Glass Roof & Skylights Introduction

Various buildings that need daylight use glass roofs and skylights. For example, hotels, stations, airport terminals, department stores, exhibition halls, gymnasiums, museums, hospitals, and residential buildings. Large patio covered with various forms and colors of glass, constituting an indoor glass space unaffected by the climate. So people can not only enjoy natural light exposure but also look at the clear sky.

The glass roof atrium in the building is a central space for natural lighting. In addition, this space plays a role in organizing and coordinating the surrounding buildings. Buildings with glass roofs and skylights are generally more compact in layout, more effective in managing smooth indoor spatial communication. In addition, it has good orientation and creates a unique spatial sequence.


Choice of glass

Roof Glass Strength

It refers to the glass resistance to wind or snow load capacity. We should calculate the calculation of constant load, wind load, and snow load.

Seismic performance

The damage of glass roofs and skylights in the earthquake is in a variety of situations. First, we should consider the glass extrusion deformation resistance and the support system whose seismic performance.


Air permeability performance indicates the sealing ability of the roof in all parts of the closed state. Therefore, the sealed roof has strict requirements for airtightness.


It refers to the ability of the glass roof to prevent rainwater from leaking inside under the simultaneous action of wind and rain or snowmelt. Water on the top is related to the storm’s wind speed, rainfall, and the amount of water after the snow melts. Therefore, the condensation on the inside of the roof is a very traumatic problem. In addition, dew water dripping down from the ceiling is a very annoying thing to people. Therefore, the design slope should consider preventing dew from leaking down.

Insulation performance

Glass light roof heat transfer coefficient or heat transfer impedance and the different glass used and different. For example, heat-reflective coated glass, insulating glass, heat-reflective insulating glass are significantly different. In addition, we should also consider sound insulation performance, fire resistance, hail (impact resistance) performance, lightning protection design, etc.

The glass roof and skylight is a specialized, complex technology in the building. Therefore, we should consider both design structure and glass materials. Please feel free to contact the VSOM team for the glass choices.
