Energy Efficient

Energy-efficient homes built by NW Building Systems are with Structural Insulated Panels (SIP). This innovative material and structural design can reduce your energy bill by up to 50%.

Build Quality

One of the hallmarks of a quality home or commercial building is a tightly-sealed, well-insulated structural shell. Usually, insulation fails because gaps and cavities along the walls or roof allow interior conditioned air to escape while also permitting unconditioned air to infiltrate the structure. The NW BUILDING SIP panel system provides a continuous core of solid expanded polystyrene (EPS) insulation. This means it does not sink like fiber batting or shrink over time like spray foam.

Higher “R” Value

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.
