    Solid underfloor heating (UFH) solution



    Ideally suited to construction and new build projects,  the most traditional type of underfloor heating system is where UFH pipe is either stapled to insulation (clips and clip rail system) or laid into panels (castellated system) and is then covered in screed to complete a finished floor.


    Screed is a cementitious top layer that is poured over a concrete flooring or structure to produce a level finish.


    A typical screeded floor construction generally takes the form of:

    • Structural slab or oversite concrete
    • Thermal insulation and edge insulation
    • Waterproof membrane (Building regulations)
    • Pipes location and securing system (castellations, Clip rail etc)
    • Underfloor heating pipe (with oxygen diffusion barrier)
    • Screed or concrete conducting layer (40mm – 75mm)
    • Floor finish (Tiles, Engineered wood, Carpets etc)


    Screed and concrete types vary but generally include: standard ready mix concrete, Semi dry sand and cement mixtures, Polymer aided, fibre reinforced screed and Calcium sulphate flow screeds (anhydrite or alpha- hemi -hydrate). Screeds are either applied using a barrow and concrete float or can be pumped onto the pour site.


    All screeds have different characteristics based on application but all must have recognised British Standard or DIN Standard accreditations.
