Homebuyers are increasingly concerned about the safety of the products that are used in their homes. When it comes to insulation, there’s a lot of information out there, but it can be hard to separate fact from fiction. Insulation Institute has just released a new guide, Fiberglass Insulation A Guide to Better Indoor Air Quality, which details the significant benefits of using fiberglass insulation, whether you’re a builder, installer, or homeowner.

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.

A newly released study of the insulation industry’s economic contributions to the U.S. economy in 2019 details more than 564,000 jobs generated and $36 billion in payrolls that supported families and communities around the country. Those jobs in the manufacturing, distribution, and installation of insulation will be a critical component of the nation’s continued economic recovery in the wake of the COVID-19 pandemic, according to the study’s sponsor, the American Chemistry Council (ACC).

The Federal Emergency Management Agency (FEMA) has released a long-awaited study detailing archaic building codes’ impact on communities. The report concludes that 65 percent of counties and municipalities in the United States have not adopted modern building codes. These communities incur an additional $1.6 billion a year in property damage due to flooding, strong winds, and earthquakes – costs that could be averted altogether if building codes were up-to-date.

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.

In last week’s blog post, we reported that architects are seeing changes in home design due to the COVID-19 pandemic. According to the American Institute of Architects (AIA) Home Design Trends Survey, there is a greater interest in indoor air quality (IAQ) among custom builders and renovators. That finding piqued our interest in whether semi-custom and production builders are also increasing their focus on indoor air quality and what that could mean for building costs. In this week’s blog post, we talk to Matthew Cooper, Senior Vice President, PEG, LLC, about how the broader homebuilding community is responding to the focus on indoor air quality and why increased emphasis on IAQ doesn’t necessarily mean increased costs.

A plethora of new reports indicate that coronavirus is shaping home design trends in the U.S. and globally. Among them, the American Institute of Architects Home Design Trends Survey shows that more outdoor features and flexible spaces are highly desirable. The survey also shows products that improve indoor air quality, thermal moisture control, and energy-efficient homes are growing in popularity.
