While heating exterior penetrations wastes energy and increases carbon emissions and operating costs, chilling interior structures reduces comfort and allows condensation and mold to form on adjacent surfaces. Therefore, one must look for an alternative solution.
The need for energy efficient buildings is the largest driving factor behind product innovation and building science advancements in air barrier materials. However, other equally important aspects of modern construction are sometimes overlooked by building professionals.
When one comes across the R 13 + 7.5 ci wall insulation requirement in the International Energy Conservation Code (IECC) commercial provisions, it can be tempting to just add the two R-values and install R-20.5 rated insulation in the cavity with the assumption being that the same performance can be achieved with fewer steps.
When the National Football League (NFL) announced its 52nd championship game would take place in Minneapolis, Minnesota, professionals in hospitality, commercial real estate, and construction industries in the Twin Cities scrambled to capitalize on the future economic infusion from the big game, slated for February 4.
Many conflate R-value with good thermal performance or insulating value. The belief is the higher the R-value, the better the thermal performance. However, as a blanket statement, this could not be any further from the truth.
