Q: What is the difference between bifold and sliding patio doors?
A: Bifold doors fold and stack completely to one or both sides, opening the entire space. Sliding doors only open partially—typically 50% of the opening remains blocked.
Q: How many panels can be installed?
A: We typically configure 2–8 panels depending on your opening size and stacking preferences. Larger openings benefit from more panels for balanced operation.
Q: Is it suitable for exterior use?
A: Absolutely. These bifold systems are specifically designed for patio and outdoor applications with full weather sealing and durable UPVC construction.
Q: Can I customize the color?
A: Yes. Choose from white, wood grain finishes, matte options, or specify any RAL color to match your project aesthetic.
Q: What glass thickness do you recommend?
A: For standard residential applications, 20–24mm double glazing provides excellent performance. Consider 28mm triple glazing for maximum insulation in extreme climates.
