This building material is very limited in additional load: the load will be calculated at the stage of building design
Sometimes sandwich panels can be subject to minor mechanical damage. This also requires increased attention to sealing. It is recommended to use sandwich panels, which will be filled with basalt or glass fiber. These materials are non-flammable.
Of course, it is impossible to build buildings with bizarre architectural elements from such a building material: more expensive materials exist for this purpose. Particular attention should be paid to the ventilation system, which should be thought out in advance, otherwise it may be uncomfortable to be in the building.
More about sandwich panel fillers
There are a few basic materials in total. The first of which will be basalt fiber mineral wool. Such wool, in turn, can be of several types: glass wool, which is made from molten glass, stone wool based on molten rocks and silk wool, the basis of which is blast-furnace slag.
Basalt wool can be made from several rocks that are similar in chemical composition. These rocks include basanite, basalt, gabrodiabase, amphibolite, and their mixtures. Such fiber can be of two types: staple and continuous. These two types will differ in fiber diameter; in fact, this indicator will affect many characteristics of the future building.
Many summer residents prefer basalt fiber, which has a high degree of sound insulation and is completely not subject to combustion.
Mineral wool made from fiberglass is also non-combustible and sound-absorbing material. In addition, this material is very durable and resilient. All these qualities are achieved precisely due to the length of the fiber: for glass wool this indicator is five centimeters, and for basalt fiber it is one and a half centimeters. However, any type of mineral wool has a low degree of resistance to moisture and a significantly higher weight.
Insulating material such as expanded polystyrene is also quite popular. The main distinguishing features of this material: light weight, environmental friendliness and durability. Based on the modification, this filler can be either flame retardant or self-extinguishing.
Such material as polyurethane foam is also quite common. In this case, the properties of thermal insulation will be significantly increased, this circumstance also applies to the properties of waterproofing. This filler is also hardly flammable, and is also resistant to both biological and chemical factors. However, such structures will have a small thickness, but at the same time they will be lighter and much more durable than other options for sandwich panels.
The choice of sandwich panel filler should directly depend on the basic requirements for the future construction.
Based on the external profile, several types of sandwich panels should be distinguished: smooth or corrugated on both sides, profiled on one side, as well as decorative profiled: log or siding.
Roof panels that are smooth on both sides are most often used to provide additional insulation to the roof. Shirring can also take on decorative functions. The main development of wall and roof panels is in the system of locks and stiffness parameters. This circumstance is due to the various loads that fall on the roof and walls.
Selecting a specific type of sandwich panels should also take into account the specific requirements for each building.

These sheets will not burn in air. Most often, such sandwich panels are used indoors. This is due to the fact that PVC sheets are characterized by low resistance to frost and these sheets will be highly susceptible to mechanical damage
