Calculate The Amount Of Hardie Plank Siding

Hardie Plank siding is available in many colors, sizes and textures.


Hardie Plank siding is a fiber cement-based siding product produced by the James Hardie Corp. When purchasing Hardie Plank siding, it's important to choose the correct amount for your project, plus a bit of extra material to account for installation errors and future repairs. At the same time, you don't want to waste money and buy more than you need. Fortunately, it's fairly easy to calculate how much Hardie Plank siding you need, based on the design and size of your home. Does this Spark an idea?


Instructions


1. Sketch each of the exterior walls of your home on a sheet of paper. Scale is not important, but capture the basic shape. Divide each sketch into sections based on their shape to make them easier to measure. For example, a rectangular wall with a sloped roof easily becomes a rectangle and a triangle.


2. Measure your home using the shapes on your sketches as guides. For the rectangle and triangle example in Step 1, you would measure the length of all three sides of the triangle, then transfer these dimensions to your sketches. You would then measure the height and width of the rectangle and transfer these dimensions as well. When you are done, you should have a sketch of each of your exterior walls, including dimensions for each component.


3. Calculate the area of each section. To calculate the area of a rectangle or square, multiply the length times the width. To calculate the area of a triangle, multiply the height of the triangle by the length of the longest side, then divide by two. Once you've calculated the area for each section, add all of the areas together to determine the total square footage of your home's exterior.


4. Measure all doors, windows and other exterior areas that will not require siding. Determine the total area for all of these items, then subtract this figure from your final square footage. This figure represents the total square footage of Hardie Plank siding that you will need to purchase.


5. Add about 10 percent to this total square footage before ordering your siding. It is often difficult to match the color and texture of siding in the future, so buy extra. Some material will be lost to cutting during installation, and installation mistakes are possible. Having a few extra planks in storage will be useful for repairs in the event that your siding gets damaged.


6. Determine how much trim you'll need. HardiePlank is usually installed in conjunction with corner beads, window/door trim and soffit trim. Measure the total linear feet for each of these types of trim and indicate these quantities on your order forms.
