  • That will not burn, at worst it might melt a little.

  • Distance matters. The real hot spot is inside of the dryer right beside/behind your clothes. The vent coming out of the dryer, is almost a foot away, and there might be too hot to touch with skin. A foot from that spot it will be quite warm to skin. As long as everything is working well. A lint or other fire changes things.

No. A fire in a dryer vent is more likely to be due to lint build up.

Your fiberglas does not burn easy, it could melt but at very high temperatures.

Much higher then the dryer went could ever produce.

fiber glas

It is advisable to clean the vent once in while to remove the lint and improve the air flow
