Product Description

Earthwool® glasswool insulation: multi-use roll is available in energy efficient R-values to provide an ideal solution for topping up existing ceiling insulation or for providing high thermal performance in walls. Earthwool® glasswool insulation: multi-use roll 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.
