SkyVault
Big Tubes for Big Spaces
The SkyVault Series, Model M74DS-O high-output Tubular Daylighting Device delivers massive amounts of daylight to large volume spaces with high, open ceilings while reducing on center spacing for fewer roof penetrations.
The SkyVault Series gives building designers a Solatube daylighting solution that delivers maximum output while minimizing the impact on the building envelope and significantly reducing installation costs.
