Underfloor heating and cooling

Klett wet installation

Infinite possibilities for new-build and renovation projects

Klett is an easy-to-install, leak-resistant radiant floor heating and cooling system designed by Uponor. It is fast and easy to lay, without the need for additional accessories such as clips, binaries or clamps. A self-attaching strap fastener wrapped around the Uponor Klett pipes makes it quick and easy to secure the pipe to the smooth insulation board.

Both the system and the components are tested and certified by the best authorities in accordance with industry standards, thus guaranteeing the functionality and reliability which characterise all Uponor systems. Uponor Klett comes in a wide range, making it a particularly versatile product – with the result that it is not only a highly innovative system, but also an extremely effective one offering real benefits.
