Thanks for the quick answer. I'll have about a 75mm ventilation gap above the 100mm celotex between the rafters with 40mm fixed under the rafters. This was specified by my BCO. It's slightly less than I'd planned as I over compensated for my P/R and cavity, which is no bad thing I suppose...

Hoping for a bit of advice if possible.. I am about to place insulation (40mm celotex) under my rafters in a new flat roof and then fix foil backed plasterboard under this. Do I still need a VCL stapled or fixed between the insulation and plasterboard? Thanks in advance Dan

Hi all, I am going to start putting up the walls for my extension very soon. I am planning on using 100mm dense concrete blocks for the outside which will be rendered, 100mm cavity full filled with 100mm dritherm 37 and then 100mm Celcon Solars internally finished with dot and dab...

Hi Noseall, Had the BCO round today and I will be using concrete lintels to bridge the pipe work. He mentioned that no bridging would be necessary for the oversite. I am building this extension all by my lonesome and had the footings approved today and poured the foundations this afternoon...

Cheers mate. To be honest I will go for the steel to be on the safe side. What about bridging over for the oversite? Less load on the floor, what do you think? Thanks again, Dan

Many thanks for the quick responses. I will be taking the patio up and digging down to allow for new hardcore, etc. Thanks again, Dan

Hi all, I've just joined today and already this is my second request for some advice!! I am planning to increase the size of an extension I have on the back of my house (1956 semi). It is currently 3 x 3 and I'm hoping to extend to 3 x 6. Where I plan to extend is currently a very solid...

Noseall, Cheers for the quick reply mate much appreciated. I think I understand what you mean. Cut a semi circle in the flashing and dress this around the bottom half of the protruding waste pipe and continue the flashing on. Then make a plywood box to dress the sides and front of the pipe...

Hi all, I'm new on this site and would really appreciate people's views on a problem I have with my extension. I shall explain. I have a 3m x 3m kitchen extension on the back of my 1956 semi which I intend (hopefully!) to turn into a 3m x 6m extension to essentially double the size of my...
