This past Spring, the U.S. Environmental Protection Agency’s ENERGY STAR Program launched a new initiative, the ENERGY STAR Home Upgrade, targeting six high-impact energy efficiency improvements for existing homes to cut energy use and cost. These fixes will also improve home comfort and lead to a cleaner, healthier home.

“We need to think about insulation, or to start thinking about it in the first place,” says a Vox news story this week. As part of a series that addresses our warming world, Vox writer Neel Dhanesha calls insulation the climate solution hiding in our walls. There’s no time like today — Earth Day — to talk about insulation’s important role as a tool for pollution reduction.

Most home builders have a point-person responsible for ensuring that tradespeople are completing their work as specified. For some, that means there’s someone physically walking through homes after the insulation has been installed to ensure that the job is done properly. But do they know where to look? Our 25 checkpoints guide can help.

Blown-in insulation installers know that measuring it in an attic is key to delivering the required thermal performance and receiving a Grade I install. That is typically accomplished by installing attic rulers throughout the space, so there is one for every 300 sq. feet of attic space. Accurate measures are needed to meet code requirements, according to Chris Conway, President of Conway Energy, a building science consulting firm that specializes in single and multi-family construction. No matter how experienced the installer is, you’re going to want to measure every time and check in multiple locations. But there are times when that measurement can be off.

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.

If you’ve been following our blog for some time now, you know that we write regularly about basic building science. In fact, we completed a primer, Building Science 101 with Building Scientist Allison Bailes a few years back. Dr. Bailes, a Georgia resident, recently wrote the state’s Department of Community Affairs to object to a proposal that would allow as little as R-20 spray polyurethane foam (SPF) insulation to be used on the underside of the roof deck in new homes built in the state when R-38 is required. You may ask why R-20 SPF at a blower door rating of 3ACH 50 was proffered as a substitute for R-38 and 5ACH 50. So did Bailes.

Experts predict that 20-30 percent of the U.S. workforce could be working from home multiple days per week by the end of 2021.[1] With this shift to remote work, a dedicated home office becomes essential, and optimizing that space for functionality and comfort is a top priority.

Fiberglass batts are commonly used to insulate flat ceilings and attic areas in both new and existing buildings. They offer performance, cost-effectiveness, and relative ease of installation, but that doesn’t mean they’re always installed properly. The performance of any insulation product is dependent not only on selecting the proper product but also on installing it correctly. So, how does one install batts in flat ceilings to maximize thermal performance?

NAIMA has released a new report that documents the acoustical performance of residential wall cavity insulation products. The report is based on research conducted by Intertek Labs that tested seven wall assemblies with variations in cavity insulation products, including fiberglass, mineral wool, open cell spray foam, closed cell spray foam, and flash and batt applications with spray foam and fiberglass insulation.
