Looks like there was a bit of dust on the lens when I took this photo. It actually captures the varying colors of the beetle kill pine quite nicely. The usual yellow and orange pine is dissected by a blue and gray stain.
It seems unfair, the pine beetle gets all the credit for killing trees, when, technically it’s a fungi carried by the beetle that slowly strangle the core of tree. The beetles prefer living trees, boring tunnels in their skin. In fact, I’m sure the beetles don’t even know that they are the cause of the massive kill-off of trees here in the nearby Rocky Mountains.
While the additional waterproofing layers and furring strips added time to the labor on this project, the rough sawn 4/4×6″ beetle kill pine will hold up much better as a siding material used in a rainscreen application. After generously applying two coats of a stain/sealer on all surfaces of the siding, they were spaced, leveled, and attached using 3 inch deck screws.
In theory, air circulating over all four sides of the “screen” will allow the wood to age more gracefully than conventional lapped wood siding.
