1. What is the Modwood Decking Calculator?

The Modwood Decking Calculator helps determine the number of composite decking boards needed for a decking project, accounting for material waste during installation.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ N = \lceil \frac{\text{Deck Area}}{\text{Board Length} \times \text{Board Width}} \rceil \times (1 + \frac{\text{Waste Percentage}}{100}) \]

Where:

\( N \) — Number of boards needed
\( \text{Deck Area} \) — Total area to be covered (m²)
\( \text{Board Length} \) — Length of individual boards (m)
\( \text{Board Width} \) — Width of individual boards (m)
\( \text{Waste Percentage} \) — Additional material needed for cuts and waste (%)

Explanation: The formula first calculates how many boards would be needed without waste, then adds a percentage to account for cutting waste and errors.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you purchase enough materials for your project while minimizing excess. This saves money and reduces material waste.

4. Using the Calculator

Tips: Measure your deck area accurately in square meters. Know the dimensions of the Modwood boards you plan to use. Typically, 10-15% waste is recommended for most projects.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical waste percentage for decking projects?
A: For simple rectangular decks, 10% is usually sufficient. For complex designs with many cuts, 15-20% may be needed.

Q2: Should I round up the final number of boards?
A: Yes, the calculator automatically rounds up to the nearest whole board since you can't purchase partial boards.

Q3: Does this calculator account for board orientation?
A: No, this calculator assumes standard installation. For diagonal or herringbone patterns, you may need additional waste percentage.

Q4: Can I use this for other composite decking brands?
A: Yes, the calculation method works for any decking material, but always check the specific board dimensions for your chosen product.

Q5: Should I buy extra boards for future repairs?
A: It's recommended to purchase 1-2 extra boards beyond the calculated amount for potential future repairs, as colors may vary between production batches.
