Ultra slim aluminium bifold doors with 30mm frames
The Sieger Lux Bifold Door is an ultra slim aluminium bifold system designed for projects where the folding doors need to open wide without heavy visible framing. With 30mm profile widths, structurally bonded glazing and thermally broken aluminium frames, it brings the flexibility of a bifold door into a far more minimal architectural design.
Each panel can be manufactured up to 3m high and 1.2m wide, with inward or outward opening configurations, bi-parting layouts, opening corners and pass doors available. This makes the system ideal for premium homes, extensions, commercial spaces and architect-led projects where clear views, open apertures and refined detailing are central to the brief.
Sieger Systems supplies and installs ultra slim aluminium bifold doors across London, Buckinghamshire, Berkshire, Oxfordshire, Hertfordshire, Surrey, Bath, Bristol and Somerset.
