Cement siding thermal expansion.

The coefficient of linear thermal expansion clte of any material is the change of a material s dimension per unit change in temperature. Longitudinal cote 6 7x10e 6 in in f transverse cote 7 65x10e 6 in in f. Certainteed products are all designed to work together and give your home a beautiful finished look. From siding and shingles to styles and colors.

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. Thermal expansion of fiber cement siding. Explore our design tools to help you select the perfect combination of colors and styles for your home. James hardie recommends designing for this type of movement on buildings with long runs of continuous siding.

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. Generally linear thermal expansion is most applicable to solids. Weatherside fiber cement siding is the one and weatherside fiber cement siding is the one and only solution for replacing or repairing old asbestos siding shingles. 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.

Under normal conditions movement due solely to thermal properties is accommodated by the conventional 1 8 recommendation. Poplar therma siding v notch. 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. But conversely wood responds more dramatically to changes in moisture level.

Special thanks to reader eric p e. 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 thermal resistance of all of the components in the assembly. Expansion joints aren t necessary.

The linear expansion of a heated solid or liquid is measured by. It is available in a variety of sizes and shapes to match many of the old siding shingles installed over the last 60 years. The coefficient of thermal expansion or clte coefficient of linear thermal expansion. There s a lot to consider when creating your home s exterior.
