thanks, Joists are 'I' beams, prob 9inch height but web thickness is pretty small - so the heat transfer through the joists must be minimal. There's suppposedly 9inch of rockwool between joists. Bedroom floor is chipboard and garage ceiling is 12mm plasterboard. I think this should add up to a...

long story. two issues; first the bedroom above garage is freezing. DWH said it will be "it's over the garage!". They drilled 50mm dia hole in garage ceiling pulled out a bit of rockwool and declared that it's fully insulated therefore its iaw ADL1A regs. I thought U-value requirement of all...

We have this problem. We live in a 12 mth old David Wilson Home called the Oakthorpe. Its a 4 bedroom, 3 ensuites, 'L' shaped house with main bedroom above double garage. Does anyone have this problem with same house type??!?!?!?!?!?! We've got claim in with NHBC but the more complainants the...

I thank you again D_Hailsham for your time and accuracy of answer...really helpful. I see I have a bit of a battle on with the builder who is clearly backpedalling, as he's put an S Plan Plus in smaller houses than ours on this development. I've started the resolution process with NHBC as well...

So builder visited our house. He says that house design was accepted by buildings inspector in Dec 2006, so 2006 regs are applicable. In summary he say's :- 1. On the floor area which is 161sqm total, he says usable area is only 145sqm as stairwell and cupboards aren't usable. Is that...

Many thanks for your help again, and for your patience...! I'll print the provisions off and find a darkened room to go study them. I used to think that building decent homes must be tough work; it's actually probably quite easy - it's making sense of the regulations that's the real killer...

sorry swbjackson....it was your comment on TRVs...!!!!!! Thanks!!

I do accept that system balance is likely to be a factor. I have considered trying to balance but when the input temp is 80degC, both sides of the rad is b****y hot to the touch - I'd benefit from having the right tools! Alec's comment about TRVs should be fitted to all but room stat rad (and...

Correction...there are 18 rads in the house...

Thanks again. I should have said that the house is a conventional 2 floors (but think you guessed that), 4 bedrooms upstairs. Thermostat is in the hallway, at the start of the stairwell. There are 15 rads in the house, 3 towel rails - one in each ensuite. 5 rads in the 4 bedrooms - it is only...

Many thanks for very rapid response. We moved into a new house in June 2011 in which foundations were laid in early 2011. The heating system was installed in April 2011. It only has a single heating zone and external wall-to-wall area is 161sqm ('usable' area might be less than 150sqm). We do...

In Bld Regs L1 2002 there is requirement that no heating zone is bigger than 150sqm. Could someone confirm if that requirement is still valid. 2002 is an old Reg and I can't find reference to the requirement in later versions. Also noticed on Honeywell & Drayton websites that new homes must now...
