The Complete Guide to Blackout Curtains
The Dark Room That Doesn’t Feel Like One
Full darkness, full style. Here’s how to get both.
Introduction
Walk into a room with well-chosen curtains, and you feel it right away. There’s a completeness to the space that bare windows, or even perfectly installed blinds, can’t fully replicate on their own. Drapery gives a room weight, warmth, and a sense that someone made deliberate choices about it.
Blackout curtains do all of that and block the light.
If you’ve already read our guide to blackout blinds, you’ll know that hard treatments like roller shades and cellular shades are excellent at doing the functional work of light control. Blackout curtains are a different category entirely. They’re soft treatments: fabric panels that hang from a rod, drape to the floor, and bring a layer of design to a space that blinds alone rarely achieve.
The best bedrooms, nurseries, and media rooms in Ontario homes typically have both. This article is about understanding the curtain side of that equation.
What Are Blackout Curtains, Exactly?
Blackout curtains are lined fabric panels designed to block or dramatically reduce incoming light. The keyword is “lined.” A curtain panel on its own, regardless of how heavy the face fabric is, rarely blocks light effectively. What makes a curtain blackout is what’s sewn or bonded to the back of it.
There are three levels of lining commonly found in the market:
- Light filtering lining: adds body and some privacy, but lets significant light through. Not blackout.
- Room darkening lining: blocks most light but allows some to pass through the weave or at the edges. Better than nothing, but not truly blackout.
- Blackout lining: a tightly woven or foam-backed fabric that blocks virtually all light transmission through the panel itself. This is the standard to look for.
Just as with blackout blinds, the lining handles the material performance. The installation (how wide the panels are, how far the rod extends past the window, how close to the ceiling the rod is mounted) determines whether the room actually gets dark.
The Benefits Beyond Darkness
Blackout curtains are often discussed purely on the sleep angle, and it’s true that research shows even low levels of ambient light can affect melatonin production and reduce sleep quality. But a well-chosen blackout curtain does several other things worth knowing about.
Thermal Performance
Lined drapery is one of the more effective tools for managing heat loss and solar gain through windows. Medium-colored draperies with white-backed linings can reduce heat gain through windows by up to 33% in summer. During cold weather, conventional draperies can reduce heat loss from a room by up to 10%. In Ontario, where heating season runs for a significant portion of the year, that’s a meaningful contribution to both comfort and energy bills.
Heavier blackout curtains with thermal lining perform even better than standard lined drapery on this front.
Sound Dampening
A secondary benefit that most people don’t think about until they experience it. Heavy fabric panels absorb sound in a way that hard treatments simply cannot. In urban bedrooms in Toronto, Mississauga, or Hamilton, where street noise is a constant factor, blackout curtains with substantial weight to the fabric make a noticeable difference to how quiet a room feels.
UV Protection
Sunlight that comes through unprotected windows doesn’t just brighten a room. Over time, it fades furniture, flooring, artwork, and textiles. Blackout curtains, when closed during peak sunlight hours, act as a barrier against UV degradation. For rooms with valuable furniture or hardwood floors, this is a real and practical benefit.
Privacy
Floor-to-ceiling blackout curtains, properly installed, provide complete visual privacy from the outside. Unlike sheer or light-filtering treatments, there’s no question of whether someone on the street can see in. This matters particularly in ground-floor rooms and street-facing bedrooms.
Lining Types: What to Look For
Not all blackout linings are equal. Here’s what you’ll encounter:
Standard Blackout Lining
A tightly woven white or cream fabric, bonded or sewn to the back of the face fabric. This is the most common and most accessible blackout option. It blocks light effectively through the fabric panel, though light can still enter at the edges depending on how the curtain is hung.
Thermal Lining
A heavier version of blackout lining, often with an additional foam or metallic layer. Thermal lining adds insulation on top of light blocking, making it particularly well-suited to Ontario bedrooms that deal with cold winters and hot, sunny summers in equal measure. If energy performance matters alongside darkness, thermal lining is worth the upgrade.
Interlining
An additional layer of soft wadding is sewn between the face fabric and the lining. Interlining adds body, improves drape, enhances insulation, and contributes to a richer, more substantial look and feel. It’s common in high-end custom drapery and produces a noticeably different weight and presence compared to standard lined panels.
Fabric and Style Options
Here’s where blackout curtains begin to differ significantly from hard treatments. The fabric choice affects not just how the curtain looks but how it performs, how it drapes, and how much of the room’s character it shapes.
Velvet
One of the most naturally effective fabrics for light blocking and sound absorption. Velvet is heavy, dense, and absorbs both light and noise. Visually, it creates a warm, rich atmosphere. It’s a strong choice for bedrooms, home theatres, and living rooms where you want both function and presence.
