Hey all! My name is Julia, former college student and a home decor enthusiast who loves DIY home improvement projects and finding creative ways to decorate any living spaces on a budget. Recently moved from my dorm to my new apartment which I renovated from scratch and I am here to help you with tips & tricks about home decor/college and more 🙂

Black curtains can add a touch of elegance to any room, but you might be wondering if they also make it hotter. Let’s explore how the color and material of your curtains can affect the temperature in your space.

Do Black Curtains Make Room Hotter?

You might wonder if black curtains make a room hotter, especially during those blazing summer months.

Think about the times you’ve walked past a sunny window and felt the heat pouring in.

Black curtains can actually absorb more heat, potentially making a room warmer if they’re not the right type.

That doesn’t mean you have to toss out any dark curtains you own.

Different styles, like blackout curtains, often help by blocking sunlight and reducing heat if used correctly.

It’s all about picking the right curtain for your space, which can actually keep your room cooler than you might expect.

If you want to dive deeper into how curtains affect room temperature or are just looking for tips on managing indoor heat, stick around.

We’ve got some interesting insights to explore that will help you make the most of your window treatments.

How Curtains Affect Indoor Climate

Curtains are like a barrier between the outside world and your home.

In the summer, they can block out the sunlight that makes your room hot.

This is especially true for blackout curtains, which can stop heat from coming in and keep rooms cooler.

During winter, these curtains can work the other way.

They help trap the warm air inside, which means you don’t have to crank up your heater as much. This can save some money on your energy bills.

Black Curtains vs. Light-Colored Curtains

Do Black Curtains Make Room Hotter?

Choosing the right color can really change how a curtain works.

Black curtains can absorb more heat from sunlight. This might make them a better choice for keeping out winter cold, acting as a cozy blanket for your windows.

On the other hand, light-colored curtains reflect sunlight. This makes them better for summer when you want to keep your room cool.

Blackout curtains, in particular, can do both—keeping rooms warm in winter and cool in summer. They help in reducing heat gain, especially when made with thick materials.

Fabric Types and Thermal Insulation

The kind of fabric used in black curtains matters a lot.

Blackout curtains, for example, are designed to block light and reduce heat.

They often use a tightly woven fabric that keeps sunlight from entering your room. This feature can help you save on energy costs, especially in the summer.

Some materials, like velvet or heavy polyester, are good at insulation. They can stop heat from escaping during the winter, ensuring your room stays cozy.

But be careful, because these fabrics can also trap heat in the summer if not managed properly.

Lightweight fabrics, such as cotton, might not be as effective at blocking heat, but they can work well if combined with a thermal liner.

The liner helps in keeping the hot air out and the cool air in. This combination allows for more flexibility in managing the room temperature throughout the year.

Design Features That Influence Heat Retention

The design of your black curtains affects how much heat they retain. Curtains with multiple layers can provide better insulation compared to single-layer designs.

Thermal linings are a great addition, as they create an extra barrier against heat.

Look for curtains with a tight weave. It helps in blocking out light and heat effectively.

The way you hang your curtains also matters. Hanging them close to the window can reduce the gap through which heat can escape in winter or enter in summer.

Grommet tops or other easy-to-slide designs can make it simple to adjust how much sunlight you want to block out at any given time.

Room Orientation and Sunlight Exposure

The direction your room faces impacts how much sunlight it gets. Rooms facing east or west tend to get more sun during the day, which can make them hotter. In these cases, the right curtains can help manage this heat.

Black curtains, while typically good at blocking light, can also absorb heat. This means if your room faces lots of direct sunlight, those curtains might add to the warmth.

Instead, consider lighter-colored blackout curtains that still block light but absorb less heat.

Think about the time of day you use the room most.

Morning sun is different from afternoon sun, so your curtain choice may vary depending on when you need the room to stay cool.

Window Types and the Importance of Air Vents

The type of windows in your room can change how well curtains work. Single-pane windows let a lot of heat in and out, while double-pane ones help insulate better.

This means with double-pane windows, any insulating curtains like blackout or thermal curtains can be more effective at keeping your room comfortable.

Don’t forget about air vents. If your room has vents, make sure they are not blocked by curtains or furniture.

Airflow can greatly affect how warm or cool a room stays. Proper airflow from vents ensures your room remains balanced and helps the curtains do their job better at managing temperature.

Strategies for Enhancing Air Flow

To keep your home breezy, it’s important to make the most of natural ventilation.

Opening windows on opposite sides of a room can create cross-ventilation. This lets fresh air in and pushes hot air out.

Using fans is another great way to boost air flow.

Ceiling fans are fantastic for circulating air, making a room feel cooler.

If you position a box fan facing out of a window, it can draw hot air out effectively.

Don’t forget portable fans either, as they’re easy to move from room to room.

Keeping your doors open inside your home also improves air flow between rooms.

Ensuring that vents and airways are not blocked is also key. Move any furniture, curtains, or objects that might stifle this flow.

Complementary Cooling Solutions

Aside from enhancing airflow, you can use gadgets and strategies to cooling down.

An air conditioner is a reliable choice. Window units or portable air conditioners can make a big difference, especially during those really hot days.

In addition, thermal or blackout curtains can be useful for keeping the sun’s heat out.

Make sure to choose lighter colors that repel heat, as dark curtains might make it hotter.

Using a dehumidifier can also help, especially because humid air often feels warmer. Removing moisture helps your body cool down more effectively.

Benefits of Blackout Curtains for Privacy

When you’re thinking about privacy, black curtains are a real winner. They are made from dense fabric that keeps people from seeing inside.

