SNOW LOADS & SEISMIC ENGINEERING

Alaska experiences some of the highest snow loads and most active seismic zones in North America. Polar Plank packages are structurally calculated by licensed Alaska Professional Engineers to guarantee your home stands unyielding through record blizzards and major earthquakes.

ALASKA ROOF SNOW LOAD BENCHMARKS (PSF)

Ground snow loads in Alaska vary drastically by microclimate and elevation. Our heavy timber roof rafters, ridge beams, and purlin systems are calculated to match or exceed your exact building borough requirements:

Kenai / Soldotna60–70 PSFKPB Standard
Anchorage / Mat-Su50–70 PSFValley Standard
Fairbanks / Interior50–60 PSFDry Cold Snowpack
Seward / Valdez / PWS100–150+ PSFExtreme Heavy Coastal
EARTHQUAKE RESILIENCE

SEISMIC ZONE 4 TIE-DOWNS

Following the 1964 Great Alaska Earthquake and the 2018 Anchorage 7.1 magnitude quake, building codes enforce strict lateral resistance. Polar Plank's interlocking wall panels function as rigid shear diaphragms that absorb and dissipate ground accelerations without cracked drywall or detached timber corners.

PERMIT COMPLIANCE

ALASKA PE STAMPED PLANS

Building departments in Anchorage, the Mat-Su Borough, and other jurisdictions require stamped engineering plans. Polar Plank provides structural calculation packets and stamped drawings ready for submission with your building permit application.
