When it comes to building more energy efficient homes or commercial buildings you can count on DuPont™ Tyvek® and DuPont™ AirGuard®. These innovative building products can have a positive impact in three key ways:

• protecting against bulk water intrusion and air-transported moisture
• reducing air infiltration through roof or wall cavities
• reducing air leakage by sealing the building envelope to make the inside of your house airtight

Choosing DuPont™ Tyvek® construction products can help you meet requirements of Part L in England and Wales and of Scottish Technical Standard 6.

Sealing the building envelope inside and outside

The energy efficiency of building can be significantly improved by making the inside airtight and vapour resistant. 

Vapour control layers suitable for roofs, walls and floors help to reduce convective heat losses but also provide highly engineered vapour control for breathing systems. When installed continuously with all laps and penetrations sealed, a vapour control layer will provide effective condensation control for all building types.

The DuPont range of accessories has been developed to compliment and enhance building envelope solutions with Tyvek®. It helps to reduce uncontrolled air leakage through the building envelope and reduces ventilation heat losses.
