Light Transmitting Panels on the roof are the premium Acrylit panel. Ultra-Dek®; and Double-Lok® LTPs are the Sky-Brite® system. The Sky-Brite® system consists of a standard Signature® 300 Snow White Ultra-Dek®/Double-Lok® panel with precision windows cut out. An Acrylit Light Transmitting Panel is then bonded to the standing seam panel using a patented monolithic bonded system. BattenLok®/SuperLok® LTPs are a riveted rail system.

All LTPs are available insulated or non-insulated and with insulation trim.
