For a truly dark bedroom, blackout cellular shades or roller shades mounted inside the window frame block more light than curtains alone, because they seal against the frame instead of hanging loose at the sides and bottom. Blackout curtains can get you close, but only when paired with a snug track and side panels wide enough to overlap the wall — on their own they almost always leave a glow around the edges. Many Greater Vancouver bedrooms end up using both: a blind for the seal, curtains for the layered look and extra softness.
Blinds and shades made from blackout fabric are cut to the exact width and height of your window opening, then mounted inside or outside the frame with side channels or close-fitting brackets. That precision is what stops light from sneaking in around the edges. Curtains, even blackout-lined ones, hang from a rod above the window and drape down — there's almost always a gap at the top where the rod sits and along the sides unless the panels are cut extra wide. If your bedroom faces east and morning light is the problem, that gap is exactly where it gets in.
Blackout cellular (honeycomb) shades use a light-blocking fabric bonded into the pleats, plus the cellular structure itself adds a bit of insulating dead air space between panes and the room. For bedrooms we usually recommend:

They can, but only with the right setup. To get close to full blackout with curtains alone you need:
Even with all that, curtains move with drafts and don't seal at the bottom the way a fitted blind does. If total darkness matters for shift work, newborns, or migraines, curtains alone are usually the weaker choice.
Yes, and it's a popular choice for Vancouver bedrooms. A blackout cellular or roller shade mounted inside the frame handles the actual light seal, while curtains on an outside rod add softness, sound dampening, and a finished look. This layered approach also gives you flexibility — sheer curtains during the day with the blind up, blackout shade down at night. It's the setup we recommend most often during a free in-home consultation, since we can measure both the window opening and the wall space around it to get sizing right for each layer.
Blackout fabric on either a blind or curtain adds a small buffer against heat gain in summer and heat loss in winter, since it blocks direct sun and adds a layer of material at the glass. As a rule of thumb, tighter-sealing window coverings like an inside-mounted cellular shade do a better job of reducing drafts than curtains that hang loose, though results vary by window condition and how well the covering fits. For light sleepers, the darker the room, the more consistent your circadian rhythm tends to be — a well-sealed blackout shade is one of the simplest ways to get there without renovating.
Blackout shades wipe down with a dry cloth or vacuum brush attachment and rarely need washing. Curtains, especially blackout-lined ones, need periodic laundering or dry cleaning depending on the fabric, and heavier panels can be a hassle to take down. If low-maintenance is a priority, a blind wins here too — see our guide on cleaning window blinds for the quick routine.
Custom blackout blinds generally cost more upfront than off-the-shelf curtains, but they're built to the exact window and typically last much longer without sagging, fading unevenly, or needing replacement. Pricing varies by width, height, fabric, and whether you choose cordless or motorized lift, so the most accurate way to compare is a free in-home consultation where we measure your actual windows and walk through fabric options side by side.

Rarely on their own. Most blackout curtains block roughly 90-99% of light through the fabric itself, but light still leaks in around the top of the rod and the sides of the panels unless they're cut extra wide and hung close to the wall. A properly fitted blackout blind mounted inside the frame usually seals better.
Yes, especially if you choose a cordless or motorized lift. Corded lifts carry a strangulation risk for young children and pets, so for bedrooms we recommend cordless cellular or roller shades, or Somfy motorized options. Every order also includes free safety cleats.
Yes, this is a common setup. The blackout shade handles full darkness at night, and sheer curtains soften the window and filter light during the day when the shade is raised. It also adds a finished, layered look without sacrificing light control.
They can help reduce heat gain since the fabric blocks direct sun at the glass, and cellular styles add a small insulating air pocket. Results vary by window size and orientation, so pair a blackout cellular shade with good window sealing for the best comfort in a hot bedroom.
