• Authentic Steel-Look Design: Ultra-slim sightlines (as narrow as ~59 mm at the door meeting stile) replicate classic steel French doors and screens. Slim horizontal glazing bars and optional grid layouts give a vintage industrial aesthetic that’s virtually indistinguishable from original steel windows.
• Modern Thermal Performance: Though they look vintage, these bifolds are fully modern inside. A thermally broken aluminium frame and 28–36 mm glazed units achieve U-values around 1.5 W/m²K – far warmer than old steel doors. You get period style with energy-efficient, draft-free comfort.

• Secure & Robust: Built with internal reinforcing and multi-point locks, our heritage bifolds meet PAS 24 security standards. You can enjoy expansive glass and classic looks without worrying about safety. Laminated security glass upgrades are available for added peace of mind (meeting Document Q requirements for security).

• Tailored for Character Properties: The heritage system was designed as a direct replacement for traditional steel doors. It’s ideal for conservation areas or Victorian/Georgian homes, maintaining the sightlines and elegance of original designs while adding modern convenience. Even narrow mullions and transoms are possible to match original patterns.

• Premium Finish & Details: Every detail complements the vintage look – from black or graphite powder-coat finishes to classic handle designs and slim backplates. We align mullions and glazing bars seamlessly across door sets, achieving an “industrial” grid appearance that design-savvy homeowners and architects adore.

Our Heritage Style bifolds allow you to tap into the booming demand for steel-look glazing in both residential and commercial projects. As a fabricator/installer, you’ll appreciate that BM Bifolding Doors uses the Smart Heritage system, which integrates with the popular Smart Visofold series. This means familiar fabrication techniques and easy sourcing of sections and hardware. We supply heritage bifolds with pre-fitted glazing bars and all needed hardware, simplifying on-site assembly. Trade clients benefit from competitive lead times (usually 5–6 weeks) and bespoke designs – odd sizes or shapes (like arched head bifolds) can be accommodated to match architectural features. We also offer training and support on installing these doors, as they have specific sightline alignment considerations. By offering Heritage Style bifolds, you can provide your customers with a high-end, design-focused product that’s backed by our technical expertise. It’s a great upsell for period refurbishments, trendy bars/restaurants, or loft-style interiors, giving the classic steel look with the practicality of aluminium.

Heritage Style Bifold Doors are perfect for homeowners aiming for that charming industrial or Art Deco vibe. When closed, the multiple small panes divided by slim grids create a classic atelier window feel – a gorgeous design feature in itself. When open, they fold away to transform your space with fresh air and open-plan flexibility. These doors complement converted barns, warehouse lofts, or extensions on older homes, preserving character while introducing 21st-century comfort. Businesses like cafés, galleries, or boutique shops also love the style – it offers a distinctive frontage that echoes historic storefronts and draws the eye of customers. Despite the traditional look, you won’t be dealing with rust, repainting, or rattling panes: our aluminium heritage doors are low-maintenance and built to last, with durable powder-coated finishes that won’t chip or peel. Double weather seals keep out drafts, and modern gearing ensures even large multi-panel sets slide open smoothly. You get the best of both worlds – heritage aesthetics and contemporary reliability – enhancing your property’s curb appeal and value.
