Description
The AD-INS insulated access door features a double-skin galvanised steel panel filled with 25 mm mineral wool insulation, delivering excellent thermal performance and condensation resistance.

The door is designed for installation on insulated rectangular ductwork carrying conditioned air, where uninsulated penetrations would cause energy loss and surface condensation.
