Doesn't Fensa/certass now say for any 1st window accessible via flat roof, conservatory roof, pitched tiled roof has to have safety glass in case a burglar cuts him/herself on float glass when they break in, so as well as all groundfloor units to have laminate outer pane I'd also spec the same for units within windows that are accessible

Document Q only applies to new build houses and extensions not renovations/replacements. Plus as far as I am aware conservatories are still building regs free (unless over a certain size) so not required there either.

Gazman,
I assumed that most people esp burglars knew that you smash the corner of toughened glass to make the whole thing collapse into piece. Not sure how loud it is when that happens, maybe very?

Quite quite actually. The pop dosent make any noise really only the glass landing on the ground. If its onto grass or a dust sheet or something thats quite quite too.

Of course, we should think and gave consideration to the burglar and spend on them so that they dont hurt themselves. This is the UK afterall.

Why does the glass reference change from Pxx to BRx?
