Doing a side kitchen extension and will be ordering windows and doors soon. Will need a couple of small UPVc windows and 2 sets of 1800mm French doors.
What's the deal with trickle vents in the windows and doors? I know what they do but are they any use and are they a requirement for BC? Do they need to be on both windows and French doors? To me they spoil the clean lines of a window, particularly the small ones.
