Q: |
How does the external wind deflector work? |
|
A: |
In high wind areas, water hits the wind deflector, and is then directed away, going over the ridge vent. |

|
Q: |
Are wind deflectors neccessary? |
|
A: |
Not in all areas. Moisture and hot air will rise naturally without a deflector. However, in high wind or coastal areas, they are neccessary to help prevent water or snow from entering in the house through the vent. |

Q: |
What prevents bugs from entering the attic? |
|
A: |
A glass fiber (filter system material) prevents bugs from getting inside the attic. Also, airflow escaping will assist to keep out unwanted debris. |

Q: |
How can I prevent ice dams? |
|
A: |
The WRV in conjunction with adequate soffit vents will help keep your attic cooler. With proper insulation and ventilation you will have less heat loss through your ceiling so the snow will not melt and therefore ice dams will not form. |

Q: |
Will the WRV deteriorate? |
|
A: |
The Wood Ridge Vent Co. Inc. applies two coats of non-toxic paint to keep the moisture from entering the CDX, exterior glue plywood. The glass fiber also helps keep the moisture from getting on the wood. |

Q: |
Is there an end cap to go with the WRV? |
|
A: |
Each piece of 8ft. section of the WRV on one end, has an end block which closes once the vent is placed on the ridge. |
