Not only is our insulation capable of meeting, or exceeding the recommended R-values (thermal resistance) for every climate, our whole-wall, and roof SIP systems reduce the number of thermal bridges. A thermal bridge occurs every place within a wall where the insulation is interrupted. In a standard home, for example, there are 2″ x 6″ studs located every 16-inches. And, each of these breaks in the main insulation creates an opportunity for energy to easily transfer through the wall because wood offers less resistance than insulation. Insulspan EPS SIP walls and roofs have far fewer thermal breaks. The result is a higher R-value for the whole-wall as compared to a stick-framed wall.
