“Major power outage in North Idaho. We had no heating for 9 hours yesterday - It was 50 MPH wind all day, partly sunny, 41 degrees. Guess how the temperature in our Faswall building changed?  House did not change, garage dropped from 65 to 63. We opened the door to drive the car out and also opened the person door several times.
Needless to say:     WE LOVE OUR FASWALL STRUCTURE!!!
Also, with the 50 MPH winds, gusting to 70 MPH, our building was stable and quiet inside. We were able to sleep, work, etc.”

Home Owners and Builders

“We did a lot of research on various green building systems but settled on Faswall. Not only did it seem like the “greenest” technology, but the ease of building compared to other systems seemed like a good choice for an owner/builder. What we didn’t expect, but were totally delighted with, was how knowledgable and helpful the people at Faswall were. We couldn’t have done it without you!”

-Ted and Donna Havecheck
