What are Structural Insulated Panels?
Structural Insulated Panels (SIPs)- a building material that consists of
panels made from a thick layer of foam (polystyrene or polyurethane)
sandwiched between two layers of Oriented Strand Board (OSB).
Structural panels offer very effective insulating qualities, rapid installation,
and consistent quality (minimizing waste). The use of OSB or waferboard
for facings is considered a positive use of wood resources. In addition,
less wood is wasted at the construction site than stick built homes making
structural insulated panels favorable materials to "green building"
