Heating under rebuilt floors in Coundon and Cheylesmore
Once an old solid floor has been broken out, the hardest part of a retrofit is already done. What remains is fitting the new layers into the height available, because the finished floor still has to meet the front door, the stairs and the next room. Measuring those heights before the dig-out starts saves surprises later.
The layers run in order: damp proof membrane, insulation, edge strip, pipes, then screed. Fitting and testing the pipes sits with your heating engineer, since K & B does not install them, while we inspect the insulation, membrane and edge strip and provide whatever is missing through our insulation and membranes service.
The screed depth comes next. Pumped liquid must finish 25mm or more above the pipes, giving a 45 to 50mm floor. A sand and cement version puts about 45mm over them, adding to the overall depth. In a house where every millimetre counts, liquid is usually the answer, and it flows fully round the pipes with no air pockets, giving faster warm-up and better heating efficiency. The pour itself is covered on Coventry liquid screed for extensions.
Sand and cement still suits some rooms, especially those that may get wet, and rooms too small to make pumping worthwhile. The sand and cement page for Coventry covers that method. Whichever screed is used, the surface is finished flat enough for tiles, LVT and engineered wood.
Commissioning heated floors in Coventry homes and flats
The heat-up is where a good screed can still be spoiled. Calcium sulphate can first be warmed at around the 7 day mark; sand and cement holds out until day 21 at the earliest. The setting then climbs gradually across several days, since going straight to full can crack the floor. Our written schedule means the heating engineer and the household follow one set of dates.
In flats, the build-up includes acoustic layers. Post-war blocks in estates like Tile Hill, such as the Banana flats on Jardine Crescent, have acoustic screeds as part of any refurbishment, and heating added there has to sit within that acoustic build-up rather than replace it.
Newer homes give more room to work with. 11% of Coventry's homes were built in 2015 or later, and new homes and extensions are the simplest places to fit a heated screed. A garden room or rear extension follows the same rules at a smaller scale.