This is great if you live in a busy area with neighbors or passersby. You can just close your curtains, and you have a private space that’s all yours.

With these curtains, you don’t have to worry about the shadows or silhouettes that might be visible outside with regular curtains.

Blackout curtains are designed to offer a solid visual barrier.

This is crucial at night when the lights are on inside, making them a perfect choice for bedrooms or living rooms.

Balancing Light Control and Room Temperature

Black curtains can help you adjust how much light comes into your room during the day.

They’re especially useful if you like to watch movies in the dark or sleep late without being bothered by the sun. You just pull them shut, and you’re good to go.

However, there’s a bit of a trade-off. While they block out light effectively, they might also trap heat.

This can make the room warmer than you’d like, especially during hot months.

It might take some experimenting to find a balance between keeping light out and maintaining a comfortable room temperature.

Consider pairing them with lighter-colored thermal curtains for added temperature control.

Frequently Asked Questions

How do different colored curtains affect room temperature?

Dark curtains, like black, can soak in heat from sunlight.

This can make a room hotter during the day because the curtains hold and release warmth inside.

Lighter colors reflect sunlight better and can help keep your space cooler.

Can blackout curtains help in retaining heat during winter?

Yes, blackout curtains can help keep your room warm in the winter.

They act as a barrier, blocking out cold air and keeping heat inside.

This means you use less energy to heat your home, which is good for both comfort and your energy bill.

What are some potential downsides to choosing black curtains for my home?

While they might be stylish, black curtains can make rooms hotter if they get a lot of sun.

They may trap more heat compared to lighter options.

This can lead to increased air conditioning costs during warmer months.

OUR STORY SO FAR IN 20 📸 Besties… can we just tak OUR STORY SO FAR IN 20 📸

Besties… can we just take a moment?! Our little journey to this point — captured in 20 tiny shots (TWENTY!!) — and I’m literally sitting here like… who even am I right now? The way every single step feels like a whole chapter from a rom-com makeover montage?! I can’t even. 🙈

I mean… the excitement?? The TEARS?? (Yes, real ones. Streaming. Down. My. Face.) As I write this, my heart is doing cartwheels and my brain is like: girl, breathe! ❤️

And honestly, I cannot wait — LIKE, CANNOT — to make a full post about the entire process (every high, every low, every “wait, what are we even doing?” moment), and of course… THE FINISHED HOUSE. (Manifesting this reveal, okay?? ✨)

#newhome #newhouse #newchapter
So apparently you can fall in love with a house th So apparently you can fall in love with a house that doesn’t even have walls yet..... is that a thing or just me? 😂

(concrete floors / muddy footprints / pipes sticking out of nowhere)
It’s giving: 30% chaos, 30% rain, 40% “trust the process”.

I walk through the entrance like “ok, future me, remember this” - the half bath that is just pipes, the laundry that’s still a puzzle, the pantry door where groceries will sneak in, the living room that already feels like movie night even though it’s basically a skeleton.

Then there’s the terrace view. You step out and suddenly all the noise, dirt, rain = background. Hills, trees, sky...... kind of looks like a desktop wallpaper that hasn’t fully loaded yet but I’m obsessed.

Upstairs via LADDER (gym membership who?) to bedroom / office / bedroom combo. One room for sleep, one room for work, one room for views that are honestly doing 90% of the emotional support right now.

(save this for the “before” / next time we’ll hopefully have stairs and less mud) 💭🏡✨

Second floor - DONE! ✅ I can’t even begin to tell Second floor - DONE! ✅

I can’t even begin to tell you how giddy I am right now (bursting-at-the-seams kind of excited, you know?). The moment is finally here and I get to share it with YOU my ride-or-dies! ☀️

First of all... can we talk about how the house is finally starting to look like an actual house?! (Like, is this real life or am I manifesting too hard?) And second — THE VIEW. OMG. The kind of view that makes you go “okayyyy, the wait was WORTH IT.” 📸🛠️

And yes, we kept going through the doom-and-gloom weather and the monsoon-level rain because... what’s that saying? When it rains, it pours — but make it aesthetic,right?!(Honestly, who do we think we are?) 🪜

So stay tuned, besties... the transformation era is just getting started. ✨

#newhome #newchapter #newadventure
Babes, my hands are literally shaking (from excite Babes, my hands are literally shaking (from excitement… and maybe too much coffee, who knows?). 😅 I can’t even — the first floor of our house is DONE!!! Like, DONE done. Everything’s moving so fast I swear my brain can’t keep up (is this what adulting feels like?).

Two days ago we had nothing but an empty foundation, and now? All the rooms are just… THERE. Magic?? Nope — just the dream team working faster than I can say “where did my Virgo perfectionism go?” 👀

They were so quick and organized that even I — yes, Miss Overplanner 101 — was impressed. In just a few hours the house started sprouting like a mushroom (in the best way possible 🍄✨).

I’m honestly screaming — can’t wait to see what’s next. (Walls? Windows? My Pinterest board finally coming to life???) Stay tuned, because this is getting REAL. 🏡💖
We’re BACK in the game (like, for real this time 💃 We’re BACK in the game (like, for real this time 💃). The next brigade showed up looking all fresh, fired up, and ready to slay! ☕🔥 We literally started by lifting the house (yes, you heard that right — the HOUSE 😳), and from there it’s been non-stop thrills on thrills.

Everything’s picking up pace, the vibes are ✨ immaculate ✨, and honestly? It feels like something BIG is coming (manifesting it, okay?). So buckle up, grab your iced coffee, and stay tuned — this week’s about to be a wild ride. 💖🏗️👀
