EPS 30kg/m³
Insutech EPS 30 is a white, high-density expanded polystyrene foam sheet at a nominal density of 30 kg/m³.
Engineered for the job it protects.
Insutech EPS 30 is a white, high-density expanded polystyrene foam sheet at a nominal density of 30 kg/m³. Designed for applications where both high compressive loads and excellent thermal performance are required, Insutech EPS 30 is ideal for heavy-duty floor insulation, load-bearing roof assemblies, and below-grade wall and foundation insulation. It is precision-cut from injection-moulded polystyrene blocks to exacting tolerances.
With a thermal conductivity of ≤ 0.033 W/mK and compressive strength of ≥ 200 kPa, Insutech EPS 30 provides premium insulation efficiency — substantially reducing heat transmission through building structures, lowering energy consumption, and generating significant long-term savings in electricity and HVAC operating costs. Its superior resistance to moisture, chemicals, and compressive loads makes it a robust long-life insulation solution.
Board thickness: Available in 20 mm – 100 mm and can also be customized.

Application, Step by Step.
Remove dust, grease and loose particles from the substrate so the insulation boards can sit completely flush against the prepared surface.
Measure carefully and cut the boards to size with a sharp blade or hot wire, keeping the edges square for tight and accurate joints.
Apply a compatible adhesive or fix mechanical fasteners appropriate to the substrate, following the specified coverage and spacing.
Position each board and press it firmly into place, butting boards tightly together and staggering the joints between rows for stability.
Close all joints and gaps with compatible tape or filler so the insulation layer forms one continuous, unbroken thermal envelope.
Apply the specified screed, render or cladding over the boards to protect the insulation and complete the build-up as designed.
