Internal sash for VELFAC 200 windows
The internal sash
of a 2+1 window significantly improves
acoustic and thermal properties. In order to constantly maintain this
improvement, the internal sash must remain closed. It can be tophung
or sidehung and can be equipped with either handles or screws
depending on whether the sash will be opened in daily use or only for
cleaning purposes.
The sidehung sash is opened
by turning the small handle(s) and
pulling inwards. The sidehung sash can be opened for both ventilation
and cleaning. The tophung sash should only be opened for cleaning
purposes and should be completely dismounted before commencing.
