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 emergency shelter survives some of the world’s highest snow loads

Net-Zero has supplied and constructed a two-story 1470 square foot emergency shelter for Regional Power, the owner/operator of the 31 megawatt Long Lake run-of-the-river hydro generation project.
