Ventilation grille – GlasVent ZR AK (+)

This new ventilation grille with acoustic damping can be used for all glass thicknesses from 10 to 56 mm! Placement is possible above the glass (deduction 100 mm) or as calf placement. The GlasVent is ideal in combination with vacuum glass (for glass thicknesses from 9 to 12 mm). The aluminum ventilation flap ensures excellent water and wind tightness. This aesthetic suspense grille can therefore be used without any problems in high-rise buildings.

Advantages of GlasVent

For quiet living. Noise reduction up to 34 dB

Ideal in combination with BENGglas (>10 mm)

Excellent water and wind resistance

Suitable for new construction, renovation and high-rise buildings

Suitable for aluminum and wooden frames

Applicable to all glass thicknesses from 10 to 56 mm

Ventilation grilles: ventilation and acoustic functions

 

One of the most important advantages, in addition to heat insulation, is sound insulation. This is why it is crucial to invest in solid window frames and grilles that are also focused on acoustic dampening.

Duco understands this and has launched two models from this starting point, the GlasVent ZR AK and the GlasVent ZR AK+.
The plus variant offers better acoustic value and ventilation capacity and is therefore the superior product to use BENGglas
