The Flashing

The flashing is extremely important, as it is responsible for keeping your roof from leaking. It is exposed to the harsh effects of the environment on a daily basis. Our flashing is constructed of heavy gauge aluminum with no seams, and its round shape minimizes damage to roof shingles and enables it to withstand the stresses of expansion and contraction due to the temperature variations. Our competitors use cheaper grade galvanized materials or plastic with tack welded or rolled seams.  Our unique forward sloping flashing design eliminates the use of light robbing elbows that the competition uses in almost all applications.

The Dome

The dome allows for the sunlight to enter into the light pipe and it too is exposed to the environment. Our dome is constructed of hi-impact UV stabilized acrylic that is twice as thick as our competitors. Unlike most of the competition our low profile appearance allows the skylight to blend into the surrounding roof structure. Most importantly, our dome is mounted in a stress absorbing seamless aluminum collar, which exerts the pressure caused, by expansion and contraction due to temperature effects evenly over the dome. All our competitors attach their dome directly to the flashing that stresses the dome at the contact points. Dissimilar materials react to temperature effects differently, which causes stress cracks to develop.

Light Pipe:

Manufactured by the leading firm in the industry, our light pipe is one of the best performing in the industry. Most of the competition uses cheaper grade light pipe, thinner gauge or less reflective. Our light pipe is assembled on site with three securing methods ensuring a tight, dust free seal.

Trim Ring & Diffuser:

The trim ring and diffuser assembly is the only piece in the entire kit that the homeowner sees on a daily basis, and it's the only item that the homeowner will ever touch. Our trim ring is constructed of seamless aluminum and is powder coated white in color. All of our competition offers plastic, and many have unsightly plastic tabs that hold the ring in place.  Our diffuser easily snaps into place for ease of cleaning, yet it provides a tight seal to ensure heat loss up the light pipe. It's constructed of hi-impact acrylic, which makes it virtually unbreakable. Our diffuser is designed with a small arc that provides even light distribution without spotlight effects. Our competition offers primarily flat diffusers that are brittle and is not able to spread the light out as far.
