More About Foam and Fiberglass Pipe Insulation
Improperly insulated water pipes are huge sources of energy loss within homes and businesses. When hot water pipes aren't properly insulated, they leak heat, forcing your water heater to work harder to keep hot water at an ideal temperature. Inversely, cold water pipes that are not insulated will absorb heat, leading to warmer water and condensation on the pipes' surfaces. This can lead to moist conditions within your home or business, putting you at a much higher risk for a mold problem. Improperly insulated water pipes also stand a much higher chance of freezing in the cold winter months, which can lead to hundreds if not thousands of dollars in unwanted damages on properties in region where winter temperatures dip well below freezing.
With all of these potential problems stemming from improperly insulated water pipes, choosing to insulate should be a no-brainer. And with our high-performing and easy-to-use water pipe insulation products here at Conservation Mart, insulation is easier than ever. We proudly offer an extensive selection of foam and fiberglass pipe insulation products that simply slip over your pipes like socks to cut down energy costs by hundreds of dollars each year.

How to Choose the Right Foam Pipe Insulation
Selecting the right insulation depends on your environment, pipe material, and desired energy efficiency. Foam pipe insulation comes in several types and sizes to match different conditions and system requirements.
- Thermal Requirements: Higher R-values offer better heat retention for colder climates or hot-water lines.
- Pipe Diameter: Match the insulation size to the pipe’s outer diameter for a snug, efficient fit.
- Indoor vs. Outdoor Use: For outdoor applications, choose UV-resistant or weatherproof materials to prevent cracking and moisture damage.
- Installation Type: Self-seal insulation provides fast, clean installation, while non-adhesive options work well for larger commercial systems.
Use the product specs and filter tools above to find insulation that meets your temperature range, environment, and pipe size needs.
Frequently Asked Questions About Foam Pipe Insulation
Closed-cell foam insulation has a dense structure that resists moisture and offers a higher R-value, making it ideal for plumbing and HVAC systems. Open-cell foam is softer and less moisture-resistant, best suited for indoor or conditioned spaces.
Yes. Elastomeric and UV-resistant polyethylene foams are designed to handle outdoor conditions, protecting pipes from sunlight, moisture, and temperature fluctuations.
Foam insulation helps retain heat inside the pipe, reducing temperature loss and preventing freezing in cold weather. It also keeps condensation from forming on cold-water lines.
Many foam sleeves feature a self-sealing edge that eliminates the need for extra tape. Non-adhesive insulation can be secured with foam tape, wire ties, or clamps at joints and ends.
