Product Description

The Earthwool^® glasswool insulation: ceiling batt range includes a selection of R-values to provide builders, designers, installers and DIYers the opportunity to choose the best thermal performance for their project. Earthwool^® glasswool insulation: ceiling 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^® glasswool have been further enhanced with TwinTech^®. TwinTech^® heralds another advancement in 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 insulation: ceiling batt 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^® glasswool insulation is silicone treated, which provides moisture resistance for up to 50 years.
