How Thin Can Liquid Screed Be?

There are many different types of liquid screeds available to suit many other use cases; some specialist types can be installed as thin as 12mm.

Recommended Depth 

The general recommended depth of liquid screed over underfloor heating is 50mm. Having your screed layer be as thin as possible is important, it means the heating system will be more responsive; the heat from the piping has to travel through a thinner layer. Liquid screeds are very thermally conductive making them more energy efficient than other options, meaning that you can run lower temperatures at your thermostat and achieve the same amount of effective heating.
