Whenever we pick up a magazine these days, it’s common to see articles entitled “Seven Steps to a Green Home,” “Affordable Solar Energy” or “Create the Perfect Home with Alternative Building Systems.” We get a little chuckle when we read those articles because we continue to be reminded that those seven steps are not necessarily simple or affordable, and the definition of “perfect” encompasses a range as broad as the Rockies. However, when it came time to insulate the roof of our house, the nexus of simplicity, affordability and perfection seemed to land very neatly on our doorstep.
When we left the house in November, 16-inch scissor trusses had been set in place on top of the interior sheathing. Off and on throughout December, subcontractor Kirk Chappel and his employee, Brian Briel, added the exterior roof sheathing and built the east and west gable end walls. Our next task was to fill the cavity between the interior and exterior roof sheathing with insulation.
Wayne, our architect, designed an unvented roof that would have an approximate r-value of 60. To achieve this, we would use cellulose insulation purchased from Mountain Fiber Insulation in Hyrum, Utah. You might ask why we would bring insulation all the way from Cache Valley to Torrey when we could have, perhaps more easily, purchased it from Loa Builders. That is a fair question especially considering our determination to use local products and employ local people.
Scott arrived in Torrey on January 11, one day prior to the semitruck delivery of 484 bales of insulation. With the help of Kirk and Brian, in less than four days, that insulation had disappeared inside our roof, and Scott was back in Logan the following Sunday. Here’s what happened, step by step.
Next week, Tyler Torgerson and his crew will install RMax Thermasheath as the next layer on the roof. This is a rigid foam plastic thermal insulation board composed of closed cell, polyisocyanurate foam which is bonded to reinforced aluminum foil facers. Our ASC standing seam metal goes next. Then, and finally, Phillip Winters will be able to install our solar heat exchange panels...all just in time to meet the deadline for our alternative energy grant.
