ICF
building also has major impacts on energy use.
Significant savings are experienced in an ICF home
compared to traditionally built lumber homes. (Click
on the Phoenix Warranties link to the left for
details about our industry-leading 72% Energy
Savings Warranty.)
The
mass of the concrete in the exterior ICF walls
contributes to the energy efficiency, as heat
transfer between the inside and outside of the
wall is extremely low.
Add
to this the insulating effect of the interior and
exterior polystyrene and a typical ICF wall’s
performance R-value is equivalent to a wood frame
wall insulated to between R-38 to 42 – and of
course to build that level of insulation in a wood
frame wall would be cost prohibitive. |
