Contact Our Team TodayWhat are bi-fold doors and how do they work?
Bi-fold doors are a type of door that is made up of multiple panels that fold in on themselves when opened. They work by using hinges and a track system to allow the panels to smoothly fold and slide to one side, creating a wide opening and maximising space.
Can I install bi-fold doors in an existing opening?
Yes, our expert team can assess your existing space and determine the feasibility of installing bi-fold doors, ensuring a seamless and hassle-free installation.
Are bi-fold doors secure?
Absolutely! Our bi-fold doors are designed with robust locking systems and toughened glass where required, providing maximum security for your peace of mind.
How do I maintain and clean my bi-fold doors?
Cleaning and maintaining your bi-fold doors is simple. Regularly wipe down the frames with a mild detergent and clean the glazing panels with a non-abrasive glass cleaner for a sparkling shine.
What are the differences between uPVC bi-folds and aluminium bi-folds?
While both uPVC and aluminium bi-fold doors offer their own unique advantages, there are key differences to consider. uPVC bi-fold doors are generally more cost-effective, low-maintenance, and offer better thermal insulation. On the other hand, aluminium bi-fold doors are known for their sleek design, excellent strength and durability, larger glass panels, and a wider range of finish options. Ultimately, the choice depends on your priorities in terms of aesthetics, budget, and performance. Our expert team can help you determine the best option for your specific needs.
