Warmup WHS-X-EDGE50 Undefloor Screed Perimeter Expansion Strip 150mm x 50m

The Warmup perimeter expansion strip roll future-proofs screeded water underfloor heating installations by absorbing differential movement between the floor and surrounding walls. It is installed around the perimeter before the screed layer to accommodate for natural expansion and contractions. The insulating construction reduces thermal bridging to help limit heat loss, while the integrated polyethylene gaiter provides a secure seal that supports long-term system performance.
