American Insulock Inc. has entered into a contract with a United States property developer for a quantity of 10,000 blocks to build four houses in Payson, Ariz. Insulock International Inc., a wholly owned subsidiary of American Insulock Inc., has blocks in inventory and has begun additional production for the order.

The company’s core business is the manufacturing and distribution of its brand of insulating concrete forms, known as INSULOCK Blocks. The blocks are made of polyurethane rather than polystrytrene (Styrofoam). American Insulock’s board of directors made a decision to concentrate its efforts in the Southwest United States where its production facility is located.
