About this item

  • GREAT QUALITY SCREEN! Tired of buying a window screen frame, window net screen, or window screen mesh that falls apart almost immediately? We have heard the cries for a better product and have delivered with Fenestrelle Expandable Window Screens! Our adjustable window screens are designed for double-hung windows and are even useful as a window screen replacement.
  • ENJOY THE BREEZE! Fenestrelle Sliding Window Screens allow fresh air and gentle breezes in while keeping mosquitoes, bugs, and other insects out. Our window screens feature a white, powder-coated aluminum box frame and fiberglass screen that hold up to the harshest of conditions. Weatherstripping on the top and bottom adjust to rough surfaces. Faster and cheaper than fitting permanent window screens, our window screens give you a durable and attractive choice that also works great with cats!
  • EASY TO INSTALL! Simply open your window and inset the Fenestrelle Window Screen. Expand it to fit the width of the window. Finally, close the window until it contacts the top of the screen. To change the orientation, find and remove the set screws from the frame channel. Slide the two screen panels apart and reinsert the guide pieces into the opposite frame channel. Close the screen, reinsert the set screws and you are good to go.
  • MULTIPLE SIZES! Our Fenestrelle Window Screens comes in several different sizes to fit windows of all sized. Check out the Fenestrelle Brand Store to find a size that is perfect for you!

Does exactly as I need it to ; it keeps the bugs out and lets me have much needed fresh air! I have heavy hung windows that close vertically and there's no net to keep out bugs and small animals but this product has done the trick. This screen is strong enough to hold my hung window open and I have not had any issues.

Does exactly what it's supposed to do. There was a small gap on top I wiggled it around and got that flush. I don't know if it's just my old window or if it does it with others, it looks like there is a small gap on the bottom. Pushing on it seems sturdy. I bought this one specifically because my window doesn't stay open on its own so this is great. Most critique is I wish they had a single option instead of buying two.

Having moved into a first floor apartment in a Victorian house recently, which I now share with my indoor cat, I was desperate, with the warmer weather coming for some air flow for her and me, while keeping her safe. Result!! Hurrah for such a clever, no fuss, easy to install piece of kit. I’ve just ordered more!

I wasn't sure I'd like these since they have to be set in place each time you use them but these have been way better than expected. My rental house doesn't have screens but I want the fresh air! With cats in the house, I was nervous if these would be strong enough for me to feel comfortable with the cats leaning against them or pawing at them.The extension is super convenient. In my photos you can see a large window with my cat, the screen is extended greatly to fit across the whole thing. It easily slides along its built in track to extend to the right size. It also fits in the smaller bedroom windows just fine. The only windows it doesn't fit in my house are skinny bay windows.Just place it in the frame of the window, and close the pane down on top of it. It pinches it in place securely within the tracks. I feel comfortable enough to leave it open all day with no concern that my cats could somehow push it out of place. I've been using it for several months now and they're not showing any wear or damage. The only thing I've noticed is that due to my very dusty desert climate, the tracks have gotten rougher over time and it's less easy to slide it open and closed with one hand.

I have window screens, but also cats that like to stand on them and I lived in fear that they’d push the screen out and take off. I bought these for their 4 favorite windows, so now they’re double-screened and I worry no more! They slide open/closed and are very well-made. HIGHLY RECOMMEND!

These window screens are just perfect for what I needed and so easy to use. I wish they were available in more sizes as I would have bought more.

We bought these because our cat likes to sit in an open window, but I didn't trust the flimsy screens in the big windows of our old house to be sturdy enough to prevent her from falling. As a result we could only crack our windows open an inch or two when the weather was nice.I got these 15" inserts and they work great! They seat into the tracks of the window which makes them feel very sturdy - I can press quite a bit on them and they don't budge, even moreso once the window is closed down on top of them. I don't worry at all now if our cat were to lean a bit of her weight on it, and it feels safer knowing these are acting as a "first line of defense."Luckily our cat doesn't try to escape windows, climb them, or claw at them, so I can't speak to the durability there. The screens do feel a bit thin so I imagine a determined cat could slice through them.They're very easy to take in an out and they work just fine for what we needed them for.

My cat loves sitting in front of an open window. A couple of times she has seen birds, or a squirrel and lunged toward the screen of my window, and I noticed that she had started putting little holes in the screen, and I was afraid that eventually she could shred the screen and claw her way out of the house. I have a two-story house, so the second story escape would cause a lot of injury to her, and eventually, I would have to purchase new screens for the windows. So I purchased a couple of these little removable screens, and they sit right in the windowsill, and I bring the upper part of the window down and secure them. So it gives a layer of protection between my cat and the regular screen and the outdoors. These are very well-made, they are width adjustable, and the screen on them is very strong and durable. I feel much better about her, sitting by the window, and since I have installed these, she has not lunged or clawed toward the screen either. I am very happy with my purchase, and it seems to have solved the problem I was experiencing with her. Like I said, they are very well-made, heavy duty, and the screen is not thin or flimsy. I am so happy I discovered these, not to mention the extra layer of security/safety for my cat.
