- Fox Blocks do not off-gas and are not manufactured using any gases that deplete the ozone or are harmful to the environment.
- Fox Blocks require low embodied energy to manufacture.
- Fox Blocks do not contain any materials, that promote mold or mildew growth.
- Fox Blocks are an efficient construction method thereby reducing the amount of construction waste, dust and air pollution in the building process.
- Building with Fox Blocks will save on heating and cooling costs because less air is exchanged between the outside and inside of your home. This also means a smaller more efficient HVAC unit is required for the home.
- Fox Blocks are sustainable. They will not rot or deteriorate for the life of your home.
- Fox Blocks provide a secure, durable, comfortable, long lasting building
The clear R‑Value of an Fox Blocks is R22, however current Energy codes recognize the lack of thermal bridging in an ICF and the contribution of the mass concrete on the influence of the thermal performance. Whole wall calculations indicate a Fox blocks wall assembly provides an R24 rating.
The continuous double layer (inside and outside) of insulation, the elimination of thermal bridging and minimal air infiltration through the mass concrete wall assembly, allows Fox Blocks walls to performance in the high performance wall assembly category. Completing the envelope with energy efficient windows and doors and roof insulation, Fox Blocks homes can easily meet and exceed energy code requirements and exceed the minimum requirements for Energy Star and EnerGuide. A Fox Blocks structure requires 44% less energy to heat and 32% less energy to cool.
