Description
Class 0 PVC Nitrile Insulation Rolls for HVAC, Pipe Lagging & Condensation Control
PVC nitrile insulation rolls are a high-performance closed-cell elastomeric insulation solution designed for HVAC systems, pipe lagging, duct insulation and condensation control.
Engineered for commercial and industrial use, this flexible nitrile insulation roll provides excellent thermal efficiency, fire-rated performance and long-term moisture resistance — making it ideal for heating, refrigeration, ducting and chilled pipework applications.
Available in plain or self-adhesive backed rolls, these insulation sheets allow fast, clean installation on flat or curved surfaces. For pipe insulation systems, view our insulation tubes and lagging products for faster installation on straight runs.
✅ Key Benefits
- Class 0 fire-rated insulation (Euroclass BL-s2, d0)
- Excellent condensation control for chilled pipework
- Closed-cell structure prevents water absorption
- Wide temperature range: -165°C to +110°C
- High vapour resistance for long-term performance
- Flexible & easy to install on pipes, ducts & equipment
- Available self-adhesive for faster installation
- Resistant to mould, fungi & bacteria

🔥 Why Choose PVC Nitrile Insulation?
PVC nitrile Class O insulation roll is widely used in HVAC insulation and building services because it offers:
- Superior condensation control vs open-cell foam
- Excellent thermal insulation performance
- Long-term durability in demanding environments
- Compliance with Class 0 fire safety standards
✅ PRO TIP FOR INSTALLERS
The best-performing insulation systems use all three together:
-
Tubes for pipe insulation on straight pipe runs – Self-Sealing Pipe Insulation Lagging for Condensation Control & Energy Saving | K-Flex ST
-
Rolls on ducts, tanks & equipment
-
For joint sealing and finishing, use insulation tape to create a fully sealed vapour barrier.
This creates a fully sealed, vapour-tight insulation system — maximising energy efficiency and preventing condensation failure.
