ProTherm FOAMGLAS® INVATHERM™ - Class A1 Inverted Roof Insulation
Verified by manufacturer 4 months ago
A non-combustible class A1 inverted roof insulation.
Application
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.
Description
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.
Features and benefits:
- Class A1 to BS EN 13501-1 (non-combustible).
- High compressive strength.
- Dimensionally stable.
- Impervious to water vapour.
- Acid and chemical resistant.
- Resistant to attack.
- Proven thermal performance.
- Ecological.
- No toxic fumes.
- Classified A1 to BS EN 13501-1 by Warringtonfire under reaction to fire classification report No. 19984E.
- Delivery form: Shrunk wrapped on a pallet, quantity depending on board thickness.
- Storage and transport: During shipment, storage and installation handle with care so as to avoid physical damage.
