Structural Insulated Panels ( SIPs )

Serving California, Oregon and Washington with quality SIPs ( Structural Insulated Panels ) providing builders and homeowners a faster, cleaner, greener way to build. The SIP structure is completed to the dried in stage faster than standard framing thus reducing some of the construction costs.

Structural Insulated Panels (SIPs) have been produced for over 30 years. With the OSB industry maturing and the availability of single panels in sizes up to 96” X 288”, SIPs have been steadily gaining a larger share of the construction material market.

SIPs are a panelized construction system generally used for walls and roofs and at times floor systems. The panels are usually made from 7/16” Oriented Strand Board (OSB) face and back with expanded polystyrene (EPS) foam core. Think of a foam coffee cup. The SIP panels are sized to match standard 2” framing materials which are often used as splines to connect the SIP panels together and provide additional support at the openings for doors and windows. Panels range in thickness from 4-1/2” to 12-1/4”. The maximum single panel size is 96” X 288”. The OSB face and back may be ordered in heavier thickness as required by the engineers or contractors to meet special site specific loading requirements such as solar panels.

SIPs go a long way toward meeting the goals of Sustainable Building practices, Green Building and minimizing the environmental impact through:

• Face & Back materials from rapidly renewable wood species.
• EPS does not contain CFCs, HFCs or HCFCs.
• SIP construction minimizes standard framing lumber.
• All components of the SIP panel are recyclable
• Jobsite waste kept to a minimum due to factory fabrication.
• Long term energy savings through building efficiency.
• Superior insulating qualities.
