Brakel® Duo Therma
DUO THERMA Cold bridge-free, thermally insulated smoke ventilator
The innovative twin flap system employed by Brakel Airvent’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.
The Duo Therma is constructed from tempered aluminium, which is sea water and corrosion resistant AIMg3, sealed around with coated EPDM-rubbers which prevent freezing and guarantee a high level of air sealing.
As the aluminium is corrosion-resistant, it is supplied untreated as standard. However, if desired Brakel Airvent can supply the Duo Therma powder coated in any RAL colour. It can also be designed to incorporate 44dB noise-damping flaps, cold bridge-free base and flaps or with glass infill panels.
