Hi, I’m going to be at the will of building control/planning as to whether or not I can keep a suspended timber ground floor in my Small Mission Hall in the Outer Hebrides. Whilst I wait for the outcome, I wanted to look into both options. It’s a small building internally (7.500m x 4.500m) so I’m not having a main boiler/central heating system/heat source pump etc. so water is out, I’ll be going for an electric system. I maybe looking at a solar feed system as well. A replacement concrete floor with electric underfloor heating seems a little more straightforward. Possibly better because of its thermal mass acting a bit like a storage heater? However, is it possible to do similar with a replacement suspended timber floor and still utilise relaying the existing floorboards? Would the result (if possible) be equal in terms of its thermal performance compared to a concrete floor? What are the pros/cons either way? Any advice or suggestions welcome…
I have for the last year or more been assuming that I would have an insulated-concrete-raft floor in my modern bungalow, but I am now having second thoughts. The alternative is to have a timber-cassette floor *. But I have a constraint which is making me re-consider things: height: a ridge-height limit **. Anything that I can do to lower my dwelling's height is attractive as I am struggling to get under the limit. A timber-cassette floor filled with PIR could easily be 200mm thinner ***. The reason I favoured a concrete raft was that I felt a timber-cassette floor may well feel insubstantial, hollow and flex. But… am I wrong? Can a timber floor be made or feel as solid as a concrete floor? For example, would something as simple as a biscuit screed do the job (I have never seen one)? I would be grateful for your thoughts. - - - (* By the way, my foundations will be screw piles. The floor will have no direct contact with the ground surface.) (** And I have a no-dig requirement too.) (*** The build-up of the concrete-raft floor will be 775mm for a U-value 0.10 W/m².k, as follows: small pea shingle 50 mm, Cellcore HX-S heave protection 225, EPS 300 mm, reinforced concrete raft 200 mm.)
