Lift out secondary glazing units

 

 

The Secondary Glazing Standard Lift Out is a removable secondary glazing panel within its own outer frame that is fixed to the face or reveal of the existing primary window.

 

The integral finger lift bar at the bottom of the panel allows it to be lifted up into the top of the secondary window outer frame and then swung inwards to facilitate removal.

 

If fire escape (fire egress) is required: opening width or height must be a minimum of 450mm together with a clear openable area of no less than 0.33m².
