Sealing Gaps and Cracks

Building construction involves many transitions between materials and systems. At each of these transitions, gaps are provided to allow for movements between materials. One component foam sealant, also known as foam sealant or foam-in-a-can, can be an ideal product for sealing gaps and cracks around windows, doors, and other penetrations.

One component foam sealant bonds readily to wood, masonry, metal, glass and many plastics. It sets and cures quickly, hardening into a protective shield that helps prevent air from crossing the foam barrier where it is installed.

Typical applications for single component foam sealant include:

•  Filling gaps and cracks around window and doorframes
•  Closing gaps around outside-wall penetrations made by gas lines, water pipes or dryer-vent hoses
•  Filling gaps inside the home caused by electrical line or HVAC vent penetrations
