MC5 is the only true unitized rainscreen window wall system on the market today. Thanks to a series of five chambers within the system, MC5 completely eliminates external moisture penetration. Plus, the introduction of the I-Strut thermal break 85% wider than the standard PVC break significantly reduces heat and cold transfer. The U-Value and condensation index are both improved by 50% over traditional window wall systems. In fact, tests show that with the introduction of high-performance Low-E glazing and a warm-edge spacer, the window can achieve a U-Value of 0.29 BTU/hr-sf F.
