DuPont Performance Building Solutions

DuPont is a science based company operating in over 70 countries. DuPont developed Tyvek® 50 years ago, and has more than 30 years’ experience in the construction market with more than 15 million buildings protected with Tyvek® membranes. DuPont™ Tyvek® is the world’s largest manufacturer of breather membranes and is one of the leading brands in the UK.

DuPont™ Tyvek® protects buildings and occupants, while at the same time protecting the environment, by helping to control the movement of heat, air and moisture through the building envelope. Tyvek® roofs and walls are extremely efficient, cutting energy consumption, heating bills and greenhouse gas emissions thus reducing the risk of global warming.

New additions to the DuPont™ Tyvek® family are:

– Tyvek® FireCurb® Breather Membrane, a unique, flame retardant membrane, applied to the external face of the timber frame, SIP or cladding system, as the critical second line of defence. Rated as W1 for water resistance, Tyvek® FireCurb® may be used in all exposure zones, without restriction.

– Tyvek® Trifecta(TM) W1 Breather membrane is A2 rated (to EN 13501) when used with non combustible sheathing and insulation.

– DuPont™ Airguard A2FR is a EN13501-1 A rated AVCL for use in all building types, regardless of use and at any building height.
