Describe the end use of the building:
This project, a home renovation using beams and frame from a 100+ year old barn, is the owner's primary residence.

How did SIP construction help you get this job?
The owner was sold on the additional strength SIPs provide, the speed of assembly and the energy efficiency.

SIP wall thickness and core material:
6" walls with EPS insulating core

SIP roof thickness and core material:
12" roof with EPS insulating core

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
Once the frame was squared up, the SIPs added the structural strength. They were able to install all the panels for this structure in less than one week.

Describe any innovative design elements or structural engineering involved:
The entire frame was excavated and lifted; new stem walls were put into place, and the structure was set back down, squared, and wrapped in SIPs.

Describe the HVAC system used on the project:
Mr. Alvin installed in-floor heat with an LP gas boiler. A mini-split was installed for cooling the home. A heat pump was also installed.

Describe any other energy-saving materials used in the building envelope other than SIPs. List U-values of windows used and the U or R-value of any insulation materials. 
The home is clad with Marvin Triple Pane windows.

Any additional comments on the project:
The owner, 73 year old Jon Alvin, is a retired commercial contractor. He stated, "I built tip-up concrete buildings all over the Country, and these SIP Panels impressed me more every day I worked with them. And, even more, now that I live inside of them."

This reclaimed oak-timber barn had timbers with "by the Long Family, 1885-1890" carved into the wood. These oak trees would have been well over 125-150 years old when harvested, aging the timber to 250-300 years.

The original ceiling was saved and used in the current home. Interior and exterior trim was the batten strips from the barn. He re-purposed other timbers into furnishings for the home.

The owner was his own General Contractor and was very hands-on in the construction of this reclaimed barn/home.

While a HERs Test was done, the results are not yet available
