Using treated lumber greatly extends the life of the structure built, reducing the replacement cycle for that structure and the amount of material required to rebuild a non-treated structure. During the past 20-30 years, the pressure treating industry has helped save forest area equal to the size of New England by increasing the effective life of outdoor structures.

Generally no, you will obtain nowhere near the same level of durability. Lumber must be pressure-treated to obtain the proper penetration depth and chemical level for adequate long-term protection of the lumber. Field treatment with organic solvent-based preservatives works acceptably well on lumber ends but not on the flat surfaces. This is because end-grain of lumber absorbs preservative up to 100 times more than the flat surface.

Recent studies have shown that you can use a Delmhorst meter with confidence at the treating plant, job site, or when the wood is in service if the preservative is a "C oxide" formulation (CCA-C) widely used today. Our experience has shown that at higher moisture content levels (above 20 percent), chemically treated lumber tends to yield somewhat erratic readings.

One quite important one: Use hot-dip galvanized meeting ASTM-A153/A653, 304 or 316 stainless steel or other fasteners, otherwise, your treated wood will last longer than the unprotected fasteners you've used to put it together. Do not use preserved wood in direct contact with aluminum. A poly barrier is recommended for any applications where treated lumber will meet aluminum flashing. No.

APHIS does not have information pertaining to lumber mills providing HT marked wood. Heat treated lumber with the required HT stamp must first be requested of the mill. It is the HT stamp that the inspection agency facilities will first be looking for when applying the grading agency official mark to the assembled product.

Reuters reported that big icebergs were coming off the Antarctic continent. The reports said that there were several factors contributing to this, among them, global warming. They ALWAYS say global warming, but never indicate what other factors may be involved. The Reuters report of the new iceberg was incorrectly linked to global warming. This is actually a naturally occurring event that is overdue to take place.

Yes. As with all construction wood, both treated wood and plywood should be dried to a moisture content of 19% or less prior to installation in a building to ensure dimensional stability. Drying is less important when CCA-treated wood is to be used outdoors.

If you purchase pressure treated lumber which carries the TP (Timber Products) stamp on the lable then you can be assured that the lumber has been treated to pass the minimum standards of two different teating processes. One test provides for the assurance that the lumber as passed a retention test. This means that all lumber with a .40 designation or the words ground contact on the end tag will have a minimum of 40 percent of chemical concentration in the wood.

Pressure Treated Lumber will weather over time to a silver gray color that might be appealing from an architectural perspective, but effective water repellants will retard the impact of moisture in the wood and, thereby, help reduce splitting, cracking and twisting that is common with these types of wood.

cases treated, 5 years longest survival rate. For more information about pancreatic neuroendocrine tumors and adenocarcinoma we suggest that you visit the Pancreatic.org web site The familial occurrence of carcinoid is a recognized but exceedingly rare event. This occurrence in two first cousins is suggestive. A blood test of DNA for the chromosomal abnormality thought to be present in the genetic aberration in such cases is under study and development at present.

Nyle offers the drying units only, and not the chamber structure. We do provide technical plans and specifications for the construction and/or supply of the drying chamber with each purchase of a Nyle unit.

A lot. In Fact, some species of wood are more than 50 percent water in terms of their weight when freshly cut. Once wood is dry will it remain dry? Wood is always trying to come into equilibrium with the air surrounding it, so its moisture content can change somewhat after it's been dried.

Test results have estimated that recycled plastic will last over 400 years with only minimal degradation. Compare that to a deck made of wood!

Reclaimed lumber is simply wood that has been discarded or donated because it is no longer needed for its original purpose. The majority of lumber we use for our frames comes from deconstructed homes in the Pacific Northwest.

Because of the high copper content of CA, extra care needs to be taken in the selection of fasteners. All hangers and fasteners must be hot dipped galvanized to the G185 standard. A common brand name that meets this standard is Zmax, manufactured by Simpson Strong-Tie. Stainless fasteners are recommended for best results in marine climates. Never mix stainless fasteners and galvanized hangers or vice-versa.

The only ways to lower the salt concentration in saline and/or sodic water are through dilution with non-saline water, reverse osmosis, or salt precipitation with an evaporation process that leaves salt behind and traps evaporated water. Reverse osmosis is expensive, and evaporation and salt precipitation treatment is neither economical nor feasible with large quantities of saline CBM water.

Environmental Justice is the fair treatment and meaningful involvement of all people regardless of race, color, national origin, culture, education, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.

ACQ lumber is safe when handled properly and presumed to be non-carcinogenic. However, acq treated lumber has a corrosive effect on most metals.
