Welcome to Surrey Design and Build

Folding Doors

At Surrey Design & Build we only install high quality specialist aluminium bi-folding doors. We maintain a high standard of quality control as all units are individually inspected before installation. All doors are installed by our specialist inhouse fitting team to ensure peace of mind.

Aluminium / UPVC What is the difference?

What many people do not realise is that UPVC Bi-folds expand in the heat much more than Aluminium Bi-folds. Generally speaking the maximum width for UPVC folding doors are around 4 metres for this very reason. Our Aluminium Bi-folds comfortably go up to 6 metres or more. Aluminium frames are extremely durable and won’t require any adjustments over time. Aluminium also has the advantage that it may be coloured any RAL colour. Also generally Aluminium doors are slimmer than UPVC due to Aluminium’s greater strength like-for-like, therefore we can maximise the glass area of the doors.

Choose from over 500 harmonious colours, ultra realistic wood effect finishes or even dual colour the doors for the ultimate individual touch. All doors are fitted with finger safe gaskets as standard, to protect inquisitive little fingers.

Choose from a range of standard handles or revel in the high quality durable stainless steel option. Our multipoint locking system, internally beaded frame, high security hinges and anti-drill key cylinders all come as standard for your peace of mind.

Take it easy with our maintenance-free aluminium frame that will not warp, rot or need varnishing. And relax knowing you are fully covered by a 10-Year manufacturer’s guarantee and our insurance backed 10 year guarantee on workmanship.

The unique free-glide running system uses near frictionless, maintenance-free needle roller bearings encased in tough nylon making all our doors a breeze to open or close. An equal sightline provides a regimented look.

Concealed Track (Standard Threshold) on our Aluminium Bi-folding Doors

Our Aluminium Bi-folds have a concealed track. This has many advantages including:

• Track cannot be removed - highly secure.
• The doors have a clean, smooth appearance as there are no extra "bolt-ons".
• Standard threshold provides optimal weather performance.
• Standard threshold with open-out doors gives it further security as doors rest against up stand when pushed from the outside.

We can also fit our folding doors with a low or even Flush Threshold.
