Where to Use

78mm Cellecta Hexatherm XCHiP insulation boards are ideal for use in underfloor heating systems, where high thermal performance and efficient heat distribution are required. Designed to reduce heat loss through the floor, XCHiP helps improve the overall efficiency of both residential and commercial heating systems.

Suitable for a wide range of underfloor heating applications, the boards provide a stable and durable insulation layer that supports heating pipes or systems while maintaining consistent thermal output. Their rigid construction ensures reliable performance under load, making them suitable for modern floor build-ups.

78mm XCHiP is commonly used in solid floors, suspended floors, and new-build underfloor heating installations, where energy efficiency and long-term thermal stability are essential. The lightweight design allows for quick and straightforward installation, helping to reduce on-site labour time.

Ideal for both domestic and commercial projects, Cellecta Hexatherm 78mm XCHiP contributes to improved building energy performance, lower heat loss, and enhanced occupant comfort in heated floor systems.
