Bi-folding Doors

There’s no doubt that bi-folding doors look amazing. And they’re fantastic for opening up your living space to the great outdoors. But if you’re considering installing a large, floor-to-ceiling glass feature, you’ll want to make sure it’s one of the best. Carlos Windows & Doors are trusted because they develop and thoroughly test products that work, withstand the weather and which are safe and secure.

Bi-folding doors can have between three and seven panes. Depending on the size of your home they can be combined with fixed panes to create an even larger feature. They can open either external to your living space, or internally, and there are low-threshold options to make access easy. The position of the access door is variable to suit your needs and bi-folding doors can be made in any of our colours and woodgrain finishes. If you want, you can choose different colours for the inside and the outside.

Carlos Windows & Doors bi-folding doors are secure, with hook latches and multipoint locking, and made using profiles with Secured by Design status. With toughened, energy-efficient glass throughout, and your choice of double or triple glazing, these doors ensure your living space is comfortable all year round.


With our huge range of exclusive doors we also offer you a complete range of accessories from handles, to threshold options, to opening configurations. 

Our bifolding door handles are luxury products, made exclusively to a design and crafted from Stainless Steel. They can only be purchased through a Design Partner and we know that only stainless steel handles can be guaranteed for 10 years.

Please consider your choice of ancillary hardware carefully because that is what you will eventually notice most when your products are installed. Check out the finishes on our handles because it is attention to detail that helps make this unique product range so exciting.

Safety & Security

Our bifolding doors are designed to discourage intruders, thanks to the master door security locking system and intermediate handles with shootbolts which can also be supplied with key locking. All these elements prevent our bifolds being lifted off their base channel or being jemmied when closed.

Colour Options

A little time and care with your choice of colour is advised and your selection should be influenced by your style of property, surrounding architecture or your other windows and doors. Just choose from our range of popular colours, let us know your sizes and how you would like the doors to open and we can make your Bifold door in a minimum of 4 weeks from the date of order.

You should also carefully consider the colour of handles inside and out.

Material Information

Aluminium is the optimum material for manufacturing windows and doors and that is why it is widely specified by Architects for most serious new build and refurbishment projects. 

Aluminium doors require very little maintenance, just a wipe with a damp cloth when needed and a regular check to ensure the track is kept free from grit and small stones to ensure the doors continue to run smoothly. Aluminium is more resistant to the elements than PVCu and is not likely to warp or rot. We offer a 10 year warranty on standard paint in a choice of 7 colours or 25 years warranty on Marine Grade paint.
