Vengen28 Glazing Instructions

Glass is to be supplied for on-site glazing.


We suggest glazing is carried out after fixing window to structure. (See Vengen28-003 dated 16.03.2016)


Glazing Method Fully open window. On actuator units it is necessary to disconnect the handle. For D&H actuator operated windows the actuator will need to be removed. To do this you will need to remove plastic end caps, disconnect cable & undo screws top & bottom. (Figure 1/1.1)

Remove 2 No frame screws from each end of Louvre head rail and take off horizontal glaze bar. (Figure 2)

Slide glass unis into “goal post” frame and re-fit head rail.

Close the window to fit the internal glazing wedges wedges. Fit Head and Cill rail wedges first followed by side rail wedges (Wedges supplied in rolls for cutting in site to suit). Repeat for each Louvre glass unit. (Figures 4 & 5)

After glazing it may be necessary to re-level and square the head and cill rails. To do this apply pressure at centre points of rails as indicated on Figure 6.

Check and seal frame corners at junctions of head, cill and side rails with small joint sealant.

Upon first operation of the Louvre actuator, 24vDC should be applied to the brown core in the cable to fully open the blades to their furthest extent. The actuator has an internal limit switch which will activate at this point. 24vDC should then be reversed to the white core in the cable to fully close the blades. The Louvre actuator is now calibrated and ready to operate.
