BetterBlock ICF Forms SPEC SHEET
Redefining simplicity, strength, and efficiency with metric ICF construction.
Welcome to the future of insulated concrete formwork. The BetterBlock 8th Generation ICF System is the result of hands-on expertise and real-world experience feedback. Engineered to overcome common issues in previous ICF designs, we’ve added smarter geometry, metric standardization, and our exclusive T-Form innovation to accelerate and strengthen ICF construction projects globally.
- Locally Manufactured: BetterBlock is now proudly produced for Central America, South America and The Caribbean, ensuring significantly faster delivery times and eliminating delays related to international shipping and customs.
- Knock-Down Format (KD): All blocks are delivered separated (flat-packed), maximizing the quantity that fits per shipment and dramatically reducing transportation costs and on-site storage requirements.
- Improved Foam Panels: We use a denser, more impact-resistant EPS foam, which delivers enhanced structural stability, greater soundproofing, and improved long-term durability.
- Reinforced Plastic Webs: The number of plastic webs has been strategically reduced, while their strength has been increased, making each form quicker to assemble without sacrificing rigidity or performance.
- Stubby Interlocking Teeth: Our new 8 mm stubby teeth improve stacking alignment, reduce breakage, and form a stronger bond between forms during pours.
Each BetterBlock form features:
- 5 cm thick EPS foam panels,
- Core options of 10 cm, 15 cm, or 20 cm, and precision cut guides every 20 cm to keep it aligned with internal webs. Built for the metric system and optimized for modern jobsite demands, BetterBlock is setting the new standard in ICF construction worldwide.
- R-Value (Thermal Resistance): BetterBlock ICF forms provide a nominal insulation of R-22.5 (RSI ≈ 4.0). When installed as a complete wall assembly—including the concrete core and typical interior/exterior finishes, the effective assembly R-value is ~R-32 or higher (RSI ≈ 5.6+), depending on the finish materials and detailing.
- 26 kg/m3 EPS Density

Better Block Specs and Measurements
🔹 Group 10 – 10 cm Concrete Core
▪ Straight Block
- Core Width: 10 cm
- Foam Sides: 6.5 cm (each side)
- Total Width: 23 cm
- Length x Height: 100 cm x 40 cm
- Use: For non-load-bearing interior partitions and light framing applications.
- Features: Now with stubby 8 mm teeth for a tighter form connection that resists cracking during transport and installation.
▪ T-Block
- Main Core: 10 cm
- Branch Core: 10 cm
- Use Case: Connects interior walls to exterior main walls without field cutting.
- Stubby Teeth Benefit: Reinforced junctions hold tighter under pressure from multiple pour directions.
▪ Corner Block
- Core: 10 cm
- Use: Tight interior corner transitions with full insulation and flow continuity.
- Improved Locking: The stubby teeth ensure clean alignment and prevent corner shift during reinforcement or concrete placement.
🔹 Group 15 – 15 cm Concrete Core
▪ Straight Block
- Core Width: 15 cm
- Foam Sides: 6.5 cm
- Total Width: 28 cm
- Length x Height: 100 cm x 40 cm
- Use: Perfect for residential exterior walls or mid-rise applications.
- Stubby Teeth Advantage: Prevents block movement under load and enhances vertical stacking speed.
▪ T-Block
- Main Core: 15 cm
- Branch Core: 10 cm or 15cm
- Use Case: Simplifies connection between structural walls and partitions.
- Interlock Note: Stubby teeth prevent joint expansion at this crucial high-tension intersection.
▪ Corner Block
- Core: 15 cm
- Application: External corners for homes and commercial projects.
- Key Benefit: New tooth design ensures perfect alignment at tight junctions and eliminates thermal bridging at corners.
🔹 Group 20 – 20 cm Concrete Core
▪ Straight Block
- Core Width: 20 cm
- Foam Sides: 6.5 cm
- Total Width: 33 cm
- Length x Height: 100 cm x 40 cm
- Use: For high-load, multi-story, or hurricane-resistant construction.
- Stubby Teeth Upgrade: Enhanced grip during multi-level pours and long wall runs.
▪ T-Block
- Main Core: 20 cm
- Branch Core: 10 cm or 15cm
- Use Case: Joins thick structural perimeters with lighter internal divisions.
- Connection Strength: Stubby interlocks resist lateral shift from unequal concrete pressure.
▪ Corner Block
- Core: 20 cm
- Use: External structural corners under heavy load
- Precision Fit: 8 mm teeth maintain perfect geometry and prevent any rotation or bulge under rebar strain.
✂ Cut Points Every 20 cm
Every form includes pre-marked cut guides spaced every 20 cm, aligned precisely with internal plastic webs. This reduces waste and ensures that even trimmed blocks retain structural integrity and stacking capability.
🧩 T-Form – Addition
Your most time-saving innovation yet. The BetterBlock T-Form redefines how you create wall intersections. Traditional methods require time-consuming field cuts and precise alignment—we’ve solved that with:
- Factory-made precision
- Improved concrete flow and rebar continuity
- Available for all groups (10 cm, 15 cm, 20 cm)
🌍 Metric-Based, International-Ready
BetterBlock is fully metric—from foam thickness (6.5 cm) to concrete cores (10, 15, 20 cm). This simplifies architectural design, engineering calculations, and logistics on any international site.
