floor insulation in a residential barn conversion

Postby jamezevani » Sun Jun 24, 2007 1:54 pm

i have just bought a abrn with planning permission to convert to residential.
I am discussing with the builder ways of getting the floor insulated to meet b reg standards.
he is saying to me the only was is to dig out the existing concrete floor and put in the insulation and bring back the level to simlar as it is now. Obviously this involves a lot of digging out, the floor measures 11m by 7m.
Does anybody know of the cheapest/ most effecient way to meet the b-regs stadanrds?
I do not really want to increase the floor level signicantly over it now.
Another question concerns a block built outbuilding that the planners forgot to tell me to demolish - it can link into the house, it is single block and i can do the internall insulation and again it looks as if im going to have to dig out the floor, the roof pitch is very modest and the builder says i need to increase this to accommodate a pitched roof, at present the roof has all the joists and support a corrguated roof, it would be a lot wasier to keep the same pitch as present, so i can sort out myself, is there ny suitble roofing material that would enable me to do this?

Simply Build It

Hi james, its a pig but I had to dig the floors out using a breaker and a wheelbarrow. Upside is that you can ensure that any waterproofing you do is thorough.
I'm just about to re-point below ground level on the internal walls followed by a scratch coat on which I will use then Thoroseal. I'm not to far ahead of you so would be great to share knowledge.
I'll keep an eye on this area but you ca also get me on pcfglimited@aol.com

i ihave come to the conclusion that is what i am going to have to do, its going to be a pig of a job but would lso be benefitial as it give me the opportunity to lower the ground level, which would enable a doorway out the front, at he moment the floor level is two blocks higher thn the existing openings. i will send some pictures over to you via the e-mail. my e-mail is jamezevani@tiscali.co.uk

I have a stone barn still awaiting planning concent & conversion to domectic dwelling. I have noticed your comments on thermal requierments for flooring & would be interested in hearing what you've done to comply with b'regs re floor spec's. what type of insulation has been put in, thickness etc. how far on any of you are with your conversions & what problems you have had to overcome so far?
