What is Struc 1 plywood?

By KC Eisenberg

If you're considering a seismic upgrade to your home, or building a new structure in a quake-prone zone, you'll likely want to use Struc 1 plywood. But what is Struc 1 plywood and why does it matter for seismic building performance?

5-ply Structural 1 plywood, also known as Struc 1, is the best kind of plywood to use for seismic resilience because it is made of Douglas fir throughout the sheet of plywood. This gives Struc 1 plywood more strength than typical plywood, which is made with softer, weaker cores of pine or white fir.

Sustainable Northwest Wood aims to offer high-quality plywood at an excellent price. This is why we stock 5-ply 1/2" Struc 1 CDX plywood -- which is, of course, also FSC Certified and contains no added urea formaldehyde (NAUF)

All of our 1/2" CDX is Struc 1 rated. We've got it in stock and ready to go for your seismic retrofit and other construction projects. Please contact us today for current pricing.
