ICF vs. Wood Framing
Compared to Insulated Concrete Form walls, wood framing falls short in terms of durability and resistance to external forces. ICF walls can withstand extreme weather and winds of up to 250 mph (402 kph), while wood-framed walls are vulnerable to high winds and impact. Wood is also susceptible to termites, mold and costly water damage as opposed to low-maintenance ICF walls, which are mold- and pest-resistant. In the event of a fire, ICF walls have a fire rating of 4 hours, while wood is only rated for 45 minutes, providing occupants more time to safely evacuate.
Wood-frame structures have batt insulation in the cavities between the wood studs, but every stud serves as a thermal break where there is a gap in the insulation. These thermal breaks, or thermal bridging, allow greater air flow through the wall, leading to inconsistent interior temperatures and reduced energy efficiency. Insulated Concrete Form walls, on the other hand, have continuous interior and exterior insulation, maximizing energy performance. This translates to up to 60% lower heating and cooling bills, reduced carbon footprint and a noticeably more comfortable living space.
