| DuPontTM Tyvek® Soft – one-layer breathing diffusive membrane meant for walls and roof. The product of exclusive characteristics is received thanks to the unique production technology of high level. It is completely impermeable to wind and water, but it also has high characteristics of vapor permeability. The Tyvek® products have an exceptionally thick functional layer, which makes the product durable and lasting. The membrane is laid directly on the heating material without leaving any additional gap for air. We recommend: To glue the membrane‘s junctions with Tyvek adhesive tape. Only the solid construction will be especially impermeable to wind and water.
