Upgrade your pipework efficiency with ISOPIPE TC Slit & Seal, the professional choice for high-performance thermal insulation. Engineered from advanced NBR-based closed-cell synthetic rubber, this flexible pipe insulation provides outstanding resistance to water vapour transmission (μ ≥ 10,000), effectively preventing condensation and protecting against frost.
Specifically designed for already existing pipe systems where traditional insulation cannot be easily threaded, the ISOPIPE TC Slit & Seal features a pre-slit design with a secure double bonding system. This system includes a strong inner self-adhesive mesh tape and an outer self-adhesive overlap membrane, ensuring a continuous seal and reducing installation time by up to 50% compared to traditional glue-based methods.
Key Performance Characteristics
- Outstanding Thermal Performance: Features a low thermal conductivity (λ = 0.036 W/mK at +30°C) to maximise energy savings in heating, cooling, and refrigeration applications.
- Temperature & Environment: This rubber insulation has anoperating range from -50°C to +110°C,making it ideal for a large range of applications
- Safety Guaranteed: ISOPIPE TC material is guaranteed through rigorous supervision and factory tests, meeting Euroclass B-s2, d0 fire performance standards to prevent flame spread.
- Versatile Fit: Available in various thickness options (including 19mm thickness) and pipe diameter sizes like 15mm to suit any vessel, fitting, or straight run.
Applications:
- Heating & Plumbing: Prevents heat loss and provides frost protection for domestic and commercial heating pipes.
- Air Conditioning & Refrigeration: High resistance to water vapour prevents condensation on cold pipework.
- Industrial Use: Insulates vessels, fittings, and large-scale cooling systems.
- Retrofitting: The pre-slit design with self-adhesive overlap allows for insulation without disconnecting pipes.
- Nitrile rubber pipe insulation is 2m long, Available in 15-28mm size in 9-19mm thicknesses
- Flexible, Class O pipe insulation for all project types.
- Has a secure double bonding along the slit's length, with strong inner self-adhesive mesh tape and self-adhesive overlapping tape ideal for DIY pipe insulation.
- It is pre-cut at angle offering a larger bonding surface, better adhesive properties and less risk of heat loss
- Gives an attractive appearance and professional finish
- Used to minimise condensation and sweating in pipework
