Armaflex EVO Benefits
Performance Benefits
- Euroclass B‑s2,d0 fire performance with enhanced low‑smoke behaviour, supporting high‑spec commercial & industrial installations.
- Advanced closed‑cell elastomeric structure delivers exceptional vapour resistance, protecting chilled water and refrigeration lines from long‑term condensation risk when installed correctly.
- Low thermal conductivity (as low as 0.033 W/m·K at 0°C) helps maintain system efficiency and reduce operational energy losses.
- Microban® antimicrobial protection built into the pipe insulation material to inhibit mould and bacterial growth in sensitive or hygienic environments.
- High moisture resistance ensures stable performance in humid plantrooms, cold stores and high‑load mechanical spaces.
Practical Benefits
- Flexible, lightweight construction makes EVO easy to handle and install, even in tight service voids or retrofit environments.
- Clean, accurate cutting and shaping thanks to the material’s refined elastomeric formulation, reducing installation time and waste.
- Durable, impact‑resistant surface maintains its integrity in demanding commercial and industrial settings.
- Consistent, premium finish that enhances the appearance of exposed pipework and supports professional installation standards.
- Wide application suitability, including HVAC, chilled water, refrigeration, heating, plumbing, tanks, vessels and process equipment.
- Long service life due to its resistance to moisture ingress, ageing, UV exposure (when coated), and mechanical stress.

Frequently Asked Questions
What is Armaflex EVO pipe insulation?+
Armaflex EVO is a next‑generation flexible elastomeric foam insulation with improved fire‑retardant properties, low smoke generation, a closed‑cell structure and built‑in Microban® antimicrobial protection. It is designed for HVAC, refrigeration and process equipment applications.
What fire rating does Armaflex EVO have?+
Armaflex EVO is classified as Euroclass B/B(L)-s2,d0 under EN 13501‑1, offering enhanced fire safety and low smoke generation. It also carries EI30–EI90 passive fire resistance ratings when used in tested system configurations, providing a level of protection not typically found in standard nitrile rubber insulation.
Is Armaflex EVO suitable for condensation control?+
Yes. Armaflex EVO uses a closed‑cell elastomeric structure with high vapour resistance, making it highly effective at preventing condensation on chilled water, refrigeration and low‑temperature pipework. This is one of its primary design functions.
Does Armaflex EVO include antimicrobial protection?+
Yes. Armaflex EVO contains built‑in Microban® antimicrobial additives that inhibit mould, mildew and bacterial growth. Armacell is the only flexible technical insulation manufacturer offering integrated Microban protection.
What temperature range can Armaflex EVO be used in?+
Armaflex EVO can be used between -50°C and +110°C, or up to +85°C when sheets or tapes are fully bonded to the substrate. This makes it suitable for chilled water, refrigeration, HVAC and many heating applications.
Is Armaflex EVO easy to install?+
Yes. Armaflex EVO is flexible, lightweight and available in self‑seal tube options for faster installation. Armacell recommends using ArmaFlex 525 or ECO550 adhesive for long‑term system performance.
What pipe sizes and insulation thicknesses are available?+
Armaflex EVO is available in a wide range of inner diameters and nominal wall thicknesses, including 6–114 mm pipe sizes and 9 mm, 13 mm, 19 mm, 25 mm and 32 mm insulation thicknesses. Sheets and rolls are also available for tanks, vessels and large surfaces.
Does Armaflex EVO support BS 5422:2023 compliance?+
Yes. When installed at the correct thickness for the application, Armaflex EVO can be used to meet BS 5422:2023 and Part L insulation requirements for HVAC and building services. (This is based on its thermal conductivity and performance characteristics.)
