Luxury Aluminium Floating Corner or Curved Bi-fold Doors

KAT Aluminium Floating Corner or Curved Bi-folding Doors

...

Whatever your vision might be, our team can bring it to life beautifully, smoothly and seamlessly, from planning to completion. For uninterrupted views to two sides of your home, we can work together to design a corner bifold, either with a fixed corner post or with a moving (floating) post.

If it’s the ‘wow’ factor you are looking for, have you considered a curved bifold?

With multiple opening configurations available and a contemporary square, slim profile, KAT Aluminium Bifolding Doors allow larger glass units to be used, maximising the amount of light entering your room.

Designed with unique finger-cushioning between each door sash, with a wide range of RAL colours available, they are ideal for almost any type of extension, renovation or self-build project, with each individual panel measuring up to 1.2m wide and up to 3m high for narrower panels.

Unique hardware
Unique panel catch can be fitted to top or bottom of sashes, to ensure traffic door cannot be released from the next panel when adjacent doors are folded up – reduces possibility of service calls.

Unique stacking clips fitted in the top track to hold odd number sets open, prevents the panels closing in the wind. Saves on installation time as previous way of correcting the stack was toeing and healing.

Hinges can be colour matched to the frame.
Additional features
Moveable corner posts creating clear open corners as well as facetted or curved sets to create a unique look.

Integrated tilt and turn panel within the folding doors to achieve generous ventilation whilst the doors remain closed and locked.

...

Aluminium is the perfect material for Bifolding Doors, because it allows for narrow, aesthetically pleasing frames, is extremely strong and very low maintenance. Our doors are high performing in tests against wind, water and air pressure. They come with an extended 10 year warranty and our simulations tests have shown that they have a life expectancy in excess of 25 years.

We fit a unique panel catch to the master door and stacking clips to the top track to hold the door sashes open, this prevents the doors from being blown closed in the wind. As an additional feature, an integrated tilt and turn panel can be fitted within the folding doors to achieve generous ventilation whilst the doors remain closed and locked.

Take a look in the gallery at some recent projects, including corner bifolds and curved bifold doors.

Integral venetian blinds, suitable for corner bifolds are made to fit neatly between 2 panes of glass, offering a contemporary look for Bifold Doors in a choice of 10 colours; White, Yellow, Hay, Sage, Sky, Cream, Putty, Silver, Dark Silver and Dark Grey.

Raising and lowering of the blinds is controlled using either a Rotational Wand, Rotational Knob or a Cord system. The blinds carry a 5 year guarantee, are maintenance free, conform to BSEN 13120 Safety Standards and are suitable for 28mm double glazed door sashes up to 1200mm wide.



Material Information

...

Aluminium offers incomparable thermal properties, seeing Bifold Doors made of the material commonly exceed efficiency standards.

All of our doors and windows meet standards specified by UK Test Institutes, for weather performance and high security.

Once powder coated, aluminium doors are corrosion and weather resistant, making them insusceptible to swelling and warping.

The slim, secure and strong nature of aluminium doors means a reduced amount is needed to support the glass and hardware, even when they are used on large-scale projects.
