Sandwich panel sheet dimensions

Sandwich panel sheet dimensions Dimensions of wall sandwich panels and how they affect the choice

What is a sandwich panel? This term is called a building multilayer material, which is used for the construction of frameless structures. During construction, panel components are fastened together with a lock-type connection, creating a monolithic strength of the surface.

The first panels of this type appeared on the construction market in 1930. The engineer Lloyd became the creator of this design. First used for assembly, the panels were immediately able to gain worldwide popularity, making it possible to quickly build for various purposes.

Russian manufacturers were able to master the know-how in the 90s of the last century.

Properties and characteristics. Panel composition

Conventional sandwich panels are made of two or three layers - external cladding and an insulating layer between them. The main elements are bonded together by hot pressing, or they are bonded with a polyurethane-based adhesive. The composition is as follows:

  • Sandwich panel sheet dimensions Construction lamellas from mineral wool.

  • Roof lock.
  • Protective film.
  • Internal cladding type.
  • Trapezoidal mineral wool slats.
  • Two-component adhesive layer # 2.

  • Two-component adhesive layer # 1.
  • External cladding.

Due to the composite structure, sandwich panels have many undeniable advantages. In particular, compressed-type materials are lightweight, and this greatly reduces the load on the base. Also, these panels have a high level of thermal insulation, and at the same time, the insulation layer is perfectly protected by the outer cladding, which means that the panels do not lose their properties over time.

Varieties, sizes and characteristics

Sandwich panels can be divided according to several criteria, and this determines their parameters and features of use.

By type of facing

As a rule, these are products of great strength that are needed for vertical installation. The outer cladding is made of durable polymer-coated material, the color palette will mean a wide range of shades. The Z-LOSK locking system is used to fasten the wall elements. This connection will ensure a tight joining of the panels, and this will exclude the appearance of cold bridges, perfectly protects the insulation layer from all external influences.

It should be noted that for additional protection of joints, additional elements, sealant, polyurethane foam and construction tape are used.

Now let's talk about roofing panels. In its composition and structure, the material will resemble wall counterparts, however, there are certain differences. For example, a lock-type connection is of the F-LOSK class, which will prevent moisture from entering the roof.

For such tasks, a pronounced profile from the external cladding is also foreseen. In order to protect the panels from the negative influence of the environment and 100% penetration of ultraviolet rays, anti-corrosion spraying is used. It should be noted that this category of panels is a complete roof element, and therefore will not need additional butt protection. Here is a size chart.

It is important to note that that according to the GOST standards, certain deviations in the grid of dimensions are allowed, which does not classify the panels as defective. It should be remembered that the given typical dimensions are relevant only for domestic manufacturers, and other standards apply in Europe, and therefore sandwich panels made abroad may differ from the standards of the Russian Federation.

There are also angular ones, as the name suggests, such materials have a rather limited area of ​​use.

They are used in order to protect the corners of buildings from water, and also to improve the appearance. Wall panels are required to be installed on corner slopes of wall structures, which will provide reliable thermal insulation.

By the type of cladding

The photo above shows different options for cladding of the facade type for the so-called sandwich panels of the element-by-element assembly. If we talk about solid sheets, then the following materials are used:

  • Sandwich panel sheet dimensions Stainless or galvanized steel with polymer spraying.
  • Combined type materials, where one sheet of metal is replaced by plasterboard or cement-bonded particle board.

    These options are usually used in order to equip internal partitions.

  • Both layers are made of PVC.
  • The outer layers are made of specialty paper, polyester or aluminum foil. Such products are usually used for additional thermal insulation of a foundation or floor.

And one more section of the classification.

By the type of thermal insulation layer

As a rule, manufacturers use the following list of materials:

  1. Mineral wool - It is a fibrous type material that is obtained from silicate magma and metallurgical type slag. The building material has ideal non-combustibility, but is extremely sensitive to a wet environment. When installing these panels, personal protective equipment must be used, and special attention is paid to the tightness of the joints. Besides, sandwich panels with mineral wool have a rather large structural weight.
  2. Glass wool - by individual properties, the material is almost 100% similar to mineral wool.

    What is the size of glass wool sandwich panels? Standard, but due to coarse fibers, these panels have a higher degree of elasticity, respectively, they are more resistant to dynamic loads.

  3. Polyurethane foam. This material has complete environmental safety, is resistant to all external types of impact, has excellent thermal insulation properties and moisture resistance. The only drawback of this type of filler is flammability.
  4. Expanded polystyrene - sandwich panels with this heat-insulating layer are often used in the construction of commercial establishments, arrangement of refrigerated chambers.

    The material has a porous structure, and this ensures the reliability of the insulation of the interior. But expanded polystyrene has a relatively low degree of strength, and this negatively affects its durability.

Here are the comparative characteristics of panels with different types of insulation.

If you know these features, it will not be difficult to choose sandwich panels according to your individual type requests.

Weight

We will consider the dimensions of roofing sandwich panels, now it's worth talking about the mass.

The structural weight of the panels will directly depend on the thickness and type of thermal insulation layer. Moreover, the insulation density also plays a key role. For example, for mineral wool, this figure is 110 kg per square meter, for foam, 25 kg per square meter. Accordingly, subject to standard typical dimensions, the weight of panels for walls with mineral wool can be from 16 to 39 kg. Similar products, where foam is used as a heater, will weigh from 12 to 17 kg.
