Why You Should Use Air and Moisture Barrier with Foam Sheathing

  There are a number of reasons why you need an air and moisture barrier over foam sheathing. Airtight exterior wall systems are critical to maximizing energy efficiency and gaining LEED points. However, certain characteristics of foam sheathing conspire to compromise airtight construction. The solution? Use foam sheathing together with a high-performing, moisture-resistive air barrier. As building […]

Energy Efficiency in Modern Buildings

As modern building materials advance, energy efficiency is inescapable. Near-zero energy buildings are becoming increasingly popular in Europe. However, this will not have a great effect on energy consumption as a whole until energy efficient building materials and practices are widespread. Iowa State University Professor Yu Wang states that energy efficiency is relatively inexpensive when […]

The Importance of Designing Adaptive and Dynamic Building Envelopes

Professionals in the construction industry have seen the buzzwords “resilience” and “adaptation” in their work, especially when it comes to the importance of building envelopes. While some might see the words skeptically as a trend, Irene C. Pau at Consulting-Specifying Engineer goes to show that implementing adaptive and dynamic building envelope goes a long way […]

Energy Efficiency Adds Value to Your Property

  Insulation Requires a High Performance Air and Moisture Barrier to be Effective In the past, buildings had drafts, allowing air and moisture vapor to flow relatively freely through the exterior walls, keeping the wall cavity moisture-free. Increasing levels of insulation kept buildings more comfortable, but insulation can create a dew point inside the wall […]

Proper Air and Moisture Control in Homes, According to the US Department of Energy

Air and moisture control in homes, says the US Department of Energy, begins with a discussion of what used to be called “vapor barriers,” but are now referred to as “vapor diffusion retarders.” Vapor diffusion retarders can aid in controlling moisture within “basements, ceilings, crawlspaces, floors, slab-on-grade foundations and walls,” and accomplish this by cutting […]
