Silver coating

Cardinal Glass Industries launched Quad LoE-452, a true four-layer silver coating with solar control and the lowest emissivity within the Cardinal Glass family of low-E coatings, say officials. Quad 452 comes standard with Neat+ glass, creating a combination of superior performance and naturally cleaner glass. Quad 452 has a solar heat gain coefficient of 0.22, a visible transmittance of 52 percent, and a 2.30 light-to-solar-gain ratio.
