Entice more customers

ThermaGuard glass creates an optimal shopping experience, making refrigerated products look good enough to eat. Enhanced light transmission, low reflectance and scratch resistance curb distractions so customers can concentrate on the cool merchandise inside. ThermaGuard keeps the cold where it should be—on the inside—not the exterior, where it can form condensation that clouds the view and gives shoppers a chill.
