Underfloor heating (UFH) is an increasingly popular way to heat a home. It works by pumping heated water through flexible piping in the floor, which radiates heat upwards into the room. The system can be used in a single room, a corridor or the entire house. However, it’s important to make sure that the UFH system and floor screed are properly installed to avoid issues down the line.
When installing ufh screed and floor screed London properties should be careful to ensure that the right type of screed is used, as this will have a significant impact on how the heating performs. For example, some traditional screeds can develop problems such as excessive compaction and cracking around UFH pipes. This can cause the heating to work inefficiently and can lead to a poor level of comfort.
The best type of screed for underfloor heating is a modified screed such as FlexiDry. These types of screed are specially formulated to reduce compaction and cracking around UFH piping, whilst also acting as an energy efficient insulation.
Suitable insulation is also installed between the structural floor and the UFH loops. This prevents cold bridging and allows the screed to expand and contract consistently without damage to the pipework. The floor screed should also be installed as quickly as possible after the UFH is laid to minimise the risk of affecting the pipes. During this process it is vital that the screed is pressure tested to twice the working pressure and kept at this level until the installation is completed.
