The Aluminum Sliding Door For Courtyards from DERCHI is engineered to connect interior living spaces with outdoor courtyards, terraces, and patios through expansive glass openings. Featuring thermal break aluminum construction and weather-resistant design, it suits high-end villas, hotels, and commercial projects requiring robust performance, wide views, and tailored aesthetics.
- Wide panels up to 4000mm width and 6000mm height for large openings
- U-value options as low as 0.28 (NFRC) for energy efficiency
- Custom glass, finish, and hardware configurations to match project specifications
- EPDM dual seals and hidden drainage for reliable weather protection
Product Details
The structural design of this aluminum sliding door for courtyards centers on a thermal break system that separates interior and exterior aluminum frames, significantly slowing heat transfer. Standard 2.2mm frame profiles in the primary series are paired with 1.8mm or equal-thickness sashes, while heavy-duty series use 8mm+21A+8mm glass and robust carriages for panel weights that push the limits of manual sliding.
Unlike light-duty residential sliders, these doors incorporate dual EPDM seals, integrated drainage channels, and silent roller systems to maintain weather tightness and smooth motion even after years of exposure. The engineering accommodates oversized glass panes, achieving a near-frameless look while meeting structural wind loads up to 4.5 kPa. Buyers who need a courtyard sliding door that balances thermal performance, large opening dimensions, and customizable finishes will find this system adaptable to architectural specifications, with project-level engineering support available for non-standard sizes.
Product Features
Thermal Break Efficiency: Polyamide strips between aluminum profiles cut heat flow, lowering U‑values to 2.3 W/(m²·K) or better, essential for energy‑conscious courtyard designs.
Large Glass Aesthetics: As a large glass sliding door, it carries double or triple glazing up to 8 mm+21A+8 mm, offering wide views while resisting thermal stress.
All-Weather Sealing: Dual EPDM gaskets and hidden drainage prevent water ingress and air leakage, backed by a 4.5 kPa wind load rating.
Silent, Smooth Operation: Multi‑wheel carriages with anti‑swing rollers glide panels over 200 kg; stainless steel bearings ensure years of quiet use with minimal wear.
Customizable Configurations: Choose 2‑track or 3‑track sliding, Low‑E or tinted glass, and powder, wood grain, or anodized finishes to match project aesthetics.
Heavy-Duty Hardware: Multi‑point locks in 304 stainless and optional electric motorization deliver security and convenience; brand‑specified hardware can be fitted.
Customizable Styles
Glass Options: Select from clear tempered, Low-E, laminated, tinted, reflective, or triple-glazed units; magnetic integrated blinds available upon confirmation.
Frame Finishes: Powder coating (standard RAL colors), anodized, wood grain transfer, or PVDF coating for enhanced weather durability—exact color matching can be discussed.
Size & Configuration: Panel widths from 580mm to 4000mm and heights up to 6000mm, subject to engineering review; 2-track or 3-track sliding systems can be proposed.
Track & Opening Style: Standard lift-slide or telescopic stacking configurations possible; confirm with manufacturer for multi-panel installations.
Custom Aluminum Door Branding: OEM/ODM services cover profile design, hardware color, and packaging to create a custom aluminum door solution for your brand.
Hardware Accessories
Multi-Point Locking: Four-side six-point lock with PAG aluminum hook and 304 stainless steel seat, delivering secure closure for wide panels.
Silent Pulley Carriage: Four-wheel or dual-row stainless steel ball-bearing pulleys with anti-swing rollers ensure smooth, quiet operation under heavy loads.
EPDM Dual Seals: Double-layer EPDM gaskets on frames and interlocking profiles maintain air and water tightness; silicone wool sealing on some series.
Hidden Drainage System: Integrated channels inside the bottom track direct water away without visible openings, keeping the sill clean.
Optional Motorization: Electric sliding mechanisms can be discussed for commercial projects requiring automated opening—control integration details subject to confirmation.
Basic Parameters
Performance Item | Available Information | Buyer Notes |
|---|---|---|
Thermal Insulation | 2.3–2.5 W/(m²·K) for thermal break models (Level 5–6); NFRC U-Factor 0.28 available on heavy-duty series. | Values depend on glass spec. Request U-value calculation for your configuration. |
Wind Pressure Resistance | 4.5 kPa (Level 8) across standard test samples. | Confirm adequacy for hurricane-prone regions; larger panels may need structural analysis. |
Water Tightness | 300–450 Pa (Level 3 to higher), varying by series. | Higher Pa rating (450) is achieved on heavy-duty models. Verify exposure category. |
Air Tightness | 4.5 m³/(m·h) (Level 6). | Tested per EN 12207; actual performance affected by installation quality. |
Sound Insulation | 30–35 dB (Level 3–higher) with standard glass. | Acoustic laminated glass can increase reduction; discuss if >35 dB required. |
