Our story

EXPOL is the largest manufacturer and distributor of polystyrene products in New Zealand.

In addition to its EPS (expanded polystyrene) products, EXPOL also has a range of XPS (extruded polystyrene) and graphite-infused polystyrene products.

Recognising that things constantly change in the building industry, EXPOL uses state-of-the-art production equipment to cut blocks to any thickness customers require.

All EXPOL products are tested and meet industry standards and EXPOL underfloor insulation products are appraised by BRANZ.

A national network of manufacturing and warehousing sites and long-standing relationships with New Zealand’s largest building supplies retailers make EXPOL products easy to access throughout the country.

In response to customers' expectations, EXPOL manufactures environmentally safe products to help create healthy homes. The company also runs one of New Zealand’s largest polystyrene recycling plants, contributing to the sustainability of polystyrene building products. EXPOL EPS products do not use ozone-depleting gases.

Our History

In 1976 a young Terry Mischefski bought a block of expanded polystyrene from UEB Industries and created a small piece of packaging that would end up having a big impact on Kiwi homes. From his garage in Stratford, in the heart of New Zealand dairy country, Terry’s polystyrene packaging first caught the eye of Pye Electronics – an electrical equipment manufacturer which was using expensive moulding to protect fragile goods.

Terry had developed an innovative method for cutting polystyrene using hot wire and offered a cost-effective solution for short production runs. As interest grew, Terry moved to Auckland and officially started EXPOL in 1978. Just three years later Terry had a busy team working on packaging products for appliance, cosmetic and silverware manufacturers.

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 for underfloor insulation. As demand grew, EXPOL went on to add wall and ceiling insulation, waffle pods, geofoam and soft ground fill to its product range.

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 first spark of innovation that saw Terry revolutionise polystyrene packaging continues to this day.
