Premium, sophisticated French doors created using our incredible Ultra-slim bifold door profile

Why Start With the JA48 French Door Profile?

What Are The Benefits Of French Doors?

A French door makes for a pleasing and practical entry point to a home. Our Aluminium french doors are available in a contemporary slimline aesthetic with our JA48 profile or a more traditional crittel style with our Smart Heritage profile – all allow for plenty of natural light and are a perfect choice if an opening is not wide enough for a bifolding door or sliding patio door, or just as a tasteful and traditional alternative. Our French doors are incredibly energy efficient and share all the attributes of our other aluminium door products.

Glazing – JUST the right choice

JUST aluminium installs Low E glass in our French doors as standard. LowE glass is one of the most energy efficient glazing products in the UK, specifically designed to help homes reduce their energy consumption and save money on energy bills. Energy efficient glass also performs exceptionally well using the JA48 or Smart Heritage door profile and our choice of hardware, making it the perfect choice of glass for any home or commercial property.

Handles – JUST choose the perfect finishing touch

 Whatever colour door frame you choose, we have the perfect handle to match. We would recommend a matching handle to frame so the hardware is less noticeable and uniform, however chrome and satin options can add an element of sophistication.
