Happy ! Today we are going to profile a product that was invented in the late 60s but has recently seen a surge in the Western NY Area:
Insulated Concrete Forms (ICF). ICF block is a system of form work consisting of thermal insulation, concrete, and steel reinfocement. This system can be viewed as adult legos! Blocks (or forms) are dry stacked to create your exterior footprint. Once the system has been reinforced, concrete is poured between the two thermal insulation panels to develop your exterior structure.
This system has seen a recent surge due to its engery saving benefits. Let's take a look at the top three:
1. The two panels of continuous foam insulation provide an insulation R-value of R25 or higher. This is 18-26% higher than traditional wood frame construction. R-values tell you how well your insulation prevent heat from leaving or entering your home. The higher the value, the better your insulation is.
2. ICF construction provides an air-tight wall assembly, reducing drafting and improving thermal performance. It has been shown that ICF block reduces up to 60% lower air infiltration than traditionally-built walls. No more drafty windows and doors.
3. Thermal Lag. This refers to the delay of heat transfer through a wall. A higher thermal mass - ability to absorb heat - prolongs this delay. Why does this matter? Because, thermal lag preserves your interior temperature even as the exterior temperature changes. This allows your heating and cooling systems to stay inactive longer, saving you money!
ICF may be something to consider for your next project. Vanguard Interiors recommends this product and has designed several projects where ICF is the main component.
