bi-FOLD Windows

Bi-fold doors can be an excellent way to completely transform your home, and provide it with an exceptional entrance to the beautiful garden area. These doors can help you create an inviting and open terrace-like feel to the home. Bi-fold doors can blur the line between your garden and home to provide you with a real holiday experience.

Although these doors are perfect for the summer season, it does not mean you have to compromise during the winter months. These doors are very energy efficient, and make sure your home is warm and cosy during the winter months while saving you money on your energy bills. With double glazed energy efficient materials, such as aluminium, hardwood or UPVC frames, you won’t have to worry about heat loss.

Slim uPVC & Aluminium Bifold Doors

Imagine upvc/aluminium bi-fold doors offer a cost-effective folding door solution whilst still providing slim sight lines when compared to many other upvc systems.

Manufactured using high quality profiles our bi-fold door provides slim sight-lines and wide panels which make them a very popular choice for new build and renovation installations where cost is an important factor.

Our doors feature a choice of 3 thresholds with stainless steel rollers fitted to both top and bottom of sliding panels which ensures a smooth, easy opening and closing operation. For peace of mind hinge fixings and rollers are concealed when the door is closed with ERA high security shoot bolt and hook bolt locking systems fitted as standard.

Slim Sightlines with wider glass

UPVC bifold doors are available with panels of up to 1 metre wide allowing natural light to flood into the room.

This kitchen extension has a 4 panel Imagine door with anthracite grey foil on the outside and white inside with wide panels for maximum unspoilt views of the garden. The traffic door on the left and the next panel are fitted with chrome handles for easy operation of the high security locking system.

Threshold options

There are 3 track options to choose from including a low threshold, rebated threshold for exposed locations and a room divider threshold which is only 15mm high offering the perfect solution for doors installed between the house and conservatory.

Energy Efficient 1.3 U-value

Our standard glazing is clear 28mm Argon gas filled Planitherm toughened double glazing which provides an overall 1.3 U-value.

Upgrades to 40mm triple glazing are also available that will increase the thermal efficiency of the door to an overall 1.0 U-value if required.

Solar control and self-cleaning glass are available at additional cost.

Optional Integrated Blinds

Integral blinds are a popular option with folding doors as they provide privacy and controllable shade from direct sunlight.

Available in a range of colours our venetian integral blinds are cord free and are controlled by magnetic sliding blocks on each side of the glass to raise, lower and tilt the blinds.

Extended Colour Range

upvc bifolding doors are available in standard white finish or a range of 30 different foiled wood grain finishes including traditional colours such as Rosewood and Light Oak, Green, Black, Anthracite Grey or white.

These superb wood grain finishes are available on the inside and outside of your door or you can specify a different colour on the inside making your door really bespoke to you. Note that some colours will require an extended lead time.
