Where to use

Perimeters, chimneys and abutments, also for sealing nail penetrations and around electrical sockets: Tyvek Butyl Tape is used to create a secure, watertight seal in areas that are prone to moisture ingress. It is commonly applied in the following situations:

  • Around windows and doors to seal gaps between the frame and building structure.
  • At overlaps between membranes, particularly where additional waterproofing is required.
  • Penetrations through the building envelope, such as pipework, cables, or ducts.
  • Along roof edges, valleys, and joints to prevent water from seeping through the roofing membrane.

Its strong adhesion and flexibility make it ideal for sealing around difficult or uneven surfaces in both roofing and facade applications.
