Understanding Moisture Content and Wood Movement .

For all practical purposes, thermal expansion and contraction of wood is not an issue. That said, warmer temperatures speed the exchange of moisture within the wood. Moisture exchange will happen more rapidly at warmer temperatures, but there is no thermal movement of wood worth measuring.[ Get Price ]

CBD-56. Thermal and Moisture Deformations in Building .

For solid materials the increase in length per unit length for one degree rise in temperature is known as the linear coefficient of thermal expansion. Values for the linear coefficients of thermal expansion for most materials used in building have been determined by various laboratories and are available in handbooks.[ Get Price ]

How heat affects timber International Timber

How This Works In Wood. When timber is subjected to heat, it expands. This process is known as thermal expansion and can cause warping, swelling and potentially shrinkage. As a hardy natural substance, trees have evolved to be resistant to this and can typically take temperature changes within their stride.[ Get Price ]

Controlling Wood Movement – Part II and New Product .

This movement occurs, because like solid wood, MDF expands and contracts with changes in moisture content. Unlike solid wood which sees the greatest expansion and contraction parallel to the growth rings but changes very little in length , the composite nature of MDF causes it to expand and contract equally in both width and length .[ Get Price ]

Thermal expansion - Wikipedia

Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.[ Get Price ]

DESIGN CONSIDERATIONS - masonrybc.org

DESIGN CONSIDERATIONS It is the responsibility of the designer to provide the location and type of vertical and horizontal movement joints required in masonry walls. The requirements for movement joints should be based on the following considerations: 1. Thermal expansion and contraction of masonry. 2. Moisture shrinkage and expansion of masonry units.[ Get Price ]
