Blending timeless character with modern performance, our steel-look heritage bi-folds are a striking addition to any home. Designed with a specially developed sash that mirrors the appearance of classic steel doors, they open up living spaces while echoing the charm of a bygone era.
Whether you're renovating a period property, working within a conservation area, or adding a touch of heritage to a new extension, these aluminium bi-folds pair beautifully with our matching external windows and heritage doors — creating a cohesive, characterful look across your home.
Smooth to operate, low-maintenance, and thermally broken for year-round efficiency, they meet today’s requirements for safety, security, and accessibility, while staying true to traditional aesthetics.
Decorio heritage bi-folding doors offer a seamless replacement for old steel doors, maintaining the classic look essential for historic and period properties.
Their versatility, however, extends far beyond traditional settings—these doors are equally at home in modern residential and commercial projects, adding character and style with a steel-look finish and contemporary performance.
Our heritage bi-folding doors begin with a two-panel setup and expand right up to nine-panel configurations — perfect for wide openings, garden rooms, or bold architectural statements.
But they’re not just for big spaces. The same system can be styled as a single or French door, allowing you to carry the same elegant steel-look aesthetic throughout your home. Whether it’s for a compact rear entrance or a grand patio reveal, Decorio bi-folds offer flexibility without compromising on heritage charm.
Ideal for smaller openings or rear access, the single door option retains the classic heritage look without requiring a handle block.
Offering a wider opening without the need for handle blocks, the French door spans up to 2450mm wide—ideal for creating balanced, elegant transitions between home and garden.
With options for up to 9 sashes, this design maximises natural light and opens up entire walls for stunning, unobstructed views.
For added accessibility, a 15mm low threshold is available. Fully compliant with Part M building regulations, this option provides easier access for those who need it.
Ramps can also be fitted inside and out to create a smooth, step-free entry.
Our advanced thermal break technology delivers excellent insulation, helping keep your home energy-efficient all year round.
Paired with high-performance glazing, our doors meet the latest Document L building regulations for thermal performance.
Every master door is fitted with a robust, security-tested multi-point locking system as standard.
An additional sash includes a reinforced shootbolt with key locking for added
peace of mind.
