Coated Nitrile Pipe Insulation - 22mm x 25mm - Black Isopipe Self Seal - 28m Box

Slit & Seal Ready to use External Lagging. What is Isopipe TC Solar? Isopipe TC Solar is a weather resistant elastomeric insulation system, designed specifically for long term outdoor exposure. It combines the core NBR closed cell insulation with a durable polyolefin external skin engineered to withstand sunlight, harsh weather, and atmospheric pollutants. Why ISOPIPE TC Solar? Polyolefin protective membrane; a tough, polymer-based outer skin that resists UV degradation, moisture, and environmental wear, making it suitable for exposed pipework. With a closed cell NBR insulation core it provides excellent thermal performance, condensation control, and low water vapour permeability. Offering long term outdoor durability specifically engineered for heat pump, heating, cooling, and plumbing applications where insulation is exposed to sunlight and weather. When it is used? Isopipe TC Solar is chosen when standard elastomeric insulation would degrade outdoors. The polyolefin skin eliminates the need for additional cladding, painting, or taping, offering a clean, professional finish with minimal maintenance and no need for top up coats. Its especially suited to heat pump pipework, rooftop services, and any installation where pipes are continuously exposed to sunlight and weather.
