![]() ![]() We want peace and quiet and the time to relax. We walk inside our front door from our hectic day at work or with the kids. We all want to feel safe and comfortable in our homes. Wouldn’t it be great to come home to a house that’s always perfectly warm? How about never having to pay a heating bill again? A modern home that spacious, bright and energy efficient. Imagine being able to get all the features you dreamed of from your new home without any trade-offs. Whether it’s an open plan kitchen-living room, or large glazing that opens out to a garden. Vinyl is a poor insulator, but EPS inserts can be added to one side of the cavity if needed.We all start our house building journey with a long list of ideas, built up from years of dreaming of owning our own home. These are best suited for projects where the form will double as a final finish, such as fish farms, car washes, and wastewater tanks. Unlike CMU, though, they do have some insulating value, and finishes attach directly to the block without furring. Made from wood fiber and cement, these blocks mimic concrete masonry units in size, weight, and shape. The forms can be shaped with standard carpenter tools. Stuccos and plasters can be applied directly to the block without mesh and without sheetrock and still meet code. They need less bracing, and nails and screws hold wherever they are driven, making interior and exterior finishes easy to apply. The blocks are extremely robust, and stand up well to high-slump mixes and extra vibration. This typically means higher shipping costs in locations outside the southwestern U.S. and larger ones need to be craned into place. They’re considerably denser-and heavier-than regular ICFs a 48”x16” block weighs nearly 50 lbs. Because of the extra foam, they offer higher R-Values than their all-foam counterparts, and use about half as much the concrete. Made from a blend of EPS and Portland cement, these blocks are termite-proof, fireproof, and will not melt or burn.Īll are screen-grid blocks, meaning the concrete forms a series of columns and beams (usually every 16 inches on center). Ask to tour a jobsite and get references from other customers.Ĭomposite ICFs/Insulated Concrete Blocks (ICBs): Visit the manufacturers’ websites and sit down with the local distributor. In summary, these charts are a good place to start in selecting the best form for your project, but additional research will be needed. Work with a distributors that will answer questions, rent bracing and other equipment, and provide immediate assistance if you come up short on anything. Even more important than cost is the installer’s experience and familiarity with the forming system.įor do-it-yourselfers, manufacturer support is critical. Reversible interlocks and specialty forms can make installation go faster and reduce waste. Panel systems (knockdown forms) reduce shipping, but require more labor as jobsite assembly. The thickness of the foam sidewalls, which affects form strength, insulation value, and amount of raw material used, also varies.įreight is a significant factor in pricing, which is why the chart notes the location of molding facilities. Careful readers will notice a few waffle- and screen-grid systems still on the market, which use far less concrete, but require more engineering.Īctual core widths vary widely a six-inch nominal wall may vary from 5.5 to 6.75 inches, which accounts for the variability in the “Sq. ![]() However, some are 12″ or 18″ high, and a few are installed as vertical planks. Flat wall ICFs measuring 48″ x 16″ have become industry standard. ![]()
