What is the R value of wood shavings?

1 inch of wood has an R value of about 4. Compared to other material such as concrete it would require 18 feet to equal an inch of wood. So in a 3 1/2 inch stud wall you would have about an R-14 using sawdust or planer shavings. No wood will burn without a source of ignition and a supply of oxygen.Click to see full answer. Keeping this in consideration, what is the R value of wood chips?Wood chips do insulate but only at about R-1.4 per inch. Fibreglass is 3.5 per inch and extruded foam insulation 5.0 per inch.Furthermore, are wood chips a good insulator? Wood chip insulation is generally considered safe, although it offers very little R-Value for you. Back in the day before cellulose and glass fibre insulation products were available, sawdust and wood shavings were commonly used to insulate homes. Most people won’t remove wood chip insulation purely because of cost. Herein, what is the R value of sawdust? Re: Sawdust insulatioin Solid wood has an insulating value of R1 per inch of thickness so we can maybe assume an R value of 1.5 ish for loose sawdust. this means that in a 4 inch thick wall (3 1/2 actual) you would have an R value of 5.25. Fiberglass insulation will give an R value of 12 in the same space.Why do wood shavings insulate better than solid wood?There is such a large difference because wood shavings have air pockets and solid wood may not have any: air is a better insulator therefore, the shavings will make a better insulator. a) Convection could not occur in solids because the particles would need to move away from each other and this cannot occur in solids.
