The Pros Know: Dr. Straube chooses an airtight, vapor permeable barrier for his coach house

If there’s anything that will convince people of a building product’s worthiness, it’s when the pros use it in their own homes – where they’re free to make unilateral decisions, based on their own expertise and preferences. So you can imagine our excitement when Dr. John Straube chose our air- and water-resistive barrier for his new […]

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 […]

Air Tightness and Window Design: Is the Solar Design Obsolete?

Engineers are now coming to the conclusion that air-tightness is more important than window design in the conception of an energy-saving house.   According to the website for the Air Barrier Association of America, air tightness is gauged by measuring the building envelope’s effectiveness. But what exactly does air-tightness mean? Its technical meaning, unlike some […]
