Frequently Asked Questions
How does fire retardant treatment (FRT) affect fire endurance?
Does fire retardant treatment (FRT) make wood non-combustible?
FRT wood does not meet the requirements for non-combustible materials. However, in recognition of its very low flamespread characteristic, building codes typically allow FRT wood to be used in certain non-structural applications in buildings otherwise required to be of non-combustible construction.
