AquaLay is more than a panel that holds pipework, says manufacturer PCS. It is an insulated heat-transfer system designed to improve the response, control and efficiency of water-based underfloor heating.
AquaLay combines the best of traditional underfloor heating systems with the modern efficiency of high-density XPS insulation, the manufacturer explains.
The overlay panel with a core difference
Although traditional screeded and concrete floors with embedded heating pipes have served their purpose, their high thermal mass is increasingly inefficient in today’s more changeable climate. With these traditional systems, the entire floor mass must be heated before warmth reaches the room, making them slow to warm up and slow to cool down. When temperatures change quickly, heat can remain stored in the floor after it is no longer needed.
A better way to heat floors…
The patented design of AquaLay retains the proven heat-transfer qualities of cement-based systems without the same high thermal mass. Its lower-mass construction provides rapid, even heat distribution, faster warm-up, quicker cool-down and a closer response to heating controls, says PCS, improving comfort while reducing unnecessary energy use.
The result is responsive heating. Energy is used when it is needed, not stored in the floor after demand has changed.
Be ready for the future
From 24 March 2027, the Future Homes Standard will require new homes in England to use highly energy-efficient, low-carbon heating, making underfloor heating that operates effectively at lower flow temperatures and limits downward heat loss increasingly important. AquaLay is ready for this change: its patented heat-transfer core and high-density XPS insulation support responsive, low-temperature water-based underfloor heating and help floor constructions meet the requirements of the Future Homes Standard.

Manufactured in the UK
AquaLay is engineered and manufactured by PCS in the UK.
PCS has generations of experience in specialist construction materials and continues to invest in its people, manufacturing facilities, research and product development.
That investment supports greater control over product quality and consistency. It also allows the PCS team to develop products around the real requirements of installers, distributors, system designers and construction professionals.
AquaLay is the result of that approach, says PCS, a rigorously developed overlay panel built around a clear purpose. To transfer heat more effectively, reduce waste and help water-based underfloor heating systems perform at their best.
