Installing Phifertex screen

I'm in the process of installing new Phifertex vinyl mesh screen on the windows of the boat. I've heard (somewhere, and do not remember where) that the edges should be folded over and sewed. But try as I might I cannot figure out why this should be necessary. I understand about cloth -- the edges will fray. But I cannot see this stuff fraying,.

So before I proceed (gotta wait for my snaps to come in from Defender anyway) thought I would just ask if I am making a big mistake by not folding the edges over before installation.

All I can tell you is mine are all folded and sewn. I couldn't imagine it any other way.

Yeah, my old ones (which I am replacing) are folded and sewn also. But why???

Greetings,
Mr. j. If the edges are folded over it makes a double thickness for the snaps to attach to does it not?

Probably doesn't need to be folded over...but probably does need reinforcing....there are many ways to strengthen an edge other than folded and sewn...try whatever you think works and meet's your eye approval.

Yes, indeed it does. But (a) I cannot see why that is important, and (b) if it were important, then a small cut-out piece to make a double thickness for the snap would work just as well.

We are not talking about a lot of pressure on these snaps. They just sit there, enjoying the view, and doing nothing more than that. One possible argument would be that when you pull them off, having a double thickness might be good. Not a bad argument, actually, except that they do not get pulled off very often, and when they do a small tool is available to pull them off which does not strain the surrounding area.

Hey, I am not trying to start an argument! If people want to fold and sew, that is just fine. I am just trying to figure out whether or not there is any good reason (other than personal preference) to do so.

Probably being a single guy is part of my problem here. I feel sure that a woman on board would know such things -- they probably teach it in Home Ec 101.

Greetings,
Mr. j. Well, I don't know the reason for hemming either but other than a rag of some sort, EVERYTHING has a hem or a turned over edge. You must have a much more accessible/memorable spot to store your small unsnapping tool than I do and the patience to go and find/get it. When it comes to removal, fingers and thumbs all the way.

Ours are doubled over and sewn. When snaps get stiff...you will be glad they are sewn...and when that straight line wind hits you you, you wont have to watch them sink ...blub...blub...blub....

a small piece of webbing folded over could be used to double the strength and the loop to make it easier to grab...I agree not everything HAS to have a hem on it as long as it won't unravel or fray. There are different kinds of edging, some sewn but some that can be glued or "ironed" (glued) on.....

Actually, two small flat-blade screwdrivers would work also, but yeah, I am pretty anal when it comes to where things are stored on the boat. All the "canvas" stuff is in a drawer. :-)

Mine are folded hem design. I was glad when reinstalling them after having them off for a few months, those suckers fit tighter than I thought. Must have shrunk a bit during storage?

And having hems helps when they shrink? (I do not much think that vinyl mesh shrinks, by the way!)

But wouldn't the pressure required to pop a snap be the same whether it is a single thickness or a double thickness???

Ding Ding Ding. RT wins. You need to have a good bit of fabric between the two parts of the snap to hold onto. It's much like a grommet. Otherwise it will be a weak link and rip a hole in the fabric with a simple tug to get them off. I fold mine over twice for a triple thickness. It also gives the mesh a good stiffness to it like a frame.

You don't "have" to do this, but this is why it is done. I also use double seams over that hem to keep the edge flat and neat. But that's just me.

And when your snaps get stiff or hard to press on, use a little vaseline or chapstick.

You can blow this picture up to see how mine are made. Temperature affects them. You can see that they can get tight. You need something that won't stretch out of shape when you pull on them.
