Whole House Luxury Made Easy!
Easy Installation –
The ALUNA bifold system has been designed to be quick and easy to install. The system offers an optional adjustable jamb feature for maximum adjustability of +/- 4mm either side during installation and is easily managed with an allen key.
Floating Corner Post –
The floating corner post option enables right-angled BF73 bifolding doors, including the return, to open out fully, with the option of a fixed corner for the
ultimate wow factor! (Structural support needs to be in place.)
Weather Resistance –
Excellent weather sealing is achieved using specially designed perimeter seals, with the option of weather piles for lower thresholds. The weather-tightness has been tested to British standards.
Low Maintenance –
Our low-maintenance aluminium doors are strong, durable and corrosion-resistant. Unlike timber, they don’t need painting or staining to keep them weatherproof, and they won’t rust or corrode. They will also never rot, peel or flake.
