Kingspan Duo Therma Flap Ventilator


Kingspan Duo Therma

Cold bridge-free, thermally insulated smoke ventilator

The innovative twin flap system employed by Kingspan's Duo Therma product make it ideally suited for buildings which have stringent requirements for air sealing and thermal and/or acoustic insulation, as well as for structures with high moisture levels.

A thermally insulated alternative is also offered, which will minimize the formation of condensation, and the product can also be supplied uninsulated, translucent, and with a single flap instead of two.
