Problem 4.26

 

Pressure-Preservative Treated Wood

 

See NDS sections 4.3.13 and C4.3.13 for preservative discussion.  A reduction is not necessary unless wood is incised.  See Wood Handbook chapter 15 for further discussion.

 

Fire-Retardant Treated Wood

 

See NDS sections 2.3.4 and C2.3.4 for fire-retardant discussion.  Reduction values come from "company providing the treatment and redrying service."  See Wood Handbook chapter 18, especially the section entitled "Fire-Retardant-Treated Wood," for further discussion.
