Custom Glass Vertical Sliding Windows

I. Core Features and Data

Efficient Space Utilization

Vertical sliding windows open by sliding up and down, eliminating the need for lateral movement. They can open up to 50%-80% of the window area. For example, a 1.5m wide x 2m high window provides an effective ventilation area of 1.2m2. Aluminum Sliding Windows are particularly suitable for space-constrained locations such as balconies, kitchens, or small bedrooms.

Sealing and Soundproofing

Employing a multi-point locking system and a fully sealed design, they achieve airtightness levels 6 (GB/T 7106-2019) and watertightness levels 4, meeting the national standard for protection against moderate to heavy rain. Double-glazed insulating glass (5mm glass + 12mm insulating layer + 5mm glass) can reduce noise by 25-30dB. Upgrading to triple-glazed or laminated glass can achieve noise reduction of 35-40dB.

Operational Ease

Equipped with a concealed spring balance system or electric drive, the manual opening force is ≤50N (compliant with EU EN 13126 standards), making it easy for both elderly and children to operate. The electric version supports remote control, mobile app, or smart home system integration, with a response time of ≤0.5 seconds, making it suitable for high-rise buildings or hard-to-reach window locations.

II. Material Properties and Performance Comparison

Aluminum Alloy

Advantages: Aluminum Alloy Windows offer high strength (wind pressure resistance level 9), corrosion resistance (salt spray test ≥1000 hours), a variety of surface finishes (anodizing, fluorocarbon spray coating, wood grain transfer), and a service life of over 20 years.

Limitations: High thermal conductivity (203W/m·K), requiring thermal insulation strips (PA66 + GF25) to reduce energy consumption.

Applicable Scenario: High-rise buildings, humid coastal areas, and modern minimalist residences.

UPVC (Ultra-PVC) Material

Advantages: Excellent thermal insulation (thermal conductivity 0.16 W/m·K), 30%-50% cheaper than aluminum alloy, lightweight (approximately 1/3 of aluminum alloy), suitable for retrofitting old windows.

Limitations: Poor heat resistance (long-term operating temperature ≤ 80°C), and may yellow and discolor under prolonged UV exposure.

Suitable for: Low-temperature regions, affordable housing, and rental apartment renovations.

Aluminum-Wood Composite Material

Advantages: Combining the strength of aluminum with the warmth of wood (solid wood veneer has a thermal conductivity of 0.04-0.2 W/m·K), resulting in a premium, natural appearance and enhanced sound insulation.

Limitations: High cost (50%-80% higher than aluminum alloy), requiring regular maintenance (e.g., reapplying wood wax oil every 3-5 years).

Suitable for: Villas, high-end commercial spaces, and Nordic or Japanese-style interiors.

Key Reference Data:

Aluminum alloy window frame thickness is recommended to be ≥ 2.5mm (National Standard GB/T 8478-2020). UPVC profiles are recommended to have ≥ 5 cavities for enhanced insulation.

The heat transfer coefficient (K value) of double-glazed insulating glass is 2.7-3.0W/(m²·K). Triple-glazed, two-cavity glass can reduce this to 1.8-2.2W/(m²·K), significantly improving energy efficiency.

III. Selection Guide: Four-Step Decision-Making Method

Choose Based on Climate Conditions

Cold Regions: Prefer aluminum-wood composite or UPVC with low-emissivity (Low-E) glass, with a U value (heat transfer coefficient) ≤ 1.5W/(m²·K) to reduce winter heat loss.

Humid and Hot Regions: Aluminum alloy with insulating glass, equipped with concealed drain holes (discharge rate ≥ 300ml/min) to prevent rainwater backflow. Coastal Areas: Aluminum alloy surface treatment must meet AAMA 2605 standards (fluorocarbon spray coating thickness ≥ 35μm) and resist salt spray corrosion.

Choose Based on Functional Requirements

Soundproofing Priority: Triple-glazed, double-chambered glass + laminated glass (6mm + 1.14PVB + 6mm + 12mm hollow glass + 6mm), achieving a noise reduction of 35-40dB.

Security and Anti-theft: Equipped with a Class C lock cylinder and pry-resistant steel plate, glass thickness ≥ 8mm (single pane) or ≥ 6.38mm (laminated), certified by the Ministry of Public Security.

Fireproofing Requirements: Select Class C fire-resistant glass (fire resistance ≥ 60 minutes) with stainless steel hardware to comply with fire regulations.

Control Costs Based on Budget

Economical: UPVC + single-glazed glass, suitable for rentals or short-term use.

Mid- to High-End: Aluminum alloy + double-glazed glass, balancing performance and cost.

Luxury: Aluminum-wood composite + triple-glazed, double-chambered glass, suitable for high-end residential or commercial spaces.

Confirm according to installation conditions.

Custom aluminum windows must have a dimensional tolerance of ≤5mm (height/width). Otherwise, on-site adjustments or rework will be required.

When renovating existing windows, the wall structure's load-bearing capacity must be confirmed (windows weigh approximately 40-80kg per square meter) to avoid safety hazards caused by excessive weight.

IV. Customization Options and Value-Added Services

Size and Shape Customization

Non-standard sizes are supported (minimum 300mm x 300mm, maximum 3000mm x 2400mm). Accurate measurements (with a tolerance of ≤2mm) are required.

Special-shaped windows (such as curved, trapezoidal, and triangular) will incur an additional fee of 15%-30%, and the production cycle will be extended by 3-5 days.

Glass Function Upgrades

Energy-saving options: Low-E glass (light transmittance ≥70%), argon-filled insulating glass (increases thermal insulation by 10%-15%).

Safety options: Dimmable glass (transmittance adjustable from 10% to 80%), and self-cleaning glass (surface coating decomposes stains). Decorative Types: Changhong Glass (light-transmitting but not shadow-transmitting), Wired Glass (combining safety and artistic design), Color-coated Glass (reflectivity 10%-40%).

Hardware System Selection

Imported brands have a lifespan of over 100,000 cycles, while high-quality brands have a lifespan of approximately 50,000 cycles.

The electric opening system requires a reserved power supply (220V or DC 24V) and supports mobile app control, making it suitable for smart home environments.

Color and Surface Treatment

Aluminum Alloy: Powder coating (over 200 color palettes available), wood grain transfer printing (simulation accuracy ≥ 95%), and electrophoretic coating (smooth and corrosion-resistant surface).

UPVC: Co-extruded color profiles (film thickness ≥ 0.2mm), weather-resistant for 10 years without fading, and supports two-color combinations (e.g., white exterior, wood grain interior).
