About DuPont™ A subsidiary of US-based $27 billion E. I. du Pont de Nemours and Company, a 204-year youngscience and technology company and one of the oldest industrial enterprises in the world. Founded in 1802 in Wilmington, Delaware, USA, DuPont delivers science-based solutions for markets that make a difference in people's lives. Today we operate in more than 70 countries worldwide. Why Tyvek®? For over 40 years Tyvek® breather membranes have offered a leading global solution for the protection of buildings from climatic conditions and the effects of condensation. As an underlay DuPont™ Tyvek® acts like awindbreaker; it resists to wind- and air infiltration, as well as water intrusion and helps to create a more comfortable, and energy-efficient building. DuPont™ Tyvek® Weatherization ( Insulation ) System for Pre-engineered buildings & Industrial roofs. DuPont™ Tyvek® Subtex is two component system that combines the insulation wool blanket with theTyvek® Solid vapour breathable membrane. The unique insulation blanket has high thermal and acoustic properties, unlike glass wool, it does not absorb moisture, and is safe to handle. Tyvek® Solid membrane helps prevent condensation and allows incidental moisture ingress to breathe out.
The insulation blanket, at 8 kg/m2 is light andeasy to handle. Higher densities may be made available on request. DuPont™ Tyvek® Weatherization Systems comprise a vapour- breathable, tough and durable membrane manufactured from spun-bonded polyolefin. This membrane keeps insulation dry and performing effectively for a long time by minimizing condensation and othermoisture-related problems. The system also includes Tyvek® Subtex, a unique moisture resistant and light-weight insulation blanket with a breathable Tyvek® substrate. Tyvek ® Subtex has been especially designed for acoustic & thermal insulation in pre-engineered buildings and industrial roofs. Superior Properties of DuPont™ Tyvek® Subtex – Roof ( Poly Wool ) Insulation * Light weights and easy to install. * The substrate and the blanket of DuPont™ Tyvek® Subtex are inert materials in case of contact with water.
* The contact of the product with the skin does not represent any risk in normal condition of use. * Tyvek® Reflex reflects radiant heat, allows water vapor to pass through for drying of insulation in case of water infiltration or interstitial condensation. * Has low thermal conductivity. * The system is breathable, allowing moisture to escape while looking out water and air, in turn helping create a controlled space for industrial use. * The substrate i.e. Tyvek® Reflex has high tear strength, it does not tear easily during installation as the case may be in Aluminum foil substrate.
