To build a structural insulated panel home the first step for homeowners, is to identify a quality builder who has experience with SIP construction. An experienced SIP builder will manage the plan conversion and review process. Find a manufacturer or dealer/distributor to work with. These companies typically handle the plan conversions and engineering services necessary to get the project underway. This is where Xtreme Coastal Builders can assist. We can provide all of the above to make the process smooth and enjoyable.


The construction of a SIP home or commercial building begins with the construction documents. Once the construction documents are in the hands of Xtreme CBS design professional, they are converted to SIP shop drawings that give the dimensions of each individual panel. The shop drawings are reviewed by the builder, engineer, the building owner, and other involved parties. Once the shop drawings are finalized, the SIPs are fabricated and shipped to the jobsite for installation.


What considerations do you need to take into account when building with structural insulated panels vs. conventional framing?
The majority of construction with SIPs is very similar to conventional framing. SIPs accept dimensional lumber and are fastened together using staples, nails or screws. Proper sealing is especially crucial in a SIP structure. All joints need to be sealed with specially designed SIP sealing mastic or low expanding foam sealant, and/or SIP tape.



SIPs may be revolutionizing the structures of buildings but they are not new to construction and design. The earliest concept of structural sandwich panel technology was developed in the 1930s at the Forest Products Laboratory (FPL) in Madison, Wisconsin. FPL engineers proposed that plywood and hardboard sheathing could take a portion of the structural load in wall applications. Their prototype was used to construct test homes that continued to be monitored over thirty years, then disassembled and reexamined. During this time, FPL engineers continued to experiment with new designs and materials.
