Sweetguth,

Keep in mind the insulation used on front doors, side and rear does not have to have the same thermal property as the insulation surronding the fire chute area.

I.E. the heat transfer from a chamber that is holding 250 degrees will be far less that the chamber housing a 1200-1800 degree fire chamber.

Might save a few dollars buy buying two different grades.

Hope it helps.
john

This link has some very good Knowledge about Thermal insulation.

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.

could the blanket insulation be used or is the board insulation worth the extra dough?

Try these folks

Action Gypsum Supply 9635 West Little York Houston, TX 77040 Phone: (713) 896-4002 Fax: (713) 896-4003 Email

I would look for this.

Thermafiber� Products

Thermafiber� Safing� Insulation is a mineral-wool-type insulation that resists temperatures up to 2,000�F (1,093�C) thus offering superior fire protection in a wide variety of fire-rated applications.
Thermafiber� Sound Attenuation Fire Blankets (SAFB) are the best way to stop sound in wall and floor-ceiling assemblies. Because this product is manufactured from slag, a by-product of iron ore reduction, and naturally occurring rock, the mineral fiber in these blankets are highly resistant to fire. Many of the systems this product is used in have high fire ratings as well as sound ratings.

Hope it helps,
John

i am slapping together a stumps clone and have come to the point where it needs to be insulated. Any suggestions for cost effective material? And ease of availability?

Thanks,
