WHAT IS POLYSTYRENE? We benefit daily from products manufactured from polystyrene plastic, including thermal insulation for construction applications and cushion packaging for industrial and consumer applications. There are two common types of polystyrene foam, extruded polystyrene (popularly known by its Dow trademark Styrofoam®) and expanded polystyrene (EPS). Most food service applications including meat trays, egg cartons, hamburger clam shells, foam plates and trays are extruded polystyrene. However the common coffee cup is expanded polystyrene as is almost all industrial cushion packaging. This is the cellular white molded foam that is used to package televisions, stereos, computers, and delicate electronic equipment and other fragile industrial and consumer products. Both expanded polystyrene (EPS) and extruded polystyrene are used extensively as thermal insulation in industrial, commercial and residential construction. Back to Top 2. Q. DOES EPS FOAM CONTAIN CHLOROFLUOROCARBONS (CFCs) OR HCFCs? No. EPS foam products have never been manufactured with CFCs. The expansion agent for EPS material is pentane. Back to Top 3. Q. WHAT ARE CFCs? WHAT IS THEIR IMPACT ON THE OZONE LAYER? Fully halogenated chlorofluorocarbon (CFCs) are a family of chemical compounds used mainly as refrigerants for freezers, refrigerators and air-conditioning units, and as industrial cleansing solvents primarily in the high-tech industry. CFCs are also used as an expansion agent in the manufacture of isocyanurate thermal insulation, and some extruded polystyrene foam used for thermal insulation, and some extruded polystyrene foam used for thermal insulation products, and food service containers. When released into the atmosphere, CFCs rise to the stratosphere where they break down and release chlorine. The chlorine then acts to reduce the stratospheric ozone layer, causing an increase in the amount of harmful ultraviolet radiation reaching the earth. Back to Top 4. Q. IS EPS FOAM RECYCLABLE? Yes. Indeed, all plastics can be reclaimed for reuse. Recycling is a way to reduce the amount of trash that needs disposal, and to conserve valuable raw materials. The plastics industry is working actively to develop recycling programs that are both efficient and economical. Back to Top 5. Q. IS EPS FOAM BIODEGRADABLE? Since EPS foam does not biodegrade, it is benign to the environment and provides a stable fill material similar to earth, rock or concrete. This allows for safe landfill reclamation for parks, schools, ball fields, golf courses, and other public or greenbelt utilization. Our goal should be to limit materials from getting to the landfill through source reduction, aggressive recycling, and other environmentally sound waste management programs. Back to Top 6. Q.WHAT ARE THE BENEFITS OF EPS FOAM THERMAL INSULATION PRODUCTS AND INDUSTRIAL CUSHION PACKAGING? EPS foam products whether used for insulation or packaging are lightweight, versatile, sanitary, energy efficient, and most of all cost effective. The manufacture of EPS foam uses less energy than that used in the manufacture of paper based alternatives. According to The Midwest Research Institute study on special packaging applications, the total energy requirements to make plastic containers (including both processing and materials energy) were lower than or equal to the energy consumed to make competing materials. Further, EPS's physical properties allow for almost universal application, Information regarding the suitability of EPS for a specific application is available upon request. Back to Top 7. Q. DOES EPS FOAM GIVE OFF TOXIC EMISSIONS WHEN INCINERATED? No. EPS foam's chemical makeup consists of carbon and hydrogen. When completely combusted it gives off water vapor, carbon dioxide and trace levels of ash, the same as paper. Back to Top 8. Q. IS EPS CONSIDERED TOXIC? The simple chemical make up of EPS is carbon, hydrogen and oxygen; elements found in wood and other organic materials. Back to Top 9. Q. DOES EPS FOAM CONTAIN FORMALDEYDE? No. Back to Top 10. Q. IS MOLDED EPS THE SAME AS EXTRUDED? No, extruded polystyrene (often in colors such as pink, blue or green) uses a different blowing agent and a different manufacturing process. White molded EPS, unlike extruded, is available in many different densities and thicknesses. EPS insulation systems dramatically reduce energy consumption and its resultant pollution. Back to Top 11: IS VITRUVIAN A DIRECT REPLACEMENT FOR TRADITIONAL CONSTRUCTION METHODS? Vitruvian replaces wood, block, steel and often even concrete. Tools used for assembly are essentially the same as used by traditional 'framer'. Because the steel stud 'tubes' are nested in the EPS, nails can be driven similar to working with wood. Vitruvian panels weigh 1/2 that of wood frame, yet are nearly twice as strong. Back to Top 12: WHAT IS THE COST OF VITRUVIAN? Vitruvian will essentially cost about the same as traditional wood frame. It will cost about 1/2 to 2/3rd's ICF's. Back to Top |
