A recent survey conducted by the Structural Insulated Panel Association, SIPA, identified 78 companies in the US and Canada that manufactured SIPs in 2007, for a total of 69 million sqft of sandwich panels… This is a 4.5% increase from the previous year.
The survey mentions that although residential SIP construction has slowed through the housing decline, the use of SIP sandwich panels has increased greatly in commercial construction.
