Step-By-Step process to board up plywood on sliding glass doors

After gathering all the elements, let’s start with the safety gears. Kindly check if your residence is allowed for boarding.


First, grab your measuring tape and count each window and sliding door. If your home has a problem with the roof, vent, or even any opening that can turn into an air entrance; count for them too. For doors add 8 inches and for windows add 4 inches in heights and widths both in measurement.

Speaking of measurement, we have an article on cabinet handle measurement you may like.

Normally plywood sheets come at 4 by 8 feet in total and following this info you can easily calculate how many sheets are needed, then cut accordingly. Remember, you mustn’t buy plywood sheets that are less than ⅝ inches thick + not CDX grade

Cutting & Drilling

Now cut your plywood sheets according to the window or door size with some extra space (Discussed above). If your door or window is larger than the sheet, join the panels with 2X4 braces from the outside. 

Afterward, you have to drill through the entire seam at 12 inches intervals and 2 inches from the edge. Then, place the sheet over and mark drill the mounting positions. For windows installed on wooden frames, you have to use lag screws ¼ inches to ⅜ inches with plastic coated anchors. 

If your window is installed on a masonry house, then use ¼ inch expansion bolt with galvanized expansion anchor. Both lag screw and expansion bolt must penetrate through the wall with the frame.

Mark, Coat & Set

In this phase, mark your panels so that you can use them sharp whenever needed. Make sure to have a coat of sealant of color on both sides of those panels.  And finally set every panel on each door or window and door to check everything is perfect. If not, then check which step from above has been missed or gone wrong.
