Adding underfloor heating in a Ferndown renovation
Homes built between 1973 and 1999 make up 32% of Ferndown's housing, and with the post war stock before them, many are now at the age for a full renovation. When the ground floor is dug out to add insulation, there is a chance to add heating pipes as well, and the screed then does the job of spreading heat and carrying the floor.
The depth has to fit. Taking the old slab out creates the space for insulation, pipes and screed, but the finished floor must still meet door thresholds and the other rooms. With liquid, 25mm over the pipes is the minimum, so the screed is about 45 to 50mm all told; with sand and cement the pipes want around 45mm on top, which makes the whole floor thicker. Where depth is tight, liquid screed usually wins.
It also wraps the pipes fully. A flowing screed leaves no voids around them, so heat moves into the floor quickly and evenly. Hand-laid screed can be used, but compacting it around pipes needs care.
Edge strip, membrane and insulation all get a look from us before the pour, and we can bring them if you have none. Fixing the pipes and pressure testing them is your installer's job. For the calcium sulphate grades often used over heating, see anhydrite flow screed in Ferndown, and for depths in detail, our screed thickness guide.
Heated extensions and garden rooms in Ferndown
Council tax bands F to H cover 21% of Ferndown homes, and rear extensions and garden rooms are common jobs on the town's detached houses and bungalows. Building a new extension is easier, because nothing old is in the way of the floor. Liquid screed over the pipes flows into every gap and can cover the whole room in one pour.
Heat-up is where floors go wrong. On calcium sulphate the first heat can usually go in at around 7 days; sand and cement wants at least 21 before it sees any. The temperature should then rise in small steps over several days, not be turned straight up. A floor heated too hard, too soon can crack or curl, and a crack in a heated screed is awkward to repair with pipes inside it.
The loops of pipe, the manifold and commissioning the system belong to your heating engineer; what we bring is the screed over them and advice on warming it up. For how the two screed types compare on a heated floor, see liquid screed for Ferndown extensions.
