Technical Specification for Glass and Aluminium Doors: Sliding, Pivot, and Entrance Systems
Understanding the Core Components of High-Performance Glass and Aluminium Doors
High-performance glass and aluminium doors are defined by three integrated components: the thermally broken aluminum door frames, the high-specification insulated glass unit (IGU), and the heavy-duty hardware system designed for high-cycle use and weather resistance.
The Role of Aluminum Door Frames
The aluminum door frames provide the structural backbone for the system. For exterior applications, the frame must incorporate a robust thermal break to prevent heat transfer and condensation. This is non-negotiable for meeting modern energy codes.
The Importance of Glazing
The glass itself is a critical component. Project specifications must detail the required U-factor, Solar Heat Gain Coefficient (SHGC), and visible light transmittance (VLT). For large-format systems, safety glass (tempered or laminated) is mandatory.
How Do Aluminum Sliding Glass Doors Compare to Pivot Entry Doors?
Aluminum sliding glass doors prioritize maximizing glass area and minimizing operational complexity for very wide openings, while a pivot entry door is specified for its dramatic aesthetic, allowing for oversized, heavy panels that create a grand, balanced entrance.
1. Aluminum Sliding Glass Doors
Aluminum sliding glass doors are the workhorse for maximizing views and creating wide, operable facades.
•Key Advantage: They offer the slimmest sightlines and the highest glass-to-frame ratio among large-format operable systems. Modern lift-and-slide hardware allows for smooth operation of panels weighing hundreds of kilograms.
•Application: High-rise residential balconies, hotel facades, and commercial spaces requiring minimal visual interruption.
2. Pivot Entry Door Systems
A pivot entry door system is a statement piece, where the door rotates on a vertical axis (pivot point) rather than traditional side hinges.
•Key Advantage: Allows for the use of massive, oversized panels (up to 3 meters wide and 5 meters high) that would be impossible to operate on standard hinges. The pivot mechanism handles the weight and provides a unique, balanced opening motion.
•Application: Main entrances for corporate headquarters, luxury residential villas, and high-end retail spaces where a dramatic, oversized glass pivot door is required.
| System Type | Primary Mechanism | Max Panel Size | Weather Sealing | Ideal Project Priority |
| Sliding Doors | Rollers on Track | High (Maximized Width) | Good (Best with Lift-and-Slide) | Views, Wide Openings, Thermal Performance |
| Pivot Entry Door | Vertical Axis Rotation | Extreme (Maximized Height/Weight) | Medium (Requires specialized perimeter seals) | Aesthetic Impact, Oversized Entrance |
What Mistakes Should Be Avoided in Aluminium Door and Window Projects?
Common mistakes include underestimating performance requirements, unclear specifications, prioritizing lowest cost over suitability, and overlooking installation and documentation support. These issues can lead to compliance risks, on-site delays, and long-term performance problems.
1. Assuming one system fits all projects
Project conditions vary significantly by building height, location, and exposure. Using the same aluminium door or window system across different project types can result in inadequate wind, water, or structural performance.Confirm project-specific performance requirements early and select systems based on verified test data rather than residential assumptions.
2. Incomplete or inaccurate specifications
Custom products are manufactured strictly according to provided dimensions and requirements. Missing or unclear information often leads to fabrication errors or site incompatibility.Use detailed shop drawings, verify all dimensions, and clearly define opening direction, tolerances, and special requirements before production.
3. Focusing on price instead of lifecycle suitability
Lower upfront cost may involve reduced profile thickness, lower-grade hardware, or simplified configurations that affect durability and long-term operation.Evaluate aluminium doors and windows based on performance, service life, and project risk—not price alone.
4. Overlooking installation and after-sales coordination
Even well-designed systems can fail if installation requirements are not properly addressed or supported.Confirm installation guidance, technical support availability, and spare parts policies before order confirmation.
5. Missing compliance documentation
Lack of test reports or technical documentation can delay approvals and inspections during construction.Request all required certifications, test reports, and technical files as part of the procurement process.
