1. What is the Decomesh Soffit Vent Calculator?

The Decomesh Soffit Vent Calculator estimates the required vent area for proper attic ventilation using Decomesh products. It calculates based on roof area and the specific Decomesh factor for the product being used.

2. How Does the Calculator Work?

The calculator uses the Decomesh vent area formula:

Where:

• \( \text{Roof Area} \) — Total roof area in square feet
• \( \text{Decomesh Factor} \) — Product-specific efficiency factor (typically 0.5 for standard Decomesh)

Explanation: The formula accounts for the 1:300 ventilation ratio (1 sq.ft of vent area per 300 sq.ft of roof area) adjusted by the Decomesh product's specific efficiency.

3. Importance of Proper Ventilation

Details: Proper soffit venting is crucial for preventing moisture buildup, reducing heat accumulation in summer, and maintaining roof durability. Decomesh products provide insect-resistant ventilation while maintaining airflow.

4. Using the Calculator

Tips: Enter total roof area in square feet and the specific Decomesh factor (typically 0.5 unless using a different product). The calculator will determine the required vent area.

5. Frequently Asked Questions (FAQ)

Q1: What is the 1:300 ventilation ratio?
A: This is the standard ratio of 1 square foot of vent area for every 300 square feet of attic floor space (roof area).

Q2: What are typical Decomesh factors?
A: Standard Decomesh has a factor of 0.5, but this may vary by product type - always check manufacturer specifications.

Q3: How do I measure roof area?
A: Calculate the length × width of each roof plane and sum them together. For complex roofs, consider professional measurement.

Q4: Should vents be evenly distributed?
A: Yes, vents should be evenly distributed along the soffit to prevent localized moisture issues and ensure proper airflow.

Q5: Can I use this for other vent types?
A: This calculator is specific to Decomesh products. Other vent types may require different calculations.
