I am remodeling a master bedroom that was a carport with a concrete pad poured over the original pad to level it with the home. This was done 15 years ago. It had a big termite problem. All drilled and treated and I am looking for termite proof drywall. I see old news about EcoRock but can't find any suppliers. Then there is DensArmour Plus but it specifically doesn't say its termite resistant. Covering metal studs. Any suggestions? Thanks.
