Glass Wool Gecsatherm® VSG 37

Product Description -GecsaTherm® VSG37 glass mineral wool rolls are made of inorganic glass fibers bonded together with polymerized resin to form a smooth, light and flexible mattress.
The glass fibers are obtained by melting at over 1500 OC of the mineral raw materials, especially quartz, fibrilization by the “off-center” technology, then by spraying the binder for sealing and oils for waterproofing are added.

AplicationsGecsaTherm® VSG37 glass mineral wool mattresses can be used for all types of thermal or sound insulation without mechanical loads, such as sloping roofs, as fillings between ceilings, suspended ceilings, interior and exterior walls, non-rolling floors.
