Armaflex insulation is a flexible elastomeric thermal insulation supplied as unslit tubing. The expanded closed cell structure of Armaflex insulation makes it an efficient insulation. The closed cell structure of Armaflex insulation effectively retard the flow of moisture vapor and Armaflex is considered a low transmittance vapor retarder. Additional vapor retarder protection may be necessary when installed on very low temperature piping or where exposed to continually high humidity conditions. It also efficiently reduces heat flow for hot water plumbing and liquid heating and dual temperature piping. For use on cold pipes, Armaflex insulation thicknesses have been calculated to control condensation on the insulation outer surfaces, as shown in the table of thickness recommendations. The insulation is designed for installation above ground. Indoors, no protective finish is required but may be desirable. Outdoors, a weather resistant protective finish is to be applied.
