The $6 IKEA Find That Cools My Room By 5 Degrees During Heat Waves

A $6 IKEA Shade Is the Summer Hack You Didn't Know You Needed

Every summer, the same ritual plays out in apartments and houses across the country: temperatures climb, fans spin uselessly, and fingers hover anxiously over the thermostat. Running central air conditioning or a window unit for hours on end is effective, but the energy bill that follows can feel like a second heat wave hitting your wallet. So when a $6 product from IKEA promises to drop your room temperature by up to 5 degrees Fahrenheit without touching a single dial, it's worth paying very close attention.

The product in question is the IKEA SCHOTTIS blackout shade — a pleated, paper-based window covering that has quietly become one of the most talked-about budget home finds of the season. It requires no tools, no drilling, no landlord permission, and no complicated installation. What it does require is about five minutes of your time and a willingness to rethink what "window treatment" really needs to look like.

What Exactly Is the IKEA SCHOTTIS Shade?

The SCHOTTIS is a temporary blackout pleated shade made from a thick, opaque paper-like material. It comes in a few sizes to fit standard window widths and attaches directly to your window frame using double-sided adhesive strips that are included in the package. There are no brackets to mount, no curtain rods to source, and no hardware store runs required.

Its primary design purpose is to block light — which makes it a popular choice for nurseries, bedrooms, and shift workers who need to sleep during daylight hours. But as renters and homeowners have increasingly discovered, blocking light is also one of the most effective strategies for blocking heat. These two functions, it turns out, go hand in hand in the most satisfying way possible.

The shade pulls down from the top of the window frame and can be adjusted to any height, letting you control how much natural light enters the room at any given time. When fully extended, it creates a near-total blackout effect that also acts as a meaningful thermal barrier against solar heat gain.

Why Blocking Sunlight Cools a Room More Than You'd Think

To understand why such a simple, inexpensive product can have such a noticeable cooling effect, it helps to understand where most of a room's heat actually comes from during the summer. A significant portion — studies suggest as much as 30 percent — of unwanted heat gain in a home enters through windows. Sunlight streaming through glass doesn't just light up a room; it radiates infrared energy directly onto surfaces, floors, furniture, and walls, all of which absorb that energy and slowly release it as heat.

This is why a room with large, south- or west-facing windows can feel noticeably hotter than one with smaller or north-facing openings, even when outdoor temperatures are identical. It's also why drawing a shade or curtain — especially a thick, opaque one — can make such an immediate and measurable difference inside.

The SCHOTTIS shade's blackout material is specifically designed to block the maximum amount of light possible, which means it's also blocking that radiant solar energy from entering in the first place. Less solar energy in equals less heat buildup, which translates directly to a cooler room without running any appliance at all.

How Much Can It Actually Lower the Temperature?

The headline claim — a 5-degree drop — is striking, but it's not an anomaly. Multiple homeowners and renters who have used the SCHOTTIS during heat waves report temperature differences of between 3 and 7 degrees Fahrenheit in rooms where the shades were installed compared to rooms left uncovered. The variance depends on several factors, including window size, sun exposure, whether the shade is used alongside other cooling strategies, and how well-insulated the room is to begin with.

Five degrees might not sound dramatic on paper, but in practice it's the difference between a room that feels stuffy and suffocating and one that feels genuinely livable. It can also mean the difference between an air conditioner running constantly and one that cycles off periodically — a distinction that shows up clearly on your electricity bill at the end of the month.

It's Cheaper Than Every Alternative

To put the value into perspective, consider the alternatives. Cellular or honeycomb shades — widely regarded as one of the most energy-efficient window covering options — typically cost anywhere from $40 to over $200 per window. Blackout curtains with a proper thermal lining run from $30 to $80 for a single panel. Professional window film installation can cost several hundred dollars per room. Even a basic box fan to circulate air costs more than a set of SCHOTTIS shades.

At $6 per shade, outfitting an entire apartment with blackout coverage becomes a genuinely accessible project. A one-bedroom apartment might require five to eight shades to cover its windows fully — a total investment of $30 to $48. For context, that's roughly the cost of running a standard window air conditioner for one or two days, depending on your local electricity rate.

Perfect for Renters and Anyone Who Hates Drilling

One of the most compelling selling points of the SCHOTTIS is its renter-friendly design. Because it mounts with adhesive strips rather than screws or bolts, it leaves no marks on window frames and can be removed at the end of the season without damaging the surface underneath. This makes it ideal for apartment dwellers who can't or don't want to make permanent modifications to their space.

It's also a practical choice for anyone who simply dreads the process of measuring, ordering, and installing more permanent window treatments. The SCHOTTIS can be up and working within minutes, meaning you can respond to a heat wave the same day rather than waiting weeks for a custom order to arrive.

Tips for Getting the Most Out of Your SCHOTTIS Shades

• Install them on east-facing windows before morning sun hits and on west-facing windows ahead of the afternoon peak to intercept heat before it enters the room.

• Combine the shades with a ceiling fan set to run counterclockwise in summer to push cool air downward and circulate the cooler air the shades help preserve.

• Use them in tandem with light-colored curtains or drapes hung in front for an extra layer of insulation and a softer aesthetic finish.

• Keep them fully lowered during the hottest hours of the day — typically between noon and 4 p.m. — and raise them in the evening once outdoor temperatures drop to allow cross-ventilation.

• In rooms where you need some natural light, lower the shade only partially to block direct sun while still letting diffused daylight in from the sides.

A Simple Solution to a Very Expensive Problem

Heat waves are becoming more frequent, more intense, and longer-lasting in many parts of the world. For renters, apartment dwellers, and anyone working with a tight budget, the prospect of managing indoor temperatures without a hefty energy bill can feel genuinely stressful. The IKEA SCHOTTIS blackout shade doesn't solve every problem — it won't replace an air conditioner on a 100-degree day — but it does something arguably more important: it reduces how hard your cooling systems have to work in the first place.

For $6 a window, that's one of the smartest investments you can make before the next heat wave rolls in. Stock up before they sell out — because word has clearly gotten out.
