Opening and closing windows

Outward-opening casement windows

There are two types of handle – locking and non-locking.

Locking handle - Step One

If the window is locked, unlock it using the key provided. Remove the key. Push the button on the handle and turn the handle 90°. Then push the window to the position you want.

Locking handle - Step Two

To close, pull the window closed and turn the handle 90° back to its original position. Relock the window and remove the key for security and child safety.


Non-locking handle

Push the button on the handle and turn the handle 90°. Then push the window to the position you want.


Top-hung window

When closing top-hung windows, take care not to twist the handle downward as you pull the window to close it.

Flying mullion casement

Flying mullion casements operate in the same way as a single window casement. It is only the opening sequence that makes them different. The main (primary) window needs to open first and close last to prevent the windows from clashing.


Tilt and turn windows

Tilt and turn windows can have two opening positions.


Leaning in at the top to allow controlled ventilation.


Opening inward for cleaning and greater access.


Locking/Unlocking - Step One

Lock and unlock the window with the key provided.

Locking/Unlocking - Step Two

Press the button and turn the handle 90°, pull the window towards you into the tilt position.

Locking/Unlocking - Step Three

If you have the optional variable tilt device fitted, when tilted, further turn the handle to place the window in the tilt position you want.

Locking/Unlocking - Step Four

To close the window, press the button and turn the handle a further 90°. Gently pull the window open into the turn position.


Vertical sliding windows

Step One

Unlock the catches with the key provided and turn the lever 180°.

Step Two

You can then slide the windows open for ventilation by pushing the bottom window up or pulling the top window down.


Some windows are fitted with spring-loaded child restrictors, which limit how far the window can open to approximately 100mm. They can be locked in the open or closed position.

Unrestricted closed position – turn the key anticlockwise to unlock.

Restricted open position – turn the key clockwise to unlock and limit how far the window can open to 100mm.

1) Limited window opening

2) Spring-loaded restrictor shown limiting how far the window can be opened. Press and slide window to open position.


Secondary double glazing

Undo the handle and slide the window away from the frame to the position you want.

Undo the latch and slide the window upwards to the position you want.

Undo the latch to unlock the window.

Once the window has been unlocked, the window will swing open. There is no fixed position when open.


Fully reversible casement window

Fully reversible windows open in the same way as shown for casement windows.

Step one

The window has an automatic safety restrictor which restricts the initial opening to about 100mm (until it is released).

Step Two

The safety restrictor, on the left-hand side of the window, is released by pushing the button marked ‘PRESS’ until it passes the two stops in the aluminium channel.

Step Three

The fully reversible window can turn 180° to allow it to be cleaned easily from inside. Pull down the casement top rail with both hands. The automatic restrictor acts as a reverse restrictor in two positions, allowing the window to be cleaned safely.

Step Four

To return the window after it has been cleaned, push the button marked ‘PRESS’ as before and lift the casement top rail. To close the window, push the button marked ‘PRESS’ and pull the window closed and follow instructions.
