Durable, easy-to-install, closed cell pipe insulation for plumbing and refrigeration.

Armacell is pleased to announce new and improved, AP Armaflex® Black LapSeal™. It’s the original flexible elastomeric pipe insulation with a new and improved lap seal for greater seam security and increased protection against condensation, mold and energy loss. Installers who already like the quick application of self-seal and lap seal Armaflex will appreciate the enhancements to our newest pipe insulation innovation, available for the first time in a wider range of popular small wall sizes.

Black LapSeal’s new angle-cut seam has up to 40% more surface area on the self-sealing connection points compared to other similar products in the marketplace. Other new features include an improved lap seal closure system, with a wider release tab on the lap tape which can be easily removed for installation. For added security, the low-profile lap seal ensures the longitudinal seam stays closed and looks neat. It’s the ideal solution for speeding up install times or making hard-to-reach installation areas easier to accommodate.

Like all AP Armaflex products, Black LapSeal’s closed cell structure means that it will not wick moisture and needs no additional water vapor retarder. The flexible, but durable, fiber-free elastomeric foam resists punctures and won’t crack or flake over time. When installed and maintained properly, Black LapSeal insulation should last the life of the mechanical system. On outdoor applications, Black LapSeal should be installed with a water-resistant jacketing or painted with Armaflex® WB Finish to protect it from UV degradation.

For condensation control on chilled water or refrigeration lines, there’s no equal to elastomeric foam insulation. This easy-to-install flexible pipe insulation keeps cold pipes from sweating, preventing expensive damage to the equipment or its surrounding environment. When the system stays dry, the chance of mold developing is drastically reduced. And for further peace of mind, AP Armaflex Black LapSeal is made with Microban® antimicrobial technology to prevent the growth of mold or mildew in the insulation.
