Features & Benefits

Over the years bi-folding doors have become a lot slimmer and less conspicuous. Thanks to innovation in the materials used, the frames today are smaller, yet still very strong.And because the doors fold, they take a lot less space when opened. This allows them to open up an entire wall, which isn’t really possible with sliding patio doors. The doors neatly fold away to the edge of the frame. Your home will benefit from maximum visibility and unmatched convenient garden access.

Due to their slim frame profile, the window surface is a lot larger, meaning they allow far more light into the room than any other window or door. Even when closed there’s little in the way of light, so there isn’t really a compromise. And obviously when opened the space is astounding, with nothing obstructing natural daylight. Bi-folding doors can be perfect for rooms that don’t get much light, rooms which you’d like to enjoy more time in.

Although bi-folds may seem fragile and not very strong due to the fact they literally replace a brick wall with glass, they are very secure. So much so, that bi-folds are widely used by businesses in commercial environments. The security elements which they have include multi-point locks, robust frames secure with heavy duty hinges, and in some cases, laminated triple glazed glass. The glass is tougher to break and the doors can’t be levered off the hinges. All that makes break ins very difficult and is likely to put off burglars.

It’s always nice to know that your home increase in value over time, even if you don’t plan on selling it. It’s certainly something to consider when planning your next home renovation project. Bi-folding doors can fit any style house, from old Victorian homes to modern, even minimal, home styles that have become so popular these days. Their simplicity and practicality can enhance the way you live at home. Bi-folding doors brighten up dark spaces and create seamless access to your garden, blending the inside with the outside.

Bi-folding doors, especially the ones made of aluminium, can withstand temperature changes throughout the year. Neither the cold nor the hot weather can warp or bend the frames. Bi-folding doors are highly thermally efficient and can withstand strong gust of wind as well. And all that doesn’t come at a cost, because folding doors are easy to maintain. Their lifespan can be prolonged by just simple occasional wash down and a dash of oil.
