The vertical concrete columns inside each block are 5.5 inches in diameter.

Yes. ThermoBlock is structurally engineered for multi-story and both above- and below-grade construction. Rebar is placed per engineering spec, typically using #4 or #5 bars.

Absolutely. ThermoBlock is ideal for below-grade applications due to its water-resistant, closed-cell polyurethane core and structural post-and-beam design. A waterproofing membrane and perimeter drainage system are recommended during installation.

Yes. For any below-grade use, a waterproofing membrane should be applied to the exterior face of the wall. The closed-cell foam resists water, but best practice (and code) calls for added protection.

• Length: 32 inches

• Height: 12 inches

• Thickness: 8 inches

• Each block covers approximately 1.77 sq ft of wall area.

• Form Cost Only: $18 per block

• Installed Cost: $22–$27 per sq ft depending on project complexity

• Form cost includes the blocks only; installed cost includes concrete, metal studs, labor, and full wall system setup.

Yes. ThermoBlock is Class 1 fire-rated (highest classification) and can achieve a 2.5-hour fire rating when used with a cementitious stucco finish and non-combustible roof deck.

Thermal bridging occurs when uninsulated materials transfer heat across a wall. ThermoBlock’s design eliminates thermal bridging by fully insulating around the internal steel structure.

Yes. ThermoBlock is designed to meet International Building Code (IBC) and California Building Code (CBC)standards. While an ICC-ES report is not currently published, we provide site-specific stamped engineering letters and attachment documentation as needed for permitting.

Drywall is fastened directly to the internal steel bracing strips within the block using standard drywall screws. No furring is required unless additional chases are needed for wiring.

You can route electrical wiring by:

• Cutting chases into the foam using a hot knife or router after stacking

• Embedding conduit during the build phase before the pour

• Surface-mounting wiring if desired, especially in retrofit applications

ThermoBlock is actively expanding through a licensed manufacturing partner program, offering exclusive territories to qualified partners across North America. Our goal is to meet the rising demand for high-performance ICF systems while empowering local partners to build successful, scalable businesses.

As a manufacturing partner, you gain access to our proprietary mold system, startup and operational training, and full branding support. With strong market demand driven by energy codes, disaster-resistant construction, and builder preferences, our partners are seeing significant growth in both residential and commercial sectors.

If you’re interested in bringing ThermoBlock to your region, we offer a structured onboarding process and help you launch with confidence.

Yes. ThermoBlock manufacturing can be mobilized using a 40-ft container or trailer-based setup, complete with foam injection, molds, and curing racks. Power can be supplied via generator or industrial grid connection.
