Micro-Lok® HP E3 Compression Pack® is an Economical, Efficient and Environmentally friendly way to package our Micro-Lok® HP Plain Pipe insulation. Designed to better protect the product inside, Micro-Lok® HP E3 Compression Pack minimizes damage during transport. Because the pack forms cube-shaped units, product can be shipped and stored more efficiently. Once opened, pipe sections bounce back into their cylindrical form and retain their original insulation strength. Continuing JM's dedication to sustainability, the label and packaging is now 100% recyclable, resulting in less job site waste.
