How did SIP construction help you get this job?
As a spec home builder, I chose to use SIP panels in the construction of this house and ADU to help achieve Net Zero status.

SIP wall thickness and core material: 6"

SIP roof thickness and core material: 6"

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
This was my first project utilizing SIP construction. I knew going into the project that there would be a learning curve on this first home. Even with the lack of experience with the product, I still feel that our labor costs were the same if not less than traditional framing. Going forward, I truly believe that SIP construction will save labor costs as well as help me achieve Net Zero certifications, which is my goal. Another major benefit to using SIP construction is the minimal material waste compared to stick framing. This was of great importance to me.
