Mineral Wool boards faced with aluminium Gecsatherm® VPG 34 ALU

Product Description – Gecsatherm® VPG34 ALU semi-rigid mineral wool boards faced with aluminium are made of inorganic mineral fibers linked together with polymerized resin to form a homogeneous mattress, with special mechanical properties due to the special fiber distribution system and binder.

Aplications – It is used for the thermal and sound insulation of the exterior walls, the attics, the interior floor sills, (garages, basements, etc.). They are mounted with the aluminium face inwards, in order to increase the efficiency of the thermal insulation and to obtain the thermal effect. In addition to the role of reflecting heat radiation back into the living space, aluminum also constitutes a vapor barrier that limits the migration of vapors from the heated interior. At the garage or basement ceiling, the plates should be fastened with metal rosettes. When installing the insulation, special attention will be paid to the sealing of the spaces between the cotton mattresses. For this operation, the aluminum self-adhesive tape, specially intended for this purpose, will be used.

     With a solid and homogeneous structure, the Gecsatherm® VPG34 ALU semi-rigid mineral wool boards will not break down and will not change in time, they provide excellent sound insulation due to the fibrous structure of the material, they are very easy to handle and install.
