No. ICC-ES (AC364) is a test to prove an automatic flood vent opens automatically to allow flood waters to enter and exist. This is a requirement for flood vents that automatically open and closes. Our vents stay in an open position all of the time and do not require this test. The criteria for this test is attached and titled “ICC-ES (AC364)”. Also, attached is an example of the evaluation report “ESR-2074” showing results of the test.

No. TB 1 / August 2008 explains on page 19 that it is unacceptable to “have detachable solid covers that are intended to be manually installed over the opening in cold weather, because they do not allow for the automatic entry and exist of floodwaters when the cover is in place.”

Yes. Title 44 of the Code of Federal Regulations, in Section 60.3(c) (5), states: “Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters.”

Yes. NFIP’s flood insurance requirements boil down to this: You must have at least one square inch of opening in the foundation wall for every square foot of house’s enclosed area. The bottom of the flood vent opening must be less than 12 inches above the ground. Two vents per enclosed area, on different exterior walls.

Not if the flood vent package is labeled with the opening size. TB 1 / August 2008, page 20 sates: “Manufacturers of devices intended for use as standard air vents typically indicate the number of square inches that each device provides for air flow (either stamped into the metal frame or noted on the packaging).

As established by the U.S. Congress, the sale of flood insurance under the NFIP is subject to the rules and regulations of FEMA. FEMA Division has elected to have State-licensed insurance companies’ agents and brokers sell flood insurance to consumers. State regulators hold the insurance companies’ agents and brokers accountable for providing NFIP customers with the same standards and level of service that the States require of them in selling their other lines of insurance.Private insurance companies participating in the Write Your Own (WYO) Program must be licensed and regulated by States to engage in the business of property insurance in those States in which they wish to sell flood insurance.

No. TB 1 / August 2008 defines the 3″ opening size on page 26 as: “Engineered openings are to be not less than 3 inches in any direction in the plane of the wall. This requirement applies to the hole in the wall, excluding any screen, grate, grille, louvers or devices that may be placed in or over the opening.” Title 44 of the Code of Federal Regulations, in Section 60.3(c) (5), states: “Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters.” The 3 inch rule is for the hole in the wall not the space between the louvers or screens.

No. federal policy does not allow FEMA to approve, endorse, certify or recommend any products. While a product may be in compliance with FEMA design guidance, any language from manufacturers stating their product is “FEMA approved” or “FEMA certified” is incorrect.  Non-engineered flood vents do not need a certification. Engineered flood vents require certifications for the state they will be installed.  Companies  claiming that their flood vent is the only “legal” flood vent is also incorrect.  Our Engineered Flood Vents offer competitive coverage area, for an affordable price, compared to other engineered flood vents on the market.

The NFIP’s Community Rating System (CRS) recognizes community efforts beyond the NFIP minimum standards by reducing flood insurance premiums for the community’s property owners. The discounts may range from 5 to 45 percent. The discounts provide an incentive for new flood mitigation, planning, and preparedness activities that can help save lives and protect property in the event of a flood.

The CRS Coordinator’s Manual, additional CRS publications, and software may be ordered online or by writing, phoning, or faxing a request to the NFIP/CRS. Contact information is listed in the “Additional Reading” section at the end of the booklet. All publications are free, and the computer software for completing the application is also available at no charge.
