Industry codes are tightening the building envelope and increasing the required R-value of walls. This is a good thing for energy savings and thermal comfort. Yet, one change to a building’s system sets forth a series of other changes. The tight-envelope construction techniques to which architects and builders are now required to adhere have led to a steep reduction in air movement through walls.

Continuing Education on Continuous Insulation

continuous - Tom's article 2015 - 5th-&-Alton Shopping-Center

Continuous insulation (ci) has been a component of exterior wall assemblies for more than 40 years in North America and even longer in Europe. It has always been the smart way to design wall assemblies from the standpoint of energy conservation and water management. By minimizing energy loss caused by thermal bridging and the risk of condensation caused by water vapor diffusion, exterior ci can improve building durability and benefit the environment.

Waterproofing failures are more easily overlooked than roofing problems, so design professionals tend to hear less about them. When compared with a reroofing project, however, a below-grade or interior rehabilitation can be far more disruptive and expensive. Whereas a roof leak can generally be identified with simple test probes, waterproofing breaches can be challenging to diagnose.
