The in-screed underfloor heating system with clip rail fixing is a low-profile hydronic heating solution designed for installation within a cementitious screed layer above the structural slab. The system uses clip rails to securely hold the pipework in position, ensuring consistent spacing, precise layout, and stable installation throughout the entire floor area.

The pipes are fastened using clips. Once encased in the screed, the system delivers even and fast radiant heat distribution across the surface, providing high thermal comfort and efficient energy performance.

This method is particularly suitable for renovation and new build projects where reduced floor build-up height is required. It also allows for quicker heat response compared to full in-slab systems due to the reduced thermal mass above the pipes.

The clip rail installation ensures the pipework remains fixed during the screed pour, minimising movement and maintaining optimal design spacing for balanced hydraulic performance and uniform heat output across all zones.
