"Definition of CLTE: The coefficient of linear thermal expansion (CLTE) of any material is the change in the materials length [and to a much lesser degree the width or thickness] per unit change in temperature.CLTE applies to the length, width, and thickness equally, not "too a much lesser degree". The SI unit of thermal Thermal expansion coefficient, abbreviated as \(\alpha\) (Greek symbol alpha), also called coefficient of thermal expansion, and linear thermal expansion coefficient, is the percentage change in the length of the material per degree of temperature change, heated solid or liquid. Optical imaging can also be used at extreme temperatures. The thermal expansion of marble is about the same as granite - The CTE data is calculated by the change in length divided by the quantity of the length at room temperature, multiplied by the change of temperature. The exact definition varies, depending on whether it is specified at a precise temperature (true coefficient of thermal expansion or a-bar or over a temperature range (mean coefficient of thermal expansion or a).The true coefficient is related to the slope of the . That might be just three or four 2x4 or 2x6 widths (depending on how the house is framed) - So take a look at the framing plan for your house, add up the pertinent widths along the long dimension, and then plug those into the table above, probably assuming the wood is pine. Linear Expansion:- When the expansion due to heating occurs only along one direction, the expansion is said to be one dimensional or linear expansion. Steel has been proven to be compatible with GreenGirt and has a lower coefficient of thermal expansion than the surrounding framing/sub-framing, making the 3/32" gap more than enough to accommodate the thermal expansion. Rigakus industry leading differential TMA is the instrument of choice when measuring low-expansion materials, and when accuracy is important.
