Description
Anti-Condensation Membrane (felt) is a new type of needle punched polyester non-woven fabric, produced by amending processing and special technology. It is a product designed to eliminate the problem of condensation. When the temperature and humidity conditions reach the dew point, the moisture condenses on the underside of the metal roof and forms droplets of water.
Anti condensation felt is a flame-retardant self adhesive felt fabrics for metal roof and solve condensation problems in metal buildings, it could replace insulation materials. If you are looking for drip stop for metal roof or Anti-condensation felt manufacturer, Pls contact us.

FAQ
Q: How does your anti-condensation fleece compare to traditional vapor barriers?
Our membrane actively manages moisture phase changes rather than simply blocking vapor, making it ideal for temperature-volatile environments.
Q: Can this be installed under existing metal roofing?
Yes – our anti condensation felt is approved for retrofit applications when using our QuickSeam™ adhesive system.
Q: Do you offer technical support for OEM integrations?
Our engineering team provides free system compatibility analysis and CAD details for manufacturing partners.
