Spotlight on: Aluminium Bifold Doors

Aluminium bifold doors have quickly become one of the most popular double glazing additions to any new build project. These innovative, concertina style doors have taken the market by storm.  With their sleek sight lines, advanced mechanism for super smooth operation and exceptional U values capability, bifold doors can transform any property, flood living spaces with natural light yet keep the weather out and the heat in during colder months.

At Tradeglaze we make our aluminium bifold doors using the Optio BSF70 system by the industry’s leading UK manufacturer AluK. Our doors are secure, durable and weatherproof, allowing to provide homeowners with complete peace of mind. Our aluminium bifold door prices are competitive and all our products are manufactured here in the heart of Lincoln in our modern aluminium factory, bespoke to your exact requirements.

With our bifold doors you have an extensive choice of configurations to choose from. We can make bifolds from 2 panes up to 7 panes, to suit your project requirements. Your door can slide to the left or right, include fixed panes, and we can add a traffic door for an easy access (odd number pane configuration only), which can open in or out to help you maximize available space. With 17 configuration options, you are sure to find the perfect solution for your project. The system also boasts a unique flush line Optio bifold pop-out handle that allows for square flush stacking panels when doors are fully open.

With colour options, the possibilities are limitless. All our aluminium products are available in any RAL colour, as single or dual colour and anodised finishes. Opt for the popular ‘Anthracite Grey’ shade for a sleek, modern aluminium style or choose from traditional tones such as ‘Agate Grey’ to add a period flair to your project!

How thermally efficient are your bifold doors?

Energy efficiency and aluminium haven’t always gone hand-in-hand. However, technology has advanced rapidly in the recent decades. Nowadays, the Optio BSF70 aluminium bi-fold doors are some of the most energy efficient double glazing products on the market, with glass U-values as low as 1.7 W/m2K.

Do you offer Supply Only bifold doors?

Absolutely. Choose Supply Only or opt for Supply & Fit and we will take care of the installation for you. For any folding sliding door to work properly it is vital that it is installed correctly to ensure the door panels fold and slide effortlessly as they are designed to do.

Installing bifold doors not appeal to every customer as it can be a time consuming job for them especially if they have to re-visit to correct a traffic door that has dropped or a door that won’t close correctly. We have specialist aluminium installation teams with many years of experience of installing aluminium products on new build sites. In addition, all our bifolding door installations are protected by an insurance backed guarantee, for your complete peace of mind.

Whatever your choice, we will work with you to provide the product and service that is right for your project.

We manufacture all our bifolding doors in our Lincoln based factory, bespoke to your project specification.
