Insulated Concrete Foundation Forms/Walls - October 20th 2006
Q: I am building a new home and the builder has suggested using insulated concrete forms for the foundation. What do you think of this?
A: I agree with your builder since I believe that one day all homes should be built with Insulated Concrete Forms. ICF foundation walls are built with a reinforced concrete core, between two layers of expanded polystyrene foam insulation. This method is known to be more effective in reducing drafts and cold spots, especially in basements.
Typically, there is an R-Value of R-22 or even greater. Definitely an energy efficient way to go. To find out more it's best to contact the manufacturer directly.
