NEW HAVEN, Conn. - The Bilco Company is pleased to announce that it now offers roof hatches that have received Miami-Dade County’s Notice of Acceptance (NOA). The NOA certifies that Bilco’s standard Type S and NB steel and aluminum roof hatches, including the Enhanced Performance roof hatch for green building applications, conform to high-velocity hurricane zone standards in Miami-Dade County in Florida.

When roof hatches were added to the Florida Building Code’s list of hurricane-resistant products in 2007, Bilco began working with Miami-Dade County Building Code Compliance Office to help develop test protocols for hatches. These tests included high-pressure uplift and downdraft cycling, large missile impact and water intrusion. The company also evaluated laboratories capable of performing such tests.

Type S and NB hatches feature heavy-gauge construction for overall strength as well as fully welded corners on both the curb and cover and full perimeter gasketing for complete weather-tightness. Hatches are equipped with heavy-duty slam latches to ensure that the covers remain closed under these extreme conditions.
