Cellular (honeycomb) shades are the strongest window covering choice for cutting heat loss in a Metro Vancouver winter. Their hollow, honeycomb-shaped cells trap a layer of still air right against the glass, which slows the heat transfer that happens through single- and double-pane windows on cold, wet nights. Lined roller shades and layered treatments (blinds plus drapery) come next, while venetian and faux wood blinds offer the least insulation because their slats never form a sealed air layer.
Windows are almost always the weakest point in a home's building envelope. Glass conducts heat far faster than an insulated wall, and in Coquitlam, Vancouver, Burnaby, and other Lower Mainland neighbourhoods with older housing stock, many homes still have single-pane or aging double-pane windows. Our winters aren't brutally cold, but they are long, damp, and grey, which means furnaces and heat pumps run for months at a time. Any heat that escapes through glass has to be replaced, and that adds up over a heating season.
Cellular shades are built from pleated fabric that forms rows of hexagonal pockets when you unroll them. Each pocket holds a pocket of air, and that air acts as a buffer between the cold glass and your warm room. Double-cell versions (two rows of pockets stacked front to back) insulate better than single-cell because there's more trapped air between you and the window. Cellular shades are available in top-down/bottom-up configurations, so you can drop the top of the shade for daylight and privacy while still keeping the insulating layer in place lower down. For north- and west-facing rooms that catch the worst of Vancouver's winter wind, double-cell shades are usually the better pick.
Roller shades with a thicker or room-darkening backing help, though not as much as cellular shades, because a flat fabric panel doesn't create an insulating air pocket the way a honeycomb structure does. What they do offer is a tight, close-to-glass fit that blocks some of the cold air that settles and rolls off a window pane at night. If you already like the clean look of roller shades, choosing a heavier fabric and having them fitted close to the glass will improve their winter performance.
Venetian blinds, faux wood blinds, and California shutters are excellent for light control and moisture resistance, but their horizontal slats leave gaps that air can move through, so they offer the least insulation value of the products we carry. That doesn't rule them out for winter — many BC homeowners choose faux wood blinds or shutters for bathrooms and kitchens where humidity matters more than heat loss, and pair them with drapery in living rooms and bedrooms where warmth is the priority.
Yes. As a rule of thumb, any window covering works best when it's actually closed, since an open or raised shade does nothing to slow heat loss. Closing cellular shades or lined roller shades once the sun goes down, and reopening them in daylight hours to capture any passive solar warmth, is one of the simplest habits that can help a home hold its heat overnight. This matters even more on the classic Vancouver winter night: cold, damp, and windy off the water.
Motorized blinds and shades powered by Somfy can be scheduled to close automatically at dusk and open again in the morning, so you get the benefit of a consistent close-every-night routine without having to remember it yourself. This is especially useful for windows that are hard to reach, like over a staircase or a large picture window, and for households that travel or work late. Explore our motorized blinds and shades if you want winter-ready automation built into your window coverings.
Window coverings are one part of a warmer home, not the whole solution. A few things worth pairing with new blinds or shades:
A home energy audit or a chat with a window covering specialist can help you figure out which rooms need the most attention before winter sets in.
The right mix depends on your windows' age, orientation, and how each room is used. A free in-home consultation lets us measure your windows, check for drafts, and recommend cellular, roller, or layered options room by room, with a Canadian-made, factory-direct product backed by a limited lifetime warranty. Call (604) 942-4201 or book a visit to plan your windows for this winter.
They can help. The honeycomb structure traps air against the glass, which slows heat loss compared to a flat blind or an uncovered window, and the effect is most noticeable in rooms with large or older single-pane windows.
For colder-facing rooms and older windows, double-cell shades generally insulate better because they trap two layers of air instead of one. For milder rooms or budget-conscious projects, single-cell shades still offer more insulation than flat blinds.
Open them on sunny days to let in passive solar warmth, then close them again once the sun goes down or the room starts to cool. This habit gets the most out of any insulating window covering.
Yes. Somfy-powered motorized blinds and shades can be set on a schedule to close at dusk and open at sunrise, so your windows stay insulated overnight without you having to adjust them manually every day.
