Cellular honeycomb shades insulate by trapping air inside rows of honeycomb-shaped pockets that run the height of the shade. That trapped air acts as a buffer between your window glass and the room, slowing the transfer of heat in both directions. In practice, that means fewer cold drafts near the glass in a Vancouver winter and less radiant heat pushing into the room in summer. They work best on windows that lose or gain the most heat: large single-pane or older double-pane windows, north- and west-facing rooms, and bedrooms or living rooms where you spend the most time near the glass.
Unlike a flat fabric roller shade, cellular shades are built from pleated fabric folded into a row of connected cells, each shaped like a honeycomb when viewed from the side. Each cell holds a pocket of still air against the window. Still air is a poor conductor of heat, so it slows down the natural flow of warm air toward a cold window pane in winter, and blocks some of the sun's radiant heat from reaching the room in summer. The more air pockets between the glass and your living space, the more that heat transfer gets interrupted.
Cellular shades come in single-cell and double-cell builds, and the difference is exactly what it sounds like:
Double cell is generally the better pick for the coldest-feeling room in the house or a window wall that catches full afternoon sun. Single cell is a solid, budget-friendlier choice for rooms where insulation matters less than light control or style.
Any window benefits from a cellular shade, but a few rooms get the most out of the insulating effect:
Yes — BC's mix of cool, damp winters and warm, sun-heavy summer afternoons is a good match for cellular shades. In winter, the trapped air pockets help reduce the chilly draft that settles near single-pane and older double-pane windows common in Lower Mainland homes. In summer, the same air buffer can help slow heat gain on west-facing rooms that catch late-day sun. As always, results vary by window size, glazing, orientation, and how consistently the shades are closed — cellular shades can help reduce heat loss and gain, but they're one part of a well-insulated home, not a replacement for good windows.
Insulation is the headline feature, but cellular shades bring a few other practical advantages worth knowing about:
All of our cellular shades can be ordered in single or double cell, with top-down/bottom-up and motorized options powered by Somfy for anyone building out a smart home setup.
Cellular shades aren't ideal for every window. In bathrooms and other high-humidity rooms, moisture can affect fabric shades over time — faux wood blinds or a moisture-resistant option are usually the better call there. On very wide sliding or patio doors, a cellular shade can work but a vertical cellular or panel-track option is often easier to operate day to day. If your main goal is heat reduction on a large glass wall in direct summer sun, it's worth comparing cellular shades against other shading options for that specific window before you commit.
Because the right cell size, fabric, and lift option depends on your exact windows and how the room is used, the most reliable way to get it right is a free in-home consultation. Our team measures your windows, walks you through single vs double cell for your specific rooms, and gives you a firm quote — call (604) 942-4201, book online, or browse ready-to-order options at /shop.
Cellular shades can help reduce heat loss in winter and heat gain in summer by adding an insulating air buffer at the window, which may help ease the load on your heating and cooling. Actual savings vary by window size, orientation, glazing, and how often the shades are closed, so we avoid promising a specific dollar or percentage figure.
Double cell is generally the stronger choice for the coldest-feeling room in the house or a large window wall, since the extra row of air pockets adds a thicker insulating buffer. Single cell still helps over a bare window and costs less, so it's a fine choice for rooms where insulation is a secondary priority.
Yes, when you choose cordless or motorized lift options, which we recommend for any home with young children or pets. Motorized cellular shades powered by Somfy remove cords entirely, and we include free safety cleats with corded orders as an added precaution.
Standard cellular shades can be built for wide windows, but vertical cellular or panel-style options are often easier to operate on sliding and patio doors. A free in-home consultation is the best way to confirm which configuration fits your specific opening.
