Pipe Clips & Fixing Rails
for Underfloor Heating.

Winkler Technik was founded in 1977 by Dr. Wolfram Winkler and is now led by the fourth generation of the family. The original U-Rail invention has grown into a complete range of fastening systems for underfloor heating, wall heating and ceiling cooling.

From private homes and office buildings to industrial facilities and stadium turf heating - our products are installed worldwide across every substrate: screed, concrete, soil, mesh panels and all common insulation materials.

U-Rails - including U-Rail ZS, Penta- and Octarail variants - hold the heating pipe at precisely defined spacing. Staple systems with staples and setting tools enable fast installation across large areas. Clips secure the pipe to mesh panels or hard substrates, holding pins and plastic nails fix the rails in position, and plastic bend supports maintain the correct bending radius at the manifold.

Every component is designed to work as a system - manufactured in Germany and Switzerland for consistent quality, short lead times and the reliability that professionals have counted on for decades.

Which rail suits which insulation? Which clip holds a 17 mm pipe on steel mesh? At Winkler Technik, those questions go straight to our sales and application engineers - by phone, email or in person. Direct access to the inventors of the U-Rail.
