SPECIAL – Edge Insulation 8mm x 150mm x 25m Roll with self-adhesive back and self-adhesive apron

The Edge Insulation 8mm x 150mm x 25m Roll is a premium polyethylene expansion strip designed for underfloor heating installations. It creates a critical thermal and structural barrier around the room perimeter, absorbing the natural expansion of concrete or liquid screed as it heats up, preventing floor cracking and structural damage.

This heavy-duty roll features a high-tack self-adhesive backing for fast, tool-free application to walls, alongside an integrated PVC apron. The apron folds down over the floor insulation perimeter to bridge gaps, acting as a watertight barrier that completely prevents wet screed from seeping down beneath the insulation panels.

Key Features & Benefits

• Self-Adhesive Backing: Bonds instantly to walls and perimeters, saving significant installation time on-site.

• Integrated PVC Apron: Seals the gap between floor and wall insulation to prevent liquid screed escape and cold bridging.

• Thermal & Acoustic Barrier: Minimizes lateral heat loss into structural walls while reducing acoustic impact noise transfer.

• Expansion Accommodation: Flexible 8mm thick foam absorbs the natural movement of heated screed to prevent floor cracking.

• Generous 25m Roll: Provides ample, continuous coverage for quick deployment across large domestic or commercial layouts.
