Skylight Frames

Our all-aluminum roof lights are constructed of extruded aluminum frames, thermally broken throughout. Rafter sizes can be varied to meet any design load requirement. Each rafter has an integrated gutter to channel any water ingress to the eave. Eave glass is retained by an extruded aluminum compression clip with concealed gaskets.

All internal rafters feature an optional ogee profile aluminum extrusion lending perspective to the interior framing. A molded nosing at the interior side of the sill is standard on skylights with side frames. Flat rafters are optional.

Wood trim interior is optional.

Roof Pitch

Standard roof pitch is 25 degrees, but can be customized.

Curb Dimensions and Flashing

All skylights include shop drawings for Purchaser pre-approval. Curb is built and flashed by Purchaser.

A minimum curb height of 6 – 8 inches above highest adjacent roof surface in snow zones or local code requirement is recommended.

Frame details are available for download in the right-hand column.

Installation and Warranties

Structural Considerations

All skylights are engineered to the snow and wind loads required for the installation location. Local snow and wind load factors are requested in the contract. We can design to any snow or wind load or coastal hurricane code requirement. Design test pressure ratings are available for certain sizes for hurricane zones, with more being tested regularly. The owner is responsible for building code compliance and proper structural support for the skylight. Dead loads are provided at order.


10 year structural and 20 year insulated glass seal warranty and one year installation workmanship warranty.


We provide installation on the Owner’s prepared curb. Shop drawings for Owner’s pre-approval provide opening details and flashing requirements. Most skylights can be erected in 2 to 4 days or less, longer for the largest sizes or sites with access restrictions.
