Blanket rock-wool insulation shows excellent thermal and acoustical insulating properties. Normally a wire mesh is attached to blanket products, distinguishing such products from other types of rock-wool insulations. Blanket rock-wool insulations are very dense and resin free which this matter increases their thermal resistance up to 8000C. The fibers are actually woven in blanket products which increases the products bending and tensile strength. Blankets are offered with craft-paper covers, aluminum foils, and fire resistance textile or without jacketing. The blanket products are produced according to ASTM C592 and are available with single side or double side wire meshes.
