Underfloor heating is becoming increasingly popular for its comfort and discretion. But it also raises questions of compatibility with the materials used, particularly wall plaster. Is it possible to apply natural plaster to an underfloor-heated wall? Here's what you need to know.
Why does underfloor heating raise questions?
A wall in contact with an underfloor heating system is subject to thermal stress. It is therefore important to ensure that the wall covering does not impede heat diffusion, that it does not crack and that it retains its properties over time.
Natural coatings: real thermal allies
Plasters based on lime and marble powder, like those developed by Absolin, are naturally breathable and flexible. Their ability to let warm air circulate while resisting temperature variations makes them compatible with underfloor heating. What's more, they emit no toxic compounds when heated.
A few precautions to take:
- Respect drying times before heating
- Apply thin, even coats
- Use a coating formulated to resist thermal expansion
Properly applied natural plaster provides an attractive, healthy and high-performance finish, perfectly suited to underfloor heating. An ecological choice without compromising on comfort.
