Which side of a windshield sun shade faces out?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
The reflective, silver side of a windshield sun shade faces out — toward the glass — so it bounces sunlight back through the window. The darker, fabric side faces into the cabin. The shade goes inside the car, held against the windshield by the sun visors, not outside where wind and rain would carry it off.
How to put a sun shade in a car
The shade fits inside the windshield, not outside it.
- 1
Find the reflective side
The shiny, silver or mirrored surface is the reflective side. That side faces the glass.
- 2
Hold it against the windshield
Press the reflective side toward the glass so the shade covers as much of the windshield as it can.
- 3
Secure it with the visors
Flip both sun visors down over the top edge of the shade to hold it against the glass.
- 4
Fold it to store
To remove it, lift the visors, pull the shade down, and accordion-fold it back into its sleeve so it stays compact.
Reflective side toward the glass
The reflective surface does the work by bouncing sunlight back through the windshield. If you flip the shade so the fabric side faces out, the shade absorbs heat instead of reflecting it and the cabin warms faster.
Tips for a snug fit
- Choose a shade sized to your windshield so it covers the glass edge to edge.
- Tuck any extra material behind the visors so it does not sag away from the glass.
- Store the shade in its sleeve when folded so the reflective surface stays clean.
- Replace a shade that has torn or lost its reflective coating, since it no longer bounces light well.

Which side of the sunshade goes out?
The reflective, silver side faces out toward the glass. That surface bounces sunlight back through the windshield. The fabric side faces into the cabin.
Do sun shades go inside or outside?
Inside. The shade is held against the windshield by the sun visors. Outside it would catch wind and rain and would not stay put.
How do you fold a windshield sun shade?
Lift the visors, pull the shade down, and accordion-fold it along its built-in seams, then slip it into its sleeve. Folding along the seams keeps it compact and stops the reflective surface from creasing.
