    It has a Zero Ozone Depletion Potential (ODP) and a low Global Warming Potential (GWP). It is also often GREENGUARD® Gold certified for low VOC emissions.  

15. Can ArmaFlex AC Class O be used outdoors?
    While it offers some UV resistance, for prolonged outdoor exposure, it is recommended to protect it with a suitable UV-resistant coating like ArmaFinish FR.  

16. How does ArmaFlex AC Class O compare to standard rubber insulation?
    ArmaFlex AC Class O often offers superior fire performance (Class O rating), better water vapor diffusion resistance, and may include antimicrobial protection.  

17. What are the different forms of ArmaFlex AC Class O available?
    It is available in tubes (in various sizes and thicknesses, including continuous coils), sheets, and self-adhesive versions for ease of application.

18. Is ArmaFlex AC Class O suitable for use in hospitals and schools?
    Yes, its Class O fire rating, fiber-free nature, and available Microban® protection make it suitable for use in environments with stringent air quality and safety requirements.  

19. What is the shelf life of ArmaFlex AC Class O products?
    Self-adhesive versions (tapes, sheets, tubes) typically have a shelf life of one year when stored in dry, clean conditions at recommended temperatures.

20. How does ArmaFlex AC Class O compare to ArmaFlex Ultima?
    While both offer excellent insulation, ArmaFlex Ultima typically boasts even higher fire performance (Euroclass BL-s1,d0 with very low smoke) and may have slightly different thermal conductivity values. The choice depends on the specific project requirements and fire safety regulations.
