​​Panoramic doors create the perfect summer ambience, and with stunning openings of up to 6m wide, you really can bring the outside in. Depending on the door configuration you choose you can utilise various opening positions to allow refreshing ventilation into your home on those hot summers days.
Imagine hosting a summer garden party or barbeque – your panoramic door will offer seamless access between your home and garden, allowing you to impress guests with your fantastic opening. Plus, it will make it easier when you want to take your furniture outdoors for alfresco dining!

Stunning designs and the feeling of more space will enhance your lifestyle and improve the value of your home.

Easier, smoother operation
Each panoramic door has a built-in four-rail aluminium roller track so that it glides open or closed smoothly and effortlessly. The unique D-shaped interior handle allows the doors to fold back flatter. So when they’re open they look much neater and won’t distract from the beautiful view of your patio or garden. Plus, the D-handle has an intelligent antimishandling feature which stops your floor from being scraped by the shoot bolts, plus it protects the bolts from being damaged and needing replacement – the main cause of repairs on folding sliding doors.
Extra security – PAS 23 /24
We know that the security of your home is vitally important, that’s why we have built our doors with enhanced security features, which has earned us the comprehensive PAS 23/24 security certification. We’ve also included stainless steel anti-jemmy pins in our door design. This means that the door can’t be removed from the outside by intruders trying to get into your home. These pins are enclosed in the roller track for maximum security.

Warm in winter...

​When the harsh British winter is in full swing, it’s vital that you choose doors which can withstand what it throws at us. That’s why our PVC-U doors are manufactured with a square-edge profile which gives a superior seal along door edges, making them draught and weatherproof.
​Tested to BS6375-1:2009 (Performance of Windows and Doors), our doors far exceed the minimum requirements set out for the most extreme weather test. They also meet the British Standard minimum requirements for construction, security, safety, weather-tightness and strength of performance. This means behind their striking looks, your folding sliding door is robust and built to last – giving many years of pleasure.

Bi-fold Doors have become the standard in modern day homes. The versatility and function of the doors coupled with high security and pleasing aesthetics put them  high on any wish list. Bowker Glass offer the doors in either low maintenance Upcv or Aluminium profiles. Standard colours are either White, Anthracite Grey or Black and can been dual coloured in any combination. Your colour choice does not end there, any RAL colour can be specified to create a look that is personal to you.

Access for all
In addition to our standard threshold, we offer various options for those requiring a flusher-fitting low-threshold, to best suit your needs.
For external doors, we offer three low-threshold options, including a Part M compliant double ramp threshold that allows easy pushchair and disabled access, as set out by the Building Regulations. 
If you want a low-threshold for an internal bi-fold door, then we have a flush-fitting threshold that allows seamless integration of two rooms.

Versatile space at its best

Panoramic doors create a wider opened space than French or inline patio doors, enabling you to make the most of your living area. When fully retracted, they create up to a 90% open space, turning your outside area or patio into another useable room. Doors can be manufactured up to an impressive six metres wide, offering a simple yet stunning way to enhance your environment.
Because every home is unique, we offer a choice of folding options, allowing you to choose how your door works. This maximum versatility helps you to enjoy and expand your home in the way that works best for you.

Our superb collection of panoramic doors offers market-leading aesthetics, engineering and value. With a choice of designs and guaranteed high-quality performance, they bring you the space, comfort and low-maintenance luxury of modern living. 
Imagine wide open spaces allowing air and light to flood into your home, instantly creating a contemporary look and feel. Our new panoramic doors will add the ‘wow’ factor to your home and can be fitted wherever you need easy access to your patio or garden. No wonder more and more people are choosing our PVC-U panoramic doors to add that extra dimension to their homes. The collection offers ultra slim frames for eye-catching looks, clever new design features and a wide range of colours to suit every home perfectly. In short, our new folding sliding doors are superior to any other similar PVC-U products you’ll find on the market today

Even more streamlined
Our panoramic doors have been designed with slimmer, uncluttered sightlines to make them less obtrusive. This means that you see less of the doors and more of your patio, garden or the interior of your home. We’ve also incorporated a new trim to hide the seals between the door leaves. This adds to the whole aesthetic look and feel of your new doors, as you won’t see a line of black seal between the doors when they’re closed. To complete the clean, simple lines of your new doors, we also give you the option of a flush-fitting low threshold below the doors.
