EPS (expanded polystyrene) and XPS (extruded polystyrene) are two common types of rigid foam insulation used in building construction. Both materials are made from polystyrene and have similar physical properties, but there are some differences in how they are manufactured ...

Below-grade insulation needs to provide thermal protection and moisture resistance for building foundations and basements. Below-grade insulation materials must be able to withstand the harsh environment of the soil, resist moisture and prevent heat loss. Suitably faced polyiso panels meet ...

R-value is a measure of resistance to heat flow through a given thickness of material. In theory, the higher the R-value, the greater that resistance. That’s fine as far as it goes. Unfortunately, R-Value has taken hold in the consumer’s ...

What is extruded polystyrene insulation made of? Extruded Polystyrene (XPS) is a type of foam insulation material made from polystyrene beads that are melted and extruded into board-like form. XPS is known for its high insulation value, durability, and moisture ...

Polyiso is one of the nation’s most widely used and cost-effective insulation products and has been cited by the U.S. Environmental Protection Agency for its responsible impact on the environment. Polyiso is a closed-cell, rigid foam board insulation. Because of ...

EPS is everywhere: It holds your food, secures items in packages, provides insulation in homes and industry and it’s even in your bike helmet. It’s also known as plastic #6, which you’ve seen used in plastic cups and CD and ...

Reduce, Reuse, Recycle, commonly referred to as Recycling is one of the most feel-good and useful environmental practices around. The benefits go way beyond reducing piles of trash — recycling protects ecosystem diversity with the added benefit of saving energy, ...
