EH Systems is a manufacturer and distributor of Structural Insulated Panels (SIPs) that provide builders with a unique system to construct residential and commercial buildings that save time and money. SIPs are layers of expanded polystyrene sandwiched between oriented strand board (OSB) that make buildings stronger, more durable and more energy efficient than conventional "stick-built" construction and are framed in less time. Builders who use our unique system can save homeowners more than 50 percent on their heating and cooling bills while providing a stronger, cleaner living environment.
