Mineral Wool Boards Gecsatherm® VPG34

Product Description – Gecsatherm® VPG34 semi-rigid mineral wool boards 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 – Gecsatherm® VPG34 semi-rigid mineral wool boards are used for all types of thermal and sound insulation subjected to low mechanical loads, between ceilings, wooden beams, non-rolling tiles, suspended ceilings. Due to the special structure of the fibers and their distribution, they behave very well in the vertical insulation which recommends them for the thermal and sound insulation of the partition walls, exterior walls, ventilated facades, inclined roofs, attics.

     With a solid and homogeneous structure, the Gecsatherm® VPG34 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.
