These boards are specifically designed for the thermal and acoustic insulation of pitched roofs with regular as well as irregular roof joinery. For easy cutting, the boards are provided with cutting marks every 10 cm.

Korafleece roof underlay is the ideal choice for a reliable roof underlay. The membrane is highly vapour permeable and has ideal ageing properties. High vapour permeability: Sd value of 0.03 m, allowing the underlay to be laid directly on top of the insulation. With integrated double adhesive tape for a perfectly windtight finish. High tensile strength.
