Pink® Batts® and DuPont™ Tyvek® coming together for greater good
Before 1980 building underlays did not exist as we know it. DuPont™ created a synthetic product that could be cut but not torn, and which allowed moisture vapour to pass through but nothing else. Tyvek® was born and after 30 years of category leadership and millions of installations, DuPont™ Tyvek® is still the builder’s choice in the weather tightness system throughout the U.S.A.
The Pink® Batts® insulation team is now partnering with DuPont™ to distribute Tyvek® building envelope solutions in New Zealand. We believe our partnership will bring together proven product quality, experience and a no-nonsense service promise you can rely on.
Tyvek® is manufactured and supplied by DuPont™ Australia Pty Ltd to Tasman as authorised NZ distributor. Information about Tyvek® products has been provided by DuPont™/Tyvek®.
DuPont™ Tyvek® building envelope solutions provide a balance of four properties to maintain the protection, comfort and efficiency of the building:
Air resistance to help prevent the flow of air through cavities and reduce drafts
Moisture resistance to help protect against water
Moisture vapour permeability to promote drying
Durability to withstand rigours of the construction process
Defining the difference
DuPont™ Tyvek® is made from single-layer high-density polyethylene composed of millions of microfibres spun-bound in a maze-like structure. The structure and patented technology of the Tyvek® membrane provides
excellent resistance to UV with a comfortable 120-day exposure limit
temperature resistance up to 100°C
