Tundra closed-cell polyethylene foam semi-slit pipe insulation protects pipes in residential and light commercial plumbing projects from heat loss and freezing damage. This durable foam wrap prevents costly repairs caused by frozen or damaged pipes while reducing energy loss in hot and cold water lines.
With its low thermal conductivity and very low water vapor transmission rate, this insulation wrap maintains optimal pipe temperature across a broad service range of -297°F to 200°F. The closed-cell polyethylene construction resists moisture absorption and provides consistent performance year-round, making it suitable for use over cold and hot water systems, refrigeration lines, air conditioning lines, and heat-traced pipes.
Features and Benefits
- Excellent Thermal Protection: Low thermal conductivity minimizes heat loss from hot water pipes and prevents freezing in cold climates.
- Chemical and Moisture Resistant: Closed-cell polyethylene construction resists water vapor transmission and chemical degradation for long-lasting performance.
- Broad Temperature Range: Operates reliably from -297°F to 200°F, handling extreme seasonal conditions.
- Compatible with Heat Tape: Acceptable for use with heat tracing systems for additional freeze protection in vulnerable areas.
- Versatile Applications: Works on refrigeration and HVAC lines in both residential and light commercial settings.
- Semi-Slit Design: The semi-slit construction accommodates standard plumbing installation methods.
