Insulation is what TRUEFOAM Limited is all about. TRUEFOAM has been making insulation products in Atlantic Canada since 1968. Over the years, TRUEFOAM's product line has evolved from simple foam boards to advanced construction systems and specialized packaging. But it all remains based on a single material: expanded polystyrene. Expanded polystyrene, or EPS for short, is a simple material with a unique combination of qualities. It offers high resistance to the passage of heat energy, making it a very effective insulator. It is also economical, offering high R-value per dollar.
