Natural Light 21 Inch Tubular Skylight - Curb Mounted with Transition Box

Why Natural Light Tubular Skylights
Natural Light uses the highest quality materials in the manufacturing process. The entire Tubular Skylight was designed around performance, ease of installation and being able to withstand the weathering effects of any environment. The Tubular Skylight's warranty is the best in the industry, 25 years

Why Tubular Skylights
Tubular Skylights are far more efficient than traditional skylights. Installs in less than two hours without the need of framework, drywall or painting. Because of the design, tubular skylights are very energy efficient; virtually no heat gain or loss is associated with the system. UV absorbing materials in the dome and diffuser ensures that there will be no furniture/carpet discoloration. The mirror-like light pipe provides a tremendous amount of light using a relatively small area, thus enabling installation a possibility in virtually any area. The engineered diffuser spreads the natural light throughout room and enhancing the true colors of the space. Even with all these advantages, Tubular Skylights are far less expensive than conventional skylights!

From the dome to the diffuser, Natural Light tubular skylights are engineered to be easy to install, trouble free and maintenance free.

The Dome is constructed of high impact modified acrylic. Considerably stronger than regular acrylic, it easily withstands wide temperature variations. This material is also UV stabilized, absorbing 99% of UV rays while maintaining optic clarity.

The Roof Jack is .080 aluminum, making it one of the thickest flashings on the market. Its unique forward sloping design eliminates light robbing elbows in most installations and it fits on any flat or pitched roof. The round seamless flange is designed to uniformly expand and contract under changing environmental conditions ensuring years of leak free operation. Easily paintable to blend in with your roof, its low, unobtrusive profile makes it appealing to home owners associations.

The Stress Collar is exclusive to Natural Light tubular skylights. This seamless aluminum collar is factory fastened to the dome and functions to equalize the stress around it. The collar is connected to the roofjack eliminating screws into the dome; avoiding the major cause of leakage.

The Light Pipe is silver coated aluminum with a total reflectivity of 95%. The pipe is easily trimmed with shears during installation.

The Trim Ring is seamless aluminum. Powder coated for durability, it will blend into any decor.

The Diffuser is designed with a precise arc for exact light dispersion without spot lighting or glare. Available in soft white, skybrite (flat only), or prismatic, dome or flat, it snaps into the trim ring for a snug, dust and moisture free seal. The flat diffuser is used where the dome is not prefered. The dome diffuser disperses more light than the flat diffuser.
