Dimensions of wall sandwich panels. Panel sandwich: description, types, size, purpose, photo, application. Description and scope
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 financial costs for repairs and construction works. 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 a sandwich panel may vary. Manufacturers produce products up to 14 meters long. At the same time, 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.
The standard dimensions of the material are given in the table:
The great popularity of sandwich panels is explained not only by the excellent characteristics of the building material. Products cannot be called fragile, they stand out increased resistance to many adverse effects, strength, have excellent insulating properties, including thermal, relatively small mass. Together with that finished products differs in moisture resistance, which once again saves the building from the appearance of various kinds of spots, covering the slopes from negative external influences.
Today wall sandwich panels can be made two-layer and three-layer. Products consist of heat-insulating material, which acts as an internal filler, and external facing 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 dimensions, wall panels can be sheathed with various finishing materials, whether it be steel, ceramics, aluminum, chipboard, or fiberboard. The most common option is a steel finish with polyester, pural and plastisol.
At the same time, the exterior finish gives finished structure aesthetic appearance and greater rigidity.
Properties of the outer layer of sandwich panels:
- The color scale is under construction on the basis of RAL.
- Polyester with a thickness of 0.25 millimeters acts as a decorative layer.
- 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 panel make it possible to actively use them not only as a building envelope in the construction of walls, they are also often used in the reconstruction and decoration of old buildings.
Material Features:
- No need for paint work.
- Installation can be done as concrete surfaces, and to brick.
- Well-known manufacturers produce products using innovative technology.
- Panels do not need additional work on refining and insulation.
- If it is made for slopes, then you can install the product after placing the window. This kind of work does not require plaster, and therefore does not take much effort and time.
- Works are accompanied by a minimum amount of waste.
- The fire resistance 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 production;
- 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 are also increased, for example, sound insulation, hygroscopicity, etc.
It is important to emphasize that today the volume produced by companies in Russia fully satisfies the demand. Many developers have appreciated wall sandwich panels as a building material, including both cost and size. Proceeding from this, the volume of output annually increases by 20-25 percent.
What is a sandwich panel? This term refers to a multilayer building material that is used for the construction of frameless structures. During construction, the elements of the panels are interconnected by interlocking, 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 build buildings for various purposes. Russian manufacturers have mastered the technology in the 90s last century.
Standard sandwich panels consist of several layers: an outer cladding and an insulating layer between them. The main components are joined together by hot pressing, or bonded with an adhesive based on polyurethane.
External cladding
Two-component adhesive layer No. 1
Two-component adhesive layer No. 2
Trapezoidal mineral wool slats
Internal lining
Protective film
roof lock
Structural mineral wool lamellas
Due to the composite structure, sandwich panels have a lot of undeniable advantages. In particular, the pressed material has a minimum weight, which significantly reduces the load on the foundation. Sandwiches also have a high level of thermal insulation, while the insulation layer is reliably protected by the outer lining, so the panels do not lose their properties over time.
Types of profiling of external facing 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:
Usually these are durable products designed for vertical installation. The outer cladding is made of durable polymer-coated material, the color palette includes wide range of shades. A lock system is used to connect wall elements to each other. Z-LOCK.
Such a connection ensures hermetic joining of the panels, which eliminates the formation of cold bridges, reliably protects the insulation from any external influences. It should be noted that for additional protection of butt joints, additional elements, sealant, construction tape and mounting foam are used.
Dimensions (mm)
In its structure and composition, the material resembles wall counterparts, however, there are some differences. For example, a lock connection belongs to the class F-LOCK which prevents moisture from entering the roof. For these purposes, a pronounced profile of the outer lining is also provided.
To protect panels from aggressive influences environment and direct exposure to ultraviolet rays, anti-corrosion coating is used. It should be noted that the panels of this category are a complete element of the roof, so they do not need additional protection of the joints.
Dimensions (mm)
It should be noted that according to GOST standards, some deviations in the dimensional grid are allowed, which does not classify the panels as defective. It is important to understand that the given sizes are relevant only for domestic manufacturers. In Europe, other standards apply, so sandwich panels manufactured abroad may differ from Russian standards.
corner
As the name implies, such panels have a rather limited scope. They are used to protect the corners of buildings from moisture, improve appearance. The panels are mounted on the corner slopes of wall structures, which provides reliable thermal insulation.
Table of comparative loads
The picture above shows the façade cladding options for the so-called piece-by-piece sandwich panels.
If we talk about solid sheets, then the following materials are used here:
Galvanized or stainless steel with polymer coating.
Combined materials, where one metal sheet is replaced with drywall or DSP (cement particle board). Such options are usually used for arranging 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.
Typically, manufacturers use the following materials:
mineral wool. This is a fibrous composition obtained from silicate magma and metallurgical slag. The material is completely incombustible, but very sensitive to damp environments. When installing such panels, means must be used personal protection, 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. According to its properties, the material is almost identical to mineral wool. However, due to the large size fibers, such panels have greater elasticity, respectively, are 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.
Styrofoam. Sandwich panels with such a heat-insulating layer are often used in the construction of commercial establishments, the arrangement of refrigeration chambers. The material has a porous structure, which provides reliable insulation interior spaces. However, expanded polystyrene has a relatively low strength, which negatively affects its durability.

