Cement siding thermal expansion. 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. 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. Special thanks to reader eric p e. 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.

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. Thermal expansion of fiber cement siding. From siding and shingles to styles and colors. Certainteed products are all designed to work together and give your home a beautiful finished look.

The coefficient of thermal expansion or clte coefficient of linear thermal expansion. It is available in a variety of sizes and shapes to match many of the old siding shingles installed over the last 60 years. Generally linear thermal expansion is most applicable to solids. Poplar therma siding v notch.

The coefficient of thermal expansion varies between 3 6 10 to 7 6 10 in in degree f according to most panel manufacturers. Longitudinal cote 6 7x10e 6 in in f transverse cote 7 65x10e 6 in in f. The following expansion values should be used for considering this type of movement. Coefficient of thermal expansion cote per astm e228 is.

The linear expansion of a heated solid or liquid is measured by. 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. There s a lot to consider when creating your home s exterior. Under normal conditions movement due solely to thermal properties is accommodated by the conventional 1 8 recommendation.

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. Expansion joints aren t necessary. Of these moisture is generally more significant.
