Acrylic Storm Windows on the Patio Doors

I recently got a chance to do some computer work for Surecraft Plastics again and it was a great excuse to pick up some much larger pieces of acrylic to try to make a better "storm" window for the patio doors.

I even was able to get them to notch the panels for where the handle went - that was awesome!

First up we removed the old plastic film I had installed.  It was ugly, and the tape left a nasty residue.  We did our best to clean this off with some Goo-Gone/Goof-Off type material, I assume it's just concentrated acetone?  It was easy to get loopy from the fumes, so I'd suggest using it in a ventilated area if possible.

The original plastic film.  You can see some distortion here.
The notched piece for the door.  Complete with protective coating.
Starting with the removable caulk.
A good workout for both of us!
Trying to get a good, square fit.
A bit of painters tape and an old credit card to hold it in place.
A good look at the removable caulk through the acrylic.
Then we fitted in the larger sheets of acrylic, and tried to hold them in place with a combination of painter's tape and unused points cards.  I tried to press them against the frame to get them to stick to the removable caulk, but they sagged away quickly and it was a challenge to get it to work.  I didn't see it being a treat to do each window like this every fall.

After a day or two the acrylic was still in place, but sagging badly and exhibiting huge leaks around the edges where the caulking had allowed it to completely peel away.

I decided upon reflection that it could be improved and simplified by trying to fit the acrylic inside the frame of the patio doors, and then caulking over these edges where the caulk no longer had to provide structural support.

Kenny and I removed the panels, and with some difficulty tried to remove the caulk.  It was fine in some spots, but wouldn't come off in others.  I remeasured the panels to fit the new, smaller requirements, and tried to cut off the areas that were the worst for removing the caulk.

You can still see some of the "removable" caulk that just wouldn't come off.


Working around the handle.
Oh noes!  Lots of chips along the edge when I cut it down.  At least it should be hidden behind the frame...
I put the panels back into place, and added judicious amounts of painters tape, trying to avoid having to use the caulk again, as I am no longer convinced that it is either easy or complete in its removal.

This actually looks better than just the caulking, or so I think...
Big green lines, but they're neat, and hopefully easily removable?
Top corner looks okay.
This is where the panel sags inward at the moment, you can see that in the curve of the tape.
I did put back the silica gel pack to help ensure that no moisture would fog up the place.

Now it remains to be seen how it performs when there is a wind that creates large pressure differences, or just when we get another cold snap - we are predicted mild weather for the next week or so!


Of course, a tiny fleck of tape left on the far side of the acrylic.  Sigh.  Wabi-sabi.
