Easier, Faster and More Accurate Wall Designs

Wall designs are one of the most time consuming projects for an architect.  As you design buildings that are energy-efficient and compliant with code changes, the wall details become more detail-oriented and evermore critical to the performance of the building. Cosella-Dörken, in collaboration with Roxul, has generated BIM files for wall sections, including air and water-resistive barrier details. […]

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 […]

LEED Certification and Air Infiltration

Leadership in Energy and Environmental Design (LEED) certification is an independent verification method that recognizes green building performance. LEED certified buildings are generally assumed to be more energy-efficient than standard structures. LEED® certification can enhance a building’s value, generate higher commercial lease rates and reduce utility costs. By 2018, it is estimated that LEED-certified buildings will contribute almost $30 […]

Common Problems that Reduce the Effectiveness of Your House Wrap

High-quality house wrap is most often made of spun, high-density polyethylene fibers. It is a vapor-permeable material designed to simultaneously block the passage of liquid. Properly installed, it’s a WRB with the ability to resist moisture while allowing humidity to escape from exterior wall cavities, which is of particular importance in humid climates. However, unforeseen […]

Air and Moisture Barriers Important to Net Zero Homes

Over the past decade, net zero homes have grown in popularity. They are also more viable as solar panels have dramatically decreased in cost while increasing in efficiency, and energy storage systems have become far more cost-effective. Now, the National Association of Home Builders (NAHB) cites a report from the Net Zero Energy Coalition (NZEC) stating that 6,200 housing units […]

A Solution for the Construction Labor Shortage

For years now, the labor shortage in construction has continued. While every firm may have some understanding of the current lack of skilled labor, the problem is likely much deeper than it is often thought to be. To be precise: the Associated General Contractors of America (AGC of America) issued a press release claiming that 83% of contractors report having difficulty finding […]
