Canadian technology", which allows you to create homes quickly and reliably.

Pressed mineral wool

Popular and demanded material. Mineral wool panels are used in the construction of simple structures where speed and simplicity are important.

They are easy to repair, have high thermal insulation qualities and do not burn when exposed to open fire. They easily tolerate low and high temperatures, do not deform, and have excellent noise insulation properties. They do not respond to aggressive environmental influences.

Polyurethane foam

It combines very valuable qualities: strength and lightness. These panels are durable and waterproof. Has high thermal insulation properties.

A distinctive feature of the material is the fact that polyurethane foam is resistant to the appearance of fungi, mold, does not lend itself to attack by rodents and insects. It is fireproof, therefore it has wide industrial and domestic use. The only drawback is the high cost of such panels.

Fiberglass

A material for a specific purpose, which consists of many thin glass threads. Soundproofing properties are especially appreciated in fiberglass panels. It does not burn, it is easy to transport and install without much difficulty. Resistant to chemical attack. However, such panels can only be used in environments where the temperature does not rise above 40 degrees.

Polypropylene

It has a honeycomb structure and is resistant to moisture. Not susceptible to chemicals. It has light weight and low thermal conductivity. Such insulation during the production of sandwich panels must be protected from fire by choosing the right facing material.

Also, the panels may differ depending on the type of coating. The structure can be made of two different cladding materials or have the same origin. The outer coating determines the main functional properties of the sandwich panels.

There are the most common materials used as cladding:

Zinc plated steel- the most popular and available material that protects panels from corrosion, has a long service life and is easy to handle.
Pvc- relevant for indoor use.
OSB- the basis of panels for prefabricated structures.

It should be noted that today, the potential volume of sandwich-panel production in Russia is fully consistent with consumer demand. Many companies have appreciated this product, including the convenient dimensions of the sandwich wall panels and their cost. Therefore, an annual increase in production by 20 - 25% is envisaged.

They are a unique building material that allows the developer not only to significantly speed up work, allowing them to meet deadlines, but also to reduce the financial costs of repair and construction work. At the same time, the labor intensity of the work performed is significantly reduced.

Dimensions of wall sandwich panels

As with any other building material, the dimensions of the sandwich panel can vary. Manufacturers produce products up to 14 meters long. In this case, the thickness of the finished mounting structure can vary between 5 and 25 centimeters, and the width in the range of 100-102.5 centimeters.

Standard dimensions of the material are given in the table:

The great popularity of sandwich panels is due not only to the excellent characteristics of the building material. Products cannot be called fragile, they stand out for their increased resistance to many adverse influences, strength, have excellent insulating properties, including thermal, relatively small mass. At the same time, the finished product is moisture resistant, which once again saves the building from the appearance of various kinds of stains, covering the slopes from negative external influences.

Today, sandwich wall panels can be produced in two-layer and three-layer. The products consist of a heat-insulating material that acts as an internal filler and external cladding sheets.

As an insulating material, many manufacturers, as a rule, use expanded polystyrene, basalt fiber, polyurethane foam and glass wool.

Based on the purpose and size, wall panels can be sheathed with different finishing materials, be it steel, ceramics, aluminum, chipboard, or fiberboard. The most common option is a steel finish with polyester, pural and plastisol.

At the same time, the external finish gives the finished structure an aesthetic appearance and greater rigidity.

Properties of the outer layer of sandwich panels:

The color scheme is based on RAL.
The decorative layer is polyester with a thickness of 0.25 millimeters.
The main material is hot-dip galvanized cold-active steel with a thickness of half a millimeter.

In addition to sound and heat insulation characteristics, the filler guarantees the material proper fire safety:

Styrofoam.
Mineral wool.

The dimensions of the sandwich panels make it possible to actively use them not only as a building envelope in the construction of walls, they are also often used for the reconstruction and decoration of old buildings.

Material features:

No paint work required.
Installation can be carried out both to concrete surfaces and to brick ones.
Renowned manufacturers use innovative technology to manufacture products.
The panels do not need additional refining and insulation works.

If it is made for slopes, then the product can be installed after placing the window. This kind of work does not require plastering, and therefore does not take much time and effort.
The work is accompanied by a minimum amount of waste.
Refractoriness of the material is achieved through the use of an ultraviolet stabilizer.

Material price

The cost of wall sandwich panels may vary depending on the following parameters:

The presence of a protective layer;
Place of manufacture;
Multi-layer or single-layer construction;
Product characteristics;
The material used in the production;
The area of use of the finished structure.

The dimensions of the material, namely the thickness, also have a serious impact on the cost, while the larger the panel, the greater the load it can withstand. Along with this, many other characteristics increase, for example, sound insulation, hygroscopicity, etc.

It is important to emphasize that today the volume produced by companies in Russia fully meets the demand. Many developers have appreciated sandwich wall panels as a building material, including both cost and size. Proceeding from this, the volume of products produced annually increases by 20-25 percent.

