Please view below the different methods used by Thermo-Floor UK Limited to achieve excellent results when using Underfloor Heating Concrete. The types used are Concrete Slabs For Wire Mesh, Expansion Joints and Movement Joints.Contact Us...
The sub-floor is laid with rigid thermal insulation boards which reduce downward heat losses and provide a base on which to fix the underfloor heating tube. The floor edge is fitted with perimeter insulation which provides a barrier against perimeter heat losses and allows for expansion and contraction of the screed. The clip rail panels are laid over insulation and secured with fixing staples. The pipe is inserted into the clip rail and connected to the manifold, relevant tests are carried out to ensure system integrity and screed is laid over the top. NB: Heated screed or concrete floors will expand and contract slightly during use, the edge insulation is normally sufficient to take up this movement. In some instances and dependent on the desired floor finish (marble, stone, tile) screed expansion joints will be required.
Heated screed or concrete floors will expand and contract slightly during use and with a floor finish of tile, marble or stone screed expansion joints will be required. Thermo-Floor polyethylene pipe is made to withstand this movement however pipes that pass through the movement joint are covered with conduit sleeves as a safety precaution.
Movement Joint -If there is the requirement the underfloor heating pipe work must run across movement joints in a structural floor slab, a conduit sleeve is fitted to the pipe to allow sufficient movement.
