Bi-folding doors meet the demands of contemporary living combined with beauty, function and form…

If you were to compile a list of spectacular home improvements there’s no doubt that bi-folding doors would sit somewhere near the top of the list as they’re one of the most sophisticated products on the market. They bear no comparison to any other door solution as they’re completely unique and have set the standard for future door designs to follow, a very high standard at that.

Anthracite Grey Bi-Folding Doors

Door panels are configured into a number of folds for greater versatility, which concertina into a small space, allowing optimum light and access into a room with minimal obstruction. Bi-Folding Doors allow for a wider opening from a house, orangery or conservatory – extending any home so owners can enjoy the benefits of the outdoors and their gardens all year round. Ideal in applications where an opening or partition is required between rooms, or where the home leads onto a patio outside area.

Bi-Fold Frame

Our Bi-Fold frames boast maximum warmth and security and slide effortlessly to the side to make the most of your space. You can even incorporate a discreet passenger door for everyday entry.

Bi-Fold hardware

Our Bi-Fold Door Handles come in a range of colours to suit your home, they’re built to last with robust materials and quality finishes.

Bi-Fold Easy Glide System

The sliding operation of a bi-folding door relies on a high-quality stainless-steel track on which quad rollers, which are fitted to the door leafs, glide along in elegant fashion. The same quad rollers are fitted with a small brush on one end to keep the tracks free of dust and dirt.

Bi-Fold Low Threshold

Low level thresholds increase the ease of access for everyone involved. An optional outer and inner ramp can be added on to the threshold to further enhance the accessibility for wheelchair users.

Security with style is a winning combination…

Our bi-folding doors are extremely safe due to a multi-point locking system which keeps them incredibly secure. Our customers are always confident that their home will remain safe while they’re away because once the door is closed it will stay soundly locked.

We employ advanced glazing technology into our doors which will keep your home as thermally efficient as possible. With our multi-point locking system combined with our state of the art glazing, you can be assured that our doors perform at their absolute best in terms of energy efficiency and security.

Our bi-folding doors come in an array of options…

Our bi-folding doors can be installed in a wide variety of colour finishes, sizes and configurations. Whether you want to create a grand entrance into your garden with a large panel bi-folding door, or if you simply wish to connect your conservatory or orangery to another room in your home, we have you covered.

Colour options for both contemporary or traditional styles…

We are thrilled to offer our customers a full catalogue of colour options that is sure to please every customer. With everything from deep colourful shades to gorgeous woodgrain finishes such as Oak, Walnut and Rosewood, there will be no shortage of choices. If you do not see your favourite, let us know and we can see if we can customise it for you!

If one option is not enough, then why not go for a dual-coloured finish! This means that there will be a different colour on the internal portion as opposed to the external portion and is sure to complement both areas of your home.

The finish is in the details…

Our team of expert craftspeople have worked tirelessly to seamlessly blend style and security into the handles designed to complement our bi-folding doors. At Permaframe, we offer traditional style handle designs as well as modern ones which are sure to impress everyone’s own personal needs.

It is important to note that inside a bi-bolding door there are two handles - one intermediate handle as well as a D-handle. The intermediate handle releases the folding panes from the door frame which allows the door to open. The D-handle is then used to pull or push the folding panes to their desired location.
