Lynden Siding What Board and Batten Actually Is
Board and batten is one of the oldest siding patterns in the Pacific Northwest, and it's having a real moment again — especially on farmhouse-style and modern-farmhouse builds around Lynden and the wider Whatcom County countryside. The look is simple: wide vertical panels installed edge to edge, with a narrower strip (the batten) covering each seam. The result is a clean, vertical rhythm that reads as more contemporary than traditional horizontal lap siding, without looking out of place on a barn-style outbuilding or a century farmhouse.
With James Hardie, board and batten isn't a field-built assembly of individual boards nailed up one at a time. It's an engineered panel system — Hardie manufactures the vertical panels and the battens as matched fiber cement components designed to be installed together, which matters more than it sounds like once you get into how this climate treats a wall.
Why the Style Holds Up Differently Than It Used To
Traditional board and batten was often built from solid wood boards that cupped, split, and trapped moisture behind the battens over time — especially in a climate like ours, where driving rain off the Strait and long stretches of damp, low-sun winter give wood siding very little chance to dry out between soakings. Add in the moss and algae growth that Whatcom County's mossy season encourages on any north-facing or shaded wall, and wood board and batten becomes a maintenance project, not a finished exterior.
Fiber cement changes the equation. James Hardie panels are engineered from cement, sand, and cellulose fiber — they don't absorb water the way wood does, they don't provide the organic material that moss and algae feed on the way bare or lightly primed wood can, and they hold their shape instead of cupping or splitting as they move through wet and dry cycles.
HZ5: Built for This Specific Climate
James Hardie makes climate-specific product lines, and the Pacific Northwest falls under their HZ5 engineering zone — formulated for regions with sustained moisture exposure, freeze-thaw cycling, and salt air influence off Puget Sound and the Strait of Georgia. That's not a marketing label; it affects the actual formulation of the cement board so it performs in exactly the conditions Lynden sees: wet fall and winter, damp spring, and a coastal air quality that will slowly degrade lesser materials.
Reveal, Spacing, and Proportion
Board and batten lives or dies on proportion. A few things worth understanding before you pick a look:
- Batten spacing — typically set 12" to 16" on center, though wider spacing reads more modern and tighter spacing reads more traditional/farmhouse.
- Panel reveal — the visible width of the panel between battens; wider reveals show more of the flat panel color, narrower reveals emphasize the vertical batten lines.
- Mixed profiles — board and batten on gables or accent walls paired with Hardie lap siding on the main body is a common, well-proportioned combination, and it lets you use board and batten as an accent rather than committing the whole house to it.
Color: ColorPlus vs. Field Paint
Board and batten shows paint failure more visibly than lap siding does, because the flat panel faces and crisp batten lines highlight fading, chalking, and uneven touch-up in a way that overlapped lap boards can hide. James Hardie's ColorPlus Technology bakes the finish onto the panel at the factory in a controlled environment, which gives more even color and better fade resistance than a field-applied paint job, along with a longer finish warranty. For a style where flat, uninterrupted color is the whole visual point, factory finish is worth the consideration.
Where Installation Quality Actually Shows Up
Board and batten is less forgiving of poor installation than lap siding is, because there's nowhere for a sloppy seam or a misaligned batten to hide.
| Detail | Why It Matters Here |
|---|---|
| Rainscreen / drainage gap | Furring behind the panels lets water that gets past the surface drain and dry, instead of sitting against the wall through our wet months |
| Batten fastening | Battens need to be fastened into framing, not just into the panel below — loose battens work themselves free in wind and driving rain |
| Panel gaps and caulking | Manufacturer-specified gaps and sealant at joints keep water from tracking behind panels during sustained storms |
| Bottom clearance | Proper clearance from grade, decks, and roofing keeps splashback and standing moisture away from the panel edge |
None of this is unique to board and batten, but the style makes mistakes more visible faster — a gap that would be invisible under a lap course is a straight vertical line you'll see from the street.
Warranty and Longevity
James Hardie backs their fiber cement panels with a 30-year non-prorated limited warranty, and ColorPlus finishes carry their own finish warranty separate from the substrate. Both are transferable if you sell the home, which matters more than people expect — a documented siding warranty is a real selling point in a market where buyers are increasingly asking what the exterior is made of and how it was installed.
Is It Right for Your House
Board and batten suits certain architectural styles better than others — farmhouse, modern farmhouse, craftsman with vertical accents, and barn-influenced designs all take to it naturally. On a straightforward ranch or traditional colonial, it may work best as an accent on a gable or porch rather than the whole exterior. It's worth walking the house and talking through where it actually earns its place, rather than defaulting to it because it's trending.
