Product Description

Earthwool® quilted underfloor batt is manufactured from durable silicone coated glasswool and is completely wrapped in a breathable plastic film, providing a wind-wash barrier. The wind-wash barrier provides protection from wind travelling through the floor. Adding to the already easy to handle and install qualities of Earthwool® insulation, the plastic film allows for the insulation to be stapled in place.

Earthwool® quilted underfloor batt will improve the thermal comfort and energy efficiency of the building in which it has been installed thus keeping it cool in summer and warm in winter. Earthwool® insulation is made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.
