AP Armaflex TubeThermal Insulation Solutions for Energy Savings

AP ArmaFlex®, the original elastomeric closed-cell foam insulation, has been the chosen fiber-free mechanical insulation since its introduction in 1954. Superior condensation control and consistent thermal performance have made ArmaFlex the preferred insulating material for pipes and ductwork. Its efficient installation and superior performance has won it favor among contractors, engineers and end-users who understand its long-lasting value.  

The closed-cell foam structure of ArmaFlex prevents moisture from wicking or transferring from the surface of the insulation to the surface of the pipe or duct. This means that water won’t be trapped next to the metal, AP Coilflex Duct Linercausing corrosion and eventual damage to the system. Because of its non-permeable, closed-cell foam structure, no additional vapor retarder is required to protect ArmaFlex insulation, saving the installer time and cladding material cost. Unlike fibrous insulation, which loses R-value and must be replaced when it becomes wet, ArmaFlex performance stays the same, regardless of surface punctures or exposure to moisture.
