About Selecting Thermal Insulation

Economical Flexible Polyethylene Foam Pipe Insulation

Less flexible than rubber foam, this insulation restricts absorption of water, air, and gas. It is typically used in plumbing applications. Seal with contact adhesive (sold separately). To use outdoors, coat in acrylic paint.

Slit tubes have an adhesive strip closure.
