I went for two fixed windows and am (currently) glad I did - they look great from the inside and out, can’t leak and as there’ll seldom be anyone in the back, think it was the right compromise.What happened in the end ? What did you go for ?
My converter said it’d only be £50 plus the cost of the new window if I wanted to switch, so I’d rather pay for something I know I’ll use in the future, if I find I need sliders.
