DuPont™ Window & Door Foam is a minimal expansion, low pressure polyurethane foam, which works with DuPont™ Tyvek® Weatherization Systems products, to create a protective barrier that may contribute to increased energy efficiency; reduced heating and cooling costs; and protection against moisture infiltration that could lead to the formation of damaging mold and mildew in wall structures.

Recommended uses:

Window and door installation
Electrical and plumbing penetrations
Mudsills
Jambs
Header joints
Top plate penetrations

Features & Benefits:

Low foam pressure, low expansion
Less waste, little or no trimming
Quick setting formula
No mixing
Closed cell foam structure
Excellent insulator

How It Works:

DuPont™ Window & Door Foam is easy to use and scientifically proven to work with the complete line of DuPont™ Tyvek® Weatherization Systems products. This foam is used in conjunction with an applicator gun, and it is dispensed in bead form for sealing gaps, cracks, holes and voids around windows and doors, in most types of construction projects. Slight to moderate expansion is exhibited during application, and upon reaction with moisture, it cures to form a flexible, urethane foam. The closed cell structure of this material provides an R-Value of 5 per inch of cured foam, making it an efficient method for stopping air and moisture infiltration and expensive warm and cold air loss between windows and rough frames. This low pressure foam will not warp or deform windows and doors. It adheres to all types of building materials including wood, concrete and drywall, and it is compatible with asphalt and butyl flexible flashing.
