Heritage bifold doors

Our aluminium heritage bifold doors are designed with horizontal bars across the glass to match the look of Art Deco style steel doors

Build It Awards 2021 shortlisted badge for best glazed doors, recognising IDSystems' award-winning bifold and sliding door expertise.

Build It Award | Shortlisted for prestigious 'Best Glazed Doors' category

The stylish design and unrivalled performance of our heritage bifold doors have been recognised by the expert judges at the annual Build It awards, where the system has been shortlisted for the 'Best Glazed Door' category at the 2021 awards.

Slender frames and square edged profile

At the heart of the appeal of Art Deco style doors is the slender frames and traditional appearance. The SUNFLEX SF55s doors feature the narrowest frame depth (55mm) of any bifold door on the market, which combined with their stylish square edged profile, makes them the perfect base for our heritage range.

Traditional style, modern design

Our SUNFLEX aluminium heritage bifold doors provide the stunning appeal of traditional steel doors with slim frames and horizontal bars when closed, yet when completely opened up they create an ultra-modern and seamless connection between home and garden.

Tried and tested technology

Our heritage bifold doors are designed utilising our award-winning SUNFLEX aluminium systems and backed by more than 30 years of folding door experience. Designed in Germany and installed across the globe, SUNFLEX's premium quality products are renowned for their innovative design and stunning appearance.

Heritage bifold doors with eight glass panes arranged in two columns, featuring slim white frames and maximum glazing for light and views.

Utilise the bifold door frame to create French doors

The versatility of the SUNFLEX SF55s bifold doors mean they can be even designed as French door systems - with double doors opening inwards or outwards. Perfect for larger doors (with panels up to 3m tall and 1.1m wide) and all with the same contemporary square-edged profile and Art Deco style design.

White aluminium-framed windows with multiple panes open outward against a bright blue background, showcasing slim-profile glazing design.

A choice of complementary products

To match our heritage bifold doors we can also design, manufacture and install a range of Art Deco inspired glazing systems to complement the bifold doors, including French doors. (with or without sidelights), aluminium windows with matching horizontal bars and even our SF22 internal glass partitions.
