Rectangular unit skylights are available in a wide range of standard sizes and can also be custom fabricated to your project dimensions. Circular and octagonal units are offered in standard sizes. Contact us with your curb dimensions or required daylight opening and we'll confirm available options.

Unit skylights are available in three mounting types: curb-mounted (installs onto a site-built or prefab curb), insulated curb (thermally broken curb is part of the unit), and self-flashing (for low-slope or pitched roofs without a separate curb). The right choice depends on your roof type, slope, and thermal performance requirements.

In general, acrylic glazing should be cleaned with mild soap and water - avoid abrasive cleaners or solvents, which can craze or cloud the surface. Glass glazing can be cleaned with standard glass cleaners. Frames should be rinsed periodically and inspected for sealant integrity annually.

A Skyline Sky-Lite is designed to perform trouble-free. Every design incorporates a weep system to channel any moisture from within the frame to the exterior and away from the skylight. The design is not dependent on any exterior wet seals which could fail over time. If a skylight is mounted properly and sealed to its curb per the manufacturer's instructions, it is very unlikely that it will ever leak.

Three common errors exist which most often cause skylights to be blamed for leakage. The first and most common is improper flashing around the skylight curb. To determine if a leak is the result of poor flashing, allow water to run down the roof from a point above the location of the skylight - do not run water directly on the skylight itself. You will likely see evidence of the leak appearing at this point without ever wetting the skylight.

Secondly, a person unfamiliar with the design may apply caulking to the edges and integral weep holes - these are designed to allow condensation and moisture to weep to the outside of the building, and sealing them will cause moisture to overflow to the interior.

Thirdly, a low-grade skylight design without a thermally broken frame in the wrong environment may condensate, which can also be interpreted as a leak. It is important to select the proper skylight properties for your application.

Skyline Sky-Lites manufactures standard units with approximately 1/2" tolerance on each side of the perimeter to allow for roofing materials and construction tolerances. Your curb may be slightly larger or smaller in either direction and still fit. However, the responsibility for providing accurate dimensions for fabrication is up to the customer.

Self-flashing - A self-flashing aluminum skylight is generally used on a flat roof application where the roofing material is adhered to the integral skylight curb, forming a watertight seal. The roofing material is to be sealed per manufacturer guidance, preventing water from seeping under the self-flashing flange.

Curb mount - A curb will be required on all roof types other than the typical low-profile composition or asphalt roof. The roofer installing specialized roofs - such as standing seam metal, tile, or shake - will be best able to provide an adequate curb and flashing system for the skylight.

The acrylic glazing found in Skyline Sky-Lites inherently blocks about 99% of ultraviolet light, generally providing adequate protection for the room below. However, for total protection it is recommended that direct light be replaced with diffused light, thereby eliminating the "light trail" or "hot spots" associated with direct sunlight.

Acrylic will expand and contract throughout the course of a day as the outside temperature changes. This can cause a slight crackling sound. In some applications, this slight noise may be amplified greatly as a result of the skylight well in the ceiling.

No, we do not offer flashing kits.

Both have distinct advantages depending on the application. The tempered exterior glass used in Skyline's flat glass skylights retains a higher impact resistance than acrylic, which may be useful in locations prone to hail. A minimum recommended roof pitch of 3 in 12 is required for flat glass skylights - lower pitches may allow water to pool on the glass surface, leading to dirt accumulation and eventual staining.

Domed skylights tend to remain cleaner as rainwater sheds much more quickly due to the dome shape. Glass skylights also eliminate the potential for the slight crackling noise that can occur with acrylic skylights as a result of thermal expansion.
