Aluminum Framing

Mac Skylights are fabricated from 6063-T5 extruded aluminum alloy. Some structural components utilize the stronger 6063-T54 alloy. In addition to this, some frame components incorporate a thermal break. This thermal break consists of a core of structural, insulative material, which thermally divides the warm inner portion of the aluminum frame, and the cold outer portion, thereby increasing thermal efficiency.

Corner joints of unit skylights have a continuous weld to provide protection against leakage. Unless otherwise specified, all aluminum framing is supplied in mill finish. All skylight models are available with optional pre-finished brown or white enamel paint finish on all exterior exposed aluminum. Anodized or custom color finishes are available on special order.

Larger skylight assemblies are custom fabricated to suit specific jobsite conditions. Framing components are welded and/or mechanically connected. Unless otherwise specified all aluminum framing is supplied in mill finish. Custom painted framing components are also available.
