Hi there appears to be no PRV pipe going outside as i mentioned above. I can see the PRV valve but it is inline on the heating return pipe so i imagine if it were to blow/leak then it would just leak inside the airing cupboard!

Hi I'm hoping someone might be able to offer some advice. Our Alpha CB24/28 boiler is losing pressure overnight and needs continual topping up. In normal operation throughout the evening (going on and off every hour or so) it's fine, but if left for any considerable time ie over night...

I've been building my wooden garage and its almost finished the last little bit left to to is to finish installing the roof insulation and board over it. the roof stucture is as follows from outside in 1) asphalt shingles 2) NonBreathable Roofing underlay...

yep but cheers for the link

i was hoping to keep the insulation as thick as possible to help retain the heat as i'll probably be in there most eveings so anything that helps it keep warm is a plus :) The wokshop is just for my tinkering not a commerical one. The workshop has had armoured cable run to it buried...

i suppose its an option but i'd really prefer to keep it all hidden away if possible

Hi I've had a search but not found anything that answers my question. I'm hoping one of you kind folk might be able to help me. I've had a small wooden workshop built that's timber clad on the outside and will be ply lined on the inside. I'm planning on fitting 100mm foilbacked Kinspan...

due to the size of the roof (large 10m x 3m) and that its only going to be used occasionally(evenings & weekends) i don't want to spend an absolute fortune on the expensive foam insulation. because i'm using felt shingles i have to have them attached directly to the roof boards rather than...

could someone be so very kind as to give me some pointers with regards to insulating my timber workshop roof. The roof will be covered with felt shingles and i'd like to use rockwool to insulate due to the size and cost. The problem i'm trying to get to grips with is that the roof truss...

sorry i dont think i fully understood your question before. I wasn't entirely sure what a "cut roof" was. I'm basically just making the roof frames at home on site as it were but just wasn't sure of the best method of screwing them all together. is it simply a case of using screws or would...

The problem is the walls aren't exactly parallel due to a narrowing drive so i need trusses so that the cross members can sit ontop of the header plates rather than cutting bird mouths into the rafters as the roof then wouldn't be level etc hope that kind of makes sense

I need to make 17 trusses for my timber workshop (10m long building based on 600mm centres). The trusses will span 3.4m and have a 18 degree pitch i've made a jig to cut all the wood angles but i'm still abit unsure about the best method to join them all together. Would it be ok to use...

briliant! thanks very much for the quick reply! also its probably a stupid question but which way should i overlap the sheets (assuming they are horizontal) and viewed from the inside of the building

i'm going to be insulating my timber workshop shortly and i'm just wondering what is the best method for attaching the polythene vapour barrier to the the timber studwork? I've read various methods on different forums and am slightly confused is it ok to just staple it to the framework? or...

I've got another couple of questions I'm hoping you might be able to help with :) with regards to the roof insulation do i take it that its the same method as the walls ie I'd need a breathable membrane covering the roof over the roof boards before i fit the felt shingles and then on the...

That's brilliant!!! thanks ever so much for your detailed reply!! I'll be sure to update once i get to the wall stage Cheers Matt

Hi I've done a search already but not quite found the answer to my specific question. Basically i'm building a new wooden garage\workshop from scratch. The walls are going to be made from 2"x4" and clad in waney edge\featheredge boards. I'd like to insulate it properly as i'll be...