The weight
Structural mass of sandwich panels directly depends on the type and thickness of the heat-insulating layer. In addition, the density of the insulation also plays a key role. For example, for mineral wool, this indicator is 110 kg/m2, at polystyrene - 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 a heater, will weigh 12-17 kg.

Quality materials for roofing are distinguished by characteristics that contribute to their efficient and durable functioning on the roof. It is these properties that roofing sandwich panels have, which, moreover, differ from wall elements. First of all, this concerns the design features, internal and overall dimensions of these plates, allowing simple and quick installation.
Consumer parameters of sandwich panels for roofing
Design features
Roofing sandwich panels, the dimensions of which are standard, based on the specific purpose and installation area, structurally have some differences compared to wall panels. They are a 3-layer "pie", consisting of external metal profiles of various shapes and insulation in the form of basalt (mineral) fiber or expanded polystyrene, glass wool or polyurethane foam.
- Due to the peculiarities of the dimensions and the trapezoidal shape of the main stiffeners of the slab, they can withstand loads from snow of the calculated thickness.
- Sheets on the outside are covered with zinc or an additional polymer, which significantly increases the anti-corrosion properties and the service life of roofing products.
- The protective coating of the profiles is highly resistant to the effects of an aggressive environment, in particular acid rain and ultraviolet radiation.
- A wide range of polymer colors allows you to choose desired color based on design considerations and reflective characteristics.
- The thought-over design of locks provides reliability and tightness of connection.
- Installation of sandwich profiles is simple, easy and fast.
Specifications
Sandwich roof lamellas are covered with different profiled sheets on the outside - the height of the external stiffeners is 4.0 cm, the internal ones - 0.15 cm. The above heaters have high noise and heat insulation properties and are light in weight. The second parameter plays a significant role in the installation. In addition, they are environmentally friendly, durable, and also reduce the cost of construction, since there is no need for a device. roofing cake". The main dimensions of roof sandwich panels are as follows:
- the length of the slabs is limited to 16.0 m;
- the width of the elements is 1.0 m;
- the thickness of the panels ranges from 4 to 20÷30 cm.
- the weight of products rarely exceeds the limit of 40 kg.
Geometric characteristics of Teplant sandwich roof panels
Teplant "sandwich" elements are manufactured in automatic mode and consist of 3 layers: a basalt heat insulator (TU 5762-007-01395087-2011, rev. 1) and 2 thin-sheet galvanized profiles coated with 1st polymer - polyester , puralom, plastisol or PVDF (GOST R 52146-2003). The range includes Universal and Concept roofing slabs - the latter are used in regions characterized by a high layer of snow cover in winter.
The main characteristics of sandwich panels include the following parameters: width, length, thickness, weight, fire resistance, sound insulation, bearing capacity of sandwich panels and thermal resistance. The required specification of the panels depends on the width and length; correctly selected dimensions of wall and roof sandwich panels allow avoiding excess material and unnecessary trimmings. You also need to take into account the dimensions of the packed lamellas during transportation. The ease of installation is primarily affected by the weight of the panels, which depends on the thickness of the panels and the type of insulation. The thickness of the sandwich panels is chosen first of all, based on the thermal insulation index; the thicker the panel, the better the temperature inside the building is maintained.
Sandwich panel dimensions: width, length
- Wall sandwich panels are available in two versions: 1000 mm wide and 1200 mm wide.
- Roof sandwich panels have a width of 1000 mm.
- The length of wall and roof panels can be anything from 2000mm to 13500mm depending on the required specification.
Sandwich panel weight
The weight of sandwich panels depends on the thickness of the panels and the type of insulation, this should be taken into account during installation. For example, panels with mineral wool insulation with the same thickness will be heavier than panels with expanded polystyrene.

Characteristics of heaters. Soundproofing sandwich panels
The thermal insulation properties and fire resistance of sandwich panels depend on the insulation used. Sound insulation depends on the thickness of the panels.
Therefore, the choice of insulation should be based on:
- building fire safety requirements - for example, administrative and residential buildings are built only from panels with mineral wool insulation;
- the purpose of the building - in the construction of refrigeration and freezers, polyurethane foam or polyisocyanurate foam is used;
- economic feasibility - in terms of price / quality ratio, expanded polystyrene is the best choice as a profitable light and warm insulation.

