Hi All ;
Thought I would share a little old wisdom about natural fire protection.
It goes against the general idea of this forum, but it is worth considering… No finish on natural wood (Cedar in particular) none at all !
In the 1700's there were still large forests on the east coast and wildfire was a big concern.
Homes often used cedar shakes as shingles. Cedar boards as siding. Or cedar logs. Bug resistant , rot resistant, unfortunately also highly flammable.
Lets jump to current times. Cedar boards/shingles are still used as siding and occasionally as roofing.
More common as roofing is 3 tab asphalt shingles (also highly flammable) or metal roofing (not flammable itself but thin and heats up fast)
When wood is used now, it is sealed with some kind of product. This keeps the wood very nice looking. Of course it must be reapplied periodically.
Unfortunately that sealer keeps any water from soaking in.
Lets jump back to the early days. Many homes were saved with water... each home would be doused and with natural wood their homes soaked up that water , becoming very spark/fire resistant. Allowing time to soak neigboring buildings.
With a modern sealed wood house. Only with a constant stream of water being applied does your wood home stand a chance of surviving a wildfire. Turn your hose on a different building and the first one will catch...
The down side of course is your wood will grey. Many might find that not acceptable. I think it is...
I also think brick houses with slate roofs were a good idea as well... :)
