Hello again. I’m trying to understand wood rot. Obviously its caused by moisture but it seems from what I’ve read that rot is an organism feeding on the wood and as such needs warmth as well. Does this mean that wet wood kept at say 25 or 30 degrees won’t rot or won’t rot as quickly as damp wood at 60 or 70 degrees? I’ve got scraps of wood from my renovation in my yard that have been out in the weather for about 8 months. They don’t seem to be rotting. The solid scraps and plywood scraps are discolored but seem solid which surprises me. How long does it take for rot to start? As i’m siding I’ve got most of the plywood covered with tar paper and whats not covered with tar paper is covered with the yellow densglass gold sheathing. After one nasty storm where some areas of plywood under the densglass gold got wet i started worrying about its condition if parts were getting wet when it rained. I cut a small section of the densglass out to look at the plywood and it seemed fine. Solid when hit with the claw of my hammer. Plus whenever I cut the openings out to put the windows in the plywood always looks fine. So how long does it take for rot to start? Does the fact that no work has been done inside the addition yet help prevent rot since it might be easier for the wood to dry plus ,again, no heat and average temp between 30 and 40 degrees here. Believe me I’m glad I’ve had no problems but I also want to understand this so I can prevent problems in the future. Thanks again.
Edit. Oh yeah, i forgot, I saw on This Old House where they got beams for a timber frame from logs fished out from the bottom of rivers. This really confused me because this wood has been soaking on water for years and is fine. What am i not understanding?
