Wood Fiber Insulation R Value. Natural carbon negative building material. In hardwood it is 071. We have seen some estimates of an R value of 34 per inch for versions of insulation that contain a mixture of wood fibers and chopped paper. Therefore wood-fibre panels need to be a little thicker to reach the same R-values as polymer foams.
This means that a log home that does not use any other insulation materials would be significantly inefficient at conserving energy. Recommended install density is 2 -3 lbscf. As a benchmark one inch of solid wood has an R-value of 1. GO Lab a privately-held building products company was founded in 2017 with one purposeto manufacture high-performance wood fiber insulation for the first time in North America. Pavatex wood fibre insulation boards are installed directly onto the outside of external walls irrespective of whether the walls are constructed from solid or cavity masonry or timber frame. The panels offer R-values in the 35 to 39-per-inch-range while polymer foams have R-values in the 45 to 6-per-inch-range.
