Application of Sliding Window
Residential buildings
Sliding windows don't take up interior or exterior opening space, making them ideal for small spaces in kitchens, living rooms, or bedrooms near furniture. Large glass areas provide ample natural light, creating a bright and comfortable interior. Double or triple track designs achieve 50%–66% ventilation area, and with independent sliding screens, they prevent insects from entering, enhancing the living experience and security.
Commercial space
Durable sliding window structures and roller tracks can withstand high-frequency opening and closing, making them ideal for shops, offices, or restaurants. Large glass windows enhance visibility and attract customers, while high-quality anti-pry locks and deepened track grooves ensure security. Low maintenance costs make them suitable for rental or high-traffic commercial environments.
Industrial and storage buildings
Sliding windows can withstand the weight of large window sashes, meeting the opening requirements of factory and storage buildings. The multi-track design ensures good natural ventilation, while EPDM sealing strips and multi-cavity frames enhance airtightness, effectively blocking dust and particulate matter. The aluminum alloy and tempered glass structure is corrosion-resistant and impact-resistant, suitable for long-term use in industrial environments.
High-rise buildings and coastal areas
The horizontal sliding design of sliding windows is safer in strong winds, making them less prone to being blown open. Multiple locking points and thickened profiles improve wind pressure resistance. Coastal buildings use anodized or fluorocarbon-coated aluminum, which is highly corrosion-resistant. Combined with triple sealing strips and built-in drainage channels, it effectively prevents backflow of heavy rain, keeping the interior dry and safe.

Sliding Window Solution
Deslano's Sliding Window Solution is designed for residential, commercial, and engineering projects, with enhancements based on real-world usage scenarios in its structural design, insulation performance, and hardware systems. Our solutions focus not only on aesthetics but also on sealing, weather resistance, smooth operation, and project adaptability, ensuring stable performance across different climates and building types.
1. Structural Engineering Design for Long-Term Stable Operation
Deslano sliding windows utilize a double-track load-bearing structure. The lower track is made of thickened aluminum profile (1.6–2.2mm optional), coupled with concealed drainage holes for rapid drainage and backflow prevention during heavy rain.
The window sash frame is precisely CNC-cut and reinforced with 45° or 90° corner brackets, ensuring it remains stable and undeformed even after long-term opening and closing. The tracks feature a wear-resistant anodized finish and silent rollers, allowing the window sash to slide smoothly even during high-frequency operation.
2. High-Performance Sealing System for Enhanced Sound Insulation and Airtightness
For high-rise buildings and windy areas, Deslano offers a triple sealing system:
EPDM air-cushioned sealing strips effectively prevent air infiltration;
A double-layer composite design of weatherstripping and adhesive strips on the track sides enhances the barrier effect during sliding;
A multi-point locking structure at the window sash closure ensures a tighter seal.
Third-party testing shows the following for the entire window:
Airtightness: ≤0.6 m³/(m·h)
Sound Insulation: 30–35 dB (upgradeable to 40 dB)
Ideal for use near roads, commercial districts, and high-rise residential buildings.
3. Double/Triple Low-E Glass System for Enhanced Energy Efficiency
Sliding Window Solution Configurable Options:
5+9A+5 / 5+12A+5 Double Insulating Glass
5+9A+5+9A+5 Triple Insulating Glass
Optional Argon Gas Filling, Warm Edge Warm Spacer
The overall window U-value can be achieved at 1.9–2.2 W/m²·K, effectively reducing indoor heat loss and making it suitable for residential, villa, and commercial spaces in extremely cold or hot regions.
