These cork sheets are naturally dark (nearly black) in color and although designed for insulation purposes they do have multifunctional uses. The Semi rigid insulation cork sheets possess excellent heat/cold insulation properties they also can simultaneously function as wall/ceiling tiles and tackboards. They are available in several different sizes and thicknesses. Since they are meant primarily for insulation purposes they do initially release a small "burnt cork" smell which will dissipate over time. Also used to reduce vibration. Semi rigid insulation cork sheets boast an R-value of 3.7 per inch.
