The original nonwoven technology.
Since the initial discovery in 1955 that led to Tyvek®, DuPont has been a recognized global leader in selective barrier technology. Lightweight and durable, DuPont™ Tyvek® has introduced new dimensions of protection, security and safety in a wide variety of industries.
With more than 30 years of performance in millions of homes all over the world, DuPont™ Tyvek® high-performance protective membranes offer leading solutions for the protection and energy efficiency of the buildings.
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 a windbreaker; it resists to wind- and air infiltration, as well as water intrusion and helps to create a more comfortable, and energy-efficient building.
Minimises air and water ingress, whilst allowing moisture to migrate freely and safely into the atmosphere as required in Building Regulations/Standards(Tyvek® high vapour permeability). Helps minimise condensation to protect the building structure, preserve the integrity of the insulation material and thus its performance and provides a healthy indoor climate.
Helps to reduce energy loss due to uncontrolled air infiltration (Tyvek® air tightness). The new generation of metallised membranes reflect the heat inside the building during winter leading to increased energy savings (Tyvek® low emissivity). Helps to minimize CO2 emissions by reducing energy consumption.
Tyvek® membranes control the movement of heat, air and moisture in a building by minimising air leakage and therefore allowing greater environmental control to the occupants. The new generation of metallised membranes helps to reflect external heat during the summer.
Tyvek® membranes help to satisfy items a, b & c of Approved Document C(2) for England & Wales and Sections 3.10 and 3.15.4 of The Scottish Building Standards – Resistance to moisture/Precipitation and Interstitial condensation. Tyvek® membranes also assist in satisfying Approved Document L for England & Wales and Section 6.2.5 of the Scottish Building Standards – Air permeability/Air infiltration. Tyvek® metallised membranes further assist in Part L and Section 6.2 compliance by improving thermal performance.
