Mansonville Plastics (BC) Ltd has been British Columbia’s lead in introducing and manufacturing Expanded Polystyrene since 1959. We have helped pioneer new and innovative ideas for our EPS products.

Mansonville Plastics (BC) Ltd is pleased to be working with the Building Science Centre of Excellence at BCIT for new and improved methods of energy conservation. As always, we are committed to support "green" building technology.

Expanded polystyrene is a light-weight, resilient, closed cell, foamed plastic ideally suited to all types of building projects where rigid insulation is needed.

Our EPS product line has the trademark of "Korolite™" and has been used in construction for foundations, walls and tapered roofs for both commercial and residential buildings.  For over 50 years, Korolite™ can easily satisfy any thermal requirement for perimeter and walls in a variety of systems – flat, slab or tapered sheets.

With its low cost, versatility and the highest R-Value per dollar, Korolite™ EPS rigid insulation is preferred by home builders, architects, specifiers and insulation application contractors all over North America. For specified applications, Korolite™ EPS rigid insulation meets or exceeds your building code requirements. Another application where Korolite™ EPS is used is as Geofoam voiding which is used under roadbeds on highways that span over marshy ground. Mansonville also provides Korofloat™ EPS for use in flotation for marinas, fish farms, and floating homes.
