Tubolit and Imcoa Pipe InsulationArmacell offers several closed-cell PE foam insulation systems for residential plumbing applications

Since 1954 AP Armaflex has been THE preferred flexible elastomeric insulation for commercial plumbing pipes. However, Armacell offers pipe insulation solutions for residential applications, too.

The low thermal conductivity of foam pipe insulation makes it an efficient thermal barrier.  The closed-cell foam structure offers excellent water-vapor transmission properties, which reduce the need for additional vapor retarders. Also, its thermal performance will not be impaired by surface punctures.

For residential applications, Armacell’s Tubolit®, Imcoa® and Tundra® products are practical, cost-effective solutions for pipe insulation.  Available in semi-slit Tubolit and Imcoa Pipe Insulationand self-seal configurations, these polyethylene foam tubes can be easily installed by homeowners. Available in 6-foot lengths, Tubolit, Imcoa and Tundra require no special tools for installation. Both Tubolit and Imcoa also come in a white self-seal option where a clean aesthetic is important.
