Hot water underfloor heating Lithotherm

residential

Lithotherm underfloor heating system is:- an ideal underfloor heating system for use with air/ground source heating a very fast underfloor heating installation, allows floorboards to be fitted same day. a dry, 45mm screed replacement, creating a thinner screed layer with absolutely no dry time. used where faster response times are important, keeping heating costs down. part of the Lithowood alternative to concrete floor slabs. Where is it used? The Lithotherm system is best suited to solid floors and normally sits on top of the insulation layer. The interlocking tiles allow tiled and floating floors to be laid over the top of the system and special profiled timber battens allow floor boards to be fixed down. Can be laid over Foamglas aggregate to create floors without concrete slabs. How strong are they? The Lithotherm tiles have a compressive strength of 9.64 N/mm² so are stronger than a normal concrete block. They have a flexural strength of 2.03 N/mm². What is their thermal conductivity? The Lithotherm tiles are not designed to be a thermal insulator, in fact they are quite the opposite and designed to disperse heat as well as possible. However, their thermal conductivity is around 0.89 W/mK. How is it used? When laying the Lithotherm UFH System on to insulation it is important that the substrate is solid and does not move. If laying directly on to a concrete floor it is advisable to use a thin layer of an underlay material, such as the UdiSTEP wood fibre product.
