Insul-Tacks permanently fasten insulation to prepainted metal surfaces without marking the finished side of the metal. Zinc-plated and heat treated, they do not degrade in extreme temperatures or corrosive environments. Insul-Tacks are manufactured with a precisely formed conical point that is driven through the insulation and into the sheet metal with controlled impact. The point penetrates no more than 0.015 in. and grips into the surface of the sheet metal. Insulation is held in place with a 1-in. retaining cap. Each fastener holds about 40 lbs. and they are applied with automatic equipment and no adhesive overspray and no need for fume hoods or for special adhesive-fume ventilation.
