Design specifications Component and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

The assembling of walls requires four styrofoam pieces, which include the Standard and Lintel Block, a Plug, and the End Cap. The Standard Wall Block and Lintel/Header Block comprise the main pieces. These blocks are 121.9 x 30.5 x 20.3 cm³ and weigh about 1.4 kg. The blocks interlock for assembly. It uses 3/8 rebar and concrete into holes/studs every 40.6 cm on-center throughout the wall and the same is done through the lintel block every 120 cm from the ground to structurally tie the building vertically and horizontally.

Technical support Technical support provided by

Lazarian World Homes does not provide ongoing technical support. The user would need to contact a general building contractor.

Replacement components Availability of replacement components (in-country, by order,...)

Since Lazarian World Homes builds homes and does not sell the blocks as a separate product, a user would likely have to obtain additional blocks from elsewhere.

Lifecycle Disposal and warranty

Lazarian World Homes projects an economic life of 40-50 years. They also suggest that the blocks can be recycled by grinding up the foam and mixing it into gardens for easier watering, or mixing as an additive into concrete blocks.

Safety Potential hazards / risks related to operation of this product

Workers are subject to the general dangers of a construction site that include working from heights and with machinery and sharp tools. EPS and EPU are combustible and therefore many codes require a thermal barrier such as drywall or plaster as a finish on the ICF.

Complementary technical systems Performance of this product is improved with another technology (eg. Cookstoves and Wind-blocking skirts)

The Polyurethane Portable Factory is one of the machines used to create the blocks and can be purchased from E-Z Flow Foam Packaging Systems.
