    My house does not generally suffer from over heating as the large south facing windows have balconies above them allowing solar gain in the winter but are shaded in the summer. However I have 2 West facing inward opening windows each 1.2 X1.2 Metres. these do cause evening overheating and also get heavily battered by westerly storms in the winter.
    I am thinking of fitting external shutters to them hopefully to mitigate both problems. My thoughts are towards Louvre type to allow some light in and fresh air.
    Please can people advise on suppliers, fitters etc Area South East Wales

    Sounds like a good solution. An alternative that we have found sufficient is to fit a flyscreen over the outside of the window. It blocks enough of the light to make the difference for us, can be left permanently in place, and keeps the flies out :)

    But we do take them down in winter, so maybe a rigid shutter is a better idea if you're exposed to westerly storms.

    I have black Phifer SunTex 80 on removable screens that I usually put up in mid-April and remove the start of October and it makes a huge difference to afternoon overheating.

    It is a lot more restrictive than regular fly-screen or even pet/fibreglass mesh though, and as a result in the late spring and early autumn months, it can give the impression of overcast days even when the sun is shining, which is a little gloomy (which I haven't found to be an issue in houses with standard steel/aluminium flyscreen mesh)

    I have roller shutters and they roll right down for blackout but can be lifted a bit and lots of light comes in through little slots.

    I would advise against the louvre ones as they will get damaged by wind and are noisy, roller shutters get a big yes.

    Not many appreciate the dangers posed by west facing windows in relation to overheating.

    I considered roller shutters when I built but two factors based on my limited previous experience decided me against them:
    (1) The roller box is a big, ugly protuberance on the outside of the wall unless you can somehow come up with a solution that doesn't compromise the insulation. I couldn't.
    (2) To open or close the blind you either have to go outside, or you need a penentration through the outside wall, either for the roller tapes I had previous experience of, or for an electrical connection (to the ethically dubious electrical motor). Given my PH target, I'd already accepted no electrical sockets or switches on the outside walls.

    I'm curious how you overcame those issues?

    Thanks. How did you insulate the bits where the shutter boxes are?

    Sheet insulation (PIR) inboard f/g quilt outboard inside the cavity tray.
