Unique technology is used to create the fibre structure of Tyvek®. Backed by more than 30 years experience worldwide it ensures superior durability and long term performance which provides the following benefits:
Tyvek® is the only product with a unique functional layer that is entirely made up of millions of unique micro fibres. These are bonded together to create a maze that stops water penetrating, whilst allowing water vapour to freely move through the fibres (pores).
Moisture management and protection from the external elements
- 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.
Energy efficiency
- 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.
Comfort
- 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.
Building regulations compliance
- 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.
Technical support
Experts available to offer detailed technical assistance and advice as well as U-value and condensation risk calculations (ask for a condensation risk analysis form).
