Single-Cell vs Double-Cell

Single-cell shades have one row of honeycomb cells; double-cell shades stack two smaller rows, trapping more still air. The trade is straightforward: double-cell insulates better and is the pick for drafty windows and extreme climates, while single-cell costs a little less, stacks tighter at the top, and is plenty for temperate rooms. Larger windows carry the deeper double-cell stack without looking heavy. Cell size is a published spec, not marketing, so read it on the product page. Per-window prices put double-cell a modest step above single — worth it where insulation is the job, skippable where it isn’t.
