We have old knackered single glazed patio doors that we want to replace but not sure what to replace them with. French doors (where two doors open out)) would seem to block a lot of visibility/light from what’s there now and sliding seem rather old fashioned. Bifolds are lovely but are they massively more expensive? Are there any downsides to them?
The door space seems non-standard so it’s difficult to look up eg Wickes and compare prices as there’s nothing the same.
