Quick Update

Last week we hit a number of big milestones. The house has new ductwork, is completely insulated, and the crawlspace encapsulation is almost finished. Mitch Sosebee with Sosebee Services replaced all of the ductwork on the heating and cooling system. The old system was poorly installed and incredibly filthy, but is now in good shape. I’ll publish a detailed post about that process soon.

The house is also insulated! I’m not going to lie, it was beginning to feel like this day would never come. We’re using spray polyurethane foam (SPF) insulation along the roofline, exterior walls, and crawlspace walls. The spray foam is from Premium Spray Products and was installed by Advanced Energy Insulation (AEI). GreenShortz is producing a short video about the spray foam, which should be online soon.

Happy Radon Action Month!

The Environmental Protection Agency (EPA) has designated January as National Radon Action Month. Most people are surprised to learn that radon is the second leading cause of lung cancer in the US, after smoking; exposure to both radon and smoking multiplies the risk of developing lung cancer. Radon is a naturally occurring gas that forms from the breakdown of uranium in soil, rock and water. It is also colorless, odorless, and tasteless, making it impossible to detect without special equipment. The higher a home’s radon level, the greater the health risk to occupants. Radon can be found all over the US, and average levels are particularly high in the metro Atlanta region (Figure 1).
