USES
PRODUCT DETAILS
-
Constructed from two layers of pure aluminum and two layers of polyester, encapsulating a galvanized wire.
-
Internal duct perforated over more than 25% of its surface area for significant attenuation of airborne noise.
-
Corrosion resistant, fully water repellent, and able to withstand high operating pressures thanks to quad-lamination.
-
High flame resistance, with internal and external walls made of non-combustible aluminum, and an adhesive with retardant agent.
-
Low internal friction coefficient, reducing system energy consumption.
-
Standard length of 25' in a 48'' box.
