Is the Fox Blocks product rated by ‘Energy Star’?
Energy Star does not evaluate or rate insulation products. Every Fox Blocks home when tested by an Energy Rater, can meet and exceed the Energy Star home standards and achieve a 5 Star rating and a ‘HERS’ score well below the minimum Energy Star requirement of 85, or in Canada, higher than an EnerGuide rating of 80.
ICFs and Severe Weather
The steel reinforced concrete, which can cure stronger than normal concrete because of the foam insulation, can withstand winds of over 200 MPH, and projectile debris traveling over 100 MPH. There are dozens of eye witness examples of ICF homes taking EF5 tornadoes head on with the walls still standing.

Do ICFs require a special concrete mix design?
