Product Details
The DERCHI aluminium shop window is an aluminum casement window built with a 1.8MM profile thickness and 118MM frame width, incorporating an S18 multi-cavity insulation strip and DERCHI insulation strip within the aluminum frame. The glazing unit uses double tempered glass with argon gas fill in a 5mm+27A+5mm configuration separated by a PVDF aluminum strip. The window operates via outward opening or awning action using a 13-inch flat open friction hinge independently developed by DERCHI, paired with a WEHAG handle in black and silver and a WEHAGE lock point and lock seat system with a six-point locking mechanism. DERCHI independently develops and customizes transmission boxes for the WY-118L system at a factory covering 70,000+ m² with 4,000 m² showroom and 600+ employees, and can supply the complete window system including profile, hardware, accessories, glass, and finished products ready for installation.
Procurement teams should confirm the glass configuration from seven available options—single, tempered, double-glazed, triple, insulating, laminated, and frosted—and select color finishes from two PVDF options (Retro Green, Mint Gold) or ten stock colors. Ten customizable layout configurations are available including fixed panels, casement sashes, and awning openings, with optional New 48 Pack or New 88 Pack packages. Buyers should verify that products meet NFRC, AS2047, and CE certifications for project compliance, and plan for a 25-35 day delivery timeline after deposit and drawing confirmation. A 10-year quality warranty covers frame unfading, peel-off resistance, and proper hardware operation under correct use, and engineering and supervising service is provided to guide installation.
Product Features
- WY-118L model with 118mm frame width and 1.8mm profile thickness — sets wall opening rough-in dimensions and structural support sizing for each unit.
- Outward opening and awning configuration — determines interior clearance direction and rain-ventilation orientation for each opening.
- WEHAG handle available in black, silver, and antique bronze finishes — sets the interior hardware finish coordination point.
- Black six-point lock with invention patent — defines the security locking level for forced-entry resistance.
- U-factor of 0.23 and SHGC of 0.20 — determines energy code compliance and climate zone suitability.
- Sound insulation rating of 35 dB — sets the acoustic performance level for noise-exposed facade locations.
- Water tightness at 700Pa, air tightness at 1.2 m³/(m·h), and wind pressure resistance at 5K Pa — sets the exposure rating for wind-driven rain and storm conditions.
