Blanket Insulation | Polyair Multi

Supplier: Polyair

Polyair Multi has been designed and engineered specifically around the latest thermal requirements of the Building Code of Australia.


Polyair Multi delivers high R-Values, practical compliance solutions, thermal break performance, durability and substantial cost savings in construction.

The advanced manufacturing techniques combine a multi layered inner core composition of cross linked XPE fire retardant foam with a double layer of fire retardant polyethylene bubble film. The inner core layers are enclosed with two external thermal reflective layers of pure aluminium foils with one surface coated in a special highly reflective copper anti glare coating.

Polyair Multi excels in laboratory testing for all mandatory Australian Standards and Building Code of Australia certification benchmarks. Polyair products are engineered to comply with the ABGR and Green Star Rating Scheme and avoid the use of ozone depleting substances in both manufacture and composition.
