Cost effective, quick drying floor screeds for domestic and commercial underfloor heating achieve the best results. But how does a fast dry floor screed form part of an underfloor heating system?
Floor screed and underfloor heating systems
When it comes to underfloor heating you want to ensure that the materials and system you use provide you with an efficient set up that ensures the distribution of heat evenly throughout the building, this will also result in lower energy costs. A floor screed can be applied onto solid in-situ concrete ground floor slabs, any insulation layer or alternatively onto precast concrete beams. However, before you embark on any underfloor heating and floor screeding project it helps to understand how floor screed works to give you the best possible, long lasting and durable results.
What is floor screed made of?
Floor screed is usually made of a material that has similar properties to concrete, produced from a 1:3 or 1:4.5 ratio of cement to sharp sand, and can also comprise of cementitious and latex products as well as anhydrite binders and water.
What is floor screed used for?
Floor screed is most commonly used to level out a concrete sub-base, especially when it is particularly uneven, as well as giving more tolerance in the application of sensitive floor finishes and supporting stress during the drying process. When applied to underfloor heating, floor screed will be used to cover and bury pipes that are used within the system, therefore helping to deliver the best performance and aid the transport of heat.
What types of screed are there?
The three most commonly used types of floor screed are:
- Traditional screeds: Most commonly used to create a level surface in the final finish of a floor made up of sand cement
- Latex screeds – Self-levelling compounds: When a greater degree of tolerance is required for the application of sensitive floor finishes, this is applied to the top layer of a screed, with varying thicknesses from 1mm to 40mm.
- Heavy duty and reinforced screeds: Through the use of fibres or metal mesh, this is used to support stress upon the screed that can occur during the drying process. In addition, curling, cracking and shrinkage can also be prevented.
- Liquid screeds: Also know as free-flowing or Anhydrite screeds, these can be installed quickly and easily in a range of commercial and domestic environments.
