Amazon Forms One, Inc.
Amazon Forms Grid-WALL™ is the premier composite insulated concrete form (ICF) green building material. Made of cement and 100% recycled polystyrene (EPS), our unitary stay-in-place forms create a post-and-beam grid that is extremely energy efficient, durable, and strong. It is one of the most innovative building materials available today.
Concrete has been a choice building material for more than one hundred years. Modern homes made from concrete are safe, comfortable, easy to heat and cool, and will last for many generations. They have survived natural disasters such as floods, fires, hurricanes and tornadoes without structural damage. And concrete is made from readily available materials. For these reasons, concrete homes have been built all over the globe.
Amazon Forms Grid-WALL™ block's extreme design flexibility makes it ideal for homes, apartments, municipal and commercial buildings, but especially suited to EMS, Fire, Police, hospital, school, and elder care facilities. It can also be used for some basement walls, retaining walls, safe rooms, foundation stem walls, etc. (See special projects section for more information.)
We use EPS (Expanded PolyStyrene), a pelletized styrofoam commonly used in many packaging products, such as frozen seafood containers, computer and fragile electronics packaging, metal roofing insulation, etc. In 2004, we used over 90,000 cubic feet of recycled styrofoam in the manufacture of our products, saving our landfills valuable space and saving precious energy resources re-using an otherwise spent product.
Our blocks are easy to build with, easy to cut and shape, yet make an incredibly strong and energy efficient wall. When filled with concrete, they create a grid of solid concrete, 6 inches in diameter at its smallest . The finished ICF wall receives its real strength from this reinforced concrete grid poured within the blocks.

Energy Efficient!
Our modified 3-story showcase house is built on a 9,500 sq. ft. slab and features a main living area of 5,800 sq. ft. The electric bill for March 2005 was just $92
