A Note from the Studio
The honeycomb cell is one of those rare designs where the engineering is the aesthetic. Air, held still in a hexagon, doing quiet work against the glass. We recommend double-cell for most of San Diego — not because it costs more, but because west-facing glass here earns it. — The iL Progetto Studio, San Diego
Cellular Shades — Frequently Asked Questions
What is the difference between single, double, and triple cell honeycomb shades?
The cell count refers to the number of air pockets stacked in the fabric cross-section. Single-cell shades have one honeycomb layer — affordable and effective for light control. Double-cell shades trap two layers of air and offer significantly better thermal and sound insulation. Triple-cell shades add a third layer for maximum energy performance — our recommendation for rooms with single-pane glass or extreme sun exposure. Most San Diego homes benefit most from double-cell.
How much energy do cellular shades actually save?
The U.S. Department of Energy estimates that cellular shades can reduce window heat gain and loss by up to 40%, depending on cell count, fabric opacity, and mounting. In San Diego, where air conditioning accounts for a significant share of utility bills, properly fitted double-cell shades on west-facing windows can meaningfully reduce cooling costs — especially in summer.
What is top-down/bottom-up operation?
Top-down/bottom-up (TDBU) shades can be operated from either the top or the bottom of the window independently. Lower the shade from the top to let in sky light from above while keeping the lower portion private. Raise the shade from the bottom to let light in from below while blocking the view at eye level. This is particularly useful in bathrooms, street-facing bedrooms, and any room where you want light and privacy simultaneously.
Are cellular shades good for noise reduction?
Yes — cellular shades are the best-performing window treatment for sound dampening, though they are not soundproofing. The honeycomb air cells absorb and dampen high-frequency sound transmission through the glass. Double and triple cell configurations offer noticeably better acoustic performance than single-cell. Customers in homes near roads or with active households in adjacent rooms frequently notice the difference.
