UL 90 LIGHT TRANSMITTING PANEL INSTALLATION

The light transmitting panel is designed to be installed in a manner similar to a panel application, utilizing the same panel lap (3’) and fastener layout.

NOTE

The standard light transmitting panel is 10'- 3" long, designed for applications with purlin spacing no greater than 5'- 0" 3/16" (1:12 slope). Maximum width of purlin flange to be 3 1/2".

UL 90 light transmitting panels are shipped with a stiffener plate and ten self-drilling #1 E fasteners for each light transmitting panel.

The stiffener plate is to be field installed on the bottom side of the light transmitting panel over the mid-purlin.

The light transmitting panel rivets that obstruct the stiffener plate must be drilled out and replaced with Fastener #1 E in five places on each side. THIS STIFFENER PLATE MUST BE EXACTLY CENTERED OVER THE MID-PURLIN SO THAT THE THERMAL MOVEMENT OF THE SYSTEM IS NOT RESTRAINED BY THE PURLIN.

NOTE:

THE WASHERS REQUIRED AT THE DOWNSLOPE END OF THE LIGHT TRANSMITFING PANEL ARE #14 x 1 1/8" BONDED

IMPORTANT NOTE Floating Clip must be used on UL 90 rated light transmitting panels.
