Product Features
AP ARMAFLEX®, the world's most recognized brand of closed-cell foam insulation, provides superior protection against thermal losses, condensation and moisture accumulation that leads to mold. It is the ideal choice for insulating mechanical piping systems. Now offering Larger 8 and 10 in IDs for ease of installation on larger pipe sizes. Schools, hospitals, government institutions and commercial spaces of all types value the long-term performance and peace of mind that AP ARMAFLEX® lends to mechanical piping systems. Its moisture-resistant characteristics make it especially valuable on chilled-water and refrigeration piping where condensation might otherwise soak through fibrous types of insulations, significantly degrading their thermal performance, leaving them susceptible to fungal growth and ultimately shortening their lifecycle. Moisture-resistant AP ARMAFLEX®, however, maintains its physical and thermal integrity for the life of the mechanical system.
