A non-combustible class A1 inverted roof insulation.
FOAMGLAS® INVATHERMᵀᴹ has been engineered to meet the demand for a class A1 inverted roof insulation board for use on roofs, roof terraces and balconies. Suitable for use with any inverted roof waterproofing membrane including hot melt, liquid applied, reinforced bitumen membrane or single ply membrane.
Consisting of cellular glass with a pre-applied inorganic coating on the topside both the core material Foamglas® InvaThermᵀᴹ is manufactured from specially graded recycled glass (≥60%) and natural raw materials which are available in abundant supply (sand, dolomite, lime). Totally inorganic Foamglas® InvaThermᵀᴹ contains no ozone depleting propellants, flame resistant additives or binders, VOC or other volatile substances.
