Will these work on the newer style "plastic" windows? Or are they only meant for wood windows?

Yes, they should work on most double hung windows. They fit inside the side jamb where the window slides up and down.

It will work on any windows, is my understanding. Shouldn't make a difference. I installed it on a single pane window. People still comment thinking it is a true stained glass window! Very happy with it!

Yes. We have installed these on 10 VINYL windows in our house and they do prevent the window from being opened too far. The design forces the wedge toward the window and so the stickiness is not an issue.

They work great. Less noise and nice to be able to see out the windows. The plastic we had before got cloudy. These windows are great!

They are mainly designed for wood, the set has multi tooth assortment. You probably can use for plastic, but these are not metal blades

I put mine on a old window with new glass in it. I had to remove and adjust them alittle and there did not seem to be any residue on the glass. They are really beautiful. Good luck

I used one on each, and they worked really well. These were for ground floor windows, at ground level, that open sideways. I set them up, left the velcro to 'set up', then had my brother try to force his was in. He had no luck at all. I feel perfectly safe with them.

Might work in older wood windows. Newer windows usually some type rubber/vinyl seal on the sides. Thus it may make the contact and magnet to far from each other.You might get enough contact to the magnet if you put it in the bottom of the window and the contact in the sill portion.

I don't have double hung windows, so I'm unsure if these will work. It works on locking the bottom slide window from moving up any farther. Hopefully someone with double hung windows will be able to give you a better answer.

I cut it for those very kind of windows and they work very well. I did put a dab of a waterproof glue stick in each corner, but I don't know if that made any difference. Staying up and works well.

Yes. They will work on any smooth, clean, glass surface. These decals work as well on tinted windows as on nontinted windows.

I'm sure they'll work on anything. HOWEVER, ours are less than one year old and a lot of the green paint has flaked off. Because they are over 60 days old, Amazon won't let me exchange them even though they are defective - I'm not trying to return them, I just want new ones. So, I got in touch with OSD directly and it appears that they will stand behind them - I just had to send them some photos and a copy of my Amazon receipt. I may never buy from Amazon again.

These permanently mount to the glass. You theoretically could use them for side windows, but you would not be able to roll the window up and down.

They should work well in this application on smooth surfaces like a plastic fence or plastic siding. On rough surfaces you could add a layer of 3M double sided mounting tape. In the long term they may become brittle outdoors.

I don't know. I only use these on our file folders; and, unfortunately, I don't have anything plastic in the office to try one on. Sorry I couldn't be of more help.

No they are plastic. They work really well! Pay attention to how the old ones are threaded and just do the same.

I'm not sure if it will adhere well to plastic, maybe if you rough up the surface a bit first. They make a special epoxy that is made just for plastic, that might be better in your situation. Enter B00083WZDY in the Amazon search.
