Description

Keep your home airtight and energy-efficient with SFM Rapide 500ml Gap Expanding Foam Filler. This PU expansion foam expands on contact, sealing roof tile voids, draught points and any opening around pipe entries, windows and doors. The fast-curing formula creates a strong bond that holds insulation in place, reducing heat loss and keeping out drafts. Use it before plastering to protect electrical wiring runs, or fill deep joints so sealants adhere better and last longer. It works equally well on wall cracks and floorboard gaps, providing a durable, flexible seal that moves with the structure. The 500ml can delivers plenty of material for multiple projects, yet remains easy to control for precise application in tight spaces. Whether you are a DIY enthusiast or a professional tradesperson, this foam filler simplifies preparation work and improves the final finish of any renovation or new construction. It also resists moisture and remains stable over time, giving you lasting protection for years to come.

Key Features

Expands quickly to fill roof tile voids and draught points, creating an airtight seal that improves energy efficiency and reduces heating costs.

Forms a strong PU bond around pipe entries, window and door frames, preventing air leaks and keeping insects and dust out of your living space.

Ideal for electrical wire chasing before plastering; the foam expands without damaging cables and provides a protective cushion for safe, clean installations.

Fills deep joints and cracks in walls and floorboards, delivering a flexible yet durable seal that moves with the structure and supports subsequent sealant or plaster.

500ml can provides ample material for multiple projects while remaining easy to control, allowing precise application in tight spaces for professional-grade results.
