Origin: France aeronautics
Composition: panels sandwich made of felt, sheep wool, plastic sheets, etc.. enclosed between two sheets of aluminum
Thickness: 1.2 cm still around
Uses: Walls, floors, pitched roofs, etc..
type of installation: for now should only be used for insulation from the inside. Must be placed between two hollow air-tight (to prevent drafts, dust deposition on the faces of the panel, etc..) About 2 cm. The trimming may be of any type (plaster, against the, etc.).
Insulating power: it is not CE, have not been tested in accordance with the legislation in place for traditional materials ... Some manufacturers declare them equivalent to 21 cm rock wool, but without providing any type of CE marking for the product ... According to some European institutions however, are treated as a normal polystyrene plus a performance by 30% due to the effective reflectivity of the material ....
Power Sound: virtually nil, it should be "helped" with something more suitable
Highs:
- relatively low cost (on the third € / sqm laid)
- Added the list of usable materials Casaclima (!?)
Defects :
- There are CE and then those who sell such material does not provide any certification "serious" that guarantees the performance of the material
- From acoustically is poor
- Needed a pose accurate (provided, however, essential for any insulation)
- should be protected against moisture
Conclusions:
material that is sold as the panacea of \u200b\u200ball evil ... in fact in Germany, for a known company that has been forbidden to advertise its drug materials with the values \u200b\u200bgiven in their brochure ... values, which would be easily "sold" in Italy without any problems ...
