Can liquid screed be used with underfloor heating?

Yes, liquid screed can be used with underfloor heating systems. In fact, it is a popular choice for underfloor heating installations because of its excellent thermal conductivity and self-compacting properties.

When installing underfloor heating with liquid screed, it is important to ensure that the heating pipes or cables are properly secured in place and that there is sufficient insulation below the pipes to prevent heat loss. The screed should be poured to the correct depth, typically 50mm, but this depends on the specific underfloor heating system and the desired thermal performance.

It is important that the underfloor heating is put through a commissioning cycle in accordance the manufacturers guidelines and prior to the application of floor finishes. Commissioning ensures that the underfloor heating system works correctly with the liquid screed floor and the system operates efficiently and effectively, minimizing any potential for costly repairs or issues in the future. It also ensures any excess moisture evaporates from the screed prior to the installation of the final floor covering.

Overall, liquid screed is a suitable and effective choice for underfloor heating installations, providing a smooth, level surface with excellent thermal conductivity and low resistance to the flow of heat.
