AluK Doors
...redefine the standards of elegance
At Kayvex Windows, we’re pleased to offer Littlehampton and West Sussex homeowners a striking, practical way to open up their living space with our AluK aluminium bifold doors. Built to blur the line between garden and living room, they’re designed to lift the look of your home while genuinely improving how it works day to day, more daylight, more room to breathe, and the security and efficiency your household needs.
Aluminium Bifold Doors
Get Your Free QuoteOur AluK aluminium bifold doors are a natural fit for any Littlehampton or West Sussex home looking to bring the garden and living space together. Folded back, the panels stack neatly to one side, opening up the full width of the aperture so there’s nothing standing between your kitchen or lounge and the outside. Built from premium-grade aluminium, they combine everyday durability with genuinely strong thermal performance, so the room stays comfortable whatever the season. With a broad choice of finishes and configurations, we’ll help you find a set-up that suits both your home’s style and how you actually plan to use the space, compare against our French doors and patio doors ranges if you’re still deciding on the right opening for your project.
Premium, High Quality Doors
Every Littlehampton and West Sussex property has its own character, and we don’t expect one bifold configuration to suit them all. Choose from a range of panel counts, opening directions, and frame styles, whether you want something understated for a period home or a bolder, more contemporary look. Colours and finishes are fully customisable too, so your new doors sit comfortably alongside your existing brickwork, render or trim rather than looking bolted on.
Energy Efficiency
Our AluK bifold doors are engineered with genuine thermal performance in mind, not just as an afterthought. A concealed thermal break running through each frame limits how much heat can transfer through the aluminium, helping your room hold its temperature whether it’s a cold snap in January or a heatwave in August. The result is less strain on your heating and cooling, and a more even, comfortable room throughout the year.
Built to Last
Aluminium is at the core of why these doors perform the way they do. High-grade frames stand up to the coastal weather that West Sussex properties see regularly, without warping, corroding or fading the way some materials can over time. That means the doors keep working smoothly and looking sharp for years, with very little upkeep required beyond an occasional wipe down, a genuinely low-maintenance investment for busy households.
Paired with double glazing options and properly sealed frames, our AluK bifold doors also do a strong job of holding heat in and keeping draughts out, cutting down on energy loss and helping keep your home a bit greener as well as more comfortable.

Frequently Asked Questions (FAQs)
How much space do bifold doors need to open?
Bifold panels stack neatly to one side of the aperture, so unlike a traditional French or patio door, they need very little extra room, most of the folded stack sits within the width of the opening itself.
Are AluK bifold doors thermally efficient?
Yes, each frame includes a concealed thermal break to limit heat transfer, and can be paired with our double glazing or triple glazing for even stronger performance.
Can I choose how many panels my bifold door has?
Yes, panel configurations are fully customisable to suit the width of your opening and how you plan to use the space, whether that’s a compact 2-panel set or a wider multi-panel run.
Are AluK doors secure?
Yes, our AluK doors come with multi-point locking as standard, giving you a strong, secure barrier alongside the doors’ natural strength as an aluminium product.
How long is the guarantee on AluK doors?
Our AluK doors come with a guarantee of up to 10 years, so you can rely on their performance for years to come.
Happy Customers
Alison Lowe
Kayvex has replaced several windows in my home and fitted a new door. The service provided was fantastic.. all the staff were efficient, polite, professional and did a superb job. The cost was reasonable, and at all times, I was kept informed of the progress of the jobs undertaken. An excellent company to deal with.
Clare Taylor
I am very happy with my new porch door. It is very well made and has been fitted very well. It was a new fit rather than a replacement door. The fitters were extremely tidy, polite and conscientious. Leaving everywhere very tidy. They even bought their own hoover. The price was very reasonable compared with other quotes. No pushy salesman either. I would use it again as and when the need arises.
Julie
We had our patio door fitted yesterday and felt I needed to leave a review, as this experience was one of the best we have ever had. The price was fantastic, the salesman George was professional, efficient and not pushy at all. The surveyor was nice too; the fitters were brilliant, every appointment was precisely on time, the paperwork was emailed when they said it would be, and the payments required were staged, with the final payment due once fitted and happy.
The door is perfect; it was 6 weeks from start to finish despite being quoted 12 weeks (which we were happy with). I would not hesitate to recommend Kayvex to anyone, it all seemed a bit too good to be true quite honestly. Well done, Kayvex.
Helen Elliott-Adams
From Sales to the installation of our “Warm Roof”, we could not fault the service we received. Everyone we came into contact with was excellent. Nothing was too much trouble for our installation team. We would not hesitate to use Kayvex again or to recommend them.
Stephen Jordan
A neighbour recommended us Kayvex. From start to finish we received a very good service, John visited and offered very good advice on the products we required. Shelley and Tia were always available to answer any enquiries, and Wayne was also very informative when carrying out the survey, talking us through the fitting process and talking in detail about the products we were purchasing.
We had doors and windows fitted, and Paul and Brandon carried out the fitting. They arrived on time each day, were friendly in their approach, and carried out the fitting to a high standard whilst being respectful of our home with their tidiness.
We found all the members of the team friendly and knowledgeable and would recommend Kayvex to anyone having door and window home improvements.
