Fischer One-Component Gun Foam for Insulation & Sealing

Designed for professional insulation and sealing tasks, the Fischer one-component gun foam offers reliable performance for a wide range of construction applications. Formulated as a one-component polyurethane (PU) foam, it expands and cures to create a durable, airtight barrier that enhances thermal efficiency and acoustic comfort in residential and commercial buildings.

This product is specifically engineered for use with a standard foam gun, allowing for precise dosing and control during application. The compact can design ensures high foam yield, maximizing coverage per unit and reducing material waste. A key practical advantage is its user-friendly workflow: during longer breaks, the can can remain unscrewed from the gun, allowing the user to simply resume work without losing the remaining product or requiring complex re-priming.

The foam is ideal for gap-filling around window and door frames, sealing joints in drywall construction, insulating roof penetrations, and securing façade insulation systems. For maintenance, fresh foam residue can be easily removed using Fischer PU-cleaner, ensuring tools remain clean and ready for the next task.
