Insulation Services for a Sustainable Future

Many people assume that two insulation products with identical R-values will perform the same way. This is a significant misconception that could be costing you money and comfort.

Here's the truth: R-value only tells part of the story. While it's measured in controlled laboratory conditions, real-world performance can be dramatically different. Take extreme cold, for instance - when temperatures drop below zero, fiberglass insulation can lose up to 50% of its R-value. In contrast, cellulose insulation actually performs better in these same conditions.

Why such a difference? The R-value test only measures one factor: thermal resistance through conduction. What it doesn't measure is equally important - how well the insulation prevents air movement. Since the primary goal of insulation is to stop heat transfer, this is a crucial oversight.

In real-world conditions, the ability to block air movement often matters more than the rated R-value. This means that two products with the same R-value rating can perform very differently in your home, especially during extreme weather conditions.

Understanding this difference is key to making an informed decision about your home's insulation needs. Want to learn more about which insulation solution would work best for your home? Contact North Country Insulation for a professional assessment.
