Plenum boxes are one of the basic components of any ventilation system, providing the link between ductwork and terminal. Constructed from galvanised steel as standard, we can also manufacture plenums in stainless steel or aluminium if required. A comprehensive range of options is available to enhance functionality or aid fitting including:
Fire rating- By increasing the material thickness to 1.2mm and installing a 120 minute rated intumescent fire damper (not available with aluminium boxes).
Lining- For both thermal and acoustic performance, plenum boxes can be internally lined with 10mm pyrosorb type foam insulation. This can help to to reduce cross-talk between rooms, absorb noise from fans or other machinery, and also thermally line the box to help avoid any problems with condensation.
Drop rod fixings -Spot welded, pre-punched angle brackets to accept drop rods can be factory fitted, making installation quick and simple.
