What are those baffles in my woodstove that look like they are styrofoam, but are made of something else. And where can I get more? I poked a hole in one of them and both are pretty scraped up.
They are made of several different materials depending upon the manufacturer. Usually the easiest and best way to get replacements is from the manufacturer. But if you can find out what the material is you may be able to find it cheaper elsewhere and cut it to fit.
Yeah if I can get cut to cut myself and fit them myself, that would be great. The original ones (there are 2) don't quite fill the space and there is about a half inch gap
Is there supposed to be an insulation blanket ontop to cover that gap? If not it isn't very effective. What stove is this?
Search "ceramic fiber board" or "ceramic insulation board"...then you just need to find the right dimensions for your application...its not the cheapest stuff in the world, but going aftermarket you can often get enough to make 2 sets of baffles for the cost of 1 from OEM...YMMV...

I used a commercial industrial ceramic fiber board insulation distributor near Pittsburgh when I was building rocket stove heaters. I just walked in one day, told them what I was doing and what I needed, and they set me up as a corporate account. I was buying cases at a time, and it was a helluva lot cheaper that way. (I did the same thing with the insulating fire brick manufacturer near Butler, by the way. Just walked in and started talking to them, and explained what I was building.) I don’t think they were selling direct to the public otherwise, and unfortunately I don’t have any links at this point.
that price on the ceramic board is about double on that E bay add. Unless includes freight. A 2ft x 3ft x 1/2" piece of KO type H board (2300 deg) should run apx $65. I just bought a piece last week from a company that works on kilns and heat treatment units. No freight as it is local to me. Shipping this stuff is a bit tricky as it needs to be sandwiched between a couple of wooden boards, it will not stand up to the gorillas of shipping concerns by itself. Cutting it to size is quite easy razor knife or I use a back saw very slowly. The particulate is not good for you. look up heat treat oven and/or klin repair/ construction companies in your locality. Amazon has listings also -pricy.
No, the is only empty space. It would be where the exhaust gasses pass from the front of the stove pass back to the chimney......if that makes sense.
Yes I assumed that. But some companies use an insulation blanket ontop of that baffle. Which is why I asked what stove it was
I have lots of gaps around the baffle boards in my NC30. It is intentional since things need to be able to move. The gaps actually shrink as it gets hot. They don't need to be airtight and you don't want them to crush when the stove changes shape. The boards are fragile and really expensive. I wish more noncat companies could figure out a way to do this with something sturdier like firebricks (Lopi) or stainless steel like PE does. Other than that fragile board, the noncats are pretty dang durable.
Glad you mentioned this HB, I meant to but was called to another thread and did not make it back. When I went to an EPA stove I understood the gaps around the edges were required.
