SIP fire, mold and insect treatments
I have reviewed approximated a dozen sites using SIPs in Southern California. One had what appeared to be Copper Napthanate on the strandboards however the sills appeared to be standard timber (not ‘pressure treated’) lumber.. I was also told that a few rep’s are promoting a fire retardant treatment. I really do not want to experiment with products that have not been thoroughly tested for compatibility or a long period of time.
Any feedback on these issues?
