Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing.

Buildings are a combination of design and construction. On paper, it may all seem to flow and make sense, but a small change in the former can have major impacts on the latter. Alterations that happen during the construction phase can end up causing significant design problems.

Insulation manufacturers have devised numerous ways to improve the thermal performance of their products. Adding carbon or alumina particles to expanded polystyrene (EPS) increases infrared reflectance, and hence boosts R-value. For buildings that need heat stopped during the day and released at night, there are phase-change materials.

The fluid-applied air barrier (FAAB) concept was originally a Canadian-developed technology from more than 40 years ago. Back in the early 1970s, the genesis was an adhesive combining air- and vapor-retarding characteristics—eventually, this material would find its way into building codes.

The importance of understanding the flashing design principles and installation requirements between the masonry wall assembly and the roof flashing system cannot be understated. All too often, the exterior masonry walls of a building structure are thought of as being watertight and require little or no maintenance.
