Comfort of the wooden house is now possible in the attic: DuPont offers new breathable house concept. Multi layer roofing system securing comfortable climate in ensured by the three key elements:

- New Tyvek® Supro breather hydro insulation membrane,
- Tyvek® VCL breathable vapour barrier,
- Fibre thermal insulation (standard roofing solution).

Tyvek® Supro is a highly durable innovative material. Tyvek® Supro has a number of unique properties: extraordinary strength, excellent vapour permeation and durability (its service life amounts to over 50 years). The adhesive strip of Tyvek® Supro membrane allows easy mounting and helps avoid many inaccuracies and mistakes during installation. The sealed overlaps of the Tyvek® membrane ensure maximum protection from heat losses and outside moisture.

Another important material for breather attic construction besides high quality hydro insulation Tyvek® Supro membrane is Tyvek® VCL – ultra advanced breathable vapour barrier. Unlike conventional vapour barriers, Tyvek® VCL transmits a small amount of vapour, eliminating the greenhouse effect and protecting the attic from the excessive humidity. The thoroughly balanced vapour permeation properties of whole roofing system: Tyvek® Supro hydro insulation membrane, heat insulation and Tyvek® VCL vapour barrier – prevent moisture and vapour from being caught in the insulation and help them successfully pass through the construction into ventilated room.

Breathable house designed with the help of the most advanced DuPont technologies ensures the temperature and moist balance, similar to that of a pure wooden construction. DuPont innovative technologies – Tyvek® Supro hydro insulation membrane and Tyvek® VCL vapour barrier – create comfortable and healthy climate. They protect the building, guarantee residents’ comfort and meet European Union safety and environmental standards.
Vapour permeable Tyvek® membranes have secured their position on the Russian market; they are manufactured at DuPont plant in Luxembourg through application of the unique production technology.
