How we sold 2006 spec, first we asked a question… What technology will revolutionize the housing industry? Hint: it has nothing to do with construction…

Answer… Low Cost Infrared Cameras

OBSOLETE COMPETITION

BUILDING SCIENCE RULES TO LIVE BY · Driving Forces Move More to Less: - More Heat to Less Heat - More Pressure to Less Pressure - More Humidity to Less Humidity · Gravity Makes Things Fall

BUILDING SCIENCE FIBROUS NSULATION = AIR BARRIER Resists Heat Flow Air Flow …need Air Barrier… (any solid material that blocks air flow including sealing at edges and seams) …on all six sides… …in direct contact with insulation (alignment)
