VERSATILE APPLICATION - Ideal for professionals and DIY enthusiasts. The Armaflex AF insulation mats in thicknesses of 6-32 mm are ideal for professional applications in heating, air conditioning, refrigeration and sanitary technology - e.g. for insulation of pipes, ventilation ducts, fittings or containers. Thanks to the self-adhesive back and flexible structure, they can be easily cut and mounted even in the DIY area - e.g. in cellars, garages, caravans or for subsequent insulation in the house.
Robust & durable in many environments. Temperature range from -50 °C to +110 °C (up to +85 °C with full-surface bonding), UV-resistant (when exposed to the outside, with protective coating) and reduces body noise by up to 28 dB A - for long-term insulation effect even under extreme conditions
Integrated Microban protection - Hygienic safety with every use. Thanks to the integrated Microban technology, the growth of mould, bacteria and fungi is inhibited directly in the material - permanently and without additional effort. This makes the mat ideal for sensitive areas such as food processing, laboratories, healthcare or pharmaceutical industry. Also in the private sector, it ensures a more hygienic indoor climate - perfect for cellars, home installations and DIY projects.
Highest insulation performance for a wide range of application thicknesses (6-32 mm). The Armaflex AF mat offers very low thermal conductivity (λ≤0.033W/(m·K) at 6-32mm) and high water vapour resistance (μ≥10,000) - ideal for preventing condensation, minimizing energy losses and preventing corrosion under insulation (CUI). Perfectly matched to common system requirements and tested application criteria
Fire protection according to Euro class B-s3.d0 - more safety in everyday life. Armaflex AF meets strict European fire protection standards (EN 13501-1, B-s3,d0) - it is flame retardant, develops only limited smoke and does not drip when exposed to heat. This makes the mat suitable for applications in public buildings, residential buildings, schools or technical facilities where increased requirements are placed on preventive fire protection.
