Can cassettes be used in constructions with increased requirements for acoustic attenuation?
Yes. In case of specific requirements for acoustic attenuation, it is possible to supply cassettes with perforation. Such modification allows the attenuation of sound waves in the insulation layer, which significantly improves the acoustic parameters of cassette walls.
What advantages does the use of cassette walls bring from the viewpoint of cladding?
Especially a very favourable price/quality ratio. Also quick installation, a high variability of external cladding, good fire resistance and thermal parameters, a long lifetime and minimum maintenance requirements.
What fire resistance parameters can Satjam cassette walls achieve?
The company Satjam has tested fire resistance in three types of cassette walls which differed in the insulating material used and in the type of external cladding. Specific results are available on the internet and they are much higher than the standard of competing products.
How do the parameters of cassette walls compare with the parameters of sandwich panels?
Cassettes are a direct competitor to sandwich panels. Therefore, their parameters are comparable. Cassettes are usually insulated with mineral wool and therefore they have better fire resistance as compared with sandwich panels which usually use polystyrene or polyurethane for insulation. If preset insulation is used in cassettes, thermal bridges are removed very easily. There is also a broader variability of external cladding – it is possible to use common trapezoidal sheets in a vertical or in horizontal direction, or to use any arbitrary type of facade profile.
In what way are the cassettes fixed to the steel and concrete columns?
Steel: By means of self-tapping screws with a tapping capacity corresponding to the thickness of the steel element to which they are attached, or by means of a nailing gun. Concrete: By means of special screws, or by means of a nailing gun.
