    Polyethylene Foam Pipe Insulation

    An economical choice, this insulation is ideal for light duty plumbing and HVAC. Like rubber foam insulation, it repels moisture to keep temperatures stable and protect pipes from corroding. However, it's less flexible.
    Solid Tubes

    Slide these tubes over new sections of straight pipe as you assemble a line. You can also cut them wherever you need to make custom splits.
    Coatings—Add a coating of acrylic paint to repel moisture and protect against UV and ozone damage.
    Contact Adhesives—Secure insulation to pipes and seal gaps between sections.

    Polyethylene Foam Pipe Insulation Sheets

    Image of Product. Front orientation. Pipe Insulation. Polyethylene Foam Pipe Insulation Sheets.
    An economical alternative to rubber foam insulation—trim these sheets to fit pipe with unique shapes and sizes. Like rubber foam, it repels moisture to keep temperatures stable and protect pipes from corroding. However, it's less flexible.
    Coatings—Add a coating of acrylic paint to repel moisture and protect against UV and ozone damage.
