  • Panoramic Views: Designed with slim interlocks (as narrow as ~35 mm with the slim interlock option) to create an almost uninterrupted glass wall. Even the standard interlock (~83 mm) is sleek. This means more glass, more natural light, and breathtaking views of your garden or landscape.

  • Smooth & Effortless Operation: High-quality rollers and track system ensure even large panels (up to 250 kg) slide with minimal effort. The inline sliding design means panels glide within their frame tracks, and an optional lift-and-slide gear upgrade is available for feather-light motion and secure locking in any position.

  • Thermal Excellence: Visoglide+ features extended polyamide thermal breaks in all main sections, achieving U-values as low as ~1.4 W/m²K with double glazing. In fact, with the Visoglide Plus “upgrade” profiles and a 1.0 W/m²K center-pane unit, it meets new-build energy targets easily. This keeps indoor spaces warm and efficient – exceeding building regs for both new builds and replacements.

  • Flexible Configurations: Available in 2, 3, 4, or 6 panel configurations with double or triple tracks. You can design openings up to 6 meters or more – for example, a 3-panel slider with 2 panels stacking behind one fixed pane, or a 6-panel meet-in-the-middle design. The system supports multiple opening combinations and even a pocket sliding variant (into wall) if specified.

  • Certified Security & Quality: These doors are PAS24:2022 tested and BS Kitemarked for security. They come with secure multi-point locking and anti-lift devices. Additionally, they are weather tested to BS 6375, ensuring resistance to heavy rain and wind. You get peace of mind that security and durability are built-in, despite the large expanses of glass.

For Trade Professionals

Visoglide+ is a reliable sliding door system that fabricators and installers trust. BM Bifolding Doors provides trade customers with made-to-measure Visoglide+ units, precision-fabricated for straightforward installation on site. We can supply huge sizes (individual sashes up to 2.5 m tall and ~1.7 m wide) thanks to the system’s robust design, allowing you to meet client demands for big glass. Trade installers will appreciate the Quick-Glaze bead feature and co-extruded gaskets which speed up glazing and improve finish quality. The frames feature a 100 mm depth that matches well with standard cavity wall constructions, and trickle vent options can be integrated neatly for compliance with ventilation requirements. If your project calls for it, Visoglide+ also adapts to automated opening – the system can accept sliding door motor kits for luxury applications.

BM Bifolding Doors offers short lead times and consistent quality control (every door is test-assembled before delivery). With full technical support, including CAD details and installation guidance, we make it easy for our trade partners to deliver a flawless result. Offering Visoglide+ allows you to cater to the segment of clients who prefer a sliding solution over bifolds – whether for aesthetic reasons or to accommodate very wide openings with fewer vertical lines.

For Homeowners & Business Owners

Visoglide+ sliding doors are a superb choice for those wanting maximum light and views. Homeowners will love how these doors transform a room – large glass panels invite the outside in, creating a bright, airy atmosphere. Because the panels slide rather than fold, you always have one fixed pane, giving an almost picture-window effect even when closed. This is great for framing a garden view or scenic landscape. The operation is user-friendly: a gentle push and the door glides open, thanks to quality bearings (and with a lift-and-slide handle, it’s even easier). The low threshold option provides a near-flush transition to outdoors, ideal for wheelchairs, prams, or simply avoiding trip hazards. Business owners (like hotels, restaurants, or car showrooms) can use Visoglide+ to dramatic effect as well – the large glass frontage can entice customers with open, panoramic displays, and the reliable sliding mechanism is built for frequent use. Importantly, these doors are engineered for British weather – excellent seals keep out drafts and rain, so your comfort isn’t compromised by all that glass. And with the high-spec glazing we offer, you won’t feel cold radiating off the glass in winter or excessive heat in summer. Many clients also enjoy the slim frames aesthetically; sliding doors generally offer thinner sightlines than bifolds at the glass joins, so if maximizing the view even when closed is a priority, Visoglide+ shines. Overall, if you’re looking for a stylish, modern alternative to French or bifold doors, Visoglide+ provides a robust, secure and visually stunning solution.

