This is a lie. FEMA classifies both "Sprayed polyurethane foam (SPUF) or closed-cell plastic foams" as "Acceptable" for floors, walls and […]

Don't think of your house as a n=1 experiment

FEMA has really good engineering for flood-prone areas. If we stop listening to architects and contractors and start paying attention to people who provide direct instructions on how to do this stuff we can avoid a whole lot of heartache in the future.

Next I’ll nail through the rebate and weather strip in one shot. See! Nailing. Boo-yah!! Too easy. Finally I glue a piece of 1/2″ plywood to 4″ of thermax foam […]
