THE SIMPLE MATHEMATICS OF A BALANCED RIDGE VENTILATION SYSTEM
- According to most building codes, you need 1 square foot of ventilation for every 150 square feet of attic floor space.
- For new home construction that includes a vapor retarder, the minimum is 1 square foot of ventilation for every 300 square feet of attic floor space.
- If your vents are split between ridge vents and intake vents, the minimum requirement is also 1 square foot of ventilation for every 300 square feet of attic floor space.
To determine how many feet of net free area you need, use this formula:
|Square feet of attic floor space
|=||Square feet of net free area needed|
|1500 square feet of attic floor space
|=||5 square feet of free are a needed|
- To determine how many feet of ShingleVent® II, Multi-Pitch FilterVent® or VenturiVent Plus™ you need, use this formula:
- 1/2 net free area x 144 ÷ 18 = feet of ridge vent needed
- For example: 2.5 (based on net free area of 5 square feet) x 144 ÷ 18 = 20 feet of ridge vent needed
- To determine how many feet of Air Vent soffit vents you need, use this formula:
- 1/2 net free area x 144 ÷ 9 = feet of soffit vent needed
- For example: 2.5 (based on net free area of 5 square feet) x 144 ÷ 9 = 40 feet of soffit vent needed
- The following charts may be used to:
- 1. Determine how much net free area is needed to satisfy FHA requirements.
- 2. Balance your ridge vent system.
DETERMINING VENTILATION REQUIREMENTS
|Min. Net Free Area Required
(if balanced between intake and exhaust)
Note: ShingleVent II and Multi-Pitch FilterVent provide 18" of net free area per linear foot.
INSTALLING A BALANCED RIDGE VENT SYSTEM
- Measure the square footage of the attic (length x width).
- Measure the length of the ridge.
- Refer to the chart above for required net free area and minimum length of ridge for attic square footage.
- Note: In most cases, the length of the ridge balanced with the same net free area of intake vents will satisfy FHA minimum standards and most building codes.
- Use the chart below to calculate the amount of intake vents that should be installed to balance your ridge vent system.
- Always install ridge vents from end to end across the entire ridge for best appearance and to provide maximum ventilation area.
- Hip roofs, dormers and T- or L-shaped roofs may require a specially designed ventilation system. For information, request a copy of Air Vent's Principles of Attic Ventilation.See Contact Us.
