Building Insulation Materials - Cotton Batts (Blue Jean)

Cotton Batts (Blue Jean)

Cotton insulation is increasing in popularity as an environmentally preferable option for insulation. It has an R-value of around 3.7 (RSI-0.65), equivalent to the median value for fiberglass batts. The cotton is primarily recycled industrial scrap, providing a sustainability benefit. The batts do not use the toxic formaldehyde backing found in fiberglass, and the manufacture is nowhere near as energy intensive as the mining and production process required for fiberglass. Boric acid is used as a flame retardant. A small quantity of polyolefin is melted as an adhesive to bind the product together (and is preferable to formaldehyde adhesives). Installation is similar to fiberglass, without the need for a respirator but requiring some additional time to cut the material. As with any batt insulation, proper installation is important to ensure high energy efficiency.

Famous quotes containing the word cotton:

    It is remarkable with what pure satisfaction the traveler in these woods will reach his camping-ground on the eve of a tempestuous night like this, as if he had got to his inn, and, rolling himself in his blanket, stretch himself on his six-feet-by-two bed of dripping fir twigs, with a thin sheet of cotton for roof, snug as a meadow-mouse in its nest.
    Henry David Thoreau (1817–1862)
