[T2] [Q] Heat Resistant Foam

[MUTS]

/Sorry, I meant to move from reflectrix to the fiber material of 
Ultra-touch barrier, which has a treated fiber-Â  It's class I rating 
means it is fire retarded (see below) but usuall Class I can refer to 
inorganic material like brick or glass.  Wood products are Class III. . 
Oddly, I looked at Reflectix  package, it has a Class ClassA/Class ! 
fire rating, so it will melt but not support combustion?

Cellulose Insulation has a Class 1 (A) Fire rating. It is treated with 
fire retardants to meet all federal, state, and local fire safety 
requirements. The rating applies to the building assembly. Cellulose 
insulation flame spread and smoke development ratings Walls with 
cellulose insulation are one-hour (or greater) fire walls and can help 
control the spread of fire.

Cellulose insulation, as a Class 1 or Class A material, means it has a 
flame spread <http://en.wikipedia.org/wiki/Flame_spread> of 25 or less. 
It also has a very lowsmoke development index level.

When properly installed, cellulose insulation can help reduce the spread 
of flames in house and building fires. Some cellulose insulation 
manufacturers have even qualified two and three hour firewall designs 
using Cellulose Insulation.
