TUBE INSULATION WITH ALUMINIUM CLASS0
NANOFLEX tube (T2) with aluminum layer is highly puncture and tear resistant. Contains flame retardants and can be used as the exterior of hot or cold insulation. This product also provides excellent vapor barrier performance.
In particular for outdoors application, it has good anti-aging properties and is resistant to all weather conditions.
We are offering 4 grades of aluminum for multi-purpose applications.
