EPS (expanded polystyrene) is tailor-made for a variety of applications in construction including, but not limited to, residential and commercial building, roadway and foundation stabilization, and a wide range of other custom solutions. Geofoam blocks, used as ultra-lightweight fill below highways, parking lots and embankments take advantage of EPS’ properties of light weight, easy installation, durability and resistance to rot, mold and mildew. EPS is the most cost-effective insulation material, whose R-value does not decrease with age. When it comes to your next construction project, expect nothing less than perfect. Trust no one other than Plymouth Foam.

Building Solutions Using Expanded Polystyrene
Expanded Polystyrene (EPS) has been long used as a mainstream rigid insulation material, and is highly regarded for its energy efficiency. It is the only architectural insulation material with an R-value that will not decrease with age. Additionally, EPS is lightweight, easy to install, durable, and resistant to rotting, mold and mildew.

New research into EPS has
busted all of the myths and made using this as a building product even more desired. Engineered ESP or sometime known as Architectural EPS, has been proven through various studies to be strong, have a more consistent R-value, be environmentally friendly and green, absorb less and expel more moisture and have better long-term characteristics.

EPS is also the most cost effective rigid insulation in the market. In fact, EPS is the best value by providing the
lowest cost per R-value inch. Don’t just take our word for it, Value Engineering will tell you the cost value just like it saved this contractor 1000’s of dollars on his construction project. Our foam insulation has been saving customers and building owners money compared to other insulation products and have help them save money by reducing their utility cost.

Today, we hear a lot about for the need for sustainability, environmentally friendly and green. Thermal insulation is the single largest factor which influences the energy performance of a building. EPS has been proven to hold its thermal properties longer than any other insulation, even when moisture is present. EPS cell structure is 98% air, which makes it easy to transport and the low weight saves fuel cost during transportation. Not only is the product 100% recyclable but our plant recycles waste and cut off inside the factory and reuses the waste into new products. In fact, EPS is one of the
most recycled plastics in the world.
