A polyurethane cast floor is more elastic than epoxy self-levelling floors and is also more resistant to cracking. Also the small thickness (between two and three millimeters) makes this cast floor ideal in combination with underfloor heating.
2. Trowel floors with underfloor heating
Trowel floors or stone carpet can be very well combined with underfloor heating. This floor has a more open structure than other cast floors. Therefore, there is a perfect combination of isolation and permeability. That could lead to a power 30% lower power consumption than average with other types of floor covering.
3. Epoxy cast floor with underfloor heating
Epoxy cast floors are very popular, but unfortunately cannot be combined with underfloor heating. Epoxy can not budge-and turn off tensions. As the warmth of the underfloor heating can lead to expulsion (later contraction) cracks will occur.

The floor in a layer thickness of 2 to 20 mm is made up of cement, binders and various chemical additives. Yet it is not recommended in combination with underfloor heating Edinburgh.
5. Other types of seamless floors
Other types of cast floors such as terrazzo, concrete cire, mortex, etc. may also be combined with underfloor heating Edinburgh. Yet the risk of crack formation is always present. It is therefore advisable to always speak to an expert before making a cast floor with underfloor heating.
