Product Description

Knauf Insulation Climacoustic Ductwrap (faced) with ECOSE® Technology is used as external insulation on commercial or residential heating or air conditioning ducts. It is suitable for the exterior of rectangular or round sheet metal ducts and spaces or surfaces where  temperature and condensation must be controlled. Knauf Insulation Climacoustic Ductwrap (faced) is made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.

The super-soft and easy to handle benefits of Climacoustic insulation 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.
