First time posting here but had some good advice from other threads, thank you. I am NOT a builder so I need all advice at SIMPLE level.
Had a loft conversion done on 2 bed bungalow - Due to limited cash - conversion getting done in stages, all the structural work is now done. Next job is insulation, boarding and final fix on electrics and plumbing.
I am trying to source some cheaper materials now but I am confused about how much and what kind of insulation I need to put in the roof prior to boarding. We are also tight for head space to trying not to lose too much.
builidng inspector said (I think) 100mm insulation, batton, 50mm gap and board our rafters are 80mm . So I get that we have to make the rafters bigger during the process.
I Had a search on the internet and it would appear that Celotex and Kingspan have a great U rating and are thinner than rock wool? More expensive Which would you reccomend. I really want to save money but done want to make life difficult for myself
Not sure does the inspector want 100mm depth of something/anything or a decent u rating????
Also how do I measure the roof space, I now have a large dormer. Not sure how to calculate the square metre.
How far down do I go with the insulation - it would seem sensible to go past the upstands to the floor but I noticed another post said not to...
Can you advise on good price and place to purchase what ever insulation you would reccomend
Many thanks in advance
