Engineered to provide protection to buildings and their occupants from external climatic conditions and from the effects of condensation.
Highly water resistant and lightweight (61g/m2) vapour permeable membrane suitable for use as the secondary protection layer in timber frame, steel frame and concrete wall systems. Membrane should be surface applied, fixed directly to ply/OSB sheathing board, insulation or blockwork.
The DuPont™ Tyvek® family of membranes have been developed by DuPont™ to provide protection against the hazards associated with the construction and use of buildings; the principle hazards are:
- Climatic conditions - rain snow, hail, wind, ground moisture
- Condensation - occurring on and within the building fabric
Tyvek® membranes are engineered for the purposes of providing protection to buildings and their occupants from external climatic conditions and from the effects of condensation. By controlling the movements of heat, air and moisture through the building envelope, Tyvek® membranes can make a major contribution to protecting the environment by improving the energy efficiency of buildings.
To achieve the required internal conditions with optimum efficiency it is essential to consider air flow and moisture movement together with all aspects of heat transfer, not only by conduction, but also by convection and radiation. The reduction of air leakage, the avoidance of damaging condensation and the provision of thermal insulation must all be considered together to ensure the protection and well-being of the occupants and the long term protection of the building fabric.
