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 […]

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 […]
