HOW TO ADD A GLASS WINDOW TO A HOLLOW CORE DOOR

Few of us live in homes with solid wood doors. Hollow core doors do the job on a budget, but they aren’t always, er, beautiful.

How to Add a Window to a Hollow Core Door

You will need the following supplies

-  One interior, hollow core door! -  A glass insert  -  ¾” board material for bracing -  ¼” x 2 poplar “craft board

-  Skill saw -  Jig saw (or hand saw) -  Trim nailer -  Caulk gun

Tools you will need:

My interior doors are typical “builder grade” six-panel, hollow core doors. When you cut into them you will find they are exactly what they say they are…hollow. 

I cut out the top four “raised panels” on the door. This cut doesn’t have to be “exact” but try to keep it fairly “square.”  I used my skill saw to cut the straight runs and then a jig saw to cut out the corners.

After I cut the hole in the door, I added bracing between the “skins.”MOST hollow core doors will measure 1 1/8” between the skins, but measure the INSIDE between the skins…that will give you the width of your bracing.
