The R-value of an insulation product is a measure of its thermal resistance or its ability to prevent heat loss through conductive heat flow. R-13 insulation products have a relatively low thermal resistance and are typically used to insulate 2×4 or 2×6 wall studs, as well as the floors and crawl spaces of homes that are located in climatic Zones 1 and 2, as determined by the US Department of Energy. If you’re not certain whether or not an R13 insulation product is right for your construction project, don’t hesitate to reach out to our experts here at Pacific Insulation Supply. Our insulation professionals can help you determine whether you need faced fiberglass insulation batts, unfaced fiberglass insulation batts, or another type of insulation solution.
