The material is foam, like the type in a cheap mattress.
The one in the link is too thick (almost 2 inches total — which is far too much).
I’d like material which maches the following.
1 inch thick (or even 3/4 inch, but no lower)
Any color.
Cylinder shape.
Preferably NOT hollow inside the middle of it (but ok if it is)
You may find something that will meet your needs by going into Google: foam tubes

We started putting up OSB, not we are told foam board is a better insulator and the siding will install straighter. Also told OSB will splinter when nailed to (haven't had a problem) and has a tendency for the nails to eventually pop out of and the board warp. The siding instructions seem to prefer over wood installation. OSB would strenghten the house, would it not provide extra insulation also and the OSB is the perfect thickness to line right up with the door and window frames. What are the pros and cons of each?
We had wood siding. We are removing it. It was installed over old sheathing from the 50s, which we are leaving on the house.
they do sell foam broad that is the same thickness as the osb. foam does have a better r value. what i do is use osb around window and door openings for strength and foam on all other part of the house. make sure you get a good house wrap like tyvek. when you use foam you really have to pay attention to where you put the nails if you don't hit any studs or wood the nail will not hold. that why installers like to use wood its faster, and if you miss the stud the nail will still fasten to the osb. it all depends on what is important to you you can use osb and get a higher r value insulation or use foam and get what ever your city requires for r value on insulation. i hope this helps you.

i removed a direct-vent fireplace from our family room and have to remove the venting and fill the hole in the wall. What type of insulation should I use behind the drywall? Is it OK to just use expanding Foam Insulation for the hole? I currently have fibreglass batt insulation in the wall
you don't need to check with the city for just filling a hole in your wall.
you can use any type of insulation you like. i think it depends on the size of the hole, because if it is relatively small, then yes, you could use the expanding foam thing that comes in the can, but if the hole is larger, then you may just want to use any kind of fiberglass insulation that rolls out.
