Use Caution With SIP Construction!
Structural insulated panels (SIP) are a prefabricated assembly of rigid foam insulation sandwiched between layers of structural boards, often oriented-strand board (OSB). These panels are used for walls, floors and roofs for homes in place of “conventional” stick-built construction.
While SIPs have been around for a long time, they are currently gaining a lot of attention and many home builders are making SIP panels a part of there regular construction or at least offer it as an option.
As with most anything, SIP construction has several pros and cons. On the pro side, they are very energy efficient, mechanically sound and quick to construct. On the other side, they are normally more expensive than conventional framing and the consequences of poor fabrication and/or defective installation can be extremely difficult to correct.
Caution needs to be used when deciding on SIP construction. The fabricators and installers must be properly trained to avoid severe problems. People involved with conventional, stick-built home construction are not qualified to perform SIP construction unless they receive the proper training. In addition, the cutting of holes in SIP panels (for skylights or other items) must be carefully reviewed to avoid compromising panel integrity.
