The thermal conductivity of the polystyrene used is 0.0357 W/m²K. The U-values (thermal transmission values) range from 0.210 to 0.52 W/m²K, depending on the block size and polystyrene thickness.

The polystyrene density ranges from 27-30 kg/m³ for standard blocks, while the block weight varies between 12-33 kg depending on size and type (normal or lightweight).

Normal-weight blocks have an average compressive strength of 7.5 N/mm², whereas lightweight blocks have a compressive strength of approximately 3.2 N/mm².

LAST-A-FOAM R-9300 thermal blocks provide high compressive strength (350 to 2,100 psi), resist moisture, prevent corrosion, and maintain physical properties over time. These blocks also arrive pre-cut with anchor bolt holes for quick installation.

Yes, they contribute to energy efficiency by reducing thermal bridging and lowering energy costs. LAST-A-FOAM R-9300 blocks are compatible with LEED certification and do not release harmful chemicals into the soil.

Lightweight blocks weigh less (12-21 kg) and have lower density (625-1050 kg/m³) compared to normal-weight blocks, making them easier to handle but with slightly reduced compressive strength.

These blocks are ideal for industrial buildings, cold storage, structural supports, insulated metal panels, equipment bases, and perimeter protection due to their high insulation and structural properties.
