Heated extensions on Matchborough, Winyates and Church Hill terraces
Terraced houses make up 27% of Redditch homes, and the terraces on the new town estates often gain heated extensions. A typical build is a single-storey kitchen or garden room at the back, with wet underfloor heating pipes clipped to insulation and the screed laid over the top.
Without a good screed, those pipes cannot do their job. It holds the pipes in place, spreads heat evenly and gives the floor finish a flat, solid base. Two things matter most. First comes depth over the pipes. Liquid screed needs 25mm or more above them, which takes the floor to roughly 45 to 50mm overall, while sand and cement wants about 45mm of cover. The second is encapsulation. Any gap around a pipe leaves a cold spot and a weak area in the floor.
A pumped liquid screed for the extension flows fully around the pipes and is usually thinner, so it warms up faster. For a small room, or one that could get wet, sand and cement laid by hand remains a sound option.
On the morning of the pour we expect to find the insulation and membrane down, edge strip fixed round the walls, and the pipework filled and pressure tested. Our insulation and membranes service can supply or check that layer. We work the insulation and screed depths back from the floor level in the original house, so the new kitchen or garden room finishes flush with it.
Switching the heating on in a Redditch home
A new heated screed should not be warmed straight to full temperature. Heat can normally go into a calcium sulphate floor after roughly 7 days, but a sand and cement one needs 21 days or more. Even then the system is brought up slowly: a low flow temperature first, nudged up a little at a time over several days, and held there before anyone lays flooring. We hand over that schedule with the floor. Keep a note of the dates, because the flooring fitter will want to know when the heating went on and when it was turned down again before laying.
Retrofit is harder than new build. Where older houses in Headless Cross and Webheath are renovated with a new membrane and insulated screed, adding heating at the same time means the insulation, pipes and screed all have to fit within the depth available. Sometimes that means digging the old floor out further, and sometimes a thinner calcium sulphate product is the answer, which our anhydrite flow screed page explains.
If your project sits just outside the town, the same service runs in Solihull and other places nearby.
