Background: It's a shared house, I used to live there but now in with the missus however I still pay all the bills & my furnishings remain inc. flat screen TVs etc. However the remaining occupants insist on opening the large bathroom window fully and leaving like that, when they are cold they turn the thermostat up to 35 (I guess concerns about your carbon footprint are directly related to whether you pay the bill for it) plus it lets rain pour in if the wind is blowing that way. It is also a security concern as it is over a flat roof below which you could climb onto from one of the garden chars and easily hop in through said window. Initially I put in the most powerful (and expensive) extractor fan possible and locked the window in the "trickle" position thinking this would provide adequate ventilation....this simply resulted in the lock being busted off twice.
Attempted solution: I tried fixing one of these https://www.ironmongerydirect.co.uk/product/light-duty-door-closer-silver-465901
thinking if I set it too its slowest speed it would close over a couple of minutes giving a decent amount of air circulation, and could just be pushed open again if more was required but once the room is unattended will close the window for thermal insulation and also the window will at least look closed and not attract attention.
The problem: It hasn't worked.... I mounted the closer following the transom instructions for door mounting, quite close to the hinge side. However where doors pivot around a single hinge point the casement windows have sliders. The closer is only effecting for the final 1/4 of the close. It doesn't seem to pull on the window before that point, or at least not hard enough. I was wondering if moving the closer away from the hinge side of of the frame to the side the window opens from would give it more leverage to work? I am asking here first for any advice as I already have more holes in the window frame than are strictly necessary and would like to avoid turning it into a sieve as I experiment with different options.
Or if there is any solutions I haven't thought of/alternative products please let me know!
