What’s the Deal with Wood Fiber Insulation?
I’ve seen a lot of mentions for wood fiber insulation, usually applied to the exterior of the building. Has anyone used this product? My concern would be fire in addition to water absorption (whenever I’ve read an article on window installation they say “all windows leak – eventually” so if water is going to get into the wall assembly around the windows then wouldn’t the wood fiber insulation get soaked and rot – eventually?).
And with Roxul Comfortboard available and recommended in a wild fire zone, why would you put wood fibers on the exterior of the sheathing under the siding? It seems like a product with a lot of handicaps.
