HT blanket insulations, both Type 1 and Type 2, may be applied directly to any hot surface. This is normally accomplished by securing through the use of welded studs and nuts or pins and speed washers and then providing a final covering of sheet metal, expanded metal, metal mesh, or cemtentitous mastics. If pins and speed washers are incorporated, you must ensure that the insulation is not compressed under the washer.
