JUTADACH roof underlays are manufactured by thermally bonding two layers of non-woven spun bonded polypropylene with a microporous film to create a weatherproof breathable membrane.
In pitched roof construction JUTADACH underlays are suitable for both supported and unsupported use and for roofs with or without sarking boards. JUTADACH can be laid directly over thermal insulation with no requirement for ventilation space from bottom side, meaning that the full height of the rafters can be used for insulation.
JUTADACH underlays are available in different weight according to the marking. They are always durable and combine corresponding water-resistance with high vapour permeability, making them very versatile and suited to a wide range of applications. JUTADACH offer year round protection in all weather conditions against leakages and water vapour condensation.

JUTADACH underlays can be tailored to your requirements in regards to colour, design and palletisation.
