The 2-ply material has a vapor permeable dispersion layer on top of a highly tear-resistant special PET fabric to make it both extremely durable and water resistant.
This tough membrane has an extremely high water vapor permeability, which ensures excess moisture never seeps under the roof. A water-repellent dispersion coating makes DELTA®-FOXX permanently and reliably waterproof.
DELTA®-FOXX is very easy to handle and lay down. The lightweight rolls enable quick unrolling and precise alignment of edges. The smooth underside allows for DELTA ®FOXX to be effortlessly pulled over rough surfaces. This highly scuff and tear-resistant membrane allows you to safely walk onto of it when laid on top of solid sheathing. This superior roofing membrane can be walked on in rain or shine.
