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 […]

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 codes […]

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 […]

Energy Efficiency Starts with Airtightness

Building for sustainability, safety, and comfort requires the combined effort of engineers, architects, sub-contractors, and builders who understand how to design and specify an energy-efficient building envelope. This begins with the design concept and carries through to pricing, design review, construction, and building envelope commissioning. The preferred method for significant reduction in energy use and […]

How Airtightness Testing Improves Building Performance

Air Tightness and Building Performance High performing buildings are durable, comfortable, healthy and low-energy users.  An essential component of the high performance building is minimized air leakage.  Commercial air tightness testing is a quality control tool providing data for the mechanical engineer’s load and energy calculations so he/she can design the appropriate mechanical system. As […]

Airtightness 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, airtightness is gauged by measuring the building envelope’s effectiveness. But what exactly does air-tightness mean? Its technical meaning, unlike some terms […]

Creative Building Design Requires High Performance Water-Resistive Barrier Solutions

The Science Pyramid at Denver Botanic Gardens invites visitors to explore the relationship between people and plants, and to examine the role of biomimicry in our lives – the way the features of nature inspire ideas and actions in people. It’s not surprising then that the building has a great relationship with its surroundings. Rising to a comfortable height among the […]

Air and Moisture Control in Buildings

Air and moisture control in buildings is a fundamental function for any commercial project involving conditioned space. Unfortunately moisture problems are common in many buildings and people often consider them inevitable. Moisture accumulation is the scourge of buildings throughout the United States, from tropical Hawaii to arctic Alaska and from the hot, humid Gulf Coast to the hot, dry Sonoran Desert. Between […]

Air Infiltration vs Insulation: Continuous Air Barrier System Deserves Attention

In a recent article for Green Builder Media, Chris Norris suggests that the energy-saving potential of continuous air barriers is often underrated. For some time, state energy codes focus more on conductive heat transfer through exterior walls than on air leakage. Now, building codes increasingly set air leakage standards as well. Air Infiltration vs Insulation […]

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 Purpose and Characteristics of a High Performance Air Barrier

Building tenants are understandably concerned over the quality of the interior space that they occupy. The comfort and integrity of the building will be enhanced if a high performance air barrier is incorporated in the building envelope. A good air barrier provides a separation between the conditioned interior space of the building and the uncontrolled […]

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 […]

Net Zero Energy Building Envelope Design

Net zero energy building envelope design should be of primary importance to every commercial contractor, asserts the Center for Climate and Energy Solutions (CCES). “Space heating, cooling and ventilation,” says the CCES, use up the most energy in commercial sector, and comprise “34% of the energy used onsite.” Net zero energy, the term used in […]
