Plexiglass window thickness?

I'm in the process of replacing the leaky old tempered glass windows in our Albin Vega with dark smoked Plexiglas. The plan is to use the two-side tape and Dow795 method, no fasteners. The windows have no curvature, and the openings are about 7" tall by 48" long.

Does anyone have any industry inside information, strength data, or hard-earned personal experience to help me determine the appropriate thickness to use?

Re: Plexiglass window thickness?

I suspect the trim is leaking not the glass. Tempered glass can be restored with auto glass restoration products.

Choices for trim restoration depend on how bad the gasket material is but there is also a wide range of rubber/vinyl restoration products available at most auto parts stores.

Try repair/restore before replace.

Re: Plexiglass window thickness?

If you do go with plexi, go with the same thickness as the OEM glass.

If you are changing mainly to get the tint, you can get tinting film and apply it to the automotive glass cheaply and easily.

The automotive grade glass is better than plexi in just about every way possible.

Re: Plexiglass window thickness?

As you are not using the original frames you are not restricted to thickness. As there is no curvature also that doesn't restrict thickness. I would suggest 1/4" to 5/16" possibly, maybe 3/8".

I agree with the method and will be doing the same myself.

Thanks, Brian. In that case, you should take a nice Christmas vacation to Florida and help me install these things. That way, you'll be all practiced up and ready to tackle yours in the spring!

No need to thank me.

Re: Plexiglass window thickness?

If the original material was tempered glass, why not replace in kind? You can order a replacement from your local glass/mirror shop. You'll need a template--the old glass,if intact will do.

BTW, my replacement port lights were 1/2" plexiglass.

Re: Plexiglass window thickness?

Why not 3/8" cast acrylic?

My hatch is 1/2-inch plexiglass. You can stand on it without fear of breakage.
