Iso Foam
Insutech IsoFoam is a rigid, blue Extruded Polystyrene Foam (XPS) board manufactured at a density of 32–36 kg/m³ through a continuous extrusion process.
Engineered for the job it protects.
Insutech IsoFoam is a rigid, blue Extruded Polystyrene Foam (XPS) board manufactured at a density of 32–36 kg/m³ through a continuous extrusion process. Available in lapped or straight edge profiles and a wide selection of thicknesses, IsoFoam offers a well-balanced combination of thermal efficiency and mechanical strength suited to a broad range of building insulation applications.
With a thermal conductivity of 0.033 W/mK and compressive strength of 250 kPa, Insutech IsoFoam effectively reduces heat transfer through roofs, walls, and floors — minimising reliance on air conditioning and heating systems and translating directly into lower electricity consumption, meaningful energy cost savings, and reduced CO₂ emissions throughout the building’s service life.
- Strong compressive strength: 250 kPa @ 10% deformation
- Consistent thermal insulation with 0.033 W/mK thermal conductivity
- Significantly reduces electricity consumption and energy operating costs
- Reduces CO₂ emissions through superior insulating performance
- Low water absorption (≤0.7% by volume) for long-term moisture resistance
- Prevents moisture infiltration in walls, ceilings, and floor assemblies
- Lightweight and easy to handle, bond, and install on site

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.
