Cement Siding Thermal Expansion

Of these moisture is generally more significant.

Cement siding thermal expansion.

Doggett 2012 places the coefficient of thermal expansion cote for fiber cement products at 3 6 10 to 7 6 10 in in degree f giving a linear expansion of less than 0 08 over ten feet of material. The cte employs reciprocal temperature units k 1 f 1 c 1 etc representing the length change per degree per unit length e g in in f or mm mm c. Generally linear thermal expansion is most applicable to solids. But conversely wood responds more dramatically to changes in moisture level.

The linear expansion of a heated solid or liquid is measured by. Longitudinal cote 6 7x10e 6 in in f transverse cote 7 65x10e 6 in in f. The thermal resistance of all of the components in the assembly. Therma siding has a far superior grain structure than cedar isn t dull like cement or composite siding isn t knotty yellowish or unsightly like scots pine won t split during installation and is easier on tools as compared to brazilian hardwoods.

The coefficient of thermal expansion varies between 3 6 10 to 7 6 10 in in degree f according to most panel manufacturers. Under normal conditions movement due solely to thermal properties is accommodated by the conventional 1 8 recommendation. Thermal expansion of fiber cement siding. Adding rigid foam insulation to the exterior of the home is a simple method of increasing the overall thermal resistance of the wall assembly beyond that possible with cavity insulations and thereby increasing the overall efficiency of the home.

Expansion joints aren t necessary. Certainteed products are all designed to work together and give your home a beautiful finished look. There s a lot to consider when creating your home s exterior. Poplar therma siding v notch.

Special thanks to reader eric p e. From siding and shingles to styles and colors. Different rates of expansion contraction between wood and cement products the thermal expansion coefficient of cement products is approximately twice that of the wood structure underneath it. Explore our design tools to help you select the perfect combination of colors and styles for your home.

The coefficient of thermal expansion or clte coefficient of linear thermal expansion. Coefficient of thermal expansion cote per astm e228 is. The coefficient of linear thermal expansion clte of any material is the change of a material s dimension per unit change in temperature. It is available in a variety of sizes and shapes to match many of the old siding shingles installed over the last 60 years.
