We’re building an extension to the house and intend to fit bifold doors in a 5 meter aperture. My partner has mobility problems, so they need to be as easy as possible to move. We’ve seen Origin Bifold doors which were ok, but we preferred Solarlux. The Solarlux seemed better made and were easier to open and close. They are more expensive though. Has anyone any experience of either, in terms of weatherproofing and durability?
