Insulating Sliding Glass Doors
My bedroom has a sliding glass door, which is not insulated. Therefore, the room is almost impossible to keep warm. Since I can't afford to replace the door with insulated glass, what else can I do? I was thinking of hanging a thick blanket or moving pad over it, but that would also block the light. Do you have any good ideas?
Insulate with Bubble Wrap
I've used bubble wrap on my windows. I sprayed the window with water and then stuck the bubble wrap to the window. Plenty of light still comes in, and I think it helps with the cold.
Adhere Plastic Film
I don't know where you live, but check your local hardware store. Where I live (it gets very cold), there's a plastic film that you can adhere to the inside frame/trim of your windows and doors using a special two-way tape included in the kit (plus you need your own scissors and a hair dryer). You effectively add an extra pane for insulation, stop drafts, etc. and it's perfectly clear like a piece of glass. We did it for years before we could afford to replace our windows, and it makes a huge difference. The kits generally cost less than $10 and they do make ones specifically sized for patio doors.

Use curtains for insulating sliding glass doors. If you can't afford new, go to thrift shops and look for king size comforters and bedspreads. Hang these as window quilts at night.
Purchase Vinyl at Fabric Store
During the winter, we cover our windows and sliding doors with clear vinyl that we bought at a fabric store. The vinyl is clear so you can see through it. Also, the vinyl lasts and lasts.
Cut Insulation Board to Fit
We have a sliding glass door in our kitchen. Hubby cut two pieces of tongue and groove insulation board 1 1/2" thick (1 1/2" thick was what we had around the house) to fit the opening so that it goes inside the frame snug. Then we got a sliding door size piece of plastic that had double-sided tape to stick it on the frame around the door. We used a hair dryer to get rid of all the wrinkles. It worked wonderful. We pulled the drape over it for extra insulation and to cover it so that no one sees what we did. It works really well. Don't forget to save the insulation board for the next year.
Insulating Sliding Glass Doors with Shower Curtains
Hanging a heavy duty clear plastic shower curtain liner with clear plastic dollar store hooks on a tension rod would definitely help.
