Maximum Sceed Thickness For Underfloor Heating
HomeWhen it comes to maximum screed thickness for underfloor heating heating (UFH) there are a number of variables to consider. UFH can be more energy-efficient than traditional radiators and it also makes for a more comfortable floor but it’s important that the correct system is installed to ensure the best results. One crucial factor is the maximum screed thickness for underfloor heating as this will determine how well the system works.
The type of floor screed that is used will also play a role in this as different options can offer different advantages. In general, a traditional sand cement screed should be at least 6 cm thick. This is particularly important with UFH because it’s essential that the pipes are covered and this will help to maximise the efficiency of the system.
Understanding Maximum Screed Thickness for Underfloor Heating
If a semi-dry system is used then the heating pipes are placed in the insulation layer and this can allow for a much thinner finishing screed. This is often more cost-effective and can be suitable for renovation projects, apartments and timber-frame constructions. However, the downside of this is that there’s a slightly higher risk of moisture ingress and it may require more maintenance than a wet system.
Pumpable self-smoothing screeds, also known as liquid screeds are another option. These can be laid as bonded or unbonded and they can be used to a depth of up to 50mm. However, it’s worth bearing in mind that these products are proprietary and recommendations will vary from supplier to supplier.
