Alright, let’s cut to the chase—if you’ve ever stood in a hardware store, scrolling through window options, and caught side-eye from a friend saying, “Wait, outward-opening ones? Aren’t those easier for burglars?” you’re not alone. As a guy who’s been selling outward opening windows for the last 7 years (yeah, I’m the supplier you might’ve glanced at at a home show or DMs for a “quick quote”), this question hits close to home. I get why people ask it—when you picture a window swinging out, it looks like there’s less to block a quick pry, right? But let’s put the myth to bed with actual facts, not that random Reddit thread your cousin posted at 2 a.m. last Tuesday. Outward Opening Windows

First, let’s do the basic breakdown here: outward opening windows (we call them “casement windows” for the most part, with a few awning-style ones for higher up) are hinged on the side, crank open outward, vs. inward-opening ones that swing into your room. That outward swing is the big talking point for both good and bad—better airflow when it’s pouring rain (hello, no dripping on your couch) but wait, what about security? Let’s start with the fear: people think burglars can reach through the gap, jimmy the latch, or slip a tool between the frame and glass easier. Let’s test that against real security research, not TikTok “break-in hacks.”
I reached out to a contact at the National Locksmith Supply Association (NLSA) last year, and they said something that stuck: 90% of residential break-ins happen through doors, not windows. And of that window-related 10%, 70% are through first-floor windows that are unlocked, not because someone pried a frame apart. That’s a huge number—most of the risk isn’t the window type, it’s user error. Now, does outward opening change that stat? Not really, according to their data. Let’s talk about physical design, because that’s where the rubber meets the road with these windows.
First, the latch system. When I started in this biz, a lot of cheap outward windows had a basic slide latch—total joke. But now, most quality ones have multi-point locking systems. What does that mean? Instead of one little hook on the side, you have latches at the top, bottom, and middle of the window sash that lock into reinforced steel strike plates in the frame. For outward opening windows, these strike plates are outside the sash, right? So to get to them, a burglar would have to jimmy the sash so hard it bends, or somehow reach outside the house to manipulate the lock—wait, if it’s a first-floor window, how? They’d have to be on your lawn, in plain sight, doing that. Compare that to an inward-opening window: the lock is on the inside of the sash, so if someone gets inside your first floor (say, through an unlocked door) they can just reach over and flip the window lock. That’s a scenario I see way more often in my service calls than a burglar prying an outward window open.
Another point: the gap. When an outward window is closed, the gap between the sash and frame is tiny—usually less than a quarter-inch, if it’s installed right. Burglars use tools like crowbars or credit cards, but a credit card’s thickness is way bigger than that. And if a window is pried, outward-opening sashes have a flange (that extra bit of frame that sticks out) that makes it harder to get a tool in there. Inward ones, by contrast, have a gap on the inside edge that’s easier to slip something into. I’ve seen this tested at industry demos—guys with specialty tools struggled 3x longer to pry open a high-quality outward window vs. a mid-tier inward one. That’s not my opinion, that’s a test run by the Window and Door Manufacturers Association (WDMA) back in 2021.
Wait, but what about those top-floor windows? Like, awning-style outward windows that are 10 feet up. People joke that a burglar could climb a ladder and pop that open. But here’s the thing: most people don’t leave their top-floor windows wide open. And even if they leave them cracked, the multi-point lock can be set to “vent” mode—so it’s not fully latched, but it’s not easy to yank open from the outside. Also, ladders are loud, and neighbors usually notice someone with a ladder by a house at 2 a.m. I’ve had maybe 3 service calls in 7 years where a customer said their outward window was tampered with, vs. 18 for inward windows that were left unlocked and someone just lifted the sash up. That’s the actual data from my small, local crew—way more actionable than a study from 20 years ago.
Now, let’s address the counterpoint, because I’m not here to sell you something that’s not true. The only scenario where outward opening windows do have a small security risk is if you get super cheap, no-name ones from a big box store that skip the reinforced frames. I’ve seen those—plastic frames, flimsy latches, strike plates that are just thin aluminum. Those are bad, regardless of type. But that’s not about outward vs. inward, that’s about cheap vs. quality. If you buy a $50 window from a store that doesn’t list WDMA certification, it doesn’t matter if it opens in or out—it’s gonna be easy to break. The same contact at NLSA said that 80% of window-related break-ins involve poorly installed or low-quality windows, not the direction they open. That’s a key line for anyone reading this.
Also, let’s talk about common misconceptions. Some people say, “Well, if a burglar gets the window open, they can climb through easier.” But with inward windows, the entire sash swings into your house, so the opening is the same size as the window. With outward, the sash is on the outside, so the opening is just the frame—you have to reach through the gap, which is tiny, to climb in. I’ve tested this with my buddy who’s a former construction worker—he tried to climb through an outward window that was cracked, and he couldn’t fit his shoulders through without prying it a lot. That’s not a flaw, that’s a security feature.
Wait, and what about fire? Oh, people also mix up security with fire escape. If you have to escape through a window in a fire, outward opening windows swing out, so you don’t have to push against smoke or heat—you just crank them open and push out. Inward ones would push into the room, which might be blocked by furniture or your escape path. That’s a huge safety benefit that people often overlook, and it doesn’t come at a major security cost, because fire escape scenarios are rare, and the security features of the windows still hold up.
Now, let’s get real about real-world use. I installed a set of outward casement windows for a family last year—they had a back deck that’s super exposed, and they were worried about someone climbing up from the ground. We went with our mid-grade line, with reinforced steel frames and multi-point locks. They told me a month later that their neighbor had an inward window on the same back wall get pried open (cheap one from a big box store), but theirs was fine. That’s not a fluke—most of the feedback I get from customers is that outward windows are just as secure, if not more, than inward ones, once you skip the cheap stuff.
I also want to call out the “break-in risk” studies that people cite online. A lot of those are old, from the 90s, when multi-point locks weren’t standard on outward windows. Back then, most outward windows had single latches, so they were easy to pry. But that’s not the case anymore—modern outward windows are engineered with security in mind, not just airflow or curb appeal. The WDMA did a follow-up test in 2022 with current models, and they found that outward windows with proper locks took 2x longer to breach than inward ones with the same lock type. That’s a big shift from 20 years ago.
So, let’s wrap up the facts here, no fluff:
- 90% of break-ins are through doors, not windows, and most window break-ins are unlocked windows, not pried ones.
- High-quality outward opening windows with multi-point locks and reinforced frames are just as secure as inward ones, often more because the lock points are harder to access from the outside.
- Cheap, uncertified windows are a security risk, regardless of opening direction—this has nothing to do with outward vs. inward.
- Outward windows have extra safety benefits for fire escape, which is a big plus for families.
Now, if you’re reading this and wondering if outward opening windows are right for your place, don’t let the old myth hold you back. I’ve been supplying these for years, and I’ve never had a customer come back saying their outward window was the reason someone broke in. What I have heard is complaints about inward windows leaking when it rains (they open into the house, so water seeps in if the seal is off) or being hard to clean (you can reach the outside of an outward window from inside, vs. inward ones that you have to climb a ladder to clean).

If you’re ready to look at options, or just have more questions about security features, lock types, or what size would work best for your home, hit me up. I’m not here to push you into a product that doesn’t fit—just to give you the straight facts, no salesy jargon, just real experience. I’ve got samples, pricing breakdowns, and references from local customers who’ve had these windows for years without any issues. We can chat about security specs, installation tips, whatever you need. Don’t let internet myths make you pick a window that’s not right for your home.
