SolaMaster® Series

Solatube® 21-C & 21-O Daylighting Systems

The Brightest Idea in Daylighting

Expansive spaces require extraordinary amounts of natural light so we designed the SolaMaster Series. These Daylighting Systems feature our largest aperture tubing and patented LightTracker™ Reflector for effective daylight harvesting. With our Spectralight® Infinity tubing, these systems make it possible to bring natural light deep into buildings where natural light has rarely been an option.

The Solatube 21-C is great for Retail, Schools, Offices, Medical Rooms, Stairwells, Lobbies and Family Rooms. Use the Solatube 21-O for Warehouses, Manufacturing Plants, Gyms, Lofts, and Unique Architectural Effects.

The innovative design of our OptiView Diffuser delivers the cleanest, purest natural daylight imaginable. A matrix of individual Fresnel lenses offers a unique view of the sky above and also provides unrivaled and highly engineered diffusion.

The Frosted Diffuser offers a unique appearance on the ceiling with crystalline highlights as the sun moves. The lens is soft with even amounts of light and has a glimpse of ever changing sparkles for highly-effective diffusion.

Flashings

21-C

A full selection of durable flashings ensures leak-proof, hassle-free installations on virtually any roof type and pitch. The Solatube® self mounted flashings eliminate the need for expensive curbs and can be integrated into the roofing system for a worry-free installation

The 4 in/100 mm high flashing is recommended for most residential applications because of its low profile.
The 8 in/200 mm and 11 in/280 mm high flashings are recommended for use on flat commerical roof applications to meet commerical curb height requirements

Daylight Dimmer™
Because you don’t need 100% of the light 100% of the time, the innovative Solatube Daylight Dimmer easily controls the amount of daylight entering a room with the convenience of a switch. Our patented* variable butterfly baffle controls the light output. Accepts power supplies ranging from 90 to 277 volts AC.

Daylight Dimmer Switch Works with our Daylight Dimmer switch (sold separately)

* Patent #7,082,726

Secondary Diffuser
To eliminate unwanted glare or to reduce light output, an optional secondary diffuser can be inserted into the Solatube® Daylighting System dome for natural lighting preference.

Spectralight® Infinity Extension Tubes
Extension tubes can be added in increments of 24 in/600 mm for long runs without sacrificing performance. Spectralight Spectralight Infinity has the highest reflectivity in the world for the brightest, purest light. Create tube runs of up to 50ft/15m.

Flashing Turret Extensions
Use to raise the height of the Solatube dome on a roof to avoid snow, water, or shading from roof obstructions. Order additional Spectralight® Infinity tubing to accomodate turret height. Available in 12 in/300 mm, 24 in/600 mm, 36 in/900 mm and 48 in/1200 mm sizes.

Transition Box
The Solatube 21-C features a patented transition box that seamlessly converts the round tubing to a square diffuser. The transition box easily fits into standard commercial ceiling grids.

Flashing Insulator
This insulating material helps to reduce flashing condensation in cold climates when the flashing is exposed to a humid interior space. The insulator is affixed to the flashing base and the top tube slips through the opening, which provides a seal between the interior and metal flashing.

Open Ceiling Trim Ring
For use with the Solatube 21-O, the trim ring provides a finished appearance to the installation.

Daylight Dimmer™ Switch
Daylight Dimmer Switch Kit includes DPDT switch, wall plate and 15 ft/4.5 m of cable. Multiple Daylight Dimmers can be controlled by one switch.

Security Bar
This stainless steel bar inserts into the flashing turret across the diameter of the opening. The bar is fastened using rivets and prohibits entry through the dome.

Dome Security Kit
The kit consists of six rivets with protective nylon spacers, which replace dome screws. The dome security kit reduces the possibility of the dome being removed.

Wire Suspension Kit
Use the wire suspension kit when additional bracing to the structure is required.
