Standard Skylights (unit skylights)
Certifications
CrystaLite skylights are NAMI certified and NFRC rated for thermal performance; U-factor, SHGC, and VT (visible light transmittance). Skylights are NAMI certified to the NAFS Standard for air infiltration, water penetration, & structural loading; commonly referred to as ‘AAMA Testing.’
[AAMA/WDMA/CSA101/I.S.2/A440]
Design Loads
Design loads (downward pressure) established by certification to the NAFS Standard include a 200% safety factor. All standard glass glazed skylights are certified to 85 psf design loads. Plastic glazing certification various depending on size and configuration.
Snow / High Loads
CrystaLite’s 5842, 3962, 5830, and ES frames have been certified with high load specific glazing configurations to achieve a high design load ratings of 310 – 330 psf to comply with local code requirement for snow loading concerns. Available upon request.
Skylight Frames
We offer several options in standard skylight frames; including a standard aluminum frame, an aluminum thermal break frame; and our highly insulating PVC/Aluminum frame series. CrystaLite’s primary standard skylight is our 5842 frame, capable of encompassing both insulated glass units and acrylic dome glazing for fl at roofs. The 5843 frame is our production line model of our PVC frames, limited to our most common sizes and insulated glass units.
Our 5830 frame is our operable PVC skylight and is available with manual and electric opening hardware.
Fall Protection Safety Grids
CrystaLite skylights are designed to withstand environmental forces; however not intended nor designed to withstand human impact and should never be walked upon under any circumstances.
For protection of falling through a skylight opening in the event of a fall, we offer two variations of Safety Grids to provide fall protection.

The upper assembly of the ES Skylight now features our 5842 PVC frame and an insulated glass unit. This upgrade is to ensure condensation control and exceptional thermal properties while maintaining a clear view, high visible light, and great STC. High Load glazing available.
5842 PVC/Aluminum Frame
This is our most common curb mount frame featuring a PVC interior frame and a bronze or clear anodized aluminum cap. The PVC interior provides an excellent thermal break. Custom sizes are available. All corners are welded – interior and exterior. High Load glazing available.
5843 PVC/Aluminum Frame
This is our production line frame, offered in models 2626, 2638, 2650, and 2674 sizes only; and limited to insulated glass glazing only.
3962 Aluminum Frame
Standard aluminum frame, also available as an opener. High Load glazing available.
3921 Thermal Break Frame
Thermal break frame features a resin core within the interior aluminum extrusion.
Dome Glazing
Glass skylights require at least a 2/12 pitched roof for installation to allow for water runoff. For flat and low pitched roofs, acrylic dome glazing is available.
Domes are available in single, double, and triple layers to meet your energy design needs. Available in clear for maximum light; bronze for reduced heat transmittance; and translucence white for optimal light diffusion.
