1. What is Shiplap Siding?

Shiplap is a type of wooden board used commonly in exterior and interior construction. It features rabbeted edges that allow the boards to overlap, creating a tight seal while allowing for natural expansion and contraction.

2. How Does the Calculator Work?

The calculator uses the shiplap formula:

Where:

• \( \text{length} \) — Length of the area to be covered (feet)
• \( \text{height} \) — Height of the area to be covered (feet)
• \( \text{exposure} \) — Exposed face of each board (feet)

Explanation: The formula calculates the total linear feet of shiplap needed by accounting for how much each board overlaps with adjacent boards.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you purchase the right amount of material, minimizing waste and additional trips to the supplier. It also helps in budgeting and project planning.

4. Using the Calculator

Tips: Measure the length and height of your project area in feet. Determine the exposure (typically 0.5-0.75 feet for standard shiplap). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical exposure for shiplap?
A: Standard exposure is usually between 0.5 to 0.75 feet, but this depends on the specific product and desired appearance.

Q2: Should I add extra for waste?
A: Yes, it's recommended to add 10-15% to your total for cutting waste and mistakes, especially for complex projects.

Q3: Can I use this for both horizontal and vertical applications?
A: Yes, the calculation works the same way regardless of orientation. Just be sure to measure the appropriate dimensions.

Q4: How do I account for windows and doors?
A: Subtract the area of windows and doors from your total height calculation before using the calculator.

Q5: What's the difference between shiplap and tongue-and-groove?
A: While similar, shiplap has a rabbeted edge that creates a small gap between boards, while tongue-and-groove fits together more tightly.
