Neat Glass

You may request Neat® glass, which harnesses the sun’s UV rays to loosen dirt so water can rinse it away, leaving windows virtually spotless. A special sputter-coating process makes the exterior glass surface ultra smooth, so the water "sheets off" more readily than it would on uncoated glass, allowing you to spend less time cleaning.

Preserve Protective Film

Preserve is an optional, protective film that protects the glass from scratches during transit and construction, as well as reducing the time involved in job site clean-up.
