Impact windows are typically only used in areas close to the coast. There are two ways to determine if your 1620 is an impact or standard window.
One way is to look at the AAMA label, which should be found at the head of the window. If the AAMA label says, “Missile Level D, Wind Zone 3, Conforms to ASTM E1186 & E1996,” your window is an impact window. If that language is not on your AAMA label, your window is not part of the recall.
The second way is to look at the tilt latches. The tilt latches are found on the top of the lower (operable) sash of your window. There are two, one on the left and one on the right side on the top of the sash frame. The tilt latches on the 1620 impact window are surface mounted, meaning they sit on top of the sash frame, and attach to a metal hook in the balance pocket. The tilt latches on the standard, non-impact 1620 window are recessed, meaning they sit inside the sash frame, and are not attached to a hook in the balance pocket. If your tilt latch is mounted to the top of the sash frame, meaning it sits on the surface of the sash frame, and is attached to a hook in the balance pocket you have an impact window. If you do not, your window is not part of the recall.
