1. What is Shiplap Exposure?

Shiplap exposure refers to the visible portion of each board after installation, calculated by subtracting the overlap from the total board width. Proper exposure ensures consistent appearance and weather protection.

2. How Does the Calculator Work?

The calculator uses the shiplap exposure formula:

\[ exposure = board\_width - overlap \]

Where:

Explanation: The formula calculates how much of each board will remain visible after accounting for the overlap with adjacent boards.

3. Importance of Proper Exposure

Details: Correct exposure ensures uniform appearance, proper water shedding, and structural integrity of the shiplap installation.

4. Using the Calculator

Tips: Enter board width and overlap in inches. Both values must be positive numbers, and overlap should be less than board width.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical shiplap exposure?
A: Common exposures range from 5 to 7 inches, but this depends on board width and desired appearance.

Q2: How does exposure affect installation?
A: Greater exposure means fewer boards needed but may compromise weather protection. Less exposure provides better protection but requires more material.

Q3: Should exposure be consistent for all boards?
A: Yes, maintaining consistent exposure is crucial for a uniform appearance and proper function.

Q4: How does board width affect exposure?
A: Wider boards allow for greater exposure while maintaining sufficient overlap for weather protection.

Q5: What's the minimum recommended overlap?
A: Typically 1-2 inches for proper weather protection, but consult manufacturer recommendations.
