Smarts Visofold 1000 Bifold Doors
UK’s most popular aluminium bi-folding door systems

The Smart Visofold 1000 is one of the UK’s most popular aluminium bi-folding door systems, trusted by homeowners and installers alike. This versatile folding door connects indoor and outdoor spaces seamlessly, offering wide, unobstructed openings. With its slim sightlines and modern design, the Visofold 1000 suits both contemporary new builds and traditional homes. Every Visofold 1000 door is manufactured in-house by BM Bifolding Doors, ensuring precision quality and reliable performance tailored to your project.

  • Slim Profiles & Wide Views: Slim meeting stiles (around 122 mm) maximize glass area for panoramic views and daylight. The sleek frame design creates a modern, minimalist aesthetic.

  • Thermally Efficient: Enhanced 30 mm polyamide thermal breaks and insulated profiles achieve U-values as low as ~1.4 W/m²K (with double glazing and thermal foam), meeting strict UK Building Regulations (Document L) for energy efficiency. This keeps interiors warm in winter and reduces energy costs.

  • Robust & Secure: Features multi-point locking systems and high-strength hardware. The latest Visofold 1000 upgrade includes PAS 24:2012 certified rollers and improved shoot-bolt locks for enhanced security. You get peace of mind knowing the doors exceed standard security requirements.

  • Smooth Operation: Precision-engineered running gear and magnetic catches ensure the folding panels slide and fold smoothly without judder. Even large 100 kg panes open with ease, held firmly in place when opened (no sudden slamming in wind).

  • Low Threshold Options: Choice of an integrated cill or low threshold for flush floor levels. This provides easy, wheelchair-friendly access between inside and outside without compromising on weather performance.

For Homeowners &
Business Owners

Upgrade your living space with a Visofold 1000 bi-folding door and enjoy transformative indoor-outdoor living. Homeowners love how these doors flood rooms with natural light thanks to their slim frames and expansive glass panels. When closed, the thermally broken aluminium keeps your home comfortable year-round, and when open, the entire aperture is clear – perfect for summer gatherings and entertaining. Visofold 1000 doors glide effortlessly and stack neatly to the side, creating a seamless transition to your garden or patio. High-quality seals and precision engineering also mean excellent weatherproofing, so you won’t feel drafts or leaks even during British winters. Business owners (like cafés or event venues) can use these robust folding doors to open up facades and attract customers, knowing they meet all required safety standards. Every Visofold 1000 is made by BM Bifolding Doors in the UK, so you get bespoke sizing, hundreds of finish options, and expert installation from a local specialist. It’s a stylish investment that adds real value, security, and wow-factor to your property.

  • Panel Configurations: Available from 2 up to 7 panels, with various opening schemes (all sliding one way or split). Includes an optional traffic door for convenient everyday use.

  • Materials: High-grade aluminium with polyamide thermal breaks (fully thermally broken profiles). Dual colour option allows different finishes inside and out.

  • Hardware & Security: Multi-point locking with shoot-bolts, internally beaded glazing, and secure hinges. Standard hardware is PAS 24 rated for enhanced security. Doors are internally glazed for security and have built-in anti-lift features.

  • Sightlines: Slim 94 mm sash profiles and ~122 mm interlock junction for a modern look. A new heritage-style sash option is available for traditional or steel-look aesthetics.

  • Thresholds: Choice of rebated threshold with integrated sill (best weather rating) or low-profile threshold for flush floors. Low thresholds meet Part M accessibility needs for wheelchair access.

Supplied in an endless array of finishes. Choose from Smart’s standard RAL colours or bespoke shades to match your decor – popular options include Anthracite Grey, Jet Black, and Chalk White.

Dual-colour profiles are available (e.g. grey outside, white inside) at no extra cost. We also offer textured metallic finishes from the Smart Sensations range for a unique look.

All coatings are high-quality polyester powder coat for longevity in the UK climate (minimum 25-year finish life).

Visofold 1000 doors accommodate 24–40 mm double or triple glazing for excellent insulation. We typically fit Low-E double-glazed units with argon gas and warm-edge spacers for an A-rated energy performance, helping your bifold achieve around 1.4 W/m²K U-values. Glass is always toughened safety glass (to BS 6206/EN12150) for safety. Options include neutral solar control glass to reduce overheating on south-facing elevations, acoustic laminated glass for noise reduction, or integrated blinds within the glass (see our specific product for integral blinds). Decorative glazing like frosted or patterned glass is also available for privacy where needed.
