The Hardie Board Siding Calculator is an essential tool for anyone looking to install Hardie board siding on their property. It helps in estimating the number of siding boards required to cover the exterior walls of a building accurately. By inputting the dimensions of the walls and accounting for windows, doors, and other openings, the calculator provides a precise quantity of Hardie board needed, minimizing waste and ensuring cost-effectiveness.
Formula of Hardie Board Siding Calculator
Number of boards = (Total wall area - Opening area) / Coverage area per board
- Measuring your walls: Determine the area of each wall you want to cover by multiplying the wall’s width by its height (in square feet).
- Accounting for openings: Subtract the area of windows, doors, and other openings from the total wall area.
- Considering board dimensions: Divide the total wall area (excluding openings) by the coverage area of a single Hardie board (which you can find on the product specifications or manufacturer’s website).
Table for General Terms
To further assist users, below is a table containing general terms and their definitions that commonly appear when using the Hardie Board Siding Calculator. This table is designed to help you understand the terms without the need for further calculations:
| Term | Definition |
|---|---|
| Total Wall Area | The combined surface area of all walls to be covered with siding, measured in square feet. |
| Opening Area | The total area of all doors, windows, and other openings within the walls, measured in square feet. |
| Coverage Area per Board | The area covered by a single Hardie board, usually specified by the manufacturer, measured in square feet. |
Example of Hardie Board Siding Calculator
Imagine you have a wall that is 20 feet wide and 10 feet high, with a total area of 200 square feet. If there is a window in the wall measuring 5 feet by 4 feet (20 square feet), the opening area to subtract would be 20 square feet. Assuming each Hardie board covers 5 square feet, the calculation would be as follows:
Number of boards = (200 - 20) / 5 = 36 boards
Therefore, you would need 36 Hardie boards to cover the wall, excluding the window.
Most Common FAQs
The calculator is highly accurate when provided with precise measurements. However, it’s always recommend to purchase a little extra material to account for cutting errors or future repairs.
While the calculator is specifically design for Hardie board siding. The formula can be adapted for use with other siding materials by adjusting the coverage area per board according to the specific product.
For walls with complex shapes or numerous openings. It’s best to calculate each section separately and then sum up the total. This approach ensures accuracy by accounting for every detail of the wall’s geometry.
