Recently had some Cortizo aluminium sliding doors fitted into what was previously windows (by a local company, Certass cert) and wanted a 'matching' aluminium window for the same room but found their pricing ridiculous. Found a 'supply only' to public for a sensible price and went for it (surveyed myself, they didn't offer anyway).
Anyway, measured to maximise the frame height externally (which would entail chipping off some old render previously cloaked over) and ordered the window having at the last minute decided to tick the trickle vent box 'just to be sure' I wouldn't have any issues when I get this and some other planned DIY windows signed off. On this window the single vent is in a 20mm aluminium add-on, which I now find will foul the very thick render/plaster reveal on the inside. My bad of course, but hoping for some help in getting out of it!
Seem to have a few options...
1) As I'm reinstating a course of bricks where some creasing tiles were, I can lower the window a bit to allow the vent not to foul, but prefer not to as that results in wide cloaking on top of the add-on, which just looks ugly in my opinion. The window is short in height already compared to modern window sizes.
2) Take off all the 1" thick render/plaster (hard as concrete) on the reveal/replace with thinner - definitely not an option!
3) Blank off the inner vent and fill void with silicone (a go-to solution for some after reading on here). Doesn't help if regs demand venting***
4) Chisel out a recess in the plaster to allow the vent to sit within it, make good around it (or is there an in-plaster vent I could replace it with?). This is my preferred option but a bit concerned about cold/damp against the plaster, am I asking for problems? Or leave that recess squared off with a bit of air around it? Not too worried about aesthetics - in fact it could actually look better; I don't really like the sight of vents on the face anyway...
***Existing windows did not have trickle vents. Room is a re-sited kitchen with external extraction and the sliding doors have integral vents (not sure of EA, been trying to find out). Does this mean BR can't insist on a vent on this window if I resort to option 3? I'd prefer the ability to vent though, via option 4.
Any suggestions appreciated, thanks.
