Bifold PVC-u

Contemporary, architecturally designed Bi-Folding Doors, which create a stunning feature for your home. Bi-Folding Doors can complement any home and will give you a whole new feel as you will open up panoramic views and bring the warmth and light of the outside, indoors. Increasingly popular, Bi-Folding Doors can be chosen to match the style of your home and provide a smooth transition between your rooms or between indoor and outdoor spaces.

You can choose from PVC-u or aluminium and they make an attractive alternative to French Doors or Patio Doors. They are available in a wide range of colours and finishes. The doors remain slim in profile and relatively unobtrusive owing to the strength of the modern materials used. Our Bi-Folding Doors boast highly sophisticated folding and sliding technology to give many years of trouble free use. These elegant concertina doors add a real WOW factor to your home and seamlessly connect your outdoor and indoor spaces.

Add the wow factor to your home

Imagine being able to open up an entire wall of your room, creating space and letting fresh air and natural daylight flood into your home.

Whether you have a bedroom with Juliette balcony, a dining kitchen, a conservatory or an orangery, bi-folding doors can provide a stunning alternative to patio or French doors.

Stafford uPVC Windows’s bi-folding doors were the first fully bespoke PVCu bi-folds to be designed, engineered and made in the UK – and we believe they are still the best.

Available in a wide choice of opening configurations and colours, your Stafford uPVC Windows bi-fold has ultra-slim sightlines, providing your room with a clean, modern appearance.

Safety features include the innovative low threshold option for family friendly and wheelchair use. What’s more, the Stafford uPVC Windows bi-fold offers high energy efficiency, combined with the best security features on the market – bringing you a modern space saving solution for your home that will definitely give it the ‘wow’ factor.

A grand design

Bi-folding doors are becoming more popular than ever before, thanks in part to their regular appearance in television home make-over and lifestyle programmes.

Timber or aluminium are often perceived as the only materials that can be used for bi-folding doors, but doors made from lead-free PVCu can actually offer many more benefits:

  • Smoother operation
  • Higher thermal efficiency
  • Lower maintenance
  • Can perfectly match your other doors and windows

With Stafford uPVC Windows’s foiled woodgrain-effect options, your bi-folding doors can have the appearance of timber, without the need to repaint them each year.

If you choose our flat grey frames, your bi-folding doors will rival the most contemporary aluminium range on the market, keeping your home much warmer at a more cost effective price.

And Stafford uPVC Windows’s ‘top of the range’ ModLok™ bi-folding door offers even greater strength and rigidity, combining all of the structural benefits of an aluminium door set with the energy efficiency of PVCu.

Discover why more and more people are choosing Stafford uPVC Windows’s bi-folding doors to add an extra dimension to their homes.

Your home, your choice

The Stafford uPVC Windows range offers complete flexibility, whatever the room or the size of opening you need.

Manufactured in our decorative sculptured profile, Stafford uPVC Windows bi-folding doors are available in a wide variety of colours.

With options from two to seven panes, all with our beautiful, super-slim sightlines, you can also choose how many doors fold back to each side of the frame.

The Stafford uPVC Windows standard bi-fold door range is available in a wide range of configurations whilst the Stafford uPVC Windows ModLok™ bi-folding door range offers an even greater number, due to its additional strength and rigidity.

Combining aluminium reinforcing within the bi-fold doors and frame with a high security locking mechanism, the Stafford uPVC Windows ModLok™ bi-fold offers all the structural benefits of an aluminium door set combined with the thermal benefits of PVCu – bringing you the best of both worlds.

Our door pane numbering works like this:

  • The first number shows the number of doors in total within the frame.
  • The second number shows the majority of doors folding back to either left or right.
  • The third number shows the balance of doors opening in the opposite direction.

So, a 4-3-1 bi-folding door would be four panes wide, with three doors folding back to one side of the frame, and a single opening door on the other.

A brand new concept in locking technology, ModLok™ has been developed by Stafford uPVC Windows to enable even wider door configurations.

Designed for living

Stafford uPVC Windows’s bi-folding doors are crammed full of innovative design features.

Low maintenance

With a set of Stafford uPVC Windows bi-folding doors you can rest assured that you won’t need to spend hours looking after them to maintain their beauty.

Our 10 year frame guarantee gives you the peace of mind that the colours won’t fade – and not only that, you won’t need to treat or paint them each year to keep them in tip top condition.

Just an occasional wipe down with soapy water is all they need to keep them looking their best.

Family friendly

The Registered Design protected Stafford uPVC Windows low-threshold option creates a seamless entrance and exit, making it ideal for family homes. An optional tray to seat the low threshold creates an easy-access ramp for wheelchairs and prams.

Ultra-low, the Stafford uPVC Windows threshold measures just 24mm at its highest point, with silver or gold finish available to perfectly complement the door hardware.

Strong and secure

The shootbolt locking mechanism designed into each Stafford uPVC Windows bi-folding door ensures the door is bolted firmly into the stainless steel track, maximising your security. Built in anti-lift features, anti-bump cylinders and optional anti-snap cylinders combine to bring you peace of mind.

Stafford uPVC Windows’s bi-folding door range is also available with ModLok™, a new concept in locking technology.

ModLok™ is a highly innovative combined reinforcing and locking mechanism, bringing additional strength and rigidity to the doors and enabling you to have even wider configurations of bi-folding doors.

ModLok™ also offers enhanced security features including 3 opposing hooks and 2 shootbolts built in to every master door, plus 2 anti-lift shootbolts on every slave door.

The Stafford uPVC Windows ModLok™ bi-fold offers all the structural benefits of an aluminium door set combined with the thermal benefits of PVCu.


We’ve added slim hinges with the fixings hidden inside, not only maintaining the sleek lines but enhancing security as they can’t be unscrewed from outside.

We wanted to offer a low threshold, without the need for expensive and messy excavation, so we designed our own clever solution. We’ve even designed folding keys, to avoid any problems with keys being left in the locks during operation – it’s often the small things that make a huge difference.

Super smooth action

Your bi-folding doors are engineered to give you the reassurance that they won’t bend or warp – whilst the super smooth rolling action makes them feel incredibly light.

Ergonomic handles are built in to each hinged section, making the doors easy and safe to operate for all age groups.

Stafford uPVC Windows’s patented roller mechanism is hidden inside each door, maintaining its sleek lines and giving all Stafford uPVC Windows doors the most effortless glide action on the market.

Discreet magnets ensure that when the doors are folded back, they will remain securely in place.

And with our ModLok™ range, only the “master” door will open first, so no chance of spraining locks by trying to open the wrong door.

Open up your business

Not just for the family home, Stafford uPVC Windows bi-folding doors can bring a whole new

dimension to your commercial or business property.

Maximise floor space at your pavement café by opening up an entire wall in the summer months, whilst knowing your energy efficient Stafford uPVC Windows bi-folding doors will also keep in the heat during the winter.

Or give your showroom a new lease of life by installing Stafford uPVC Windows bi-folding doors for ease of access together with the highest possible security.
