With Rosboro Treated Glulam

As the leading producer of glulam products in the U.S.. Rosboro has once again responded to customer demand and is norv offering a 24F l.8E Treated Glulam.

A Product You Know and Understand

Rosboro Treated Glulam is a 24F glulam beam made from Southern Pine and treated to resist rot and decay. Installation is easy because the beam is straight. has no top or bottom. and is manufactured to match standard framing widths.

Treated with Permapost K-8

K-8 is an industrial wood preservative and water-repellent trealment containing solubized copper-8-quinolinolate. providing chemical resistance to insects. decay, mold, milderv and bacterial growths. lt is a clean, non-srvelling. non-leaching. and non-conosive treatment.

Easy and Safe to Work With but rvith simple precautions is easy to work with. K-8 is lorv in toxicitl to humans and is the onll wood preservative approved by the FDA as registered by the EPA for treatment of rvood products that come in contact rvith foodstuffs.

Treated Glulam not only resists rot and decay.

Recommended Applications

Treated Glulam is recommended for uses such as decks. porches. trellises and balconies rvhere the member mav be directly exposed to the elements but won't reach the equilibrium moisture content level of l6% (the threshold for rvet-use).

When You Need lt To Last shortages and as a non-polluting substitute for lead in gasoline) and has continued ever since.

The difference now is that ethanol has the potential to take on a much larger role in our society. North America needs a domestic. clean and abundant alternative to fossil fuels-both to end our dependence on Middle Eastern oil. which is causing all kinds of problems. and to reduce emissions of carbon dioxide and other greenhouse gases.

The biggest challenge is cost. Most ethanol is made from fermented starch from corn or sugar from sugarcane. But the process is so expensive that the U.S. industry (rvhich accounts for 97% of North American production) has to rely on government subsidies. rvhich are set to expire in 2008.

In his State of the Union address. President Bush made the development of clean. alternate fuels a priority. Horvever. instead of continuing to subsidize an uncompetitive industry. the government is investing millions of dollars developing ways to produce a new type of "cellulosic" ethanol. rvhich is made from the cellulose in agricultural and forestry rvaste.

In addition to being substantially cheaper to make. cellulosic ethanol may reduce CO2 emissions by more than 907c over gasoline. compared to just l8-297c for conventional ethanol. It also lorvers emissions of carbon monoxide and other pollutants. and certain production methods generate electricity. rvhich is used to produce more ethanol and further reduce costs.

While the technological hurdles are being overcome. auto makers are doing their part to promote increased use of cleaner fuels by producing flexfuel engines. rvhich can use blends of up to 85% ethanol (to gasoline) compared to typical blends ofjust 107r.

So far. the market has been slorv to respond. Ethanol use has risen substantially since 2000. but even though more than four million vehicles on the road today have flex-fuel engines. most still run on gas. But the need is great and the solution makes sense. so there's every reason to believe that clean. domestically produced ethanol rvill allorv a significant reduction in gasoline consumption at some point in the not-too-distant future.
