Product Description

The Earthwool® glasswool insulation: wall batt range includes a selection of R-values and densities to provide builders, designers, installers and DIYers the opportunity to choose the best thermal and acoustic performance for their  project. Earthwool® glasswool insulation: wall batt will absorb the transfer of unwanted sound from outside to inside the building. In addition to sound absorption, Earthwool® glasswool insulation: wall 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 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.
