Got a bit of a problem with the double glazing – whenever the North wind blows (like it is at the mo) any gusts make the windows howl like a bad ghost film sound effect. It’s coming from somewhere around the external side of the frame rather than around any of the windows themselves, but as its the upstairs windows with no easy access for a ladder I’ve not had a chance for a proper look.
The sound is a bit like the noise you got as a kid by sticking a blade of grass between your thumbs and blowing so I’m guessing that somethings vibrating in there, but of course when I get a chance to take a look the wind won’t be blowing so I’ll be none the wiser until the next time I got woken up by the ghoulies…
Any ideas?
