Are bi-fold doors energy-efficient?
Yes, modern bi-fold doors are designed with energy efficiency in mind. They typically come with double or triple glazing and high-quality seals to minimise heat loss, helping keep your home warm and reducing energy bills.
Do bi-fold doors provide enough security?
Absolutely. Bi-fold doors are fitted with advanced locking systems, including multi-point locks and toughened glass, which make them secure. Look for bi-fold doors that meet British security standards for extra peace of mind.
How much space do bi-fold doors take up?
Bi-fold doors are space-saving by design, as they fold neatly against the wall when opened. This allows you to maximise your indoor and outdoor space, making them ideal for compact areas or for creating an open-plan effect.
Are bi-fold doors difficult to maintain?
Bi-fold doors are generally low maintenance. The aluminium or uPVC frames are weather-resistant and won’t rust, warp, or rot. Regular cleaning of the glass and wiping down the frames with a damp cloth will keep them in great condition.
Can I customise bi-fold doors to suit my home’s design?
Yes, bi-fold doors are highly customisable. You can choose from various colours, frame materials, glazing options, and configurations to match your home’s style and needs.
