This aluminium clad casement window is built for project buyers who specify aluminium clad windows in their building projects. Products meet NFRC, AS2047, and CE certifications, and the manufacturer will make the product tested and certified if a project requires additional compliance.
- Price is based on the buyer's specific requirement, so configuration must be defined before quotation.
- Opening way is outward opening / awning, fitting facades where outward-swinging sashes are acceptable.
Product Details
The aluminium clad casement window is built with an aluminum profile at 1.8 mm thickness and a 118 mm frame width, operating through outward opening or awning action supported by a WEHAG hinge and a 13-inch flat open friction hinge independently developed by DERCHI. The sash is secured by a WEHAGE lock point and lock seat system with a six-point locking mechanism, and the standard glass unit uses double tempered glass with argon gas (5 mm + 27A + 5 mm) separated by a PVDF aluminum strip, with a DERCHI standard insulation strip and a WEHAG handle in black and silver finishes. Buyers can verify construction and hardware details in person at the supplier's 4,000 m² showroom.
Procurement teams should confirm glass selection from seven available configurations, layout from ten customizable WY-118L series options, and color finish from two PVDF and ten stock choices, as price is based on the buyer's specific requirement and delivery runs 25-35 days after deposit and drawing confirmation. The supplier can provide the complete window system including profile, hardware, accessories, glass, and finished products ready for installation, offers engineering and supervising service to guide installation, provides a 10-year quality warranty covering frame unfading, hardware, and accessories, and products meet NFRC, AS2047, and CE certifications.
Product Features