A sandwich panel is a building material, the outer sides of which are made of a solid material, most often metal, and the inner side is made of insulation. They got their name due to the fact that the layers resemble a sandwich (eng. sandwich ["sænwɪʤ]) - the same materials from the outside and one more from the inside. For the first time, sandwich panels were used in 1930 in America during the construction of a residential building. Later, a massive panel production. Russian Federation this building material began to be manufactured in 1974, and it quickly occupied its niche in the construction market.
Sandwich panels are often used in construction
Main characteristics
Basically, sandwich panels are used for the construction of low-rise buildings for commercial, industrial or other purposes. Due to the "official" appearance, it is rarely used in the construction of residential buildings. Most often this finishing material designed for walls. Installation is carried out by fastening to a metal frame with self-tapping screws.
One of the areas of application of sandwich panels is the construction industrial buildings Source 2gis.ru
There are several types of panels.
Sandwich panels for exterior walls. They are made of metal sheets and insulation. They are mainly used for the construction of partitions, cladding of the walls of the building, for the purpose of insulation.
Roof panels. Used to cover roofs. Long term in use. They are made of fireproof materials, retain heat for a long time and isolate loud street sounds. Fastening is carried out according to a unique technology that protects against deformation in the warm season.
Three-layer panels. Convenient to use. Installation of such plates occurs quickly, without any difficulties. There is no need to strengthen the supporting structures of the building. Manufactured from galvanized steel, polymer coating is possible. Currently, this type of sandwich panels is used most often. This is the most modern building material. Moreover, the use of three-layer panels significantly reduces financial costs.
Corner sandwich panels. Used to create a complete image of the building. They can be semi-circular or angular. Produced from heat-resistant fireproof material.

The panels are varied color scheme, which is defined by international color standards. The color must be chosen according to the climatic conditions. It is necessary to take into account the ability of light reflection and light absorption of the material. The service life of the building directly depends on this.

Types of insulation for sandwich wall panels
First of all, external wall panels are usually distinguished by the internal composition of the insulation:
polyurethane foam. The material is practically not subject to corrosion and deformation. Resistant to thermal and mechanical influences. It is a pure ecological product. Durable enough. The cost of such panels is quite high. In this case, the material is not safe in case of fire.
Styrofoam. It has high heat and sound insulation. Not exposed to thermal influences. Eco-friendly and lightweight material. Retains its shape with prolonged contact with water. The advantage is the ability to install panels in the cold season. The main disadvantage of the filler was such characteristics as fire hazard, color change when exposed to sunlight, changes shape at temperatures above 1000⁰С, causes various allergic reactions.
Polyisocyanurate foam filler. Leading material among sandwich panels. Environmentally friendly, not subject to corrosion and deformation. Possesses the minimum thermal conductivity, elasticity. Durable, fire resistant and durable. Of the shortcomings of the building material, one can only distinguish its high cost.
Mineral wool filling. The advantages of insulation are incombustibility, good sound insulation. The material is environmentally friendly. It is not subjected to thermal deformation. In contact with metal, the possibility of corrosion is reduced to zero. It is easy to use and install. Panels filled with mineral wool also have a number of negative characteristics. First of all, it's harmful. When installing such sandwich panels, you must use a respirator. Over time, the material loses its heat-insulating properties. Work with panels is possible only in good weather, as mineral wool is not a moisture-resistant material. In contact with water, the panel may delamination. Sufficiently large weight requires additional strengthening of the supporting structures.
Mineral wool eco-friendly material, but eventually loses its properties Source s-paneli.ru
fiberglass insulation. The filler is similar in composition to mineral wool, but differs significantly in properties. The advantages of this material are incombustibility, sufficiently high heat and sound insulation. The product is light, elastic, durable and environmentally friendly. Of the minuses, one can single out the high absorbency of liquids, the inability to use at high temperatures, and deformation during a sharp change in temperature. May cause severe allergic reactions if inhaled.
Combined fillers. The composition of the filler includes a mixture of various building materials. Basically, it is mineral wool and expanded polystyrene.

Types of outer cladding sandwich panels
Just like the internal filler of sandwich panels, their outer layers are made of various materials.
Paper. The addition to the paper is aluminum foil or polyethylene. You can find panels in which paper is impregnated with bitumen. Panels with such sheathing have a relatively low price and are economical to use.
Metal. Mostly thin stainless or galvanized steel is used. The metal is covered with aluminum foil, cloth or paper. This serves as a protective function of the upper layers of the panel.
PVC. Between the PVC sheets there is a layer of insulation. Such panels are used for the construction of partitions, finishing door and window openings.
Drywall, fiberboard, plywood. The product is sewn on both sides. different material. Used in construction office partitions. Convenient if necessary to hide the wiring.

polymer coating
Sandwich panels also differ in the type of polymer coating. Let's take a look at some of the main types.
Pural (pural). The material is resistant to sudden temperature changes, does not react when exposed to ultraviolet rays. It is mainly used for exterior cladding of buildings.
PE (polyester).
Polydifluorionad. The coating is resistant to aggressive chemical compounds, changes in air temperature and external mechanical influences.
Plastisol. Panels with such a coating are used not only for exterior finish buildings, but also for the interior.
Panels coated with plastisol can be used both indoors and outdoors. Source usider.it
Panel dimensions
The width of the sandwich wall panels can be different. It depends on the material from which the product is made. Width varies from 100 to 103 cm. Thickness from 5 to 25 cm. Length finished product can reach 14 meters.
