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" organizations.
Oregon SIPS Builders
Maple Brook Engineering
Siletz, Oregon engineering group that designs SIPs
home projects. They look to be fairly exclusive, stating
that they work primarily with repeat clients and referrals,
but they have some good information on their website
and it probably wouldn't hurt to submit a proposed
project to them.
