Airtightness Installation Guide

Why is airtightness so important? 

As we progress into the future with more energy efficient and sustainable building methods we are becoming more aware of the shortcomings, environmental impact and costs of uncontrolled air leakage.

The requirements and regulations on the energy performance of buildings continue to increase. Because of air leakage from the building envelope, heat losses through convection can occur. Choosing the right air and vapour control layer (AVCL), breather membrane, tapes and accessories will help create a thermally efficient, condensation-free structure.

Installing one of the DuPont™ AirGuard^® AVCL membranes will keep your insulation and wall structure dry and can help to reduce energy consumption. On top of choosing the right AVCL it is important to make your building envelope airtight and windtight by sealing gaps between and around insulation layers, AVCL’s and breather membranes. With DuPont accessories you can choose the right products to complement and enhance DuPont™ Tyvek^® building envelope solutions. The adhesive tapes are specially designed for use with DuPont membranes to help reduce or even avoid uncontrolled air leakage.