Everything you need to know about Smarts Visofold 1000 Bifolding Doors

  • Configurations: Available in 2-track or 3-track systems. A 2-track can carry up to 4 panels (2 sliding + 2 fixed), while a 3-track can carry up to 6 panels (e.g., 3 slide behind 3 fixed or all 6 stack to one side in a twin-track dual meet configuration). This flexibility allows very wide openings or a design where two-thirds of the opening can be open at once.
  • Inline vs Lift & Slide: The standard is inline sliding – you unlock and slide the door in one motion. We also offer an upgraded lift-and-slide mechanism: turning the handle lifts the door slightly off its seals, allowing ultra-smooth motion and the ability to stop it anywhere. Lift-and-slide also provides a tight seal when closed and often can give higher weather ratings.
  • Tracks and Thresholds: Robust aluminium double or triple track threshold with stainless steel or anodized running rails for longevity. The threshold can be low-profile (with slight ramp) for flush internal floors. It is fully drained – water that enters the track weep holes is channeled out. Optionally, a soft-close mechanism is available to prevent panels from slamming (good for young families).
  • Hardware: Each sliding panel has a multi-point lock engaging into the jamb (typically hooks or mushroom cams) and a secure interlock engagement. Internal locking handles come in various finishes (white, black, chrome, etc.), with exterior key-lock options. We use high-quality tandem rollers that can be adjusted for perfect alignment. For larger units, heavy-duty rollers and additional intermediate locks are used to maintain security.
  • Performance: The system is designed for exposed locations – rated to severe weather standards (in tests, up to 600 Pa water tightness and high wind loads). It’s also one of the few sliding doors in its class that is fully Document Q compliant when needed (PAS24 security with an upgraded glass unit). Thermal performance with standard double glazing meets or exceeds current regulations, and with triple glazing (up to 38 mm units) can reach extremely low U-values around 1.1 W/m²K for new builds.

With Visoglide+, you have unlimited colour choices. We offer over 200 RAL colours, including popular contemporary tones like Anthracite Grey, sleek black, or subtle white. You can also opt for dual-colour profiles (e.g., a different interior colour to match your décor) thanks to the thermal break which allows separate painting of inside and out. Additionally, Smart’s unique Sensations range of textured finishes is available – these give a tactile, matte look in shades such as Velvet Black or Antique Grey, adding a premium feel. All finishes are done in-house with advanced powder-coating for longevity. For high-traffic commercial installations or coastal homes, we can provide enhanced marine-grade coating on request. Whatever colour you envision, we can deliver a beautiful, durable finish that complements your style.

Visoglide+ sliding doors accommodate glazing up to 38 mm thick. Standard specification is a 28 mm double-glazed unit with low-emissivity coating and argon fill, which yields excellent thermal insulation. We ensure all sliding door glass is toughened safety glass (to withstand impacts). If the sliders are part of a critical area (floor-to-ceiling in a home), the glass will be laminated or toughened to meet building regs – typically we use toughened for sliding panels and can do laminated inner panes for added security if needed. Options include: Triple glazing (for ultimate energy efficiency or noise reduction), solar control glass (recommended for large south or west-facing doors to reduce solar gain – available in neutral tint that barely changes appearance), and self-cleaning glass which uses a special coating to break down dirt. We also offer integral blinds as a custom option if shading is desired without external window treatments. Each unit is factory glazed or delivered ready for quick site glazing with the Smart Quick-Glaze beads, ensuring a snug fit and easier installation.

Technical users can refer to our Visoglide+ Data Sheet (covering U-values, sizes, sightlines) and the Technical Manual for this system. Also available is an Operation & Maintenance Guide that we provide to end-users, which you can preview in the downloads. These resources will help you plan, specify, or simply learn more about the Visoglide+ doors. If you require any specific test certificates (e.g., PAS24 security test report or weather test results), please contact us – we have those documents on file and can share them upon request.
