Glass Ridge Light - GRL

Default Value

$0.00

The Skyspan Glass Ridge Light (GRL) is a pitched glass roof system designed to introduce generous, even daylight along the apex of a roof. Suited to long corridors, hallways, atriums, and circulation spaces, the GRL delivers strong daylight penetration while maintaining a refined architectural expression.

Its pitched configuration promotes efficient water shedding and improved performance compared to flat glazing, making it particularly effective for low-slope roof applications. Engineered to Australian Standards and available in single or double glazing configurations, the GRL can be tailored to suit project-specific requirements for thermal performance, glazing specification, and finish.

Manufactured in Australia and supplied as a complete system, the GRL provides a durable, high-performance daylighting solution for both commercial and high-end residential projects.

FAQs

Please read our FAQs page to find out more.

Does a GRL require project-specific engineering?

Often, yes.

Because ridge lights are typically long, continuous, or multi-panel systems, engineering is commonly required to address:

- span and segmentation
- support conditions at the ridge
- wind and live loading
- glazing make-up

Engineering certification is provided on a project-specific basis where required.

Can a GRL be supplied as a single continuous run, or must it be broken into sections?

GRLs are typically segmented into multiple glass panels rather than supplied as a single continuous sheet.

Maximum panel sizes are governed by:

glass manufacturing limits

structural performance

handling and installation considerations

Where longer runs are required, intermediate mullions or segmentation are used to achieve the desired length efficiently and compliantly.

Should I choose single glazing or double glazing?

In most cases, double glazing is strongly recommended, particularly when the skylight is installed over an internal, conditioned space.

Single-glazed glass skylights comply with AS1288:2021 for overhead glazing and are suitable for some applications. However, single glazing is prone to condensation, especially during cooler months or when there is a temperature difference between the internal and external environment.

Condensation can cause water droplets to form on the underside of the glass and drip below, which is often mistaken for a leak even though the skylight is performing correctly.

Double glazing significantly reduces the risk of condensation, improves thermal performance, and enhances occupant comfort. For this reason, Skyspan generally recommends double glazing for habitable spaces, trafficable glass floors, and any skylight installed above internal areas.

Is the Glass Ridge Light (GRL) available as supply only?

No. The Glass Ridge Light (GRL) is supplied as a supply and install solution only.

Due to the size, complexity, and project-specific detailing of ridge light systems — including glazing, framing, flashings, and installation sequencing — Skyspan undertakes installation to ensure performance, compliance, and warranty integrity.

This approach ensures the system is installed exactly as designed and certified.

In most cases, double glazing is strongly recommended, particularly when the skylight is installed over an internal, conditioned space. Single-glazed glass skylights comply with AS1288:2021 for overhead glazing and are suitable for some applications. However, single glazing is prone to condensation, especially during cooler months or when there is a temperature difference between the internal and external environment.

Double glazing significantly reduces the risk of condensation, improves thermal performance, and enhances occupant comfort. For this reason, Skyspan generally recommends double glazing for habitable spaces, trafficable glass floors, and any skylight installed above internal areas.

A GRL is typically specified when:

- Daylight is required along the apex of a roof
- Long corridors, atriums, or circulation spaces need even light distribution
- A pitched glazed solution is preferred over flat roof glazing
- Architectural expression and performance are equally important
