Product Features
WY-75 Series aluminum casement window with 75MM frame width and 1.8MM profile thickness — determines structural load suitability for high-rise commercial and super high-rise residential projects.
Outward opening and awning configuration — informs placement where inward swing would conflict with interior space or furnishings.
Multi-cavity frame structure with high-performance sealed glazing system achieves 35 dB sound insulation — affects selection for noise-sensitive environments.
Style configurations include single sash, double sash, multi-panel assemblies, angled top designs, geometric shapes, and hexagonal windows — determines which architectural opening shapes can be matched.
DERCHI-developed hardware — baseless safety handle, 12-inch heavy-duty hinge, lock point and lock base, stainless steel friction hinge with multiple pivot points, ergonomic lever handles with two base style options — informs hardware compatibility within the WY-75 profile system.
Standard DERCHI insulation strip paired with argon-filled double tempered glass — affects thermal performance selection for climate-specific projects.
Price varies by shop drawing/window schedule, frame color, glass type/thickness/color, and argon option — determines cost scope for project-specific configurations.

What should buyers prepare for volume procurement?
Quotation requires drawings, dimensions, quantity, color, and glass type. Delivery runs 25-35 days after deposit and drawing confirmation.
Which commercial terms and documents must be confirmed before quotation?
Confirm project drawings, dimension schedules, order quantity, color specifications, and glass type requirements with the supplier before requesting quotation.
Can products be certified to specific standards?
Products meet NFRC, AS2047, and CE standards. Additional testing and certification can be arranged if the buyer requires.
Is the product suitable for OEM/ODM partnerships?
The product is suitable for OEM/ODM and distributor partnerships.
