Safety-Rated and Fire-Rated Wired Glass Solution

SuperLite I-W is safety rated and meets the recent code change! Click here for more information.

SuperLite I-W is the first patented wired glass product to meet the highest federal impact safety standard, Consumer Product Safety Commision Cat. II, which requires withstanding 400 ft. lbs. of impact, and is perfect for use in door and sidelite applications where impact safety is required or a concern.
