Propex Acoustic Ducting 65mm (per metre)
Technical hot air ducting suitable for use on 2kW heaters. This ducting is designed to reduce any noise transmitted through the ducting from the heater as well as air noise associated with it moving through the ducting.
Acoustic ducting has a wide porosity rating of 50–500 Hz and so deadens a range of frequencies.
Test have shown that maximum effect will be gained when using 1 metre of ducting and this should be positioned any where within the ducting run between the heater and first outlet.
