My house was built in the 1950's and still has single panel aluminum sliding windows. The windows are 36x46.These pieces fit my windows exactly.I added a reflective insulated product against the glass and covered that with the cardboard. I used adjustable, tension curtain rods to hold these pieces tight to the glass.It works great - no noticeable drafts or cold spots in any of the 6 windows. My utilities are showing the improvement this DIY has done.

The double corrugation makes these sheets very stiff, so it is easy to move around without them folding up.

The shipping company supposedly damaged these cardboard sheets, but since no replacement was offered, I'm suspicious that the good price indicates an imaginary product.
