Delta®-Board is manufactured from mineral wool bonded together with a high temperature binder. It is a highly efficient insulation recommended for commercial and industrial applications operating between -20F (-29C) and 1200F (649C). It is available in densities ranging from 3lb/cubic foot to 12lb/cubic foot. There is a wide range of applications for Delta-Board including use on ovens, ducts, boilers, vessels, tanks, and equipment. Because of its light weight, large sizes can be applied quickly and generally attached by means of weld pins and clips, strapping, or wire mesh, and then finished with either metal, plastic lagging, or reinforced mastic.
