Heating a whole open-plan room in Frimley
A further 36% of Frimley's housing dates from 1973 to 1999, and houses of that age are typically extended or knocked through to make one big kitchen and family room. When the old kitchen floor is dug up at the same time, the heating can run across the whole space, not just the new part.
That makes the build-up a question of height. Insulation boards, a damp membrane, pipework and screed all have to fit under a finished surface that lines up with the hall and the rooms beyond. Pumped screed must clear the pipes by 25mm or more, normally 45 to 50mm overall, whereas a hand-laid mix wants about 45mm above them and comes out deeper. Where the old slab cannot be lowered, the thinner liquid build-up can leave room for more insulation.
The screed must fully encapsulate the pipes. Air pockets slow heat transfer and leave weak points above the pipes. A flowing screed surrounds them naturally; sand and cement is packed around each run by hand.
Before the pour, the pipes should be filled and pressure tested so any leak shows while they can still be reached. Edge strip goes round every wall to allow the floor to move as it heats. If the insulation and membrane are not already in, we can supply and fit them through our insulation and membranes service. For typical depths, the screed thickness guide is a useful check.
Heat-up and flooring on Frimley heated floors
The heating should stay off until the screed has cured. For calcium sulphate that is usually from about 7 days. A sand and cement floor needs 21 days or more. Tell us when your heating engineer plans to commission, so the pour date leaves the screed that time first.
When the heating goes on, it goes on gently. The commissioning plan comes from your heating engineer: the flow temperature creeps up a little at a time across several days, holds, and then eases back down. A sudden full blast can crack the screed.
Heat speeds drying, but it does not replace testing. Tiles, LVT and engineered wood all need the screed at or below their maker's moisture limit, and a calcium sulphate floor also needs its laitance sanded off before anything is laid. Our calcium sulphate screed page covers that stage.
Pipe laying stays with your heating engineer, and the screed follows once they are done, so get both trades talking about dates early. Underfloor heating screed in Farnborough, under two miles away, follows the same approach.
