The SL182 thermal break sliding door series represents a premium tier in aluminum fenestration, engineered for high-end residential and commercial projects that demand exceptional thermal performance, structural rigidity, and panoramic views. As a leading sliding door supplier, ALPES designs this series with meticulous attention to every engineering detail — from profile wall thickness to sealing systems — delivering a product that meets international building standards while offering outstanding value.
The SL182 series is built on 6060-T66 grade aluminum profiles — a high-precision alloy known for its excellent strength-to-weight ratio and superior corrosion resistance. The main load-bearing profiles feature a wall thickness of 2.0mm, with critical structural zones locally reinforced up to 3.0mm, ensuring robust wind pressure resistance and long-term structural stability.
| Parameter | Two-Track (126) | Three-Track (182) |
|---|---|---|
| Frame Wall Width | 126mm | 182mm |
| Profile Thickness | 2.0mm (up to 3.0mm reinforced) | 2.0mm (up to 3.0mm reinforced) |
| Profile Grade | 6060-T66 | 6060-T66 |
| Glass Sash Thickness | 55mm | 55mm |
| Frame Width | 36mm | 36mm |
| High Track Height | 43mm | 43mm |
| Low Track Height | 8mm | 8mm |
The series offers two sash width configurations — a 96mm version for maximum structural capacity and a 75mm narrow-edge version for ultra-slim panoramic views. Both options maintain the same high-grade aluminum construction and thermal break technology, allowing architects and homeowners to choose based on aesthetic preferences and performance requirements.
At the heart of the SL182 series is the PA66GF25 thermal break system — a glass-fiber-reinforced polyamide barrier that interrupts heat transfer between the interior and exterior aluminum profiles. This multi-chamber thermal break design significantly reduces thermal conductivity, helping buildings maintain stable indoor temperatures year-round and reducing HVAC energy consumption.
The thermal break is complemented by a continuous four-sided sealing system, with sealant applied between the top track and frame for true full-seal performance. This dual-matrix sealing approach not only enhances thermal efficiency but also provides superior air and water tightness, ensuring the door performs reliably even in extreme weather conditions.
The SL182 series accommodates 55mm thick glass sashes, supporting a wide range of insulated glass configurations to meet different performance and aesthetic needs. For projects requiring enhanced thermal performance, 27A super large insulating glass with inert gas filling is available, further reducing U-values and improving overall energy efficiency.
Various glass tints and styles can be customized to match project specifications, including clear, tinted, reflective, and low-emissivity (low-E) coatings. This flexibility makes the series suitable for diverse climate zones and architectural styles, from sun-drenched coastal regions to cold northern climates.
The SL182 thermal break sliding door supports both standard sliding and lift-sliding operation modes, giving users flexibility in how they interact with the door. The multi-point locking system features stainless steel locks housed in precision-cast reinforced casings, providing robust security while maintaining smooth, effortless operation.
For screen options, the series is compatible with 80# black or gray stainless steel mesh, offering insect protection without compromising visibility or airflow. The seamless frame design, with its pressure-line-free smooth surface, creates a clean, modern aesthetic that complements contemporary architectural styles.
One of the standout features of the SL182 series is its patented eave-style waterproof design, which effectively channels rainwater away from the interior. The bottom track incorporates a water-blocking edge design, and butyl rubber waterproof gaskets at frame-sash joints create an additional barrier against moisture infiltration.
The interchangeable drip-eave inserts further enhance water management, ensuring that even during heavy rainfall, water is efficiently drained away from the building envelope. This attention to waterproofing detail is particularly valuable for coastal projects and regions with high precipitation.
The SL182 series delivers impressive size capabilities, with single sash dimensions reaching up to 2.5 meters in width and 3.0 meters in height — providing approximately 7 square meters of daylight area per panel. This large opening capacity makes the series ideal for creating seamless indoor-outdoor transitions in luxury villas and modern residential projects.
As a professional sliding glass door manufacturer, ALPES understands that sliding door sizes vary significantly across projects. The SL182 series offers flexible panel configurations with two-track and three-track options, allowing for 2-panel, 3-panel, or 4-panel arrangements to suit different opening widths and architectural layouts.
The SL182 series is available in four standard colors to suit a variety of design aesthetics: Ice Cream White for a clean, modern look; Aurora Gray for bold, contemporary contrast; Starry Sky Gray for sophisticated medium-tone elegance; and Brown Coffee for warm, classic appeal. Custom color matching is also available for projects requiring specific RAL or custom finishes.
The SL182 thermal break sliding door series is engineered for high-end residential and commercial applications where performance, aesthetics, and durability are paramount. Typical installations include luxury villa patios, modern apartment balconies, hotel lobbies, restaurant dining areas, and commercial storefronts.
With its strong wind pressure resistance — enhanced by 3.0mm local reinforcement in critical zones — the series is particularly well-suited for coastal areas and high-rise buildings that face challenging wind conditions. The thermal break technology also makes it an excellent choice for projects targeting energy efficiency certifications and green building standards.
The SL182 thermal break sliding door series combines premium 6060-T66 aluminum construction, PA66GF25 thermal break technology, and precision-engineered sealing systems to deliver a high-performance solution for modern building projects. With flexible configurations — including two-track/three-track layouts, 96mm and 75mm sash options, and customizable glass and finishes — the series adapts to diverse architectural visions without compromising on quality or performance.
Backed by ALPES's 100,000 m² manufacturing facilities in Foshan and Zhaoqing, and produced according to international building standards, the SL182 series represents a reliable choice for architects, developers, and homeowners seeking a premium thermal break sliding door solution that delivers on both form and function.
