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.

Armacell offers the widest range of backer rod materials for use in cold- and hot-pour sealant applications.

Backer rods are round, flexible lengths of foam that are used as a “backing” in joints or cracks to help control the amount of sealant used or the depth of the sealant in the gap. Some applications require closed cell back-up material that won’t absorb moisture, others seal best with open cell foam that is highly compressible and will fill irregular joints more evenly. No matter your application, Armacell offers the most extensive collection of backup materials and the largest range of sizes on the market. Combined with outstanding service, prompt delivery and competitive pricing, Armacell is the only one-stop source for all your backer rod requirements.

Consumers will find FillPro™ backer rod in many hardware stores and Sealant/Accessories distributors in the US and Canada.
