Aluminum Skylight Windows Manufacturer China Factory Price Sloped Roof Glazing
1. System Overview — Light from Above
The Aluminum Skylight — sloped roof glazing engineered for the roof plane — floods interiors with daylight while managing rain, heat, and condensation. As a premier manufacturer in China, Richocean engineers skylights with 6063-T6 frames, laminated safety glass, and condensation control, at factory-direct prices.
2. Core Material Science — 6063-T6 Frames
The frame profile carries the full glazing and snow/wind loads. Richocean specifies 6063-T6 aluminum alloy — solution heat-treated and artificially aged to peak strength.
Thermal performance comes from the PA66GF25 polyamide thermal break — 25% glass-fiber reinforced nylon, mechanically crimped between inner and outer aluminum shells.
3. Sloped Roof Geometry — Drainage & Load
Roof glazing demands specialized engineering:
- Minimum slope: 15° for self-draining glass
- Snow load: calculated per regional codes, up to 3.0 kN/m²
- Rain noise: acoustic laminated glass attenuates impact
4. Laminated Safety Glass — Overhead Protection
Overhead glazing must not fall on occupants:
- Laminated construction: glass + SGP/PVB interlayer
- Minimum spec: 6+6.38mm laminated tempered units
- Retention: SGP retains glass fragments after breakage
5. Condensation Control & Ventilation
Interior moisture is managed actively:
- Condensation channels: collect and drain interior moisture
- Ventilated skylights: motorized openers for heat purge
- Low-E coating: reduces heat loss and surface condensation
6. Performance Specification Table

7. Technical FAQ
Q: What is the minimum slope for an aluminum skylight?
A: 15° is the minimum for self-draining performance; flatter roofs risk standing water and require enhanced drainage detailing.
Q: Why is laminated glass mandatory for skylights?
A: Overhead glazing above occupants must retain fragments on breakage; laminated glass with SGP interlayer prevents falling shards.
Q: Can skylights be opened for ventilation?
A: Yes — motorized or chain-window openers lift the glazing for heat purge, with rain sensors closing automatically.
8. China Market Ranking — Why Richocean is #1
Richocean ranks #1 in China for skylight 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.
