How did SIP construction help you get this job?
We are finding the SIP construction to be superior to any home we have owned. The ease of erecting the SIPs proved helpful when the construction of our home entered the winter months. The house is well built and gives one the feeling of being in a very quiet, sturdy structure. Our new home is in a climate with moderately warm summers and very cold winters. In summer, it remains cool even on a hot day. On a cold winter day, the home retains heat and is very comfortable. We anticipate the annual heating costs will be lower than if we had used traditional construction.

SIP wall thickness and core material:
6" Nepor

SIP roof thickness and core material:
10" Nepor

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
Saved time and labor and due to location of the house being in the woods.
