Vault Skylights That Maximise Natural Daylight Indoors
Vault skylights are ideal for larger spaces, creating dramatic rooflines, maximising natural daylight, and making a striking architectural statement.
Rainbow Skylight International designs, manufactures, and installs custom vault skylights throughout South Africa. Our bespoke solutions are engineered to flood expansive interiors with natural light while enhancing the architectural character and visual appeal of the space.

Rainbow Flush Glazed Glass Skylights

Flat skylights are glazed rooflight systems designed to bring natural light into the space below through a streamlined roof opening. They are often selected for projects that need overhead daylight with a more subtle architectural expression.
Rather than becoming the main feature of the roof, flat skylights support the overall design of the building. This makes them especially well suited to modern homes, commercial interiors, and architectural spaces where simplicity and finish matter.
Compared with more raised or feature-led skylight types, flat skylights are typically chosen for their balanced appearance, design flexibility, and ability to deliver daylight in a clean, contemporary way.
Specifying Vault Skylights
Vault skylights are curved, arched, or elongated rooflight systems designed to introduce natural light across broader spans while forming a strong, continuous architectural feature on the roof.
They perform particularly well in long, linear spaces such as corridors, walkways, and gallery-style interiors, where they draw light through the full length of the space, creating a unified sense of volume and enhancing overall spatial flow.
They are also highly effective in atriums and double-volume spaces, where the curved or elongated form becomes a defining architectural element while flooding the interior with daylight from above.
In covered outdoor areas such as patios, verandas, and entertainment spaces, vault skylights provide shelter while maintaining a bright, open-air feel.
They are well suited to premium residential homes, covered outdoor areas, atriums, feature interiors, and bespoke commercial environments where both daylight performance and architectural impact are essential.

Choose the Right Configuration for Your Roof
Whether you’re designing a feature space, atrium, or large-span roof, the right vault skylight depends on scale, structure, and architectural intent.
Get in touch with Rainbow Skylights to discuss your project and find the ideal configuration for your space.
Installations for Long- term performance
Because these skylights are often more bespoke and structurally demanding, installation must carefully resolve support, waterproofing, flashing, roof integration, and the final architectural finish. Good design coordination is essential if the skylight is going to perform well and look fully at home within the roof.


Frequently Asked Questions
Vault skylights are often the right fit where the project calls for a longer-span rooflight, a more sculptural roof form, and a stronger architectural daylighting effect.
In many cases, yes. Vault skylights are often tailored to the opening, structure, and design goals of the project.
It helps to know the size of the opening, the roof type, the intended visual effect, and whether the project requires a highly bespoke solution or a more standardised starting point.
