I am designing and pricing to build a studio that is under permitted development , it will be timber framed. 6x2 floor joists 4x2 walls and 5x2 roof joists "flat roof". I have designed it to receive 100mm celotex in the walls floor and ceiling. I a now wondering if this will be enough insulation?
I don't know who to ask hence asking on this site or how to work it out.
The studio has a total area of 31.25 cubic metres. The joists will be suspended on concrete piers 50mm off of the ground. The walls will be 3mm skim on 12mm plasterboard on 4x2 C16 studs 100mm celotex with 12 mm WBP ply then a tyvek membrane 2x1 treated baton then vertical cedar cladding. The roof is 3mm skim 12mm plasterboard 5x2 C16 joists 100mm celotex 25mm vent gap 18mm OSB then EPDM roof covering.
There is one set of UPC french door 1800 x 2100mm and 2 windows 600 x 2100 all up to current regs.
I appreciate i may be asking for more help than the norm but this is one of the biggest jobs I've priced since being SE and I just want to be surer. Thank you.[/quote]
