Aluminium Bi-Fold Door Features

Aluminium of old became known for offering a poor degree of thermal efficiency, making it an inferior choice in the face of the uPVC alternative. Our aluminium bi-fold doors, however, are designed to bypass this problem. They feature a thermally broken frame and polyamide bridge to offer a contemporary standard of heat retention to keep the outside, outside.

Installing our aluminium bi-fold doors into your home will do more than just increase your comfort during the colder winter months, you could also find yourself saving money on your heating bills too. This is made possible by allowing the warmth from your central heating to stay in your home for a longer period of time, reducing your reliance on it to potentially lower your heating costs.

All of our aluminium bi-fold doors are manufactured using premium grade aluminium, which means that they are able to offer you a degree of structural integrity that will last the test of time. Even after constant use and exposure to the elements, these doors will continue to uphold a beautiful ‘as new’ look.

Further to this, our aluminium bi-fold doors effectively bypass any of the problems that would usually accompany a traditional timber door design. With this in place, you won’t have to worry about any warping, discolouring, twisting, cracking, or bowing out of shape: meaning you won’t have to cut, sand, or repaint your new door.

Although inherently slim and sleek in their design, our aluminium bi-fold doors are still able to achieve an impressive degree of security. You’ll be able to enjoy the peace of mind that comes with an aluminium bi-fold door that combines a highly-secure profile with intelligently designed locking systems to offer an exceptional degree of security from the ground up.

All of the aluminium bi-fold doors that we offer feature multi-point locking systems that are professionally integrated into the frame to ensure they can’t be used as a potential leverage point. In turn, these locks engage at multiple points of the frame to keep security consistent, combatting modern burglary trends to keep you safe.

Thank you to you and all your colleagues involved in the project.  Without exception, everyone we have had on site has been a delight.  Everyone, from the word go has worked exceedingly hard to get the job done and, considering the weather, in exceptionally hard, cold and wet circumstances.  The guys have all been so helpful, polite, professional, courteous and friendly and nothing was too much trouble.

Customer in
Winchester - August 2017

Before retiring my husband worked for over 30 years in the industry so knew what standard of work he wanted from the various tradesmen. He could not fault any of them and we got the finished job we had hoped for. We are very happy and can highly recommend County Windows to anyone else considering them for similar projects.

Mrs Tomkin
Ferndown - March, 2019

County Windows replaced our conservatory roof, the installation team put our minds at rest from the very start. They did a fantastic job, and after the three days it took to do the job you would not have known they had been there. Our conservatory now looks great, thanks to all at County Windows, especially the installation team.

Conservatory Roof
Southampton - April 2019

I’m writing to say how pleased we are with our new conservatory roof. I have not contacted you before as we have been waiting for it to rain and it passed with flying colours. Also, my wife and I must mention the fitters, Jamie and Danny. We cannot praise them enough, they were always on time, kept us in the loop as regards to finishing off, the attention to detail was first class and they were pleasant to deal with. All in all, a very nice pair of lads. Thank you.
