The Perfect Block is a wall building system made from recycled foam and cement that is filled with steel reinforced concrete. This type of form is called an insulated composite concrete form, or ICCF. It creates a permanent insulated wall once the concrete cures.
The company says its blocks help resist fire, wind, and pests, while keeping heat and cool inside better than standard wood framing. The forms are sized to stack quickly, they can be cut with common tools, and they are designed to reduce jobsite waste by reusing offcuts.
The system is promoted for houses, schools, sound walls, and rebuilding in disaster prone areas. It can be finished with stucco or interior plaster without extra layers in many cases, which can simplify cladding.
Independent code evaluations exist for this product line. City and third party documents describe how the wall system can be used, which construction types it fits, and the conditions for installation. These approvals do not replace engineering and local code checks, they set the baseline for safe use.
ICCF and ICF walls in general are known for continuous insulation and tight air sealing. This helps lower heating and cooling needs, which is why these systems are often chosen for high performance homes.
Bottom line, The Perfect Block is a recycled material wall system that targets safety and energy savings with formal code pathways already defined. It is a practical option to consider when resilience and lower energy use are a priority.
