Homes and buildings need insulation to control inside temperatures. Are you getting the best value for your project? Here's a look at how R-Value affects what you pick.

Mineral Wool Insulation R-Value Mineral stone wool insulation batts are slightly better insulators than the off-the-shelf fiberglass batts sold at most lumberyards and home centers.

A: R-value refers to the level of resistance to heat flow that insulation — from fiberglass attic insulation to pipe wrap — provides. Heat, of course, tends to radiate outward and upward, and ...

R-value is the standard measurement when you compare the insulation ratings of various materials. The R-value indicates the resistance to heat transfer of a given type of insulation.

R-values are given per inch, so the lower the R-value per inch, the thicker the layer of insulation you need. Attics and cathedral ceilings require the most insulation, walls and floors the least.

Despite this trend, it has been shown that dynamic insulation systems, which offer variable thermal resistance, have been shown to decrease energy consumption by adapting the envelope’s R-value ...

Talk about insulation means talk about R-values. Insulation material has pockets of trapped air that prevent heat from penetrating it. R-value measures how well the material resists that heat ...
