Exhaust heat damage to luggage?

Doing my first ride and camp trip this summer. Is exhaust heat damage an issue with dry bags, duffels, stuff sacks etc?

The bike is a Tiger 800 XC, stock can. I already melted a strand of an $8.00 cargo net.

So I'm thinking of rigging an insulated heat shield mounted to the pannier rack.
I'll have a dry duffel strapped to the pannier and a couple of dry bags strapped to the rear rack/pillion. I really don't want to melt anything.

Anybody had any issues with that?

I have solved this problem in the past by buying a thin sheet of Teflon and mounting it to the luggage where it is near the exhaust pipe.

I mounted it using small screws and nuts.

On my R1200GSA sidecar rig I felt that even though I had yet to have any heat damage to anything in my pannier, I wanted to eliminate the possibility so I did 3 things:

1) Extenders/tips on the muffler to make sure all of the hot gasses are expelled beyond the pannier.

2) Fiberglass heat shield wrapped around the muffler for insulation.

3) Reflective gold foil on the pannier.

An air gap is THE best insulator against radiant heat, so reducing the amount of radiant heat from the muffler prior to the air gap between the pannier was important and then reflect any remaining heat with the gold foil.

Good suggestions. Thanks.

My Trax boxes don't go over the exhaust so it's heat rising through that gap to my soft luggage (rubberized dry bags, stuff sacks and cordura type luggage to be specific) strapped above that I'm concerned with.

I'm thinking I might fab a heat shield of aluminum that bolts to the back side of the pannier racks and rolls over the exhaust can leaving an air gap on both sides, then glue/epoxy/attach some sort of insulated reflective material to the hot side.

I'll look into exhaust extensions if they're available for the stock Tiger exhaust.

1200GSA sidecar rig! Cool. What is the size of the rear tyre?
Thanks,
Mark

Reflective foil is a bit expensive but is easily found via Google.

Aluminum with the reflective film towards the heat source and an air gap on each side should work really well.

The tire on the tug and the tub is 165 80 R15. Basically a stock VW bug tire. The wheel is an aftermarket aluminum VW wheel with a billet adapter.

Here is a pic of our rig before I did the current mods. I had placed some aluminum HVAC tape on the pannier mount, but it melted. It was up to Big Sur and when we stopped for the day I was shocked at how hot everything was in the left pannier.

What about aluminum tape?
It's pretty cheap and self adhesive.

This is exactly what I had tried and the adhesive melted. The adhesive on the gold foil does not fail under the same temps.

Keep it simple. Wood stove people have been doing this stuff for ever. A piece of metal between heat and bags. Airspace on each side.

You can use simple aluminum construction flashing . Bendable with fingers. Can cut by scoring with razor knife. Create creased edges by bending over the straight edge of a table and forming with fingers. Sorta like this. _l------------l_ immagine the dotted line is to the top. Does that make sense?
Hell for sharp, wear gloves.

Bend a couple ells on the edge and wrap around muffler. Anchor with hose clamps.

Moving air carries the heat away.
