Polyurethane installation foams are one-component or two-component products used in the construction industry for gap filling, thermal and acoustic insulation, installation support, and the creation of airtight seals. These moisture-curing systems expand upon application, filling cavities to provide both insulation and effective gap sealing.
Today, installation foams are used not only for window and door installation but also for service penetrations, prefabricated building components, roofing applications, and a wide range of insulation details. Their controlled expansion allows them to adapt to irregular cavity geometries, and once cured, they can be easily trimmed and shaped as required.
The primary function of installation foam is not to provide structural load-bearing capacity, but to fill installation gaps, reduce thermal bridging, and limit air leakage. Therefore, in applications requiring structural support, installation foams should always be used in combination with appropriate mechanical fastening systems.
Typical applications include:
Window and door frame installation
Perimeter gaps around window and door frames
Wall and floor penetrations
Roof details
HVAC service penetrations
Electrical and mechanical service openings
Prefabricated building joints
Lightweight partition wall systems
Gaps requiring thermal and acoustic insulation.
Technologies Used
Polyurethane Assembly Foams
One-component polyurethane foams cure by reacting with atmospheric moisture and represent the most widely used installation foam technology in the construction industry.
Depending on the application method, they are available as gun-grade foams and straw-applied (manual) foams.
For professional applications, gun-grade systems are preferred because they provide more precise dispensing, better application control, and reduced material waste.
Fire-Rated Polyurethane Foams
These specially formulated polyurethane foams are designed for construction details where fire resistance is required.
When used as part of tested firestop systems, they help maintain the fire compartmentation performance of the building.
