EPS 17kg/m³
Insutech EPS 17 is a white expanded polystyrene foam sheet at a nominal density of 17 kg/m³, delivering improved mechanical strength and thermal performance over the entry-level Insutech EPS 14 grade.
Engineered for the job it protects.
Insutech EPS 17 is a white expanded polystyrene foam sheet at a nominal density of 17 kg/m³, delivering improved mechanical strength and thermal performance over the entry-level Insutech EPS 14 grade. Precision-cut from injection-moulded polystyrene blocks, it offers excellent dimensional consistency and integrates seamlessly into both new construction and retrofit insulation assemblies.
Insutech EPS 17 provides enhanced compressive resistance alongside a thermal conductivity of ≤ 0.036 W/mK, making it effective at reducing heat flow through building envelopes. By limiting thermal bridging and minimising energy losses, it contributes to measurable reductions in electricity bills and supports the delivery of energy-efficient, sustainable buildings.
Board thickness: Available in 20 mm – 100 mm and can also be customized.
- Enhanced thermal insulation with ≤ 0.036 W/mK thermal conductivity
- Improved compressive strength over EPS 14 grade
- Reduces electricity consumption and operating energy costs
- Reduces CO₂ emissions through superior insulating performance
- Lightweight and easy to handle and install
- Prevents moisture infiltration in walls and ceilings
- Resistant to moisture and chemical attack

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.
