"A common cause that I have seen is undersized gas supply piping, especially when a combustion appliance is added to the line. Undersized gas supply pipe = lower gas pressure => high CO"

Brad Cook replied to Patrick Michaelyan's discussion Closed-Cell Foam & Brick Walls
"Here in central Vermont, we see houses from the 1800s with brick walls as part of the foundation, but the brick is not structural. Large slabs of granite are holding up the typical 8x8 sill beam. If we were to spray SPF (Spray Polyurethane Foam) on…"

Brad Cook replied to Bud Poll's discussion Calculating attic ventilation
"Everything that I have read on the subject agrees with what John Nicholas presented. What appears to be a big misconception by many people is that we ventilate a roof to make it "cold" to minimize ice dams. The real reason is that the…"

Tools of the Trade

A hammer and a saw used to be the key tools for home contractors. Today, the best-in-breed also use high-tech equipment while performing a professional energy audit or verifying that construction has been done correctly.
