1. What is Shiplap?

Shiplap is a type of wooden board used commonly in construction and interior design, characterized by its rabbeted edges that allow boards to fit together snugly, creating a tight seal.

2. How Does the Calculator Work?

The calculator uses the shiplap formula:

Where:

• \( \text{Area} \) — Total area to cover (square feet)
• \( \text{Board Width} \) — Width of each shiplap board (feet)
• \( \text{Exposure Factor} \) — The visible portion of each board after installation (typically 0.85)

Explanation: The formula accounts for the overlap between boards, ensuring you purchase enough material to cover your entire area.

3. Importance of Accurate Calculation

Details: Proper calculation prevents material waste and ensures you have enough boards to complete your project without multiple trips to the store.

4. Using the Calculator

Tips: Measure your area carefully in square feet. The exposure factor is typically around 0.85 (meaning 85% of each board is visible after installation).

5. Frequently Asked Questions (FAQ)

Q1: What's a typical exposure factor for shiplap?
A: Most shiplap has an exposure factor between 0.8 and 0.9, with 0.85 being most common.

Q2: Should I add extra for waste?
A: It's recommended to add 10-15% to your total for cutting waste and mistakes.

Q3: How do I measure board width?
A: Measure the actual visible width after installation, not the total board width.

Q4: Can I use this for ceilings and walls?
A: Yes, the calculation works the same for any surface area.

Q5: What if my boards are sold by the piece rather than linear feet?
A: Divide your total linear feet by the length of each board to get the number of pieces needed.
