Is cement board considered non combustible?

Yes, HardieBacker® 1/4″ Cement Board is deemed noncombustible when tested to ASTM E 136 and can be used in conjunction with other noncombustible materials around a fireplace. This does not mean that clearances to combustible building materials can be reduced by using HardieBacker 1/4″.

Is drywall combustible?

As a home inspector, the important thing to know is most typical wall and ceiling assemblies (including tile and stone finishes set on conventional wood-framed walls) are considered combustible. Drywall is also considered a combustible material because of the paper facing.

Cellulose insulation, as a Class 1 or Class A material, means it has a flame spread of 25 or less. It also has a very low smoke development index level.

What does class A fire mean?

    Is there an ABC fire extinguisher?

An extinguisher with an ABC rating is suitable for use with fires involving ordinary combustibles, flammable liquids and energized electrical equipment
