Is there any drawback to leaving 6-inch-wide white pine covering a catheral ceiling unfinished?
For aesthetic reasons I am using 6″ wide 3/4 ” thick, white pine boards to cover my catherdral ceiling. The unvented cathedral ceiling has 4 ” of closed closed cell foam, followed by 6″ of open cell foam 0.8lbs/cuft, followed by 1 1/2′ XPS over the rafter cavity for reduction of thermal bridging. The 5/8″ plywood roof deck is covered with #30 felt paper and Certain Teed Energy Star certified asphalt shingles of high reflectance.
My question is: are there any drawbacks to leaving the white pine boards unfinished? I want the pine boards to be left as natural as possible, but all finishes which I have seen eventually darken or yellow the wood. I DO NOT WANT THIS TO HAPPEN IN MY HOUSE!!!
If there are any significant reasons why I should finish these beautiful natural pine boards, the finish must be low VOC and keep from darkening or yellowing the natural wood. This new home will be Energy Star certified and also air PLUS certified and must have low VOC finishes if I choose to use them. Thank You!!
