What is EPS?


Expanded polystyrene is an organic material manufactured from crude oil by-products. The manufacturing process consists of the expansion of polystyrene beads in a mould, which contains an expanding agent, pentane. When submitted to water vapour, the beads expand until they completely fill the mould. During the expansion process, the expanding agent dissipates and air is introduced to the cell structure. The final product is a rigid insulation comprised of a closed cell structure consisting of 98% air.

What is EPS used for?

EPS is widely used in packaging applications for the transport of produce, seafood and fragile items. EPS is also becoming a popular material for use in building and construction applications. Examples include geofoam, a light-weight void filler, insulated panel systems, wall cladding systems and concrete slab footing systems known as waffle pods.

What are the benefits of using EPS?

EPS is widely used in many everyday applications where its light weight, strength, durability, thermal insulation and shock absorption characteristics provide superior benefits over other materials. These characteristics, combined with its versatility, performance and cost effectiveness have made EPS a packaging and building material of choice for over 50 years.

Why use EPS?

Expanded polystyrene demonstrates the properties of stability, durability and moisture resistance. Its low price, versatility, easy installation and insulation value/price ratio make it an insulation of choice for architects, estimators and contractors.

Is EPS harmful to my health?

No, EPS is not harmful to health. Styrene is naturally occurring in foods such as strawberries, peaches, cinnamon, beef and coffee. In 2002, an international panel of independent experts selected by the Harvard Center for Risk Analysis reported that the very low levels of styrene present in foods—whether naturally occurring or from polystyrene food service products—does not represent a concern to human health.

Is EPS harmful to the environment?

EPS is inert, non-toxic and emits no ozone-damaging gas.This material is recyclable and reusable and retains its insulating value over the long term. The use of EPS insulation products significantly reduces the energy requirements for heating and cooling in buildings. This results in lowered carbon dioxide emissions giving an overall positive contribution to the environment.

Is EPS flammable?

EPS will melt but is self extinguishing and does not support a flame.

Can EPS be recycled?

Expanded Polystyrene (EPS) is recyclable and is being recycled by businesses and consumers across the world. The EPS industry developed collection infrastructures to support global recycling efforts. EPS can be recycled into a variety of new products.

Why use light gauge steel?

Residential steel framing members are cost-effective, lightweight, easy-to-handle, and manufactured in conditions that allow strict quality control. When designed properly, the result is solid, non-combustible, and durable. Because steel can be pre-cut to desired lengths and is a stable material, you don’t need to sort out defective pieces and can erect a frame faster. Also, steel scrap has value and can be recycled.

Doesn’t a tight structure mean mold?

Having a tight structure allows you to dictate what air gets in and out of the structure. By employing accurate HVAC sizing, humidity controls and measured exchanges of fresh air your indoor air quality is greatly improved.

How are electrical, plumbing and data lines run through a solid wall?

The Solid Green Panel accommodates all utilities through patented, standardized access points within the panel.

What does R-value signify?

R-value is a measure of thermal resistance (RSI in the metric system), indicating the performance of an insulation material. The higher the R or RSI value, the more the material is resistant to heat transfer and the more it constitutes a good insulation. Expanded polystyrene’s R-value is stable and permanent.

Is the Solid Green Panel a SIPs panel?

No, the Solid Green Panel is a rigid insulating panel introduced into an engineered light gauge steel framed structure.


How much more does the Solid Green Systems building system cost than wood framing?

It will actually cost less if you follow the recommendations and guidelines for the project plan your builder or we will propose. By using best practices including energy monitoring, efficient construction methods, and overall evaluation of the total cost to build, own, and operate you should gain a higher appraised value, much lower energy bills,and more.

Working with Solid Green Systems

How much more complicated is the Solid Green Systems building system?

We use a design/build process that incorporates energy modeling, advanced framing, manufacturing logistics for product delivery, and more. Your builder and you will find that the process is actually more pleasant, with more easily understood options for your home, and a faster build time. Overall, this planning and implementation process makes things easier for you.
