What EN 13561 Class 2 vs Class 3 means for U.S. projects
Industry news: how European wind classes map to the Beaufort numbers on Shadesology spec sheets.
Why we print both
Solaris cassette lists Beaufort 6 (EN 13561 Class 3). Open lateral-arm is Class 2. Specifiers who work both sides of the Atlantic asked for both numbers. Pair this with the Learning Center Beaufort article when writing a bid.
Questions people ask
- Is EN 13561 required in the U.S.?
- Not as a code, but it is a useful independent wind class. We still design to local IRC/IBC and Florida NOA where required.
