  5. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    Loose-fill insulation comes in loose fibers or pellets and should be blown into a space. Rigid foam is more expensive than fiber, but generally has a higher R-value per unit of thickness. Foam-in-place insulation can be blown into small areas to control air leaks, like those around windows, or can be used to insulate an entire house. [33]
