wood and wood products is the wood handbook fpl 1972 , which is now available in a revised version fpl 1989 . chapter 3 of the wood handbook on the physical properties of wood has a section on thermal properties that includes information on the thermal conductivity, specific heat, and thermal diffusivity of wood.
variety of products. this variety is a result of a spectrum of desirable physical characteristics or properties among the many species of wood. in many cases, more than one property of wood is important to the end product. for example, to select a wood species for a product, the value of appearance-type properties, such as texture, grain

the thermal conductivity of wood is relatively low because of the porosity of timber. thermal conductivity declines as the density of the wood decreases. in the direction of the grain, the thermal conductivity of wood is about twice what it is perpendicular to the grain. for example, the thermal conductivity of pine in the direction of the grain is 0.22 w/moc, and perpendicular to the grain 0

this look into wood movement deals only with solid wood. many materials that you will use are not actually solid wood, and do not display much expansion or contraction due to moisture. in some ways, this can be a boon to you as a woodworker, and you may design with these materials to overcome some wood-movement issues.
we have no relationship with advertisers, products, or services discussed at this website. thermal coefficient of expansion of building materials: here we provide a table of coefficient of thermal expansion of building materials - what is the linear expansion of glass, metal, wood, masonry or plastic in response to temperature changes.
r-values are additive. for instance if you have a material with an r-value of 12 attached to another material with an r-value of 3, then both materials combined have an r-value of 15. r-value units. as we said before, the r-value measures the thermal resistance of a material.
