Window Guard Guidelines

To prevent the possibility of a window fall in your home, please follow the simple instructions listed below:

 Window Safety Check List

(    )  1. Determine which windows are dangerous.

Keep in mind, even a fall of 6 feet can cause serious injury or death to a small child.

Never depend on window screens to protect your children from a fall.Today’s window screens are only secured with a thin rubber gasket and are not designed or intended to be a childproof barrier.


(    )  2. Take preliminary actions to avoid a catastrophe.

Keep furniture a safe distance away from windows to prevent children from climbing near them.

Until window guards are installed, open windows from the top, not the bottom, whenever possible. Do not exceed an open spacing of more than 4 inches for any gap.


(    )  3. Determine which type of windows you have and take measurements.

These are the most common types of windows, where the bottom pane opens vertically. If the top pane is moveable, this is a double hung window. If the top pane is fixed, it is a single hung window.

For these types of windows, take a left to right measurement inside the window frame (See above illustration). Consult the individual manufacturer’s instructions for proper installation.


Casement windows do not have a top and bottom pane, the entire panel(s) open by either sliding horizontally or by opening outwards with a crank. It is important that the entire opening is guarded for this type of window because the entire panel opens. In some cases, guards can be mounted vertically on these types of windows. In other cases, it is best to mount the guards horizontally and stack them vertically.

For this type of window, take a left to right measurement inside the window frame and also measure the overall height inside the window frame. Contact the supplier with this information to determine the best method to guard these windows. Consult the individual manufacturer’s instructions for proper installation.


(    )  4. Install window guards and window stops on all windows that propose a hazard.

Points to consider when selecting a window guard:

** For windows on or below the 6th floor, window guards must be easily removeable by adults and older children in case of emergency.

** Try to choose a guard that conforms to the ASTM Standard (F2090-01a) for window guards.

** Look for guards that come with either a guarantee or a warranty. It is not worth jeopardizing your childrens’ safety with inferior window guards.

** Contact a manufacturer of a window guard. Do they offer product knowledge, technical assistance and product assistance?

** Be sure to select the correct window guard for your type of window. Installing the wrong window guard can be dangerous and greatly increase the risk of accidental window falls.


Locate a window guard supplier  and order guards for all necessary windows.

Purchase window stops (available at many hardware stores).

Install window guards and window stops together. Be sure that window stops are installed to prevent the window from being opened more than 4 inches above the top bar of the window guard.

Make sure that all adults and older children in the household know how to remove the window guard in case of emergency.


(    )  5) Check window guard(s) and window stops frequently.

Make sure that all window guards and window stops are secure and operating correctly.


(    )  6) Never leave children unattended !

Window guards are intended as a deterrent to window falls, but not as a replacement for proper adult supervision.
