Commercial Doors

 Commercial aluminium doors in 2026 are engineered for high-traffic durability, strict thermal compliance, and advanced security. Unlike residential doors, commercial systems must often integrate with building management systems (BMS) and meet specific accessibility (DDA) requirements 

The SmartWall system is a high-performance, thermally broken shopfront and door solution designed specifically for heavy-traffic commercial environments. Unlike standard residential doors, SmartWall is engineered for durability in settings like schools, colleges, hospitals, and retail outlets.

It is often cited as one of the first fully thermally broken commercial screen and entrance systems in the UK to achieve high-level security certifications.

• Thermal Performance: Features a 100mm frame depth with a polyamide thermal break, significantly reducing heat loss compared to traditional non-thermal shopfronts.
  
• Safety First: Includes anti-finger trap stiles as a standard safety feature, which is essential for educational and public buildings to prevent injuries.
  
• Versatile Configurations: Supports swing, hinged, and even automatic sliding doors. It can be integrated into large ground-floor "screens" (fixed glazing walls).
  
• Glazing Options: Can accommodate double or triple glazed units ranging from 24mm to 32mm in thickness.

The Smart Shopline system is the industry standard for non-thermally broken aluminium shopfronts and commercial entrances. While the SmartWall (which we just looked at) is designed for high energy efficiency, Shopline is the "workhorse" of the UK high street—favored for its affordability, modularity, and rapid installation.

It is primarily used for ground-floor retail units, car showrooms, and internal screens where thermal insulation is less of a priority than cost and durability.

• Modular Construction: Designed as a "ladder frame" system, meaning it can be quickly assembled on-site to create large expanses of glass.
  
• Non-Thermal: Unlike the SmartWall, Shopline does not have a polyamide thermal break. This makes it more cost-effective but less suited for heated residential spaces.
• Flush Glazing: Offers a clean, modern look where the glass sits flush with the frame, maximizing the "display window" area for retailers.
  
• Integrations: Easily accommodates various entry types, including manual swing doors, automatic sliding doors, and even overhead concealed closers.

The Smart Alitherm Heritage 60 is the dedicated door system within the Heritage range, launched to provide a high-performance, thermally efficient entrance solution that mirrors the ultra-slim look of traditional steel "Crittall-style" doors.

While the Alitherm Heritage window system is often used for smaller openings, the Heritage 60 is specifically engineered for single and double (French) door applications, offering the structural integrity needed for larger glass panes.

• Signature Slim Profiles: Features a typical sightline of just 59mm, replicating the delicate proportions of Victorian and Art Deco steel doors.
  
• Authentic Lock Box: Includes a dedicated "lock box" detail—a classic feature of traditional steel doors that houses the handle and locking mechanism.
  
• Matching Hardware: Supports a full suite of heritage-style ironmongery, including Monkey Tail and Bulb handles, as well as Art Deco-inspired lever handles.
  
• Flush Finish: Designed with a flush-fitting sash and frame for a clean, period-correct aesthetic.
