Retrofitting a conical roof onto a segmented wall. You probably can't tell from the pics, but the top of the existing wall was out-of-level by almost 2". Good times. I keep meaning to drive by and get a finished shot – roof is standing seam copper. Reshared post from +Jesse Smith View this post on Google+ Post imported by Google+Blog […]

Really rigorous, good content. Well worth it. Will try to blog in more detail about at some point.

Really strange device mounted into the flue of a boiler I tested yesterday
The holes are designed to create turbulence. A thermostatically activated fan on the back (not pictured) blows air through the holes to recover flue pipe heat into the conditioned space. One small problem is the desirability of having flue gases exit the building. Flue gases on this thing spilled like crazy from the boiler into the living space probably because […]

Last one for the day
A lot of lying-liar-charlatan-moron-spray-foam contractors in and around the NJ shore are claiming that "*Spray Applied Closed Cell Foam Insulation is the ONLY form of insulation material that is approved and supported by the Federal Emergency Management Agency (FEMA)". This is a lie. FEMA classifies both "Sprayed polyurethane foam (SPUF) or closed-cell plastic foams" as "Acceptable" for floors, walls and […]

Flood openings for buildings not located in coastal high hazard areas

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. Good luck! Embedded Link Design and Construction Guidance for Breakaway Walls Design and Construction. Guidance for Breakaway. […]
