Bi Fold Doors

Discover our exciting range of aluminium bi fold doors

We make and install our own brand of bi fold doors in Kent & Surrey.  Unlike most other brands of bi fold doors, ours were designed specifically for the British market and climate in mind from the very beginning. We use heavy duty, precision engineered thermal aluminium profiles to give the strength and support that wide-opening doors require.  Our doors have been designed to shrug off the extremes of temperature the UK weather throws at us, and will never warp, twist or bow out of shape like so many lesser bi fold doors. 

Ideal for patios and conservatories

The bi fold door is available in 2 - 7 pane configurations.  They are the ideal doors for use in open plan kitchens and conservatories, where the ability to open your home completely to the garden or patio will make barbecues, parties and family days at home far more enjoyable.  They are quick and easy to open and close, and all feature a 'passenger door' for everyday access when the wide opening is not required.


Micron offer a huge range of stock colours and finishes on our bi folds.  Choose from many different RAL colours to match your property perfectly.  We can offer bespoke colours to match the most unusual property styles and designs.  Our aluminium bi folding door systems can be ordered in dual colours, allowing a different finish on both the inside and outside frames.  As well as our standard painted finishes, we have three stunning sublimated woodgrain effects, replicating the luxurious finish of Walnut, Rosewood and Oak.


All Micron bi-folding doors come with a choice of opening in or opening out, with either left hand or right hand sliding with easy-glide stainless steel wheels and rollers ensuring continuous smooth operation.  

Our sliding operation on the bi-folding door relies on a high quality stainless steel track, on which quad rollers are fitted to the door leafs and glide along in elegant fashion. The same quad rollers are fitted with a small brush on one end to keep the tracks free of dust and dirt.

Homeowners have the option of 2, 3, 4, 5, 6 or 7 section folding doors.

Our doors are manufactured to your exact specifications and sizes.  We do not sell off-the-shelf products.  

We can combine our bi folding doors to create large opening areas, allowing you to open up your home to the garden or patio.


As with all of our products, our bi fold doors are available in an array of colours and finishes.

The colour options for bi-folding doors are as varied as the configuration options.  We offer sublimated woodgrain finishes of Walnut, Rosewood or Oak, or a powder coated colour finish which gives you a wider array of possibilities.

Dual-colour finishes are, as the name suggests, are one colour on the inside and another on the outside so that you can complement both your internal décor and outdoor space with the most appropriate shade.

Micron folding sliding aluminium doors employ a graceful, effortless concertina of the door leaf.  The smooth action says volumes about the integrity of the installation and the property which houses them.

Unlike traditional sliding patio doors, in seconds you can open up a full wall and not just blur, but almost eliminate, the boundaries between the indoors and outdoors.

When installed internally, you don’t have to commit to either one fully open-plan room or two permanently divided; bi-fold doors allow you to pick and choose depending on the occasion.

Bi-folding doors are hugely practical.

Our doors are available in numerous configurations, consisting of anything from two panes to seven.

Each style of bi-folding door incorporates a ‘passenger door’ which functions like a standard hinged door for everyday comings and goings.

Micron doors are designed to be inherently easy to operate.  All members of the family will find operation of the doors a doddle. 

Our Bi-folding doors are simply a pleasure to use thanks to the ease of their concertina operation on gliding rollers.

If you’re preparing to entertain it will take a matter of seconds to merge your indoor space with your garden. And if the weather takes a turn for the worse it is just as easy to reinstate the boundary.

The design of the bi fold doors is second to none.  The fashion for wide open spaces in our homes has directly driven the way we design our products.

Whether open or closed bi-folding doors enable excellent panoramic views and are certainly the latest concept in luxury living. Homes of all shapes and sizes are now adorned with this impressive style of door which changes the way that people view and use their home.

Barbecues, parties, late night drinks around the firepit - the bi fold doors complement the way we live our lives today.


Bi folding doors can be used virtually anywhere.  There is no set rules as to when you can install them.

The can be used on the front of conservatories and orangeries to allow the whole room to open into the garden.  They are ideal for replacing old french doors and sliding patio doors in kitchens and living rooms.

They can also be used internally as a barrier between the conservatory and your main house.
