SIPs for High Elevation and Heavy Snow Loads

laurens88 | Posted in General Questions on

We are looking to build a basic ~500sq ft ADU in Truckee, CA. Snow load 182lbs per sf. We are exploring using SIPS or purchasing a SIPS panelized kit. Does anyone know of any examples of SIPS being used in small construction in high elevations?

Thank you!

    I have done SIP plans at 7,000 ft elevation with 125 lbs snow load. It is likely with the small footprint you will want too many windows & doors, that will be a problem for the SIPS lateral capacity for earthquakes. Part of the snow load is carried into the seismic calculation. A plywood shearwall double stud wall will be easier to engineer & build for lateral & gravity loads- then you can do a SIP roof.
