The building inspector has asked us to switch our normal friction hinges for emergency egress hinges on our side hung UPVC windows. I've measured them and the hinges are 12 inches long.
Everyone tells me they are easy to fit, but I'm not sure how to go about it; will I need to take the window out completely? If I do have to take it out, how do I not drop it down through the conservatory roof?
I'd be grateful for any words of wisdom.
