Foam insulation, EPS insulation, construction insulation

This is a broad term that covers many EPS products. Because EPS is light yet durable, it is often used to insulate foundations, roofs and perimeters.

I recommend: PermaTherm makes a line of EPS insulation products. It outlines the benefits of EPS, and has application tips and diagrams that show where the insulation goes.

Shape mold or custom mold

Custom molding is a way to make EPS packaging that will fit your product like a glove. This way, it will stay snug inside its box and take the occasional bump or rattle without missing a beat. Best of all, you can choose the density and flexibility of the packaging, depending on how you want it to transfer impact.

I recommend: ACH Foam Technologies shape molds EPS to the needs of its clients.

Concrete forms

Concrete forms can be made from EPS blocks that come in different shapes and widths to accommodate steel beams and other structural elements. The product can form to design elements as varied as corners, columns and brick ledges.

I recommend: Quad-Lock makes EPS concrete forms that also insulate the building.

Exterior insulation and finish systems (EIFS)

Rather than forming a concrete mold, EIFS is actually the design element. With computer technology, manufacturers can cut EPS blocks to fit the architect's precise specs. With the right styling, EPS can become a molding or arch. Finishing options can give it the appearance brick or stone.

I recommend: Georgia Foam sells many EIFS products.

Cold storage applications, temperature-control applications

EPS keeps produce from wilting due to extreme heat in transit. The foam also absorbs no moisture, so none is wicked away from the product. It also has shipping applications for nonperishable products that are nonetheless sensitive to temperature swings.

I recommend: Agri-Cel makes EPS shipping products for grapes.

Geofoam

Geofoam is EPS foam that has applications in civil engineering, because it can stabilize a slope or create a retaining wall, among other things.

I recommend: Universal Foam Products sells Geofoam blocks, pre-cut to order.
