3. Installing of UFH Staple System Using the screed as a heat diffuser JG Speedfit pipe is secured with staples to rigid insulation placed over the concrete sub floor A variety of screeds can be used and are typically 65 75mm thick for sand cement types or 40 50mm for liquid pumped screeds The system is quick to install cost effective and can be easily adaptable to irregular room shapes Floor coverings can be laid when the screed is fully cured STEP To prepare the floor insulation should be fitted to a flat sub base The joints should also be taped and a membrane placed over the insulation STEP 4 Using the staple gun fix the pipework to the installation in the desired pattern see images on patterns of pipework Starting the first circuit 75mm from the perimeter and staples should be approximately 500mm apart More staples maybe needed on bends THINGS TO REMEMBER STEP 2 An expansion strip is required around the perimeter of the room to accommodate the expansion which will occur within the screed as a result of heating up This should be fitted around the perimeter of the room and taped to the membrane STEP 5 When using the pipe unroll it from the outside of the coil and do not try to uncoil it from the centre this will make the process easier Keeping the first run of pipe around the perimeter straight and using a gauge to keep the designed pipe centres even will also help the installation process e Insulatio

6. Advice It is important to carefully consider the ideal installation method for your underfloor heating project The pipe fixing technology offered by JG Speedfit Underfloor Heating will ensure that the right materials and methods are used for the job s requirements Step by step Installation Guides Installing the Manifold The installation of the manifold is an integral stage of a heating system The JG Speedfit manifold kits are for use on underfloor heating or radiator systems The manifold consists of two rails one for the flow and one for the return complete Installations normally fall within three categories SOLID SCREEDED FLOORS The screed is an important and integral part of the UFH system transferring energy from the pipes to the area to be heated The response of this thermal mass will depend on its depth and make up The usual depth of screed is 65 75mm thick but it is possible depths can be reduced to assist in improving performance It is suitable for us in either new build or existing properties PIPE LAYOUT IN SOLID FLOOR INSTALLATIONS The shape of the room and the position of the outside walls and windows will determine the pattern of the pipe layout The counterflow pattern is recommended although other options are shown opposite TIMBER FLOATING FLOORS Often found in the upper floors of a property a system is required where a solid floor installation is not suitable due to structural
