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 ...

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.

R-Value: The ability of the material to resist heat flow. This is the insulation’s thermal resistance. The higher the R-Value, the more insulation it will provide.

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 ...

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.

The higher the R factor -- for instance, R-19 versus R-30 -- the better the insulation is at preventing thermal loss or gain. The R-value depends on the type of insulating material used and its ...

For most types of insulation, the R-value is determined by the thickness of the material. Fiberglass insulation 3 1/2 -inches thick might have an R-value of R-11, while the same material 6 inches ...

When you talk with insulation contractors, make sure they quote the R-value of the insulation you are getting. Particularly with blown-in, loose-fill insulation, the density can be too low.
