Bi-Folding Doors

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.

We don’t allow security to be an afterthought...

Within each bi-folding door from TradeMark is a multi-point locking system which helps to make the door supremely secure. It engages at several points, and in several directions, into a tough lock keep, to keep the door sash fixed firmly to the door frame.

Our bi-folding doors can be supplied in either a double or triple glazed unit, and the glass panes within each individual door leaf are remarkably tough and designed to resist removal from the outside. Cylinder locks are also housed inside of the high security master handles which should make an intruder think twice about attempting to force them open.

Once you have outlined what finishing touches you want for your aluminium bi-folding doors, we will then get on with designing and manufacturing the product, ahead of the final installation.

TradeMark has many configurations to meet your home’s requirements…

Every homeowner is unique in their wants and needs so we are happy to manufacture our collection of bi-folding doors in a variety of sizes and finishes. You may want bi-folding doors to connect two rooms, but commonly we install bi-folding doors with the goal of connecting the inside with the outside. Either is a great option.

You’re covered for colour – we have every sort of finish...

We don’t just offer you the chance of configuring your bi-folding doors in multiple ways. We also provide you with a cracking choice of colours. Our sublimated woodgrain finishes (Walnut, Rosewood and Oak) are frequently requested by customers, and there are also our powder-coated finishes to mull over. When torn between two different finishes, think about having a dual-coloured bi-fold to get the both of best worlds.

The handle makes a bi-folding simple to manoeuvre...

Depending on how your bi-folding door is configured, it will come with one of three different types of handles. A pass door and integrated French doors require a master handle where the cylinder lock will be housed to help the multi-point locking system engage when you close the bi-folding door.

Each door leaf will also need a D-handle and an intermediate handle. The role of the intermediate handle is to release the folding panes from the door frame when it’s being opened and to re-engage them when it’s being closed. The D-handle is for pushing and pulling the entirety of the door. Our hardware range includes an array of traditional and modern master handles, which you can colour match with the intermediate and D-handles.
