Expol Underfloor Insulation is a smart, effective way to enhance the comfort, energy efficiency, and value of your home. Suitable for both new builds and existing homes, Expol creates an insulating barrier beneath timber floors, helping to keep homes warmer in winter, cooler in summer, and reducing energy costs year-round.

Lightweight and easy to handle, Expol Underfloor panels are trusted by builders, professional installers, and DIY homeowners alike. Panels fit neatly between timber joists and are available in multiple sizes, making them ideal for a wide range of residential projects.

Manufactured from rigid expanded polystyrene (EPS), Expol panels won't sag over time. They are manufactured with flame-retardant, vermin-resistant, and help reduce noise between floors. Offcuts are 100% recyclable, supporting a cleaner, more sustainable approach to building and renovation. By improving a home's thermal performance, Expol also helps lower greenhouse gas emissions and promotes a healthier indoor environment.

Backed by a 50-Year Product Warranty, Expol Underfloor Insulation keeps homes warm, dry, and comfortable for decades to come.
