Sunroom Insulation

3 Materials
6 Hours
Wanted to try to use my sunroom well into the winter. It has baseboard heat, but they are not extremely energy efficient. So I came up with these removable panels for the floor level windows.
My sunroom is approximately 180 SF, and it's floor-to-ceiling single pane windowS. I usually use shrink film in the winter, but I wanted something a little more substantial, and I wanted it to look nice.
The foam and the paper cuts easily with a box cutter. Use a straight edge as a guide for both the foam and the paper.
1/4 inch by 4ft x 50 feet. $40 at Lowes. Did one set of panels in my 180SF sunroom with alot Left over!! Can use any kind of insulation panels, these fit in the back of my small SUV. (I did have to slop on a bit of paint over the logo before I covered with contact paper) The "non logo" side faces outside.
Each panel is cut to fit, and covered with wood grain contact paper. (I used 5 rolls at $15 each. I did get one for $7 on a lightning deal, tho... I got these on amazon). The dimensions for the paper 17.7 in X9.8 ft. I had to piece SOME pieces together to avoid waste, but the grain is forgiving and it looks natural unless you are up real close. Then I found some door frame stop for $2 (for 7ft) and made my frames and some slats at the folds. Frames are simple angled cuts and held together with a brad nailer. Spent $14
after making "frames", I had enough left over to cut some "slats" which cover the slightly obvious folds in the foam board.
This is what they look like after all is done. This is the bottom row of Windows. The top row are much smaller and I would have ALMOST enough material to do those also, but I do want to let the sun in.
Another "after" view. Total $$ about $150 with clear plastic window film for the big windows , and the small ones on the top. It has transformed the room and they are removable.... but I may leave them up all year!
Next year, I will only have to buy window film.
Suggested materials:
  • Foam insulation board   (Lowes)
  • Door frame stop   (Menards)
  • Wood grain contact paper   (Amazon)

    Would this work to keep heat out in summer when it is so hot in FL.?

    I have a similar sun room, perhaps now I can use it in the winter!
