EXPOL history in the making

In 1976 a young Terry Mischefski bought a block of expanded polystyrene and created a small piece of packaging, that would end up having a big impact on Kiwi homes.

After a move to Auckland and many successful years in the packaging game, the decision to turn his attention to polystyrene insulation in the 1990s would see EXPOL undergo massive growth. Consumers embraced the exceptional insulation properties of the lightweight board.

As demand grew, EXPOL grew its product range to the complete range of construction solutions you see today.

Today Terry is still at the helm of EXPOL and has been joined in the business by his son Mark. With a continued commitment to leading edge manufacturing and customer fulfillment, the innovation that saw Terry revolutionise polystyrene packaging continues to this day.
