Was planning on using foam sheets behind plasterboard but want to leave out now due to a number of reasons.

Hi Bobasd, Thanks for that. Would it be advisable to use moisture resistant plasterboard or would standard be ok? Thinking of using 9.5mm to keep cost down.

Hi, I am building a garden studio and wanted to know if it's okay for plasterboard to touch dpm or vapour barrier on single skin wall and if so should i use moisture resistant plasterboard. I have the dpm on a concrete slab which goes up two courses of breeze blocks (one course is under...

Hi, About to put timber frame up on breeze blocks and thinking about not including the foam insulation to cover the two courses of breeze blocks and just having insulation in the timber frames. Would it be ok if plasterboard touches the dpm which goes up the wall to links in with the dpc? And if...

Hi, Would it be okay to fit the 100mm loft insulation into the 100mm frame or does there have to be a gap in there somewhere? Concerned about the insulation touching the osb boards Cheers

Hi, Thanks endecotp. I was thinking about putting insulation in the frame as well. That's an interesting idea extending frame to be flush with block wall foundation. I will look into which is the most cost effective. Thinking about loft insulation in walls as much cheaper but not sure if it...

Hi, Thanks Woody for your advice. I have uploaded drawing with concrete slab thickened ends. As it is essentially a shed I was hoping I could get away with thickening the ends but best to do it right and shouldn't be much extra work. I have moved the insulation next to the block wall to inside...

Hi, In regards to woody's advice in putting the dpm going up the inside of the block concrete wall. Would I be able to fit standard 12.5mm plasterboard next to the dpm or would the thermal bridging coming from the floor up the wall cause a problem? Also where I use vapour barrier over the...

Hi Woody, Thank you for advice in the drawing. I thought the dpm would have to be under the slab and on the outside of the wall but happy if its better to fit inside, it would also make it easier to fit. Also happy to save money by not having to use sand. In the drawing you have put a blue...

Hi, Thanks Notch7 for quick reply. Its early days with working out the details and you have pointed out an issue which I have been thinking about. Would it be worth taking the 25mm external foam so it wraps around the side of the concrete slab to reduce damp penetration and thermal bridging? I...

Hi, Thanks for the replies. I have uploaded a drawing to show my thinking. Although more expensive I was thinking about using a uv breather membrane at the bottom as I understand normal breather membrane not good with the sun. I may use polythene suggested by woody. As the inside floor level...

Hi, Planning on building a 4m x 7m timber summerhouse with shiplap or similar cladding and would like to know if its a big no no to take the the breather membrane down to the ground? The reason I would like to do this is to hide the 150mm exposed external foamboard I am fitting below dpc. I am...
