Product Description

Earthwool® glasswool insulation: 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 air movement under the floor. Adding to the already easy to handle and install qualities of Earthwool® glasswool insulation, the plastic film allows for the insulation to be stapled in place. Earthwool® glasswool insulation: 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® glasswool insulation made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.
