Pressure-treated lumber has been available for about 60 years. Most original formulas centered on arsenic as the main preservative, to help lumber withstand the extremes of outdoor use. While over time small amounts of chemicals from treatments such as CCA may have leached out of the treated timbers, a 2004 report in Wood and Fibre […]

More than once (especially in California), it has been suggested by lumber yards to use cedar or redwood posts for pole buildings, rather than pressure preservative treated wood of other species. The lumber yard sales people are of the belief the cedar or redwood posts should have adequate natural resistance to decay to last the […]

The smell of fresh sawdust on a crisp fall morning, the slap and ring of hammers on boards, the sturdy feel of new framing – what’s not to love? So it’s no surprise when builders set out to frame a pole building, sometimes they use a little more lumber than really needed. Sometimes a lot […]

In the United States, there are four prevailing species of timber which is used for framing lumber. Douglas Fir-Larch – which includes Douglas Fir and Western Larch (Tamarack). Prevalent along the West Coast, it is also known as Oregon Pine or Red Fir. Hem-Fir – another western lumber species group which includes California Red Fir, […]

We recently had one of our engineers specify the use of glulam pressure treated columns to support one of our custom designed pole buildings. The client was concerned about pressure treated glulams in the ground, so it was time for some heavy duty research. According to the American Institute of Timber Construction (AITC), structural glued […]

I do a lot of research on most everything I blog about.  I want you to have the most solid and recent information, along with my advice as to how to put it to best use.  I found this recently at www.spib.org: “The Family owned and publicly traded companies that choose to use the SPIB […]

Brookfield Timberlands of Vancouver, B.C., Canada owns over 3800 square miles of forest land in Canada (larger than the land area of Rhode Island and Connecticut combined). They are one of North America’s largest log exporters. One of Brookfield’s partners feels a timber supply “shock” is fast approaching which will lead to significantly higher prices […]

As I said yesterday, between 1952 and 2001, more trees grew, more trees died, and more were harvested.  Why? Forest density has a huge role in tree morbidity.  Forest restoration begins with sound ecologic management practices. I have a home in the state of Washington, and in fact, live a good share of the year […]

There have been times when I have seen manufacturers of all steel buildings attempt to portray pole buildings as being less than ecologically friendly. The premise being steel is 100% recyclable, while wood somehow is not. Or, by using wood in construction, we are somehow cutting down all of the trees! Today, forest growth in […]

Green building is one of the most dynamic market forces in construction today. Pole buildings are considered sustainable, but until very recently little documentation existed on the energy efficiency and the reduced impact on the environment created by pole barns. “Green building” is based on producing more sustainable buildings and is the basis for green […]

Let’s start in the forest… When David Friss of Anchorage worked for NOM ‘s Environmental Research Labs in Boulder, he was once asked why lightning sometimes spirals down the trunk of a tree. While the answer was not proven, we observed the path of least resistance might follow the spiral grain of the wood. He […]

Need a piece of lumber? In most of the United States, you get one from your local lumber yard or “big box” store and do not have a choice as to whether the lumber is “green” (moisture content of over 19%) or dry. For the most part, what is available at the retail level is […]

Grab any piece of lumber, with a narrow edge pointed up. Look down the narrow edge and you will normally see an upward or downward arch, or bow to the wood. An upward arch is “crowned up”.  This is a common lumber defect.  When building your new pole building, it is important for the crowns […]
