Solid

Solid floor underfloor heating systems have the underfloor heating pipework embedded in a concrete or screed.  They include concrete screeded floors and Block and Beam floors with a screeded finish.  Myson Underfloor heating systems are available for all of these constructions.  The design and installation of the concrete or screeded floor must conform to the appropriate British Standards and Codes of Practice including BS 8204-1:2002 In-situ floorings and BS 8000:Part9:1989 Workmanship on Building Sites.  For all forms of solid floor construction the design requirements are based on the structural requirements of the floor.  Myson Underfloor Heating presents few constraints in this respect.

• Within or directly on top of the sub-base, a Damp Proof Membrane should be included. 
• A layer of insulation is laid directly on the sub-floor, which must meet the U value requirements for Building Regulations as well as the requirements to reduce heatloss. 
• To avoid damage to this layer of insulation and to prevent screed from bridging to the sub-base a protection layer is included on top of the insulation. If other types of insulation are to be used then a protection layer must be laid over the insulation. Protection layers do not act as a Damp Proof Membrane or Vapour barrier and these, if required must be incorporated elsewhere in the floor structure. 
• The Myson Diffu-Pex underfloor heating pipework is then fixed in place using a suitable anchorage system. 
• Finally the screed is laid following the appropriate British Standards and Codes Practice. Screed materials should not include any insulating materials and a minimum screed thickness of 75mm
