Insulation R-value ratings can vary based on the type, thickness, and density of the insulation material. For home improvement work, standard insulation R-values range from R-10 to R-60, depending ...

The R-value for insulation is a way to measure how much resistance the insulation has to heat flow. The higher the R-value, the more the resistance and the better the material is at insulating a home.

The kind of insulation used in the construction business – that pink fiberglass stuff that normally is used in attics and walls- is well known. These insulations, mostly fiberglass, are provided with ...

Typical R-value: R-3.2 to R-7.5 per inch of thickness. Where commonly used: Inside unfinished wall cavities, attics, and basements, and as continuous insulation on a house’s exterior.

Understanding R-Values for Roof Insulation The R-Value is a way to gauge how effectively insulation blocks the flow of heat through it, which can keep heat inside your home on cold days and ...

In South Georgia, Energy.gov recommends insulation with an R-Value of 30-60 for attics, 22-38 for cathedral ceilings, 13-15 for cavity (room walls), and 13 for floor insulation.

Your home's R-value score will guide you toward the type of insulation you need. In general, an attic's R-value should be between R-30 and R-49. In particularly cold climates, you might go up to R-60.

Foam insulation has the advantage of sealing, as well as insulating, and has the highest R-value, 5.1 per inch, of all the insulating products. However, it is also the most expensive.

Batt and poly insulation are also good choices that offer R-values of around 3-4 per inch. Lastly, they highlight that the R-value of fiberglass can vary depending on the density of the material.

Geek Alert: The ability of insulation to resist the flow of heat from one side (your attic) to the other (your living space) can be measured in terms of R-value. R value is defined as ft 2 x ° F ...
