Insulating Timberline850, a Covid Project.

[Greg G]

Can you confirm that this would work? It looks the same, but way less expensive. And I'm guessing I would need 3 of them (5 ft x 24 in x 1/2) for a 1300. Two might be cutting it close or short.

I paid the extra for the lynn material because it doesn't carry a health warning. Not sure about the material you linked.

 

[RemE]

Hmmm, my Lynn material certainly had big handling warnings. I would use a mask and gloves when working with any insulation material.

I would say that any 1/2 inch ceramic wool would be fine. The key point is to not have any exposed wool when done.

For the T1300 I used 6 x of the 24x25” Lynn packs that RemE used, so about 12 feet.. I would think 2 of the 5’ pieces plus a 2 ft from Amazon and the 1”rope (also 12 ft) for the rope I used it for the sides and then most of the rest behind the grease channel....
Last night I was cooking pizza and the grill was running about 470 for 2 hrs, the lid was 126 on the left... ‘this is a good addition especially if you have children....

Thank you both for the input on insulation. I was studying the pictures close and noticed a pipe protruding from the left side. In one photo it seemed "uncovered" and in another it looked like it had a galvanized pipe and matching cap over it. I do not see it in your "before" photo and I do not see it in mine either. Maybe I missed it, but I don't see any comments addressing that mod.

I added a cold smoke generator, sweet little add-on;

Add a "Smokin-It" Cold Smoke Generator to Timberline 850

I thought I'd consolidate all my information on this mod to my Timberline 850. This can be adapted to most any model grill. Cold Smoke generators were new to me, a small external firepot that just makes smoke which is fed into a larger cold box. This is used to smoke cheese, fish, salt and...

Oh wow. So many possibilities. I think between the shelf, insulation, and drip channel, I have my work cut out for me. I will certainly save that thread for the future. Thanks for the link. So many wonderful options!

RemE:
I like your templates. Any chance you feel charitable and want to retake photos of them with tape measure in frame? Or written dimensions on each side? I could grab cardboard or file folders and make templates, but yours seems to be very functional (with FLIR proof) and if you were willing, I'd love to benefit from the time and care you already put into the research and development of this mod. I'll make sure to take photos of any mods I do and add to the community here. Please feel no pressure. I would say "I'm sure you have better things to do," but your COVID posts lead me to believe that may no longer be true!

Sorry to say that for those exhaust port strips I just made those sample templates to convey what I did for the post, to show how the exhaust would flow etc. To make them I had measured the port width and height and had the stainless strips cut about 1/4" shy to allow them to be inserted from inside the grill easier.

Since I used one stainless bolt to hold the strips in each port, I used quick templates to mark where to drill the hole in the strips.

If I were doing this again, I would remove the back sheet metal panel and work from there. The key is that you want insulation in the lower barrel to flow into those exhaust port, especially the corners and rear. We are keeping this high heat away from the corners and sending it up into that rear box.

 

[John S.]

Also consider that you need to ensure that you do not decrease the air flow through the corner vents. My original plan for the vents caused an overheat to 600 when set to 400, the design that RemE designed works much better.
‘I used 20 gauge vs RemE’s 26 gauge., his is easier to work with, however I feel that the 20 gauge has better thermal properties..

 

[RemE]

My philosophy was that the ceramic wool is the thermal isolator, the thin stainless is merely an easy to work covering for the wool, to protect and isolate it.

 

[SpeedQuest]

ReMe... Did you insulate the whole under belly of the barrel (under your new exhaust plates), or just between the exhaust plates? The pictures aren't quite clear on that.

NEVER MIND... I reread and figured it out... making progress!

Yes, initially I was after the ports but decided to do the whole belly, and ultimately the whole grill. The insulation runs in the belly and up into the exhaust ports, under the added stainless strips.

 

[John S.]

'I insulated all areas with in the barrel (belly, back,sides,lid, under the grease channel ) and under the stainless strips also in the exhaust area.
set a cook @ 450 for 1 hr, lid went up to 124, also lower pellet burn rate...

Does anyone know if this reduces the amount of smoke the food gets, since less pellets are being used?

Doesn't seem reduce the smoke on mine.
