New homeowner Evelyn Cagnetti recently contacted NAIMA to share her frustration about her new Energy Star home, which she had built in February of last year. Shortly after moving in, Evelyn noticed that the upstairs was hot, stale, and stuffy during the winter months. Still, she didn’t know why until she checked the second-floor ceiling and found insulation remnants but no insulation.

Architect Terry Smith of TDSA Architecture in Washington state recently contacted NAIMA with a question about how to properly insulate various types of roof trusses – both conventional and scissor type. Terry rightly pointed out that insulation is intended to be most effective when uniformly applied or layered to cover the full extent of the space being insulated. But there are instances, such as narrow areas near the top plate of scissor trusses and sloped ceilings, where that is not possible.

In any roof system with an attic, ventilation is crucial as it allows airflow to come through the attic and exit out the roof vents, which manage hot air and moisture. Installing baffles between the roof’s rafters and trusses will stop the insulation from blocking the airflow through the attic space. Baffles should be installed in the attic wherever there is an intake vent (soffit vent) to ensure proper airflow in the attic. The devil is in the details of the installation, though. Installation guidance can help ensure that the baffles are correctly installed.

While the terms sustainable, energy-efficient, and green building are broadly used to describe construction that centers on Building Performance, there’s no national program that focuses on career development in Building Performance. That’s why North Carolina Building Performance Association (NCBPA) Founder and CEO Ryan Miller is investing heavily in developing the Building Performance workforce in the state.

Getting accurate estimates for insulation installation jobs in new construction homes sounds like a relatively simple undertaking, but for some contractors, getting precise material quantities for jobs can be a challenge. Do you use software to estimate materials, or do you have an estimator review the construction plans? Is it necessary to “walk the house” to get the materials estimates? What’s the best approach? Insulation Institute talked with three building industry professionals about providing accurate estimates for batt and blown in insulation jobs and why it matters to get it right the first time.

Strong new home starts and an uptick in hiring in the construction industry means that new insulation contractors are added to company payrolls every day. With the rise of high-efficiency construction driven by certification programs such as HERS, ENERGY STAR, and LEED, quality installation is more important than ever. To combat common insulation installation issues, we look at three typical missteps made by insulation contractors when installing batts and review ways to avoid them.

We don’t get out to jobsites often. Much of our time here at Insulation Institute is spent developing resources for building industry professionals on how to safely use and properly install fiberglass and mineral wool insulation products, and that keeps us in the office most days. But occasionally, we’re invited to a job site to observe the insulation installation. We relish these opportunities.

Thermal bridging or the escape of heat through low-performing areas in a building envelope presents a huge problem for builders interested in energy-efficient buildings. One of the reasons that modern buildings are now more energy efficient than ever is that newer building energy codes, like the 2015 IECC and ASHRAE 90.1 prescriptively include the use of continuous insulation in most climates to reduce thermal bridging. While there are many different continuous insulation products and applications, mineral wool is gaining in popularity as an effective solution in minimizing thermal bridging.

Thrive Home Builders is one of the most respected production builders in the country with a multitude of awards and accolades to prove it. The Denver-area company is well-known nationwide for its sustainable, energy-efficient construction, with 100 percent of its homes meeting a minimum of Net Zero Energy Ready status. Thrive commands a 10 to 25 percent price premium for its high-performance new construction homes, so one could assume that every product used in its builds would also come at a price premium. Yet, Thrive CEO and Founder Gene Myers told Insulation Institute that cost-effective blown-in fiberglass insulation is a preferred product in his company’s homes.

We at Insulation Institute spend a good deal of our time talking up the benefits of using fiberglass and mineral wool insulation. As much of the content of our blog is geared toward new residential construction, we value connecting with builders who use these products to achieve high-performance new home construction. So, we were thrilled to catch up with Matt Risinger, a Texas home builder and building science enthusiast (and a rock star) who specializes in high-performance, architect-driven home building during the International Builders Show. We’ve heard Matt speak at the International Builders Show in the past and we know his time is a valuable commodity, so we only asked him one question during our brief chat. His answer didn’t disappoint.
