Technical Data: EPS (Expanded Polystyrene)

EPS isn't just foam insulation, it's an innovative building material that lends to the design and structural integrity of many building projects. Since the 1950's, EPS has been recognized as a mainstream insulation material, but over the past decade new applications using EPS have exploded, and EPS now serves as a powerful design element. Polycore Canada utilizes a Type I EPS in its standard line of wall and roof series, product sourced for our operation from Foam Molders Inc. of Post Falls Idaho. Specifications and data presented here are obtained from Foam Molders Inc. publications and their company service offices.

Thermal Values of EPS

EPS insulation can considerably reduce heating and cooling costs in buildings. Its uniform, closed cellular structure is highly resistant to heat flow and it also offers a stable R-value over the life of a structure. When used in typical applications, its properties as a rigid insulation prevent the thermal siphoning that can cause other insulation methods to under perform their ratings. Whenever primary design considerations include energy efficiency and cost effectiveness, EPS is the insulation of choice.

Environmental Facts about EPS

No CFCs - EPS has never been made with any CFC, HCFC, or HFC gases. CFCs have been shown to be harmful to the earth's ozone layer.
Landfill Safe - EPS is inert and stable. It will not leach out toxic chemicals, heavy metals or create dangerous decomposition gases such as methane, a "greenhouse" type gas. In landfills, EPS helps to keep the ground stable, important when the area is reclaimed for development.
Waste to Energy Safe - EPs provides a clean source for WTE incineration systems. The simple chemical make-up of EPS is carbon and hydrogen, elements found in wood and other organic materials. EPS ash is therefore non-toxic - no unsafe chemicals or heavy metals are produced when burned as a fuel.
Recycling - EPS is 100 percent recyclable, and can be recycled in various ways. The rigid product can be mechanically broken apart, making a lightweight, granular product that has many uses. EPS is also thermally processed to make a resin that is used as a raw material in the manufacture of a number of valuable products for use in homes, schools and offices.
