I had an install 4-10-17 of Thermal Guard (reflective roof barrier), solar attic fan, blow-in insulation, eco-box. the attic temp before installation was 130 degrees at 1:00pm. Today during post inspection follow-up the attic temperature was 90 degrees at 1:00 pm. Wow! The installers were prompt, courteous, quick, efficient, cleaned up before leaving. EHS will track my electric bills for 1 year for effectiveness. The sales person (Chris) was knowledgeable, courteous. I am very happy with my investment.
