CALCULATIONS OF INSULATION
 
Q - What is "K" factor?
A - This is a measurement of the value of any one material 1" thick. The lower the "K," the better.
 
Q - What is "U" value?
A - This is the value of a structure, such as the dry wall ceiling plus insulation plus air films plus air spaces, if any. The lower the "U," the better.
 
Q - What is "C" factor?
This is a measurement of the value of any one material in the given thickness. The lower the "C," the better.
 
Q - What is "R" factor?
This is a measurement of the resistance of a given material in place. The higher the "R," the better.
 
Q - How do I convert the "K" factor to a "C" factor?
A - Divide the "K," (factor) .... any material 1" thick .... by the thickness.

EXAMPLE:   The "K" value is .27. The material to be used is 3" thick. The "C" factor is therefore .09.
 
Q - How do I convert the "C" factor to a "R" factor?
A - Divide the "C" factor into the number 1.00.

EXAMPLE:   The "C" value is .09. Divided into 1.00, the "R" is 11.11.
 
NOTE: You must then determine the insulation material that has a resistance factor of 11.11 or greater to meet a "C" factor of .09. This value increases by adding the resistance of the other factors involved, such as ceiling board, air film heat flow, up or down, and/or dead airspace.
