Our Services:  Western SIPs strives to be your one stop SIP supplier by providing the services listed below.


    SIP shop drawings need to be reviewed and sealed by a registered professional engineer. Western SIPs has formed relationships with several structural engineers that are knowledgeable in SIPs and are able to review and seal your SIP shop drawings.

Panel Packages:

   Western SIPs only supplies SIP panels manufactured by CNC machinery in order to provide the most precisely cut SIP package possible. In addition to pre-fabricating panels, we also can provide all of the lumber required within the SIPs. This lumber package is shipped with the SIPs and in order to save time on-site, whatever can be pre-installed in the factory is. This package is called a Ready To Assemble (RTA) package. If you are comparing prices with other panel suppliers and you find a huge discrepancy, check for this service first.

Let Western SIPs show you how to do it right!


    A good design is critical to enable a builder to perform their best. Though SIPs can be integrated into almost any design it is a good idea to have an Architect / Designer that has worked with SIPs in the past. At Western SIPs we only work with Architects / Designers that have a thorough background in all aspects of construction which enables them to integrate SIPs into the project in the most efficient manner.


   At Western SIPs we want your project to be a success.  Western SIPs can provide construction services that go beyond the SIP enclosure. Examples include framing, window installation, siding, and finish carpentry to complete the construction process. Our level of experience makes us a leader in the SIP industry.

Project Management:

   Western SIPs will work with you during all stages of your project. If you decide to use Western SIPs your Project Manager will always be available to assist you throughout the course of your project.  We will be there to assist from the initial design through the final walk-through.
