EPS (expanded polystyrene insulation) is manufactured using beads of foam within a mould. Heat or steam is applied directly to the beads, causing them to expand and fuse together.

The foam that you formerly knew as styrofoam is actually expanded polystyrene foam or EPS. This material is made from polystyrene, a plastic that's often used to make clear products like food packaging or lab equipment.

Expanded polystyrene (EPS) is a lightweight and rigid foam material. It is a material of choice for the packaging and construction industry. It provides cost-effective solutions and energy-efficient insulation. It also acts as a cushion transport packaging material for shock-sensitive goods.

Common polystyrene foam insulation board is easy to burn, and toxic smoke produced by combustion. Even adding a flame retardant, the combustion can only reach B grade. 3. Material strength is poor, prone to crack and insulation shedding phenomenon is relatively common.

EPS and XPS are two common types of insulation made from the same base materials, resulting in similar polystyrene foam boards — but they are manufactured using two different processes. When comparing the two, there is very little difference between EPS and XPS insulation when it comes to quality.

EPS (Expanded Polystyrene) or “Geofoam” is gaining popularity as a widely acceptable and cost efficient construction insulation material. It is commonly used for structural fill material, elevated slab applications, road construction and much more. Geofoam is extremely light weight and can withstand harsh conditions.

This unnecessary loss of energy can be damaging to an owner's utility bill. Expanded polystyrene (EPS) is often incorporated below-grade due to its moisture-resistant characteristics. Fortunately, there are many below-grade insulation solutions on the market to aid in the energy efficiency of a structure, such as EPS.
