Fully Glazed Aluminium External Door

A: SGL fully glazed aluminium external doors are engineered for a wide range of climate conditions from tropical to cold temperate zones. The 6063-T5 aluminium frame is inherently corrosion-resistant and performs reliably in humidity levels up to 95% RH. EPDM weatherstripping maintains elasticity across temperatures from -40°C to +120°C. For specific climates: Hot/humid climates (tropical, coastal): Specify anodized finish (Class AA15) or marine-grade powder coating (1,000+ hour salt spray), SS316 hardware for chloride resistance, and Low-E glass to reduce solar heat gain. Cold climates: Specify double glazing (5+20A+5mm) with argon filling and Low-E coating to achieve U-values as low as 2.2 W/m²K. Ensure threshold includes thermal break to prevent condensation. High-wind/exposed locations: Specify 35mm frame profile, laminated glass (8+1.52PVB+8mm), and multi-point locking (5 points). Wind load resistance up to Class C4 (2,400 Pa) is achievable. Urban/polluted environments: Powder coating (≥80μm) provides excellent resistance to acid rain and atmospheric pollutants. Annual cleaning with mild detergent is sufficient.

Custom cut-outs, drilled holes, and notches for handles and locks. Pre-production samples are available for large orders to verify color and finish before full production.

A: Yes - SGL fully glazed aluminium doors can be configured to meet major international energy efficiency standards. Thermal Performance: With double glazing (5+12A+5mm): U-value 2.2–2.8 W/m²K. With Low-E double glazing: U-value as low as 2.0 W/m²K. These values meet or exceed requirements for EN ISO 10077-2 and GB/T 8484. Green Building Compatibility: LEED v4.1 - U-values ≤2.5 W/m²K contribute to EA Credit: Optimize Energy Performance. BREEAM - Compatible with Ene 01 credits for building envelope performance. Passive House - Triple glazing and thermal break threshold options available for ultra-low U-value requirements. Certifications: Manufacturing under ISO 9001:2015 quality management system. Test reports for air permeability (EN 12207), water tightness (EN 12208), and wind load (EN 12210) available from third-party laboratories (SGS, BV, Intertek). Project-specific U-value calculations and energy performance reports can be provided upon request.

A: All glass used in SGL fully glazed doors complies with international safety standards. Tempered Glass (Single Glazing): Meets EN 12150 (European standard for thermally toughened soda lime silicate safety glass) and ANSI Z97.1 (American standard for safety glazing materials). Impact resistance: 4–5 times stronger than annealed glass of equivalent thickness. Breakage pattern: fractures into small, relatively harmless granular pieces. Laminated Glass: Meets EN 14449 (laminated safety glass) and AS/NZS 2208. PVB interlayer thickness options: 0.76mm, 1.14mm, 1.52mm. Post-breakage: glass fragments adhere to interlayer, preventing fall-out. UV blocking: 99% of harmful UV radiation filtered. Double Glazing: Inner and outer lites are both tempered for safety. Spacer bar options: aluminium warm-edge spacer or Swisspacer for improved thermal performance. Argon gas filling (90%+) available to reduce convective heat transfer. For projects in hurricane-prone regions or requiring enhanced security, SGL offers laminated glass with thicker PVB interlayers and reinforced frame anchoring.

A: SGL fully glazed doors are delivered pre-hung in the frame for efficient installation. Key requirements include: Opening Preparation - Rough opening should be 15–20mm larger than the frame dimensions in both width and height. Opening must be structurally sound, level, and plumb (tolerance ±3mm per meter). Sill must be flat and capable of supporting the door weight (typically 40–80 kg depending on size and glass). Waterproof membrane should be applied to the opening perimeter before frame installation. Frame Installation - Frame is positioned in the opening and leveled using shims. Fix through pre-drilled frame anchor holes at 400–600mm centers. Maximum frame distortion after fixing: ≤2mm across the diagonal. Glazing and Sealing - Glass is installed with setting blocks and edge clearance of 5–8mm per side. Apply neutral-cure silicone sealant to the glass-to-frame interface. Install EPDM compression gaskets on both interior and exterior sides. Apply perimeter sealant (polyurethane or silicone) between frame and wall. Threshold - For weather-exposed entrances, specify a thermally broken threshold with drainage slots. Threshold height: typically 15–25mm above finished floor level for external doors. SGL provides detailed installation drawings (PDF + DWG), video guidance, and remote technical support. On-site installation supervision is available for China-based projects.

A: SGL fully glazed aluminium doors are low maintenance, with the following recommended care schedule: Every 3 months: Clean glass panels with standard glass cleaner and soft cloth. Wipe aluminium frames with mild soap solution and damp cloth. Remove debris from threshold drainage slots. Every 6 months: Check EPDM weatherstripping for compression, tears, or hardening. Lubricate hinges and lock mechanisms with silicone-based spray. Check and tighten any loose screws on hardware. Every 12 months: Inspect perimeter sealant between frame and wall; reapply if cracked or degraded. Check powder coating or anodized finish for scratches or damage; touch-up kits available. Verify door alignment and adjust hinges if gaps are uneven. Every 3–5 years: Replace EPDM weatherstripping if compressed or perished (replacement kits available). Professional inspection recommended for commercial high-traffic installations. What NOT to do: Do not use abrasive cleaners, steel wool, or solvent-based chemicals on powder-coated or anodized surfaces. Do not pressure-wash directly at gasket interfaces. Do not apply paint or film coatings without consulting SGL. Compared to timber doors (re-stain every 2–3 years) or steel doors (rust treatment required), SGL aluminium glazed doors require minimal ongoing maintenance.

A: Yes - SGL specializes in oversized fully glazed aluminium doors for architectural statement entrances and commercial atriums. Maximum Capabilities: Single leaf: up to 1,500mm width × 3,200mm height (1.5m × 3.2m). Double leaf: up to 3,000mm width × 3,200mm height (3.0m × 3.2m). Fixed sidelight panels: up to 1,500mm width × 3,200mm height per panel. Engineering Considerations for Oversized Doors: Glass thickness - Doors >2.5m height or >1.2m width require 10–12mm tempered glass or laminated glass (8+1.52PVB+8mm) for structural safety. Hinge specification - Three or more heavy-duty SS304 hinges (≥100 kg/pair rating) for tall doors; pivot hinge systems recommended for doors >2.8m height. Frame profile - 35mm frame width is mandatory for doors >2.4m height to provide sufficient structural rigidity. Wind load - Oversized doors in exposed locations require Class C4 wind load rating with laminated glass. Threshold - Reinforced threshold with thermal break and load-bearing capacity ≥150 kg/m recommended for wide double-leaf configurations. Lead Time for Custom Sizes: Standard custom sizes (within max capability): 15–25 working days. Ultra-large or structurally complex designs: 25–35 working days after engineering approval. All oversized door orders require SGL engineering review and signed technical drawings before production.
