NFCFS fire station/engine house and bunkhouse going up by Shell Building Systems in Northern California. Premier SIPS on walls and roof on both structures.
In WUI zones like much of Northern California, the envelope spec is not optional. Solid foam core limits oxygen flow within the assembly. Premier SIPS achieve a 1-hour fire-rated assembly per ASTM E119.
If any building has to get the envelope right, it is a fire station.
