From Alaska to Cleveland, skylights can present problems anywhere. Following is a sampling of the newest skylights on the market and solutions to various skylight challenges.
Architectural Product Sales Company, Inc. of Terrell, TX, faced a major challenge on its recent project at the Greater Cleveland Transit Authoritys North Coast and Settlers Landing Stations. The company was challenged to interface vertical curtainwall and sloping skylights in a self-supporting design condition.
To meet these needs, the company used Vistawall Architectural Products of Terrell, TX, and Naturalite Skylight Systems of Dallas, TX. The team used a self-supported ridge skylight at the connecting bridge, with moment connections at the sill, knee and ridge to solve the problem. The Naturalite products used were barrel vaults and 18,000 square feet of BMS 3000 ridges, while the Vistawall products used were CW-250 curtainwall, FG-2000 flush glaze and standard bone white interior finish.
Wasco Products of Sanford, MN, is offering the E-Class Skywindow series, its flagship residential skylights, in custom sizes and standard dimensions. According to the company, custom sizes permit installation over existing roof openings and light wells.
The skywindows are one-piece, fully preassembled units that install without any step flashing, mastic or sealants, according to the company. The E-Class contains a co-extruded PVC flange that surrounds the PVC curb on all sides to flash the skylight onto the roof deck
Custom sizes are available for rough openings up to 16 feet, in widths ranging from 16 inches for fixed models and lengths from 18 inches to six feet.
According to the company, the E-Class controls water with channels on the flange that divert it, a PVC gutter that catches moisture from the glazing and allows it to evaporate and by sitting squarely on the roof deck and surrounding the opening.
Naturalite Skylight Systems offers the EZ Pyramid and EZ Ridge skylights. According to the company, the skylights come with pre-fabricated parts, marked to coordinate with drawings, and may be installed in 15 to 20 percent less time than competitive systems.
The skylight systems are available in a variety of sizes, pitches and finishes, and accept a variety of glazing infill thicknesses. In addition, the company says lead times are minimized by custom fabrication software and stocking inventories.
Arctic Glazing contractors recently installed a Skywall Translucent Systems exterior for the Alaska Native Medical Center in Anchorage.
Skywall produced a canopy that spanned over eight feet, with a custom bull-nose perimeter created in-house, and trapezoidal- shaped panels that would support a 40 psf snowload. The canopy also contained a 2-3/4-inch-thick insulating translucent sandwich panel with a crystal fiberglass exterior, a 0.40 U-Value and light transmission of 60 percent. The canopy was finished with white Kynar®.
Gammans Architectural Products, Inc. of Newman, GA, offers a solution for glazing contractors who are plagued with problems resulting from a lack of time and manpower. To solve these problems, the company has introduced several new innovations in its skylight program. According to the company, these innovations are designed to make it easier for glaziers to order and install custom pre-engineered and fully fabricated pyramid and ridge standard kits up to 30 feet wide. The company says the skylights are designed to slide and interlock quickly. The skylight frames are available in standard or custom Kynar® and anodized finishes.
