Stellar bifold saves about an hour to fit based on a three pane bifold door. Best door I have ever fitted. Because there are no gaskets to install, it’s a much quicker job.
Because the beads are pre-gasketed you don’t have to install a separate gasket which is fiddly and hurts your thumbs – plus the metal gets hot in the summer months which is awkward and horrible job to do. Also the pre-gasketed beads removes gasket shrinkage which is a problem with other aluminium doors.
Stellar is the innovative, new aluminium system that sets new standards. It revolutionises aluminium windows with its unique reverse butt joint. It's faster to fabricate, saves materials, and reduces stockholding. It's adaptable, attractive, simple to install, and maintenance requirements are minimal.
