A wood shrinkage and expansion calculator The Shrinkulator helps you estimate dimensional changes in wood either shrinkage or expansion based on changes in the woods moisture contentIt is applicable to wood whose moisture content is at or below the fiber saturation point (about ).

DESIGN ESSENTIALS FOR CONTROLLING MOVEMENT INDUCED the coefficients of thermal or hygrometric expansion of plasterboard are wood movement can be minimized

The general consensus is that designers of wood frame buildings do not need to account for thermal movement as thermal expansion is offset by the shrinkage of wood due to increased temperatures and moisture losswhich designers do need to consider.

Expected movement can be accurately predicted which means avoiding potential problems down the roadIn this article well explain the importance of understanding wood movement how to use a moisture meter to measure the moisture content (MC) of trim how to decide when a load of trim should be

THE EFFECTS OF BUILDING MOVEMENT furniture and vehiclesBuilding floors and roofs thermal expansion and contraction

Wood movement can ruin a seemingly well constructed projectLuckily getting ahead of the material and calculating wood shrinkage and expansion is fairly easy all you need to do is multiply three numbers togetherHeres how to find themStep Measure the boards widthKnow that

Wood is a very complex material with many variables that will affect moisture content and wood movementIt is not possible to predict accurately the movement of a single piece of woodThe average of a quantity is much more predictable.

For all practical purposes thermal expansion and contraction of wood is not an issueThat said warmer temperatures speed the exchange of moisture within the wood

The thermal expansion of wood in the direction of the grain is very littleIn the radial and tangential directions temperature movements are much greaterThe relationship between the thermal expansion coefficients and moisture contraction coefficients of wood in different directions relative to the grain is in the same class in terms of size.

This number can be obtained by consulting a Wood Movement Reference Guide or by using the simple table included in the original article (see below)For flatsawn red oak the value isFor flatsawn red oak the value is ..
