we completed a large job recently with hardwood windows instead of the usual pvcrap
anyway today was final day ,the day the bco signs the job off and we get our final payment
out of the blue he asks why the windows are not set 30mm into the cavity
me ,the old fella,the chippies,the window fitters ,even the client's cat didnt have the foggiest what he was on about??
apparently since 2002 all windows in new build have to lap the cavity by 30 mm
anyone else heard about this?
first time it has been mentioned and it is gonna cost us a grand+ to get the windows taken out and refitted then re plastered and redecorated
it just seems nuts that none of us had heard about this supposed rule
any advice gratefully received

ask the building inspector to show the change in the spec in 2002 because I have never heard of it and nothing shows up at google for that same search phrase

Sounds like a man justifying his job, those that havn`t been laid off from the BCO offices are all over everything around here. The HSE are even worse with so few sites to watch over they are everywhere.

spoke to his boss and he says it exists,spoke to the top man in a different office and he said he knows about it but they dont enforce it because its pointless
i will dig out a picture

ps my mate (a builder) got out of the extension game because of stuff like this,he just does a drive or so a week,less money but loads less grief

wow I am shocked LLL
I built a very large extension 2 years ago with 16 windows and 3 pair of french doors and side panels, fitted them as you normally would and it was passed off without any comment from the inspector
all I found at google was a pdf file from the nhbc website relating to standard procedures for new build but nothing relating to having the windows set 30mm into the cavity

well i am sure that you like us mick always fit the window so the back of the window lines up with the back of the outside skin of brickwork/blockwork,
we have to use this dermobate cavity closer now and it even has a little rubber flange for the window to sit against.
what he said was we have to fit the window from inside and push the window through the rubber flange to make an air tight seal
its just what you dont need just before xmas on a completely finished job
where can you view building regs online pls mick?
regards LLL

For a new build, would that type of detail be on the architect's drawing?
If not and if it has been built to the drawing which has been approved by the council, can you use this in your defense?

its an extension,the reveal is fine on the existing 225mm brwk just not on our new cavity stuff
its gonna look cat ,windows set at different reveals
but the BCOs dont think in the real world at times
regards LLL
ignorance is no defence apparently,even though this rule has been in place for 7 years i have yet to find 1 bod that knows about it
going out now

its called the planning portal but has info on building regs too
http://www.planningportal.gov.uk/england....pproval
Since 1 April 2002 building regulations have applied to all replacement glazing. The regulations apply to thermal performance and other areas such as safety, air supply, means of escape and ventilation
http://www.planningportal.gov.uk/england....rwindow
which we all know anyway.....well if not you should 
Approved Document F includes the guidance that all replacement windows should be fitted with trickle ventilators from 1 October 2006
http://www.planningportal.gov.uk/england....windows
and we all know this one too
The Building Act 1984 and Building Regulations: Legislation
http://www.communities.gov.uk/plannin....dingact
Laid before Parliament 5th March 2002
http://www.opsi.gov.uk/si/si2002/20020440.htm
25th November 2002
http://www.opsi.gov.uk/si/si2002/20022872.htm
i can't see anything relating to the position of the windows, maybe I have missed it, could someone else please check
cheers

I would ask building control to show you the reg. he is trying to apply and ask why building regs. did not specify it? then go back to the designer and ask his opinion on it before spending the money on it, MSH

I'm not sure if this site has the answer but I put it up anyway as it gives good advice on glazing.http://www.thewindowman.co.uk/

nothing regarding the position of the windows just conserving energy and safety
http://www.direct.gov.uk/en....0014147
work should comply with the requirements of part L and N of schedule 1 of the Building Regulations
Part L - Conservation of fuel and power
Part N - Glazing - safety in relation to impact, opening and cleaning
