Skylights and glass rooflights

II. Core Material Selection Principles for Skylights
Safety‑first laminated glass: prevents spontaneous breakage, protects against falls from height, and remains intact upon shattering.
Large spans / High altitudes: thickened laminated glass, ultra-clear laminated glass, laminated insulated glass
Hot and stuffy from afternoon sun: Must be paired with Low-E, colored glaze, or coated insulation.
Loud noise and street-facing: Use thickened PVB/SGP laminated glass to enhance sound insulation.
Special-shaped curved glass:选用 bent laminated glass, hot-bent laminated glass

III. Standard Solutions for Different Scenarios
Option 1: Standard Small Skylight / Canopy (for residential use, entrance halls, or small courtyards)
Recommended configuration: 6+6 double-layer tempered laminated glass / 8+8 double-layer tempered laminated glass
Applicable to: small spans, low-rise structures, moderate budgets, and projects prioritizing safety, rain protection, and natural lighting.
Advantages: high cost-performance, explosion-proof and fall-resistant, hail-resistant, and shatters without fragmenting.

Option 2: Atrium / Large-Span Public Skylights (Shopping Malls, Hotels, Office Buildings)
Recommended configuration: 8+8 SGP laminated glass / 10+10 PVB laminated glass
Optional: Laminated + Hollow Composite, Ultra-White Laminated
Applicable to: large spans, high pedestrian traffic, and elevated public areas.
Advantages: high strength, excellent wind-pressure resistance, clear transparency without green tint, and a high safety rating.

Option 3: A specialized skylight designed for severe west-facing sun exposure and thermal insulation to reduce indoor temperatures.
Recommended configuration: Low-E laminated insulated glass / Coated colored-glaze laminated glass
Applicable to: South‑facing and west‑facing areas exposed to intense sunlight, atriums with stifling heat, and sunrooms or courtyards.
Advantages: Blocks infrared radiation, protects against UV rays, keeps indoor spaces cool and comfortable, and prevents furniture from fading.

Option 4: High-Sound-Insulation, Street-Facing Noise-Reduction and Daylighting Skylight
Recommended configuration: 8+8 thickened PVB laminated glass / 10+10 high‑sound‑insulation laminated glass
Applicable to: street‑facing overpasses, garage entrances and exits, and atriums adjacent to roadways.
Advantages: PVB interlayer effectively absorbs noise, delivering significantly better sound insulation than standard insulated glass.

Option 5: Custom-shaped curved/dome‑style skylight
Recommended configuration: thermally bent laminated glass, bent tempered laminated glass, and custom-shaped colored-glaze laminated glass.
Applicable to: spherical domes, arched corridors, and trendy canopy structures
Advantages: Can be formed into any curvature, aesthetically pleasing design, fully transparent, and explosion-proof.

Option 6: High-end, energy-efficient, top-of-the-line skylight system
Recommended configuration: Double-silver Low-E + laminated insulated glass with argon filling
Applicable to: luxury villas, five-star hotels, and high-end clubs.
Advantages: integrated thermal insulation, soundproofing, condensation prevention, explosion resistance, and energy efficiency.

Option 7: Privacy + Sun-Shading Skylight
Recommended configuration: Laminated glass + high-temperature colored glaze / frosted gradient laminated glass
Applicable to: residential atriums, first-floor courtyards, and close-range building-to-building views.
Advantages: Translucent yet opaque, provides shade and sun protection, and balances natural light with privacy.

IV. Common Standard Specifications for Skylight Glass (Industry‑Standard)
Residential small skylights: 6+6, 8+8 double‑steel laminated glass
Medium- and large-span projects: 8+8, 10+10 SGP/PVB laminated glass
Thermal-insulation and energy-saving model: 6+12A+6 Low-E insulated laminated glass
Special-shaped curved glass: thermally bent laminated glass, bent laminated glass
Ultra-white version: Ultra-white laminated glass that eliminates green tinge and offers superior transparency.

V. Key Considerations for Skylights
It is strictly prohibited to use single‑pane tempered glass for ceilings: such installations pose a serious safety risk of spontaneous breakage and falling, and will fail inspection.
The greater the span, the thicker the glass and the more layers of laminated glass are required.
The west-facing project does not use Low-E glass; otherwise, the interior would feel like a steamer in summer.
In cold northern regions, laminated insulated glass is preferred to prevent condensation and frost formation.
Public pedestrian areas must comply with fire safety and security regulations, with priority given to SGP laminated glass.

In addition, the installation and maintenance of glass skylights should not be overlooked. During installation, it is essential to ensure structural stability and excellent sealing to prevent rainwater infiltration and wind‑induced damage. Regular cleaning and inspections are also necessary to promptly remove dirt and standing water from the glass surface, thereby avoiding long‑term buildup that could lead to corrosion or damage. For laminated glass, special attention should be paid to the aging of the interlayer; if cracking or delamination is detected, the glass should be replaced immediately to maintain the skylight’s safety and performance. Throughout the maintenance process, attention to detail is crucial—checking the integrity of sealant strips and ensuring that hardware components are securely fastened. These seemingly minor aspects often have a significant impact on the skylight’s overall quality and service life. Therefore, engaging a professional installation team and scheduling routine maintenance services are key to ensuring the long‑term, reliable operation of glass skylights.
