Thermafleece Supasoft Insulation is an innovative solution crafted from recycled polyester, with a substantial portion derived from recycled plastic bottles. Polyester fleece is a superior insulation material, widely recognised for its effectiveness in filling in ski jackets and duvets. With a Thermal conductivity of 0.04 W/mK, Supasoft surpasses standard fibreglass or mineral wool insulations, offering enhanced thermal performance and a super-soft and safe-to-handle experience*.

Key Features:

Durable: SupaSoft insulation incorporates a lofting agent to ensure lasting durability and is designed to endure the lifespan of the building in which it is installed.

Breathable: As an open, non-woven material, SupaSoft insulation allows water vapour to pass through, contributing to a breathable and healthy environment within the building.

Recyclable: Composed of 100% Polyester, with more than 95% recycled material, Supasoft is an environmentally conscious choice. It is also recyclable, aligning with sustainable practices.
