FAQs
Find answers to some of the most common questions about our aluminium bifold doors.
What are the benefits of aluminium bifold doors?
Aluminium bifold doors create a wide connection between indoor and outdoor spaces while maximising natural light. Their slim frames provide larger areas of glass without compromising strength or thermal performance. They are also durable, low maintenance and available in bespoke configurations to suit different properties and opening sizes.
Are aluminium bifold doors secure?
Yes. Aluminium bifold doors can incorporate multipoint locking, reinforced frames, secure glazing and PAS 24 compliant security options. The exact security specification will depend on the chosen system and project requirements. Professional installation is also essential for ensuring the doors operate correctly and provide the intended level of protection.
How wide can bifold doors be?
The overall width of a bifold door installation depends on the system, panel dimensions and number of door leaves. Individual panels can be manufactured up to approximately 1,500mm wide and 3,000mm high with selected systems. Larger openings can be accommodated by combining multiple panels in a suitable configuration.
What maintenance do aluminium bifold doors need?
Aluminium bifold doors require relatively little maintenance. Frames and glass should be cleaned regularly using mild soapy water, while tracks should be kept clear of dirt and debris. Hinges, handles, locks, drainage channels and weather seals should also be inspected periodically to maintain smooth operation and reliable performance.
What is the lead time for bifold doors?
Lead times vary depending on the selected system, dimensions, configuration, glazing specification, finish and installation requirements. Bespoke bifold doors typically require detailed design, a site survey and precision manufacturing before installation. A confirmed programme can be provided once the final specification and site conditions have been assessed.
Do you offer bifold door installation?
Yes. Sieger Systems provides a complete design, supply and installation service. The process includes consultation, system specification, an accurate site survey, precision manufacturing and installation by an experienced team. This ensures the bifold doors are correctly measured, aligned, sealed and tested for dependable long-term performance.