What is a sandwich panel? This term refers to a multi-layer building material that is used for the construction of frameless structures. During construction, the elements of the panels are interconnected with a castle joint, forming a solid monolithic surface.

The first sandwich panels appeared on the construction market in 1930 year. The inventor of the design is engineer Lloyd. First used for assembly, the panels immediately began to gain worldwide popularity, allowing you to quickly erect buildings for various purposes. Russian manufacturers have mastered the technology in the 90s last century.

Standard sandwich panels consist of several layers: external cladding and an insulating layer between them. The main components are hot-pressed or bonded with a polyurethane-based adhesive.

External cladding

Two-component adhesive layer No. 1

Two-component adhesive layer No. 2

Trapezoidal mineral wool slats

Internal cladding

Protective film

Roof lock

Structural slats of mineral wool

Due to the composite structure, sandwich panels have a lot of undeniable advantages. In particular, the compacted material has a minimum weight, which significantly reduces the load on the foundation. They have sandwiches and a high level of thermal insulation, while the insulation layer is reliably protected by the outer cladding, so the panels do not lose their properties over time.

Types of profiling of external cladding of panels

What are they? Types, characteristics and sizes

Sandwich panels are divided according to several criteria, which determines their characteristics and application features.

By appointment

By purpose, the material is divided into three groups:

These are usually sturdy products designed for vertical installation. The outer cladding is made of durable polymer-coated material, the color palette includes a wide range of shades. A lock system is used to connect the wall elements to each other. Z-LOCK.

Such a connection provides a hermetic joining of panels, which excludes the formation of cold bridges, reliably protects the insulation from any external influences. It is worth noting that for additional protection of butt joints, additional elements, sealant, construction tape and polyurethane foam are used.

Dimensions (mm)

In terms of its structure and composition, the material resembles wall counterparts, however, there are some differences. For example, the lock connection belongs to the class F-LOCK, which prevents moisture from entering the roof. For these purposes, a pronounced profile of the external cladding is also provided.

To protect the panels from aggressive environmental influences and direct exposure to ultraviolet rays, anti-corrosion spraying is used. It should be noted that panels of this category are a complete element of the roof, therefore they do not need additional protection of the joints.

Dimensions (mm)

It should be noted that according to the GOST standards, some deviations in the dimensional grid are allowed, which does not classify the panels as a marriage. It is important to understand that the given standard sizes are relevant only for domestic manufacturers. In Europe, there are other standards, therefore, sandwich panels produced abroad may differ from Russian standards.

Corner

As the name implies, such panels have a rather limited area of application. They are used to protect the corners of buildings from moisture, improve the appearance. The panels are mounted on the corner slopes of the wall structures, which provides reliable thermal insulation.

Comparative load table

The picture above shows options for facade cladding for the so-called sandwich panels of element-by-element assembly.

If we talk about solid sheets, then the following materials are used here:

Galvanized or polymer-coated stainless steel.

Combined materials, where one metal sheet is replaced by plasterboard or DSP (cement particle board). Such options are usually used to equip internal partitions.

Both layers are made of PVC.

The outer layers are made of special paper, aluminum foil or polyester. Such products are usually used for additional thermal insulation of floors or foundations.

Usually manufacturers use the following materials:

Minvata... It is a fibrous composition obtained from silicate magma and metallurgical slag. The material is absolutely non-flammable, but very sensitive to humid environments. When installing such panels, personal protective equipment must be used, special attention is paid to the tightness of the joints. In addition, sandwich panels with mineral wool have a rather large structural mass.

Glass wool... In terms of its properties, the material is almost identical to mineral wool. However, due to the large size fibers, such panels are more resilient and therefore more resistant to dynamic loads.

Polyurethane foam... This material has absolute environmental safety, is resistant to any external influences, has excellent thermal insulation properties and moisture resistance. The only drawback of such a filler is flammability.

Expanded polystyrene... Sandwich panels with such an insulating layer are often used in the construction of commercial establishments, arrangement of refrigeration chambers. The material has a porous structure, which ensures reliable insulation of the interior. However, expanded polystyrene has a relatively low strength, which negatively affects its durability.

Comparative characteristics of panels with different types of insulation

Sandwich panels	Filler type	Heat transfer resistance (sq.moC / W)	Thickness (mm)	Specific weight of filler (kg / m3)	Moisture absorption
Wall	Polyisocyanurate foam
Roofing	Polyisocyanurate foam
Wall	Expanded polystyrene
Roofing	Expanded polystyrene
Wall	Basalt mineral wool


Roofing

Knowing these features, it will not be difficult to select a sandwich panel in accordance with individual requests.

RAL standard colors

Weight

The structural weight of sandwich panels directly depends on the type and thickness of the heat-insulating layer. In addition, the density of the insulation plays a key role. For example, for mineral wool, this indicator is 110 kg / m2, for foam - 25 kg / m2... Accordingly, subject to standard sizes, the weight of wall sandwich panels with mineral wool can vary within 16-39 kg... Similar products, where foam is used as insulation, will weigh 12-17 kg.
