Composite ICCF Block for Sustainable, Eco-Friendly Housing in Arizona.
Innovative ECO-Friendly Building Material
The Perfect Block™ is an insulated composite concrete form (ICCF) made of a blend of recycled expanded polystyrene (EPS), also known as Styrofoam™, Portland cement, water, and proprietary admixtures. This mixture provides the block with exceptional insulating properties and makes it resistant to fire.
The best part is that 100% of the EPS used in these blocks is recycled, which helps to reduce waste in our landfills. This eco-friendly construction solution offers not only superior performance but also a sustainable and responsible choice for builders and homeowners alike.
Superior Building Material
The insulation power of The Perfect Block™ is a result of recycling EPS. This modern-era waste material is typically found clogging up landfills, but we’ve transformed it into an innovative building solution that’s both energy-efficient and fire-resistant.
Once assembled, the ICCF blocks can be filled with concrete and reinforcement steel (rebar) to form a strong and durable framework. This monolithic “post and beam” grid provides a sturdy structure for a wide range of building components.
Why choose The Perfect Block?
Superior Strength
ICCF wall are at least 700% stronger than stick framed walls and resist 250mph winds.
Cool Insulation
Greater insulation that 2x4 or 2x6 batted insulated walls.
Fire Resistance
ICCF walls do not burn. The Perfect Block has a 4-hour fire rating from Intertek testing.
Termite Resistance
There is no food source for termites, insects, or rodents. No dry rot can occur.
Benefits of “The Perfect Block” over other ICCF materials.
The “Greener” Choice.
TPB is the "greener choice" - White block is made of virgin molded EPS. There is little, if any recycled material in White block. In strict contrast to White block, each TPB has nearly 87% of its volume made of only 100% clean recycled EPS greatly reducing waste that was headed for the landfill.
Invulnerable to UV Damage
TPB Block Surfaces Can Remain Exposed For Years Without UV Radiation Exposure Damage. In contrast, white block is vulnerable to UV radiation deterioration almost immediately and must be covered soon after construction to prevent UV radiation deterioration and mechanical damage
Unique “Toothing” Structure
"Tooth" is a term to describe a surface's ability to hold or grip a substrate. TPB's inherent textured (slightly rough) cement like surfaces can hold exterior stucco and interior plasters or drywall joint compound or adhesives without additional furring, layer of rigid foam or wire lath and tar paper, or house wrap eliminating many costly additional materials and labor-intensive steps required with other building materials to clad exterior and interior walls.
