Re: ban treated wood

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Both ACZA & CCA are being phased out. Around here it looks like CBA will be the replacement (the proprietary name is "Wolmanizing"). Non toxic, non corrosive, ICBO approved, available in D.F.@ .2 above grade & .4 for direct burial. Looks like good stuff & I've changed my spec sheet accordingly.

Most likely CCA pressure treated wood will be out of use for residential
construction in a few years. Alternate chemicals have been registered, but I
am more in favor of a non toxic product from recycled materials. How about
the "PowerSill"? a high strength, composite material impervious to dry rot
and pests for use as shearwall sill plates? Also we need a non toxic product
for wood landscape/retaining walls. Maybe these products already exist, does
anyone know?
