Good Questions: Drilling Into Sliding Door Edges?

Hello AT,

I have a question regarding modifying a sliding glass patio door. We live in an apartment with a small yard in Williamsburg.

We recently installed an insert into our patio door track, in order to provide a doggie door for our beagle. We weather-stripped the edge of the insert, and the door itself, but the joint is not airtight, and leaks cold air into our apartment.

We want to know if it is ok to drill into the edge of the sliding door, so that we can attach an aluminum bracket which will sheath the edge of the pet door insert and provide a better seal...

Our concern is that the door is double-paned, and it is possible that the space between panes is evacuated, or filled with an inert gas such as Argon. We would not want to damage the insulating capability of the door itself.

Has anyone tried anything like this? We only want to drill into the metal edge of the frame.

Any advice would be appreciated!!

Thanks, matt


Our best guess is that you CAN drill into the sides of these doors as there should be some space before you come to the glass, but it is dicey.

Have you considered applying the strip with an industrial cement or glue, OR using a fabric or a Velcro type of thing to make a seal on the outside?

Anyone else?
