Cement siding thermal expansion.

Certainteed products are all designed to work together and give your home a beautiful finished look. 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 following expansion values should be used for considering this type of movement. 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.

Thermal expansion of fiber cement siding. Under normal conditions movement due solely to thermal properties is accommodated by the conventional 1 8 recommendation. But conversely wood responds more dramatically to changes in moisture level. Generally linear thermal expansion is most applicable to solids.

Expansion joints aren t necessary. 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. The coefficient of thermal expansion varies between 3 6 10 to 7 6 10 in in degree f according to most panel manufacturers. The linear expansion of a heated solid or liquid is measured by.

The thermal resistance of all of the components in the assembly. From siding and shingles to styles and colors. Special thanks to reader eric p e. James hardie recommends designing for this type of movement on buildings with long runs of continuous siding.

Poplar therma siding v notch. 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. Coefficient of thermal expansion cote per astm e228 is. Longitudinal cote 6 7x10e 6 in in f transverse cote 7 65x10e 6 in in f.

The coefficient of linear thermal expansion clte of any material is the change of a material s dimension per unit change in temperature. There s a lot to consider when creating your home s exterior. Of these moisture is generally more significant. It is available in a variety of sizes and shapes to match many of the old siding shingles installed over the last 60 years.
