SIPs consist of an inner core of Expanded Polystyrene (EPS) which has been laminated between two structural facers of Oriented Strand Board (OSB) using a structural adhesive.
This engineered system provides an extremely strong building panel that does not require any additional framing for support. Large Pre-Fabricated SIP panels make the Framing Process much faster than any other framing method and enable a more airtight, well insulated building for high Energy Efficiency.
SIPs are available in a variety of thicknesses and sizes ranging from 2 to 12 inches thick and sizes from the standard 4′ x 8′ to 8′ x 24′. SIP panels generally weigh less than 4 pounds per square foot, making them light enough to install by hand in the case of wall panels. A crane or tele-handler is used for larger roof panels or for lifting bundles of panels on the job site.
Once the SIPs are installed, you can apply virtually any finish to polish off the exterior — stucco, stone, Hardi Board, brick or clapboard.
