Everyone knows what a sandwich panel. And that's what the sandwich-panel-element assembly? The design of this type consists of a base – the cassette profile in which to insert insulation (mineral wool or any other) Further attached windproof barrier, and then – outer surface of the wall (lining). As the liner is usually used corrugated board with a polymer coating, metal siding and front panel. The basis of 'team' sandwich panels – cassette profile. The depth profile of the cassette, respectively, the thickness of insulation is chosen, which will be incorporated into it (usually from 100 to 200 mm).
The thickness of the insulation depends on the quality of applied insulating material and the requirements for . What are the advantages of sandwich panels based on the cluster profile compared to conventional sandwich panels? They are: Best fire safety. In the facade designs Cassette profile forms a honeycomb structure, which, unlike the usual sandwiches, makes the spread of fire inside the wall. Less weight. The most common 'glued' sandwich panel filler – mineral wool with a density of not less than 100 kg / cubic meter. It is easy to calculate that, at the thickness of the sandwich 200 mm Weight per square meter will be no less than 34 kg.
For sandwich panels-element assembly may be used easier filler lower specific gravity. This helps reduce the weight per square meter in almost half (for example, if we use a filler density of 40 kg / cubic meter). The possibility of a less dense filler (and thus – with lower thermal conductivity) provides another positive effect – the higher insulating properties with an equal thickness of sandwich panels.
