We chose Quad-Lock forms because it gave us the ability to increase the R-value over standard ICFs. Whereas wooden forms are removed (and reused) after the cement wall is poured and hardens, the Quad-Lock forms stay in place and serve as insulation (unlike most homes, our crawl space is insulated). Here you can see the 4 1/4″ outer wall and the 2 1/4″ inner wall, yielding R-3o.Usually, the forms for a foundation wall are made using wooden forms, but we used Quad-Lock ICFs (insulated concrete forms). They’re made of expanded polystyrene and look a lot like Legos.

Incorporating Quad-Lock Insulating Concrete Forms into our new housing made this job a whole lot easier. We effectively tripled our homes’ R-values over standard construction materials, an important accomplishment in the heat-sapping winters in Yellowstone. Additionally, our ICF walls are excellent heat sinks that augment the effectiveness of the houses’ passive solar design, maintaining a comfortable living environment year-round and minimizing the number of days we have to heat the buildings. Without the energy-saving qualities of Quad-Lock walls, there’s absolutely no way we could have submitted these homes for LEED certification.

After exhaustive comparisons of many different floor and roof systems, I found Quad-Deck to be the safest, highest performing, and most cost effective system available based on a life cycle cost analysis. This analytic method is the only measure of any building that is truly meant to last. Quad-Deck‘s function as a thermal mass heat sink, its solid feel underfoot, flexibility of design vs. other RC systems, ability to span long distances, and function as a base for a green roof are just a few of the reasons why Quad-Deck is my horizontal structure of choice.”
