Product Description

AF/Armaflex Class O Self seal Black Pipe Insulation is a pre slit thermal insulation product with two strips of double sided self-adhesive tape applied to each open seam. Specially developed to provide insulation where fast, secure installation is required and ideal for applications where working space is restricted, AF/Armaflex Class O Selfseal is easily applied by fitting the insulation onto the pipe, peeling back the self adhesive tape and closing the seams together.

AF/Armaflex Class O Selfseal Pipe Lagging has a closed cell structure with an in-built vapour barrier, providing a high resistance to water vapour transmission, reducing the condensation risk and helping to increase the product life span.
