Aluminum Louver Windows Manufacturer China Factory Price Glass Blade Ventilation
1. System Overview — Nature’s Ventilation
The Aluminum Louver Window — also known as the jalousie window — uses parallel glass blades that tilt open to capture prevailing breezes while shielding rain. As a premier manufacturer in China, Richocean engineers louver windows with 6063-T6 frames, tempered glass blades, and SS316 pivots, at factory-direct prices.
2. Core Material Science — 6063-T6 Frames
The frame profile carries the blade assembly and pivot loads. Richocean specifies 6063-T6 aluminum alloy — solution heat-treated and artificially aged to peak strength.
Blade frames are extruded 6063-T6 channels with captive gaskets, holding each tempered glass blade securely at any tilt angle.
3. Glass Blade System — Tempered & Tiltable
The defining feature of the louver window is its parallel blade system:
- Blade sizes: 100–200mm wide × up to 1,200mm long
- Tempered glass: 6mm minimum, 620°C heat treatment, EN 12150
- Tilt range: 0° closed to 70° open via lever or gear handle
4. SS316 Pivots & Hardware
Each blade pivots on precision bearings. Richocean specifies SS316 stainless steel:
- SS316 composition: molybdenum 2–3% resists chlorides; yield 205 MPa
- Pivot bearings: nylon-lined for smooth, silent operation
- Durability: 30,000+ tilt cycles without play
5. Ventilation & Rain Shielding
The angled blades deliver the unique ventilation-plus-shielding performance:
- Updraft design: blades angle upward, deflecting rain while air flows through
- Ventilation area: up to 70% of the opening at full tilt
- Privacy control: blade angle adjusts light and sightlines

7. Technical FAQ
Q: What is the maximum blade length for an aluminum louver window?
A: Typical maximum is 1,200mm per blade; longer openings are divided into stacked louver sections with intermediate mullions.
Q: How do louver windows perform in heavy rain?
A: The upward blade angle deflects rain; closing blades to a steeper angle during storms provides near-full shielding while retaining airflow.
Q: Are louver windows secure?
A: Closed blades interlock with the frame; optional locking handles and fixed-position stops add resistance for ground-floor applications.
8. China Market Ranking — Why Richocean is #1
Richocean ranks #1 in China for louver window export volume. The Foshan factory runs automated CNC machining and powder-coating lines with 80,000m² annual capacity, serving Southeast Asia, the Middle East, and North America. Factory-direct pricing runs 30–50 percent below Western distributors.
