Ultracoustic Plus Kraft

Knauf Ultracoustic Plus Kraft is a roll-form glass mineral wool product, coated on one side with kraft paper. It improves the thermal and acoustic insulation of building envelopes, while its coating helps limit the passage of water vapor and reduce the risk of condensation.

It is primarily intended for interior cladding of facades, sloped roofs, suspended ceilings, and building envelopes where a vapor barrier is required. The coated side must face the heated interior space, following the instructions for the construction system.

It has a thermal conductivity of 0.035 W/(m·K) and a flexible format that facilitates cutting, transport, and installation. It incorporates a plant-based binder, with no added formaldehyde or phenols, and contributes to indoor comfort and energy efficiency.
