Smoker Insulatin

[ts8181]

Is there some kind of fireproof insulation I can add to the inside of my home made smoker to keep the heat in better?
Thanks!

Hey ts8181, here is what I plan to use:

http://www.roxul.com/building+envelope/products/roxul+afb%C2%AE

You can buy it here:

http://www.atsacoustics.com/item--Roxul-AFB-Mineral-Wool-2-inch-Case-of-6--1006.html

Shipping is a bit high due to the bulk, but this is the most affordable high temp mineral wool insulation I have found so far.

I believe they make a foil backed version, bit this product is more appropriately sandwiched inside the walls of your smoker, or you could wrap it around the outside. Do not line the inside of the cook chamber with insulation, or you will be eating fibers.

Here is another source. They have a 1/4 inch product available if you need it. I am sure thicker is better, but you don't always have room for the thicker stuff.

Good Luck

+1 on the Roxul AFB. Check their site for a dealer near you. About $35 for a bale big enough for a couple of amokers.

I put a welding blanket over the top of my cheap horitzontal offset and noticed a great difference in holding the temperature, especially on cold/windy days.
It doesn't look all that "professional" though but hey who cares.

About Selecting Thermal Insulation
A material's resistance to temperature and its ability to block heat are important factors to consider when
choosing thermal insulation. R-value measures the material's capacity to slow heat flow; the higher the R-value,
the better the material insulates. The chart below shows R-value for 1" thick insulation. To calculate the
R-value of additional thicknesses, divide the material's thickness by its K-factor. K-factor measures the heat
flow rate from one side of the insulation to the other; the lower the K-factor, the better the material insulates.
Use the chart to find the insulation material that best suits your application.
If insulating below 0° F, use polyethylene, foam rubber, aerogel, or polyimide insulation.
