K-Flex self-adhesive foam tape is made with superior quality foam and is highly flexible. The closed-cell nature of the elastomeric foam makes it suitable for hot and cold thermal insulation. The features of foam insulation tape like its low thermal conductivity, high water vapour diffusion resistance and low flame spread make this self-adhesive tape ideal for sealing the insulation around pipes, ducts and others together.

These self-adhesive foam pipe insulation tape from K-Flex helps save energy. They perfectly seal any gaps between the insulation and cover the tiny gaps. Since K-flex foam insulation tape is made of the same material as the K-flex sheets and foam lagging, it has the same excellent moisture resistance and thermal qualities. The factory-applied pressure-sensitive adhesive (PSA) attaches firmly and establishes a long-lasting connection.
