From these values we can calculate that the equivalent insulating thickness of concrete. It will most likely be a fiberglass batt, so multiply the thickness in inches by 3. May 18, 2017 · The R-value from fiberglass insulation represents the resistance to heat transfer through the material by all three heat transfer modes: conduction, convection, and radiation. When insulation is fluffed, air passes more easily through it. For example, your roof insulation might have an R-value of 20 but combined with the batts and other materials, your roof's R-value might only be 15 or 10. Multiple thicknesses or layers can be combined in a double layer system to achieve high R-values. Johns Manville Formaldehyde-free™ FSK-25 thermal and acoustical fiberglass insulation is available in R-Values up to R-38 and is offered in precut batts to fit standard wall cavities. However, we rarely see a home with batt insulation that doesn't fall short. There are other factors to consider.

Find wet spray systems and spray foam equipment here, as well as loose fill, dense pack insulation and wall blow in insulation. 3 inches of thickness to reach R-38. Skip to the end of the images gallery. R-value denotes resistance to heat flow. Your home's age—If your home is more than 10 year old, you likely need more insulation.
