Notices of Acceptance (NOAs)

Notices of Acceptance are used in hurricane-prone areas to help assure that glazing components or systems have passed appropriate impact and wind cycle tests.

Building code specialists and insurance officials in Miami-Dade County, Florida, helped establish the NOA test standards, working with a new generation of glazing products from science and safety oriented companies including DuPont.

DuPont™ SentryGlas® and Butacite™ safety glass interlayers are widely used in hurricane-resistant windows and commercial glazing systems, and each interlayer has an official NOA on file:

A laminating interlayer is just one element in a finished glass product or framed glazing.  Hundreds of commercial glazing and residential window and door systems have been designed and tested to incorporate DuPont™ SentryGlas® or Butacite® interlayers and meet Miami-Dade codes and related impact glazing standards.
