EXPOL cladding insulation protects buildings and people who live and work in them. Approved for Exterior Insulation and Finishing Solutions (EIFS) use, EXPOL cladding insulation products are helping to create a more energy efficient New Zealand.

EXPOL cladding insulation products have been designed to provide long-lasting R-value performance that meets or exceeds Building Code regulations. They are also used as insulation for walls, ceilings and roofs.

Creating a total envelope of thermal protection around a building with EXPOL polystyrene insulation boards is the best way to reduce heat loss, draughts and moisture.

EXPOL’s rigid polystyrene boards do not sag or slump over time, ensuring that thermal gaps do not occur and the R-value of the cladding insulation is retained for the life of the building.

Product could be damaged and warranty will be void.
