Overview

LOTFIX F30 Low Expansion Door Window PU Foam is a one-component polyurethane foam developed for window and door installation where more controlled expansion is important. It is suitable for filling and sealing around frames, connection gaps, and common openings while helping create a cleaner and more balanced installation result.

Designed for both gun type and manual type application, F30 is especially suitable for projects that need a foam focused on frame installation rather than simple high-volume filling. When applied correctly, it helps support stable positioning around windows and doors and reduces the risk of bowing or warping during installation.