Linen and Cotton Blends
A softer, more casual choice. Linen and cotton face fabrics have a natural texture that suits relaxed, organic interiors. With a blackout lining sewn in, they can perform just as well as heavier fabrics while maintaining an airy, natural appearance. Popular in cottage-style homes and bedrooms that lean toward a lighter, more organic aesthetic.
Polyester and Synthetic Fabrics
The most practical and widely available option. Modern synthetic blackout curtains are easier to maintain, resistant to fading, and available in a wide range of colours and textures. A sensible choice for children’s rooms, nurseries, and spaces where durability and easy care matter as much as aesthetics.
Heading Styles
How a curtain is gathered or hung at the top affects both the look and the function. Three heading styles are most relevant for blackout drapery in Ontario homes:
- Pinch pleat: fabric gathered into structured pleats at the top. Creates a full, formal look and works well for bedrooms and living rooms with a classic or transitional aesthetic.
- Wave/ripple fold: a clean, continuous fold that produces a uniform wave across the panel. Popular in high-end residential design and very well suited to motorized drapery tracks.
Blackout Curtains vs. Blackout Blinds: Which Do You Need?
Both. In most cases, the honest answer is both.
Blackout blinds (roller shades, cellular shades) do the technical work of blocking light. They sit close to the window, mount to the frame or wall, and address the problem directly. They are the workhorses.
Blackout curtains bring the design. They soften the room’s architecture, add texture and colour, create a sense of warmth and enclosure, and contribute to how the space feels. They also add an extra layer of light control at the edges of the window.
Together, the two are the standard approach in well-designed bedrooms. The shade handles the function, the curtain handles the room.
If you’re working with a budget and have to choose one, the blind is the better first step for pure light control. Add the curtains when the room is ready for them.
Getting the Installation Right
The installation details matter as much for curtains as they do for hard treatments.
Rod placement: Mount the rod as close to the ceiling as possible, or use a ceiling-mounted track. The less wall visible between the top of the curtain and the ceiling, the better the room feels and the less light enters from above.
Rod width: Extend the rod well beyond each side of the window frame, typically 15 to 30 centimetres on each side. This allows the curtain panels to stack off the window entirely when open, keeping the full window unobstructed during the day.
Panel width: Blackout curtains need to be full enough to close with overlap at the centre and cover the window without gaps. Under-wide panels that barely cover the window look flat and let light in at the sides.
Length: For bedrooms and formal spaces, curtains that puddle slightly or just skim the floor create the most finished look. A clean break at the floor is also appropriate, particularly in rooms with pets or heavy foot traffic.
These details are the difference between curtains that work and curtains that look like an afterthought.
Working With a Specialist
Custom blackout curtains, chosen with the room’s proportions and light exposure in mind and installed correctly, perform in a way that off-the-shelf panels rarely match. Fabric selection, lining choice, heading style, rod placement, and panel width all interact in ways that are easier to get right with professional guidance.
At Alleen & Salnek’s seven showrooms across Ontario, you can see fabrics in person, understand how different linings behave in real light conditions, and work through the details with someone who knows what actually works. The difference between a curtain that was thought through and one that was simply hung is visible the moment you walk into the room.
FAQs about Blackout Curtains
The lining of a proper blackout curtain blocks virtually all light through the fabric itself. Whether the room gets fully dark depends on the installation: how far the rod extends past the window frame, how close to the ceiling the curtains are mounted, and whether there's overlap at the centre. A well-installed blackout curtain on a properly sized rod blocks the vast majority of light. Pairing them with a blackout roller shade or cellular shade underneath eliminates almost everything that remains.
Yes. Draperies with white-backed linings can reduce heat gain by up to 33% in summer and heat loss by up to 10% in cold weather. Thermal-lined blackout curtains perform even better. Keeping them closed on south and west-facing windows during peak sun hours in an Ontario summer makes a measurable difference to indoor temperature.
Significantly more than hard treatments do. Heavy fabric panels absorb sound in a way that roller shades and cellular shades cannot. The denser the fabric and the heavier the lining, the more effective the sound dampening. Velvet is particularly effective at this.
Thermal refers to the lining. A thermal curtain uses an insulating layer, often foam-backed or metallic, designed specifically to improve energy performance. Blackout refers to light blocking. Many curtains combine both: a blackout-plus-thermal lining that handles darkness and insulation simultaneously. When shopping, look for both descriptors if you need both functions.
Yes, and it's a particularly useful upgrade for bedrooms. Motorized drapery tracks allow you to open and close curtains from your phone, a remote, or a voice assistant. Wave-fold heading styles are especially well-suited to motorized tracks. Ask about motorized drapery options when you visit a showroom.
It depends on the fabric and lining. Many synthetic and polyester blackout curtains can be machine-washed on a gentle cycle. Velvet panels, interlining, and custom fabric treatments typically require dry cleaning. Always check the care label, and when in doubt, dry cleaning is the safer option for preserving both the lining's integrity and the face fabric's appearance.
