Rigid fiber or fibrous board insulation consists of either fiberglass or mineral wool material and is primarily used for insulating air ducts in homes. It is also used when there's a need for insulation that can withstand high temperatures. These products come in a range of thicknesses from 1 inch to 2.5 inches, and provide an R-value of about R-4 per inch of thickness.

Installation in air ducts can be done by RBC Insulation contractor. On exterior duct surfaces, we can install the insulation by impaling it on weld pins and securing with speed clips or washers. We can also use special weld pins with integral-cupped head washers. Unfaced boards can then be finished with reinforced insulating cement, canvas, or weatherproof mastic. Faced boards can be installed in the same way, and the joints between boards sealed with pressure-sensitive tape or glass fabric and mastic.
