Description

Soudal Professional Gap Filler – The Ultimate Expanding Insulation Solution

The Soudal Gap Filler Expanding Foam is an essential tool for construction, renovation, and general home maintenance. Whether you are filling a structural gap after a window installation or sealing a hole where a pipe exits a wall, this foam provides a structural, rot-proof seal that stands the test of time. At ECO Heat Shop, we provide the industrial-strength hardware required to keep your home insulated and protected from the elements.

Advanced Insulation for Doors, Windows & Walls

Soudal’s formula is engineered for stability. Once cured, the foam can be easily cut, sanded, plastered, or painted, allowing for a seamless finish in any DIY or professional project. Its excellent filling capacity makes it far more effective than traditional caulks for large openings. It acts as a weatherproof barrier, preventing moisture ingress and deterring pests from entering through wall cavities or floorboard gaps.

Technical Specifications

  • Brand: Soudal
  • Base: Polyurethane (PU)
  • Application: Handheld straw-grade (no gun required)

ECO Heat Shop Tip: For the best expansion and fastest cure, lightly dampen the surface with a water sprayer before applying the foam. Remember that the foam will expand significantly, so only fill gaps about 50% full. Using expanding foam is a sustainable way to lower your carbon footprint by reducing the energy needed to heat or cool your property.
