WOW the Indows are amazing - we have a 1925 Spanish revival home with 37 original casement windows. The windows were extensively rehabbed inside and out by a prior owner and are in fabulous condition - but of course they are only single panes. We just received an initial order of six Indows to see if we like them and we are just blown away by the difference they have made in these three rooms. Yes it can be a little tricky to get them delivered to your house from the freight warehouse (especially here in the NY metro area) but that is not the fault of Indow. They all fit perfectly and honestly you don't even know they are there! The prior owners also installed pull down screens using an interior metal frame - so the Indows fit perfectly against those frames. Just super happy with the Indows and I know for certain we will be ordering more of them!
