As building codes and energy codes continue to advance, especially as they are beginning to align with the latest versions of ASHRAE 90.1, the requirements for higher performing exterior envelopes is becoming the norm on many buildings across the country.
With more stringent U-values, and much lower Solar Heat Gain Coefficients (SHGC) for fenestration systems, the cladding industry is quickly reacting by providing more high performance systems for the typical building stock. In addition, strong research into the effectiveness of air barriers, and the demonstrated cost savings when they are properly designed and installed, continues to highlight the importance of the building envelope and its roll in energy performance.
