Glas Vision 3000 windows have been fully independently tested by ift Rosenheim in Germany (full test results are available on our downloads page) for ease of movement of operating handles to disengage, open, close and re-engage.
The sample windows were tested to EN 12046 : 2003-11 and the results are classified in accordance with EN 13115 : 2001-07.
Where specified, the majority of UK buildings require the operating handles to need no more than 10Nm of torque (Class 1) to open the windows in general use. Where consideration for those less abled is to be made in the window design, then a maximum of 5Nm is generally considered appropriate (Class 2) and the Vision 3000 side hung casement can be used.
The performance levels achieved by the Vision 3000 product make the side
hung open in casement appropriate for Class 2 applications and the tilt and
turn appropriate for Class 1 applications.
