250 × 200 × 400 mm Insulated Block (60 mm EPS)
250 mm wall: thicker concrete shells around a 60 mm EPS core. More thermal mass and acoustic separation — pick it when the plan allows extra thickness.

The U-value belongs to the full wall assembly (shell thickness, plaster, joints), not the block alone, so we do not publish a single figure. A plastered 10″ insulated wall is designed to support Estidama Pearl and Al Sa'fat thermal-envelope targets — share your assembly and target U-value and we will confirm the approach for your project.

Side-by-side decision matrix: hollow vs. solid vs. insulated, by load class, fire rating, U-value and use case.
