Alternative glazing idea: silicone and glass fiber

I was thinking of how to have fire in a greenhouse.
Stoves of any kind would need a thimble of fireproof/resistant material for their  exhaust.
I want to use removable flexible glazing which usually means flamable plastic sheets.
But the Instuctibles member Thinkenstein,has a technique that might make for good a fire proof glazing that can also be rolled up during the hot months:

In the comments the creator say it is flammable,but I don't see why it would be.
I would do this over aluminum or fiberglass window screen

I'm thinking a fair bit about greenhouses and heating options myself these days.  I think it makes more sense to go with known systems than to speculate.  I think if the creator of something says it is flammable, I wouldn't second guess them about it.
But, I'm looking at getting a functional greenhouse with a minimum of effort and not all that interested in experimenting.

Good point. I love experimenting,so I if I really want to know I will just make some and test it.

I had a greenhouse with two woodstoves in it years ago, with ordinary fiberglass panels for the glazing, and plywood on the north side.  The stovepipes went through metal panels which replaced sections of the plywood, which placed the stoves on the north half of the greenhouse.  We used fans in the stovepipes and elsewhere to move the warm air around.  It worked pretty well...we were growing basil to market through winter (it needs temps above 50F to grow), but someone had to camp out in the greenhouse on the coldest nights to keep the fires fed!

One idea I have always liked was the Victorian heated wall . Basically you have a fire and the chimney is horizontalish  in a brick wall . The wall acts as a mass and heats the green house plus acts as a heat storage for the greenhouse the rest of the year no issues about the fire
