Is there something new here? Quick read it's nothing new. Even the spec section is old.
Actually it's not an alternate IMHO. Meets the same test standard as other traditional materials used for rated walls. If the AHJ would allow sheetrock for example based on a UL listing then they would also have to accept WS heads. Even further one could use them in an otherwise unsprinklered building.

The ICC Evaluation Service has released an approval and design document for providing window sprinklers as an alternate to fire rated assemblies in the IBC.
