Double-Cell vs Single-Cell Cellular Shades

The call

Double-cell is the pick for drafty or extreme-climate windows — the extra trapped air measurably improves the insulation the whole category sells on, and larger windows carry the deeper stack without looking heavy. Single-cell costs less, stacks tighter at the top, and is plenty for temperate rooms and smaller windows. Cell size is a real spec, not marketing: read it on the product page. Per-window prices quoted at analysis put double-cell a modest step above single. Confirm the inside-mount depth (cellular needs roughly 3/4") and the deduction against the seller’s guide before ordering.
