Using ICF is likely to get you to a near net zero energy or net zero energy standard for your new home. Step 1: The first step to building an ICF pool is excavation.While many builders are having to build thicker walls or add exterior insulation to achieve the new standards being set through building codes and ICF wall will meet even the new city of Vancouver’s high energy efficiency standard.Effective insulation or real thermal resistance. High effective insulation value – meets the new energy requirements being introduced into building codes across North America.Concrete can safely be poured in cold weather as the ICF insulates the concrete against freezing – make sure to consult your engineer or batch plant before pouring concrete in below freezing conditions.
Better curing in the ICF form means less chance of cracking or failure as a result of a poor cure Logix Pro These fully assembled blocks feature rugged 2 3/4 foam panels for a typical wall assembly R-value of R25. The new home smell will never be replaced with the damp musty smell of mold Plus they are mold, insect and rust resistant.
By keeping the basement rooms dry there will never be any risk of mold or mildew growth. BUILD FOR LIFE LEGACY BLOCK IS THE ANSWER Legacy ICF Blocks have a 5-hour fire rating, can withstand category 5 hurricane force winds and an 8.5 seismic event. However, this process is finished before the blocks leave the factory, and long before a home-owner ever takes occupancy of their new ICF home. The fire-retardant that is incorporated into the blocks will off-gas slightly in the factory. ICF blocks are, in fact, made of expanded polystyrene an important difference is that when ICF blocks are made, no CFCs of HCFCs are used in the forming process. ICF blocks are not Styrofoam, a common misconception. Concrete is made up of natural minerals, and recycled materials, including crushed concrete, none of which change its inert nature. Insulated Concrete Forms (ICF) are made from Expanded Polystyrene and unlike many of the materials used in construction, ICF’s and concrete are practically inert compounds, meaning they do not off-gas. In reality ICF was a Canadian invention, patented in Canada by Werner Gregori in 1966 and in the US in 1968 it has been around for a long and has improved the durability, comfort and energy efficiency of homes for over 40 years. As an industry we tend to get stuck with what we know, and can be very reluctant to try anything that might seem new. 
At the time of writing this article, the purchase price of a regular 16 x 48 ICF block from a local dealer is in the 22-25 range, depending on what region/country it is purchased in. While I see much greater adoption of this technology today than in the early 2000’s, I am still surprised that more builders, designers and engineers do not use it. Insulated concrete forms (ICFs) are typically purchased from a local lumber yard or building material retailer. While it took a few years to make a complete switch, every foundation we pour today is done with ICF. We began using Insulated Concrete Forms (ICF) in 2003 (photo above) and I wish we had discovered this system much earlier.
