Building regs and joist end caps

[SJRSJR]

Posted this in lofts section but it's relevant here too:

We're in a house that has had part of the loft converted by the previous owners (BC approved). There is a further space that has been started but not finished. I might not even need planning permission as it falls within the overall cubic metre allowance.

I've been looking at building regs and span tables and the joist size and strutting seems to be right but the joists don't have end caps on them into the external wall. I'm wondering if that would be a problem for building control as it would be too big a job to retrofit. Thanks.

Don't know what end caps are?
Any pics?

Do you mean when the ends of the joists are sleeved with some dpm?

Yes, they look like this. I can't retrofit them so can I do anything else that would do the job? It's to prevent air leakage/timber shrinkage.

You're worrying too much, BC won't give a hoot about such things in a lofty. I've never seen them used or specified them for a loft or had my spec questioned by BC.

Thanks, much appreciated!

Marketing con-trick. Would be more use as building blocks in a kiddy's play pen.

Tony ,
They are a slightly different design to what you old Manchester boys wear when you go the the working mans club.

Introduced approx 12 years ago and were strongly punted by NHBC to stop heat loss and draughts round joist ends built into inner cavity wall. Never caught on, never made mandatory, but we still mastic round joist ends to comply. If and that is if, we were buiding a one brick wall with joists in, then we would consider there use.
Cooked, served on silver platter and ready to be eaten.
