Product Description

The Knauf Insulation acoustic batt range includes a selection of densities to provide builders, designers, installers and DIYers the opportunity to choose the best acoustic performance for their project. Knauf Insulation acoustic batt will improve the acoustic performance of the building in which it has been installed by absorbing the transfer of unwanted sound from external sources and between adjoining rooms.

The super-soft and easy to handle benefits of Knauf Insulation 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. Knauf Insulation 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. Knauf Insulation glasswool is silicone treated, which provides moisture resistance for up to 50 years.
