FastWarm Perimeter Edge Insulation is a high-performance accessory designed to enhance the efficiency and longevity of screed and underfloor heating installations. Used around the perimeter of a room, it helps minimise heat loss, improve energy efficiency, and deliver a professional, compliant floor finish.
Manufactured from flexible, high-quality insulation material, this edge strip creates an effective thermal break between the screed and surrounding walls. It also allows for natural screed expansion and contraction, reducing stress and the risk of cracking over time.
Supplied in a 25 m roll, with a 100 mm height and 5 mm thickness, FastWarm perimeter edge insulation is easy to cut, handle, and install. It is suitable for both professional installers and DIY users and is compatible with FastWarm underfloor heating systems and most screed applications.
- Superior thermal performance – reduces perimeter heat loss for improved energy efficiency.
- Stress relief protection – allows screed to expand and contract without damage.
- Easy installation – flexible and simple to cut to required lengths.
- Universal compatibility – ideal for use with FastWarm underfloor heating and most screed floor systems.
Ensure your floor installation performs to its full potential. FastWarm Perimeter Edge Insulation is the professional choice for smarter, more efficient, and longer-lasting underfloor solutions.
