This model consists of a durable, weather resistant, extruded aluminum retaining frame and an extruded aluminum heliarc welded base frame. This aluminum base frame is not thermally broken and is recommended for year round moderate climates or for single glazing applications, such as walkways, balconies, carports etc. This model is typically used for larger skylights that require additional strength and rigidity.

The entire skylight lifts off the curb and is sealed to the curb with a high density foam gasket when closed.
