Superior R-Values Lead to Greater Comfort

Jan 12, 2017 

When the weather is cold the thermal comfort of our homes is important. Our homes are built with different materials, with each material having its own r-value.

R-value is a material's resistance to heat flow, and a higher r-value means that it will conduct less heat. The flip side is that the inside of a wall built with materials with a higher R-Value will feel warmer on the cold winter day. A warmer wall equates to greater comfort.

The important thing about r-values is that you must account for the r-value for all of the components in a wall, the average r-value, and not just the nominal r-value of the insulation. The average r-value is also referred to as effective r-value. When comparing different wall systems (i.e. SIPs, stick frames, advanced stick framed) it's important to compare effective r-values and not the nominal r-values of the insulation. SIP walls have an advantage over most other wall systems because of their continuous insulation leads to higher effective r-value for the same thickness of wall. For example a 6" SIP wall has a 42% greater r-value as compared to a 2"x6" wall with batt insulation. Combine this with their greater ease of construction as compared to a double stud wall construction and the advantages add up more.

Energy-Efficient Chalet on Hudson Bay Mountain Built with SIPs

When Jodie and Rob Blackburn decided to build a private chalet on Hudson Bay Mountain, they knew a conventional stick-frame construction was not going to be the most efficient building for their needs. 

“I began to research energy efficiency and affordability and your companies’ product quickly became the front-runner,” says Rob. “We chose Net-Zero Structure’s structural insulated panels (SIPs) for many reasons including ease and speed of erection as well as cost and availability.”
