Underfloor heating systems for the climate turnaround

We need to reduce heating energy consumption in buildings in order to achieve the climate turnaround. This applies in particular to existing buildings. Surface heating systems, such as underfloor heatings play an important role. They indeed work with lower flow temperatures than conventional radiators and distribute the heat more evenly throughout the room. This means less energy is consumed and less CO₂ is generated. For this reason, underfloor heating systems are particularly environmentally friendly.

Energy sources which protect the environment like heat pumps or solar systems often provide lower flow temperatures than oil or gas heating systems. With these forward-looking energy sources, underfloor heating systems therefore make a lot of sense.

There are different types of underfloor heating systems, in particular electrical and hot water heating systems. Almost all heating systems must be covered with a specific heating screed, which should have a high thermal conductivity and at the same time be resistant to frequent heating and cooling stages. Calcium sulphate or cement screeds are well suited for underfloor heating systems.

Saint-Gobain Weber supplies high-quality calcium sulphate heating screeds which neatly enclose the pipes of the underfloor heating systems, transport the heat and at the same time harden with low stress.

The thin-layer systems only require a pipe cover of a few millimeters and are particularly suitable for the renovation of existing buildings where only limited room heights are available.

We offer a total of seven installation recommendations for floor constructions with underfloor heating in order to make the work of screed and floor layers easier.

They cover all installation situations, from standard applications to special requirements, whether electric or warm water heating systems, in a bonded system or on a separating layer up to retrofitted milled-in old screeds and also surface heating systems in outdoor areas (for ex. on loading ramps).
