Fitting heated floors into Wickford extensions
The awkward part of a heated extension is height. The new floor has to meet the existing house at the doorway, and everything must fit underneath it: insulation thick enough to stop the heat escaping downwards, the pipes and their clips, and a screed deep enough to cover them.
That is why a thin liquid screed suits these rooms. Pumped, it needs a minimum of 25mm sitting above the pipes, and that normally brings the finished depth to 45 to 50mm. Go hand-laid and the cover rises to about 45mm, leaving a thicker floor overall. On a tight extension, the difference can be the thickness of an extra layer of insulation.
The second reason is contact. Poured screed closes in around every loop and leaves no trapped air, which lets warmth spread through the slab fast and evenly. Sand and cement gets there too, provided it is packed down firmly beside each length of pipe. Our liquid screed page for Wickford explains how the pour works on the day.
Converting the garage at the side of a Wickford semi works the same way. A converted garage with heating needs the floor raised with insulation, a membrane, the pipes and a screed, all finishing at hallway level. Before the pipes go down, make sure the insulation and edge strip are right, because they cannot be fixed once the screed is poured. Sample build-ups for heated rooms are in our guide to how deep a screed should be.
Newer Wickford homes and switching the heating on
Only 13% of Wickford's homes were built since 2000, and just 3% since 2015, so a heated floor in the town is more likely to be a retrofit than part of a new-build plot. Proposals such as the 302 homes near Tresco Way would add to the newer stock. Where a new home is designed with heating in the floor, the programme is different: the build-up is drawn in from the start and the screed goes in plot by plot.
Whatever the house, the heating has to wait once the screed is down. Calcium sulphate can normally take warmth from around day 7. Hand-laid sand and cement needs at least 21 days before the heating goes on. When the system is first run, the water should start cool and be turned up a little at a time across several days. You get that plan from us on paper, and your heating engineer carries it out.
Turning the thermostat straight up is how many heated floors crack. Run gently, though, the system helps a calcium sulphate screed dry out faster before the LVT or tiles go down. If the installer has left out the boards or sheeting under the pipes, we can provide them through our insulation, membrane and preparation work.
