When you’re building in wildfire zones — especially in California — there’s really no room for guesswork. Code compliance is strict for a reason. But a lot of what’s on the market sacrifices appearance just to meet fire regulations. That’s not what Shakertown is about.
Shakertown’s Dolly Varden siding system gives builders and homeowners a product that hits both marks: fully certified WUI compliance and the natural beauty of real wood. It’s one of the few genuine wood systems out there that carries full approval for both wall siding and soffit applications in WUI zones.
The Dolly Varden panels have been tested and officially listed by the California State Fire Marshal. Their wall panels carry listing #8140-2032:0003, approved under SFM 12-7A-1 for exterior walls. For soffits, they’ve got listing #8160-2032:0004 under SFM 12-7A-3. Even the Craftsman Shingle Panel is fully certified with its own listing. These aren’t conditional approvals — they’re fully documented, state-recognized listings that are ready for plan submittals and inspections.
What makes Dolly Varden stand out isn’t just the certification, though. Each panel is built with a 6-ply laminated system using clear vertical grain Western Red Cedar, Hemlock, or Fir. The layers are bonded with exterior-grade adhesives that hold up to extreme moisture, temperature swings, and everything you expect in wildfire zones. They meet full PS 1-22 exterior weathering standards, so there’s no constant worry about panels cupping, warping, or failing under long-term exposure.
Dolly Varden panels come in both Micro-V (Eased Edge) and Fine Line (Nickel Gap) profiles, and the lengths are available in random lengths ranging from 4’, 16′ and 20’. They’re available factory prefinished or ready for field stain, depending on the project.
The key advantage of Dolly Varden is that it simplifies WUI compliance. Builders aren’t trying to piece together multiple products to meet soffit, wall, and eave requirements. With one system, everything is covered — Cedar, Hemlock, or Fir— and it’s all officially approved. When permit time comes, the documentation is in place, and inspections go smoothly.
For anyone involved in WUI construction, that alone saves time, frustration, and cost.
All of the certification paperwork is available and ready if needed for any upcoming projects.
