We have vinyl windows in our home.
I'm interested in storm windows for some of those windows.
The home is about 16 years old.
I talked with Lowe's and the company that makes storm windows for them.
They said the existing vinyl windows would be an issue.
Because the storm windows are attached by screws to the existing windows.
And they thought putting screws in the vinyl would be a bad idea.

I don't know what brand windows these are.
They do have something on the outside, however, that makes me think they were designed for a storm window. There are two brackets at the bottom of each window. I'll attach a picture of the bracket and one of our windows. It looks to me like a storm window was designed to sit in these brackets. And then maybe 'clamp' onto the top of the window? fwiw, every home in my subdivision appears to have this same bracket on the window.

Well, any thoughts are appreciated.


(It appears that my picture of the bracket got rotated when I uploaded it. The bracket sits horizontally as seen in the picture of the entire window.)

If your windows are double pane, then adding storm windows could adversely affect their insulating value, and warp the vinyl framing due to heat. Decide, too what the cost is of the storms versus just replacing the entire window (if it is single pane) with a more modern one with LoE 366. It will keep the weather at bay much better than just adding storms.

I know sometimes get cranky when their "question is questioned" , but why do you want storms ? The insulation gain will almost never justify the cost .

The best use for storm windows (IMO) is if you have a wind load situation that is causing problems .

dd57chevy - no crankiness here. It's a good question.
One reason only - summer heat gain.
We live in mid-Missouri. Looks like a bit south of you.
The summers here have become absolutely blistering.
I'm thinking that trend is not going to improve.

Couple of reasons I'd be willing to experiment with a storm window:
1. We've replaced some of the other windows in the house with very premium windows. I honestly don't think they made a huge difference in energy efficiency.
2. This winter we had a week or so of fairly cold temperatures. So I put one of those window film packages on the inside of the window. (You can actually see it in the picture.) That made a tremendous amount of difference. I'm actually thinking of trying one on the outside this summer.

This particular window faces due east.
There is a really nice view out of this window.
I'm open to any suggestions.
Thanks for the interest.

Just throwing some random things at you , not claiming to have the final answer OR trying to offend :

Unless you have high performance reflective glass (as in high dollar commercial glazing) white window blinds are your friend .

IMO , hands down , the best device to keep your house cool are properly placed decidious trees.....planted 30 years ago . :biggrin2:
You should still plant them (with a plan) .
Ditto foundation & other plantings . A bare (& cut short) lawn reflects heat toward your house .

I'd check attic ventilation & AC performance .

Sorry , but IMO , storm windows aren't your answer , here .

Not recommended by vinyl window maker.

You might get away with it with a NE exposure, Southern or Western will probably result in warping or even melting the vinyl. Overheating the insulated glass units and breaking seals is also a real possibility.

Old school, but have you considered awnings for the southern exposure?

Thanks, everyone!
Some feedback:

1. The 'bracket' in the picture are the plugs for the weep holes in the vinyl windows.
2. Storm Windows: I agree. Not the right solution here.
3. White Shades: Yes, that is what are on the windows. This particular window is in our bedroom. In addition to the shades there are 'black out' curtains.
4. Trees: We love trees. There are some big maples a bit north and east of here. It is like night and day walking in and out of their shade. Even if my time machine was working I think there would be an issue. Since these windows face east they get the most sun from 8-12. During that time the angle of the sun is such that to get a tree to put shade on the window it would have to be very tall or very close to the house.
5. Soffit vents are clear. A/C is about five years old. High Performance. Working well.
6. Awning. Yep, that would help. Though it has some of the same issues as the trees. They would either have to come out very far or go very low.
I actually saw some Coolero shades at the store today. That could be an option.
7. Film. Yep, I think this is the way to go. I picked up some today and I'll try some experiments.

Again, thanks for all the help and advice. I really appreciate it.
