pressure treats lumber
and timbers to above ground, ground contact and
in-ground structural use categories using the most
effective and environmentally conscious chemicals that
we can find – and trust. The result is wood that is
strong enough to stand up to wood’s natural enemies –
namely termites and decay.
WHERE IT CAN BE USED
Treated with a copper-based preservative and effective
fungicides, this wood is ideal for many applications
including decks, retaining walls, fences, picnic tables,
planter boxes, walkways, sill plate and structural
members. It comes with a limited lifetime warranty for
most residential applications.
Wolmanized® wood is a natural and environmentally
responsible choice: it's made from wood, a renewable
resource, treatment extends the life of the wood, and
the preservative used is as gentle as it can be and
still be effective and long-lasting.
Hot-dipped galvanized fasteners (meeting ASTM A 153) and
connectors (ASTM A 653 Class G185 sheet), or better, are
For Permanent Wood Foundations and corrosive
environments, such as areas with saltwater spray, use
304 or 316 stainless steel. Aluminum should not be used
in direct contact with this wood, unless an adequate
physical barrier separates the aluminum from the wood or
the manufacturer ensures the performance of the aluminum
For indoor applications, while galvanized fasteners are
preferable, the use of nongalvanized nails or screws of
sizes and types approved by the Model Code is acceptable
when attaching joists, studs or other framing to
Wolmanized® sill plate, provided the wood will remain
dry in service, protected from weather and water.
Likewise, the use of standard galvanized strapping,
anchor plates, or mild steel anchor bolts 1/2" diameter
and larger is acceptable for fastening Wolmanized® wood
to foundations, provided that the wood will remain dry
in service, protected from the weather and water.
This wood meets requirements of model building codes for
many applications, and code evaluation reports on this
wood have been issued by National Evaluation Service
(ESR-1721). The CA-C treatment is listed also in the
standards of the American Wood Protection Association (AWPA)
for above-ground and ground-contact applications (Use
Categories UC1, UC2, UC3A, UC3B, UC4A, and UC4B).
Internationally, it is approved by government and trade
agencies throughout Europe and in Australia, New
Zealand, and Japan.
