The standard component sizes

of the WinTwinR1 system set with

- neusrubber 1500mm

Placement

with the three profiles is exceptionally straightforward, and takes little time. The application of counter-weights requires more space compared to balance springs.

The sash window with the Win Twin R1 system set achieves

closure entirely eliminating air and water infiltration.

Hence it complies with the NEN 3661 and ISO/DIS 8247 (600 Pascal).

In order to balance the window,

a set of counter-weights is used. As a rule, the counter-weight system relies on steel counter-weights of 50x70mm dimensions, weighing
ca. 28 kg/m¹.

The weight of the window preferably is <150 kg.
