Of all construction materials, concrete is one of the most resistant to heat and fire. That fire resistance gives houses built with ICFs (insulating concrete forms) certain safety advantages. And those advantages give you yet another reason to consider using ICFs for your custom home.   How well do ICF walls hold up in a fire? Unlike wood, concrete does not burn. Unlike...

What is R-Value and why is important to know with ICFs? R-value is a measure of thermal resistance, or ability of heat to transfer from hot to cold, through materials (such as insulation) and assemblies of materials (such as walls and floors). The higher the R-value, the more a material prevents heat transfer. R-value depends on materials' resistance to heat conduction, as...
