I have a cool wood screen door which my wife wants to turn into a storm door. I think its suitability is marginal. As in, it would probably work but I'd prefer a little more structure. I'll consider bolting a custom steel frame to the inside of the door but it occurred to me today that lighter weight glass might be the ticket. Does such a product exist?

Well, there's rigid plastic, which is much lighter weight than glass for similar strength, but generally more subject to scratches. There are also plastic film products that would be similar to a screen in terms of weight and installation, some of which are very clear.

Glass weight is primarily a function of thickness, so thinner glass would be lighter than thicker glass, but without knowing what thickness glass you are contemplating now, it's unclear if you could go lighter or not.

Glass for a storm door should be tempered, which means 3mm / 1/8" is as thin as you can go (thinner glass is made, but it cannot be tempered and would present a cut hazard - since the tempering process also strengthens the glass, the thinner untempered glass would also be much weaker, and thus more prone to getting broken and causing cuts.)

  • I assume I would use 1/8" glass. The porch has 13 windows and none are tempered (old house) but I imagine tempering is a good idea on a door. I was hoping to learn about a glass product will the clarity of glass but with the weight of plastic. In the end, it might be more affordable to reinforce the door rather than solving the problem through special glass.

    Glass-clear plastic is easy. Keeping it glass-clear is the problem.
