High-Performance Thermal Break Aluminum Skylight Windows
Grandor Door Industry Co., Ltd. manufactures factory-direct aluminum skylight windows engineered for maximum daylighting, high thermal isolation, air-tight sealing, and long-term weatherproofing in modern global residential and commercial buildings.
Precision-Engineered Roof Glazing for International Projects
As an industry-leading manufacturer with over 16 years of expertise, Grandor Door Industry Co., Ltd. produces architectural aluminum skylight windows designed to fulfill rigid international standards (AS2047, CE, ASTM, NFRC). Manufactured inside our 155,000 m² smart facility, every skylight profile incorporates polyamide thermal break strips, multi-layer EPDM seals, and stepped tempered safety glass to eliminate thermal bridging and water ingress.
Whether your project requires fixed flat roof lights for modern architectural villas or electric motorized venting skylights for commercial daylighting and smoke evacuation, our engineering team provides full CAD shop drawings, custom frame colors, and structural glass load calculations.

Customizable Skylight Series
Fixed Flat Glass Roof Skylight
Designed for flat or low-pitch roofs to bring uninterrupted natural light into deep room layouts. Features flush external glass edges for rapid water runoff and zero water pooling.
- Minimalist frame sightlines
- Self-cleaning Low-E glass treatment
- High acoustic insulation up to STC 40dB
Electric Motorized Venting Skylight
Equipped with concealed 24V/110V electric actuators, smart home controls, and weather sensors that automatically close the roof window at the first sign of rain.
- Integrated rain and wind automatic sensors
- Remote control and wall switch compatibility
- Optional motorized sunshade blinds & flyscreens
Manual Awning Roof Window
Top-hung opening roof access windows designed for pitched roofs. Delivers efficient natural convection ventilation, easy manual crank operation, and multi-point perimeter locking.
- Friction stay hinges for stay-open positioning
- Continuous rubber weather stripping
- Heavy-duty security locking hardware
Fully Integrated In-House Manufacturing
Grandor Door Industry Co., Ltd. controls 100% of the manufacturing workflow under one roof — ensuring structural reliability, exact color matching, and strict quality control.
Precision Glass Tempering
Automated cutting, edge grinding, toughening, and insulated glass unit (IGU) sealing guarantee impact safety and thermal integrity for overhead roof glazing.
Qualicoat Powder Coating
High-grade surface finishing provides 20+ years of salt-spray corrosion protection, resistance against intense UV radiation, and exact RAL color customization.
Strict Pre-Shipment Inspection
Every order undergoes rigorous air infiltration, static water penetration, and structural wind pressure load testing prior to protective export crating.
Frequently Asked Questions
What safety glass setup is recommended for overhead roof skylights?
Grandor mandates toughened safety glass for the exterior pane and laminated safety glass for the interior pane (e.g. 6mm Low-E Tempered + 12Ar + 5mm+0.76PVB+5mm Laminated) to prevent glass fallout even in severe weather.
How does Grandor guarantee water tightness on flat and pitched roofs?
Our aluminum skylight frames feature continuous EPDM rubber gaskets, stepped glass edge designs, and integrated internal drainage channels to route driven rain water away cleanly.
Can skylight frame sizes and pitch mounting angles be customized?
Yes. All profiles are extruded, cut, and assembled in-house at Grandor Door Industry Co., Ltd. We engineer custom dimensions, flashing kits, and roof pitch adapters according to your building drawings.
What is the standard lead time for wholesale and project orders?
Production lead time is typically 25 to 35 days from finalized shop drawings. Fully custom wooden crate packaging ensures safe arrival at global ports.
