Hi. I am looking for bifold doors for by new extension. I know there have been lots of threads on here but I am looking specifically at slimline ones (narrow sightlines?). Has anyone used sunseeker doors? I get the impression they may lurk on a few of the website forums so I was wondering if anyone has genuine experience of them. They seem to offer a good choice? Any advice for any slimline aluminium doors would be great. Thanks
