Bifolding Doors

Our stunning bifolding doors turn outside space into another usable room for your home or business..

On a warm summer’s day, these stunning doors allow you to fold up the entire glass wall and turn your garden into another spacious room for you and your guests to enjoy. Or on a cold winter’s evening, enjoy the magnificent view of your snowy garden, glistening in the moonlight whilst you stay warm and cosy inside.

Bespoke aluminium bifolding doors offer a modern and stylish way to open up your home…no wonder they regularly appear on Channel 4´s Grand Designs!

Available in a multitude of different configurations, tailored to suit your property and your needs, our doors offer the perfect solution for living rooms, kitchen dining areas, conservatories, pool rooms and balconies to offer space, increased natural light and flexibility to your living space.

Available in a range of popular colours, 4 woodgrain designs, or over 150 bespoke colours to make a statement, or simply match the colours in your home.

Thermally efficient, with Planitherm “A” rated glass, our doors will keep you cool in the summer, and warm in the winter, and conform to the British Weather Rating standard of BS6375. So you can be stylish and keep your energy bills low.

Peace of Mind

Our beautiful bespoke bifolding doors come with a 20 year manufacturer’s warranty which is unrivalled in the industry, together with a unique 8 point multi-locking system which conforms to the Police preferred “Secured by Design” standards and locking cylinder which protects against snapping, picking drilling and “bumping”.

Our doors come with a bespoke “finger safe” gasket, ensuring that there is no gap for little fingers to get trapped in, and the lead door is prevented from slamming by a strong magnetic stay which holds the door in place. Low thresholds allow for equal floor finishes inside and out.

"I had 5 new double glazed windows and a new back door fitted. Andy, who came to do the pricing and the survey was very knowledgeable and took the time to listen to any of my queries, and also advised on window designs for some of the rooms, which we went with. There were no hard sales tactics. I received my quote within two hours of Andy leaving, and it was left with me to contact him. The work was exceptional, the guys who came and did the work were courteous and kept me up to date with everything along the way. They left the rooms spotless! Best priced company! Would recommend to anyone! "

- Mr K – High Wycombe

"Andy was a pleasure to deal with - very knowledgeable and made valuable observations about the best configurations for each room. The cost of the windows was also very reasonable compared to 3 other companies that also quoted. The installation team did a great job - turned up on time, were neat and tidy and the work was completed within the quoted 5 days. The whole experience was hassle-free from start to finish. Everything is communicated and clearly stated from the start. I would highly recommend APS Window Company "

- Mrs A – Beaconsfield

"All of the team at APS Windows were brilliant - from responding to our initial queries, through to the survey and fitting. They were always quick to respond to any questions, and clearly confirm details with us. Andy, who came out for the initial visit and then complete survey, was brilliant, and really took time to talk through options with us. Our fitting team, Matt and Miles, always arrived on time, and did an excellent job of fitting, including clearing up at the end of every day. We are very happy with the quality of our windows and doors, and would certainly recommend APS to any one. "

- Mrs K – Amersham

"The APS team are punctual, friendly, and very professional. The 2 guys that came to fit the doors and windows were fabulous. The workmanship is to a high standard, they just got on with the job and totally delivered on the project with minimum disruption to a high standard on agreed budget. Can’t recommend them enough! Great job. Great company."

- Mrs B - Marlow

"I do not normally give 100 percent but to have people in your home that were polite, professional, clean and tidy and just did their job with no fuss was an absolute treat. As I was dreading the mess and there was not any"

- Mrs R - Watford

APS Windows have done an excellent job, with great attention to detail, and were always very courteous. I would have no hesitation in recommending them.

--Mr & Mrs E. Holmer Green

The windows were installed on time and to specification, and the surrounding area made good. One window was faulty, and was replaced with no fuss and at no inconvenience to us. We would use this company again and would recommend them to others.

--Ms B. Northwood

Very positive experience with APS Window Company: quick to give an estimated cost, very easy to talk to, efficient service and an excellent installation. The finish on the installation is perfect and everything on the windowsill was put back as it was found.

--Mrs A. Beaconsfield

APS Windows are superb, I would definitely recommend this company to everyone and would certainly use them again in the future. This type of 1st class service is not the "norm" these days but its great to see such companies do still exist.

--Mrs T. Marlow

Very courteous and efficient. Excellent workmanship and had no worries in leaving them in our house whilst we were out. Would be happy to recommend to anyone.

--Mr & Mrs M, Croxley Green

Firstly I would just like to say what a nice company you are to deal with, no pressure on the sales side, installation time was agreed and even turned up when you were supposed to, very clean and tidy workmanship. First class job, would highly recommend you. To anyone that may read this they are genuinely nice people.
