AK Flex the original elastomeric closed-cell foam insulation, has been the chosen fiber-free mechanical insulation since 1950s. Superior condensation control and consistent thermal performance have made AK Flex the preferred insulating material for pipes and ductwork. Its long-lasting installation and performance have won it favor among engineers, contractors and end-users who understand its long-lasting value.
For insulation applications that require additional jacketing, such as exterior insulation applications where UV rays and weather exposure are a problem, Akawell’s Coverwell is designed with a protective laminated cladding already built in. No need to apply a separate protective metal jacket! Akawell’s Coverwell built-in cladding also increases the overall lifespan of the insulation system in both outdoor applications and harsh or corrosive industrial applications. Akawell’s Coverwell is a flexible alternative to metallic-cladding systems. Although designed to work as a covering system for AK Flex materials, Akawell’s Coverwell is universally applicable and can be installed on site as a protective covering over a variety of other materials.
