HI-BOR WOOD TREATMENT !! IS THAT ALL THERE IS?
Many people have come to realize that HI-BOR treatment , while very effective where it was intended to be used, is very ineffective in some pretty important places. Pictured above is a sticker from a piece of HI-BOR treated lumber. Notice that it specifies " for interior use, above ground and continuosly protected from liquid water". That effectively eliminates HI-BOR being properly used for sun decks, stairs, rails, board walks, bridges, garden structures such as grow benches and beds , trellises, fences, etc. which spend their entire useful life exposed to the weather.
The problem with HI-Bor in those applications comes from the tendency of the borate chemical to migrate to water. The more the material is wet, the more the treatment leaves the lumber , eventually leaving it with no protection from termite attack or fungal rot. For framing lumber that is to be covered and protected from the weather it is an excellent treatment, but ,used in the wrong application it can be a problem within a couple of years.
AN ALTERNATIVE IS AVAILABLE LOCALLY AT ARGUS BUILDING SUPPLY!!
CA-C treated lumber is formulated to hold up in the conditions that are challenging for HI-Bor. The active ingredient is copper which has been used for decades to successfully protect wood from termites and rot. An additional ingredient is the Azoles that aid the copper as a fungicide. The wood has a slight green tint from the chemicals. It can be cut , sanded , and painted just like HI-Bor.
There have always been safety concerns about treating chemicals. Check out the studies that have been done. Most of them conclude that CA-C is an effective treatment and presents no more health risk than untreated wood.
We stock all our 1" lumber CA-C treated; we also have 2x4 and 2x6 in 12', 16' and 20' and 4x4 in 8' and 12'. we do have a few other sizes in stock and can regularlly order just about anything. (Subject to the normal shipping schedules we all love so much) .
CA_C treatment costs a bit more than HI-BOR but when you factor in the longer life span from superior performance the cost becomes a pretty cheap insurance plan.
Give us a call and we will answer any questions you might have.
Come down and look, we can show you the product.
