Had Magentite over to quote up 3 windows, which came in at a STUPIDLY priced figure in the thousands. No idea how they can charge that for some frames and perspex but anyway! Are there any other solutions , mainly to cut down cold/hot heat transfer but specifically noise? Road noise is quite bad and we want to minimise this in our bedroom Any suggestions guys/girls? The windows are sash windows. Thanks Kris
