What is an EPS block?

EPS geofoam is a lightweight foam plastic that’s manufactured into blocks and commonly used as a structural geofoam backfill. EPS geofoam has a unit density that can be roughly as low as one pound per square foot. It’s an extremely lightweight alternative to soil that’s nearly 100 times lighter than most soils.

What is the difference between Styrofoam and EPS?

As we said, Styrofoam™ is a Dow trade, blue in color, and is an extruded polystyrene (XPS) foam made for thermal insulation, construction and craft applications. EPS is an expanded polystyrene available in various densities for insulation, construction and craft applications and so much more.

What is EPS foam used for?

Expanded PolyStyrene (EPS) is a white foam plastic material produced from solid beads of polystyrene. It is primarily used for packaging, insulation, etc. It is a closed-cell, rigid foam material produced from: Styrene – which forms the cellular structure.

How much does a foam block cost?

Currently, the purchase price of a regular 16” x 48” styrofoam ICF block is in the $24-$28 range, depending on what region/country it is purchased in. This translates to about $4.50 – $5.50 per SF of wall area.

Is EPS foam fire resistant?

Untreated EPS foam burns at 650° to 700°F with a flame source. It won’t continue burning on its own until 840° to 930°F is reached. Wood burns at 480° to 660°F.

Is EPS foam closed cell?

Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material.

Is ICF cheaper than wood?

Before rising lumber costs and construction labor shortages, several studies determined that ICF construction would add about 3 to 5 percent to the purchase price of a typical wood-frame home, which amounts to $9,000 to $15.000 for a new home valued at $300,000.

At what temperature does EPS melt?

212° F
When burning, expanded polystyrene behaves like other hydrocarbons such as wood, paper, etc. If EPS is exposed to temperatures above 212° F (100° C), it begins to soften, to contract and finally to melt.

Is EPS foam combustible?

FLAMMABILITY AND TOXICITY As with many other construction materials, EPS is flammable. In all cases, this is only relevant if EPS is evaluated as an exposed insulating material.

What is the best insulation board?

PIR insulation boards. PIR boards (polyisocyanurate insulation) have a wide applicability and are perfectly suited to insulate a flat roof or a cavity wall.

Where to buy block foam?

Chances are, if you are on the east coast between Virginia and Maine you may be ordering your giant foam sculpting block from Insulation Company of America in Allentown, PA just north of Philadelphia.

What is expanded polystyrene (EPS) foam used for?

What is EPS board insulation?

Expanded Polystyrene Insulation Board is affixed to the substrate and creates a layer of continuous insulation. EPS (Expanded Polystyrene) is a key component in most of Dryvit’s Outsulation® systems.
