uPVC Bi-Fold Doors

uPVC bi-fold doors consist of a multi-leafed door design that folds neatly away upon opening, allowing you to enjoy a completely seamless connection to your garden or property interior. They stand as a truly modern choice for any home.

All of our uPVC bi-fold doors operate on a high performance rolling system, that allows for complete ease of use. This innovative system effectively offsets the weight of the sash, meaning you won’t have to struggle when opening the door.

All of our uPVC bi-fold doors feature the unrivalled uPVC profile from Liniar. This door system is 100% recyclable and 100% lead-free, meaning you can enjoy leading standards of heat retention, security and durability with peace of mind.

Features & Benefits

The seamless connection inherent to the bi-fold door design can be further enhanced with ultra-low thresholds, which allows for easy accessibility for both wheelchair and pushchair users. This means that all friends and families can benefit.

With the 90% of the door aperture becoming free once our bi-fold doors are fully opened, you’ll be able to enjoy completely unrestricted views and unobstructed ventilation. This means that you’ll be able to bring a bright and spacious feel to any room.

Our bi-fold doors can be expertly tailored to match the style and space of your home, meaning your doors are sure to fit perfectly. This not only guarantees that your home aesthetic will be maintained, it will also ensure your doors perform as they are designed to do.

All the intelligently designed hardware is intelligently concealed into the frame to maintain a clean and crisp finish. This also has a security benefit, as concealed locking systems and hinges are incredibly difficult to reach to use as a leverage point.

uPVC is an inherently low maintenance material, meaning it requires very little upkeep in order to maintain a clean and crisp appearance. All you will need to do is wipe the doors down with a damp cloth to maintain an ‘as new’ look.

These uPVC bi-fold doors are manufactured using an inherently strong and secure uPVC profile, allowing them to offer impressive home security from the ground up. This factor is then enhanced with high security, multi-point locking systems to maintain a consistent standard.
