PIR/Floor Insulation

Improve thermal performance and reduce heat loss with our range of PIR / Floor Insulation, ideal for insulating ground floors, suspended floors and renovation projects. PIR insulation boards are a popular choice for modern builds and upgrades thanks to their high insulation value and slim profile, helping you achieve excellent efficiency without taking up unnecessary space. Whether you’re insulating beneath flooring, between joists, or as part of a new floor build-up, PIR insulation helps create warmer, more comfortable interiors.

PIR floor insulation is commonly used in extensions, refurbishments and new builds, helping reduce drafts and heat loss through floors—one of the most important areas to insulate for overall energy efficiency. It’s ideal for use under concrete floors or between timber joists depending on your project requirements. Correct installation also helps support building performance and can contribute to lower heating costs over time.

For best results, choose the correct thickness for your build, fit boards tightly to reduce gaps, and use suitable membranes or sealing methods where required. Preparing a level base and following recommended installation guidance helps ensure the insulation performs as intended and delivers long-lasting benefits.
