MasterLine 8 SoftTone

Sound attenuating parallel outward opening window

The comfortable living space

MasterLine 8 Softone is the sustainable architectural solution for natural cooling and ventilation in urban environments. The parallel opening windows allow maximal ventilation and cooling; the Softone components inside the window reduce the noise nuisance. This results in a fresh and healthy working and living experience in the heart of a vibrant city.

The focus application fields for this solution are the noisy city centers and living spaces near highways, railways, and airports. MasterLine 8 Softone is a more sustainable, affordable, and incredibly low-maintenance alternative to mechanical ventilation and comfort cooling.



Between countries, there are differences in how a window is placed into the wall. For more information on the usage of Reynaers BIM models, download the BIM guidelines.
