Armaflex Sheet Insulation Lagging Black Foam Class O Nitrile Rubber (0.5 x 2m rolls)

From £42.35

Armaflex Class 0 Flat sheet: 0.5 x 2m rolls. 

The Armaflex Sheet Insulation Lagging, characterized by its notable black foam and crafted meticulously from Class O Nitrile Rubber, is the epitome of proficient flexible insulation, designed meticulously to ensure consistent and reliable condensation control. This sheet material is not only a specialized insulator but also a protector of your systems against potential risks, such as Corrosion Under Insulation (CUI).

Key Features

  1. Inherent Water Vapour Barrier: The Armaflex Sheet has an intrinsic water vapour barrier that markedly reduces the risk of CUI, ensuring that the material beneath the insulation is safeguarded against potential moisture and consequent corrosion.

  2. Optimized System Reliability: When paired with ArmaFix AF pipe supports and ArmaFlex adhesives, the insulation sheet ensures the highest system reliability, fortifying its position as a trustworthy solution in various application areas.

  3. Stable Thermal Conductivity: Its stable thermal conductivity ensures long-term energy efficiency, safeguarding systems against unwarranted energy losses, and thereby contributing to sustainability and cost-effectiveness.

  4. Microban® Antimicrobial Protection: The built-in Microban® antimicrobial protection significantly reduces the potential for mould and bacteria growth, ensuring a hygienic surface and preventing the degradation of the material.

  5. Enhanced Adhesion with Self-seal Tubes: The availability of self-seal tubes, specifically with a tangential cut, enables stronger adhesion, ensuring a robust, tightly sealed insulation system.

  6. Exceptional Fire Performance: With a rating of Euroclass B/BL-s3, d0 for the entire range, the Armaflex Sheet demonstrates excellent fire performance, enhancing safety standards across application areas.

  7. FM Approved: The FM approval further accentuates its credibility and compliance with stringent quality and performance standards.

The Armaflex Sheet, with its unique microcell structure, facilitates a straightforward installation process, eliminating the need for an additional vapour barrier and thereby reducing both material and labor costs. It combines a very low thermal conductivity with an extremely high resistance to water vapour transmission. This dual functionality not only thwarts long-term energy losses but also inhibits moisture ingress, effectively minimizing the risk of CUI.

Moreover, the material is imbued with Microban® antimicrobial protection, which offers an additional layer of defense against mould and bacteria growth, ensuring that the insulation retains its integrity and effectiveness over an extended period. This feature is particularly pivotal in public buildings and process industries, where hygiene and durability are paramount.

The Armaflex Sheet Insulation is not merely a product but a comprehensive solution. When used in tandem with pipe supports, fire sleeves, and adhesives from the AF/ArmaFlex Class O family, it provides a holistic insulation solution, catered to a wide array of applications. Whether it's utilized in public edifices, industrial settings, or specialized process industries, the Armaflex Sheet Insulation affirms itself as a robust, reliable, and efficient insulation solution, adeptly balancing performance with longevity and reliability.

Whether safeguarding against energy losses, preventing CUI, or ensuring a safe, hygienic, and fire-resistant environment, the Armaflex Sheet Insulation Lagging stands out as a superior choice in delivering a high-performance insulation solution across various applications and industries.
