Hey everyone, I\u2019m Jake, and I\u2019ve been supplying outward opening windows for residential and commercial projects across the Midwest for the last 8 years. I get this question literally every single week from homeowners, architects, and contractors alike: \u201cAre outward opening windows actually resistant to wind?\u201d Most people I talk to seem to have this knee-jerk thought that because these windows swing outward instead of inside, they\u2019re flimsy or easy to push around during a storm. Let\u2019s cut through the confusion here\u2014no overly technical jargon, just real talk from someone who\u2019s sold, installed, and tested these things through countless wind events. First, let\u2019s get one basic fact straight: outward opening windows (we call them \u201ccasement\u201d and \u201cawning\u201d windows in the trade, fyi\u2014casement swings out like a door, awning tilts out from the top) aren\u2019t just a design choice; their entire structure is built for wind performance. I remember a customer a couple years back in Des Moines who had his old, run-in casement windows replaced with ours right before a Category 2 storm hit. His old ones blew open halfway during the storm and took out a section of his siding\u2014total disaster. The new outward openers? They stayed locked tight, no leaks, no issues. That\u2019s not luck\u2014that\u2019s engineering. The big reason outward opening windows hold up better in wind is their operating mechanism. When a casement window is closed, it\u2019s not sitting on a flimsy latch like a slider window (which basically just slides along a track and can get pushed up by wind pressure). Instead, it\u2019s compressed between two rigid frames\u2014one on the window sash, one on the wall. The wind actually pushes the sash against<\/em> the frame, not away from it. That\u2019s a game-changer. Let\u2019s think about how wind works, too. Wind creates pressure differentials\u2014when it blows hard against a building, the pressure on the outside goes up, so the inside pressure pushes outward. For inward opening windows, that inward sash means wind pressure pushes away<\/em> from the frame, putting stress on the hinges and latches. Outward openers? Wind pushes the sash harder<\/em> into the frame, so the seal is tighter and the load is distributed evenly across the whole frame, not just the hardware. I\u2019ve seen this tested in our own shop\u2014we set up a pressure chamber and pushed outward opening windows with wind speeds equivalent to 150 mph (that\u2019s Category 4 territory) and they held steady. Compare that to a double-hung window we tested at the same time, which started to flex at 110 mph and had a small leak at 125 mph. Now, that said, not all outward opening windows are created equal. I can\u2019t stress that enough. I\u2019ve seen cheap knockoff outward openers from big-box stores that use thin aluminum frames and plastic hardware\u2014those will definitely fail in strong wind. That\u2019s where our product line comes in: we use reinforced vinyl or heavy-gauge aluminum frames, stainless steel hinges, and multi-point locking systems that engage at 3, 4, even 5 points around the sash, not just one latch in the middle. Another thing people ask about is window size. A lot of folks think bigger outward opening windows are more vulnerable, but actually, when sized right, they perform even better than smaller ones. Because the pressure is distributed across the whole sash, a wider casement window has more surface area, but the frame is engineered to match the load. We did a project last year in a coastal town in North Carolina where we installed 6-foot wide awning windows on a beach house, and they survived a nor\u2019easter that had 130 mph gusts. The homeowner sent me a photo later\u2014no damage, not even a scratch on the seal. The only time I\u2019ve seen outward opening windows struggle is when they\u2019re installed incorrectly. If the frame isn\u2019t level, or the flashing is bad, wind can get behind the frame and push it out from the wall. That\u2019s not a flaw in the window\u2014it\u2019s a mistake in the install. I always work with contractors to make sure every window is set right, sealed properly, and the hardware is adjusted so the sash closes evenly all around. What about common myths? I hear a lot that outward opening windows are hard to open during a storm if they\u2019re already wet. Wait, no\u2014wet seals actually help the lock engage tighter, not looser. And if you have a power outage, you can still open them manually, unlike some crank-operated models? No, wait, most casement windows use a hand crank, so even if the power is out, you can crank them open easily\u2014way easier than trying to break open an inward window that\u2019s sealed tight from wind pressure. Another myth: outward opening windows are a safety hazard because they swing out into walkways. Yeah, if you install them above a sidewalk, that\u2019s a problem, but there are solutions\u2014awning windows tilt out from the top so they only stick out a foot or so, and you can choose crank lengths that keep them clear of the path. I personally recommend awning windows for areas close to walkways, casement for higher up or areas with strong prevailing winds. Let\u2019s talk about real-world data, because I know a lot of you want numbers to back this up. The American Architectural Manufacturers Association (AAMA) does wind load testing for all window types, and outward opening windows consistently meet higher residential wind ratings than sliders or double-hungs. For example, our standard outward opening windows meet AAMA 90 mph wind resistance, and our heavy-duty line hits 130 mph\u2014perfect for coastal areas or tornado-prone regions. I\u2019ve had clients in Oklahoma (tornado alley) swap out their inward windows for ours and tell me they feel way more confident when a storm is coming. Now, I\u2019m not saying outward opening windows are perfect. If you have a really narrow, shallow space next to a window, an outward opener might not work for your design. And if you\u2019re on a tight budget and buy the cheapest option, you\u2019ll get the cheapest performance. But if you\u2019re looking for a window that can stand up to regular wind events, from mild breezes to severe storms, outward opening windows are the way to go. One last personal story: my own house here in Ohio has our outward opening casement windows on the back of the house, which faces the wind that comes off Lake Erie. A couple years ago, we had a straight-line wind storm that hit 100 mph. All the sliders on the front of my neighbor\u2019s houses had gaps, rain got in, and one neighbor\u2019s slider even blew open. My windows? They didn\u2019t make a sound. No leaks, no rattles, nothing. That\u2019s why I started selling these windows in the first place\u2014because I saw how well they worked for my family, and I wanted others to have that same peace of mind. If you\u2019re renovating your home or building a new place and you\u2019re worried about wind performance, don\u2019t just go with what the big-box store pushes. Reach out\u2014we can talk about your area\u2019s wind zone, the size of windows you need, and what model will work best for your project. I\u2019ll even send you a copy of our independent wind test results, no strings attached. No guesswork, no sales hype\u2014just real answers from someone who\u2019s been in this game long enough to know what works. And hey, if you have questions, drop a comment below\u2014I\u2019ll respond to every single one. Don\u2019t take my word for it, but take the science, the real-world installs, and the fact that these windows have saved people thousands in storm damage. Outward opening windows aren\u2019t just a trend\u2014they\u2019re a smart choice for anyone who wants their windows to actually do what they\u2019re supposed to do: keep the wind out, the home safe, and the inside quiet, even when the weather gets rough.
