We are drying in the roof with DuPont Tyvek breathable membrane.

Tyvek Weatherisation Systems make homes and more comfortable and more energy efficient and protect them from water damage. Tyvek can help protect against air infiltration and manages moisture vapor.

Because the whole roof is now a vent there is less likelihood of condensation and damp in your roof space.

With Tyvek you can do without the rest of your roof ventilation.

DuPont analyzed our roof and did a report showing how Tyvek will perform based on ou roof design and size and generated a report for the building inspectors.
