Earthwool® glasswool FloorShield underfloor batt is manufactured from durable silicone coated glasswool and is faced with an ECOSE® glass veil, providing a wind-wash barrier. The wind-wash barrier provides protection from air movement under the floor to ensure the insulation will perform as per the stated the R-value*.

Earthwool glasswool FloorShield 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.

The super-soft and easy to handle benefits of Earthwool have been further enhanced with TwinTech®. TwinTech heralds another advancement insulation manufacture — the dual forming technique ensures there is a smooth finish on both sides of the insulation, which improves product handling and appearance. Earthwool glasswool is made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.

Enhanced moisture resistance with DriTherm® technology. Earthwool insulation is silicone treated, which provides moisture resistance for 50 years.

*BRANZ research has shown the impact of wind-wash on exposed sub-floor insulation can reduce the thermal performance by 25%, see Build Magazine article.
