Small kitchen in a self contained detached annexe Best way of connecting / cable sizing for an Oven & Induction 2 zone hob Oven has plug on it and 2.2kw Hob is rated at 2.8kw. Is it best to run a 6mm to a single 32a dp switch , then a combined outlet plate behind oven or is this overkill ?

So if timber kerbs are already built what flashing do I need to buy though?? Im obviously trying to avoid going above the 150mm (build regs) upstand height

We have a 15 degree pitched warm roof with Sarnafil. It has 2 standard GGU MK06 Velux windows. WHAT IS THE CORRECT FLASHING ??? Or Correct flashing method?? My carpenter has built the kerbs ready, to which the Sarnafil fitters have covered right over the top I'm tired of going between Velux...

Apologies , for confusing things. I will put celotex between timbers, before plasterboard i believe i have to put a vapour barrier or foil backed plasterboard. Im trying to avoid the cold bridging on timbers. I thought multi foil was ok as long as you had air gap one side. Therefore i thought...

Hi Garden detached room under construction . Warm roof will be used (18mm osb then 100 celotex then 18 osb) Query : Insulation with the eves at end of joist runs, as there are noggins etc please see attached Before answering - thanks

Thanks woody Do you mean tape over all the celotex or just the joints and joists I normally tape over joints and joists as a rule - will this enable me to avoid putting polythene up , as long as monitor things as above

Woody Im confused little , please ignore my lack of knowledge; Please note the construction - Im' just concerned with finishing the ceiling. Celotex is tight to rafters...from inside looking up So if I fix a polythene vapour barrier straight to the celotex ? Then the OSB 3?

if i staple VCL then i use OSB 3 straight on top would that be suitable ?

sarnafil , underlay on OSB is main roof as its a single mono / low pitched roof (so roof not breathable like tiled /breathable felt type) There is 50mm gap above the 100mm celotex
