Birch Bay Siding What Board and Batten Actually Is
Board and batten is one of the oldest siding patterns in North America, and it has had a real resurgence over the last decade — you'll see it on new farmhouse-style builds, on modern boxy remodels, and increasingly as an accent on homes throughout Whatcom County that would otherwise be sided in lap siding alone. The pattern is simple: wide vertical panels (the "boards") are installed with narrow strips (the "battens") covering the seams between them. The result is a strong vertical line, deep shadow lines from the battens, and a look that reads as both traditional and contemporary depending on the trim and color choices around it.
In fiber cement, board and batten is not a fringe product. James Hardie makes it as a purpose-built panel system, and it holds up to the coastal conditions around Birch Bay — salt air, driving rain, and a long moss season — in a way that other vertical siding materials often don't.
Why Vertical Siding Behaves Differently Than Lap Siding
Horizontal lap siding is designed so every board sheds water onto the board below it, working with gravity the whole way down the wall. Vertical siding has to be detailed more carefully, because water runs straight down the face of the panel rather than being broken up and redirected at each course. That's not a knock on board and batten — it's just a reason the installation details matter more than they do with lap siding.
The two things that make or break a vertical fiber cement installation are the underlying drainage plane and the way the panel-to-panel joints are handled. Done right, board and batten sheds water as well as any siding style on the market. Done with shortcuts, it's one of the faster ways to get moisture behind a wall, especially in a climate that sees as much sideways rain off the Strait as this one does.
The Rainscreen Question
A rainscreen gap — a drainage space between the back of the siding and the weather-resistive barrier, usually created with vertical furring strips — lets any water that gets past the siding drain and dry out instead of sitting against the sheathing. It's not strictly required by code in every jurisdiction, but on a Whatcom County coastal property, we treat it as standard practice rather than an upgrade, particularly on board and batten where the panel seams are more exposed to wind-driven rain than a lapped horizontal joint.
Hardie's Board and Batten Product Options
James Hardie offers vertical siding in a few different forms, and the right one depends on the look you're after and the wall it's going on.
| Product | What It Is | Best Suited For |
|---|---|---|
| HardiePanel Vertical Siding | Large-format flat panels installed vertically, with battens covering the seams | Full board and batten walls, farmhouse and modern facades |
| HardiePanel with HardieTrim Battens | Panel system paired with dedicated trim boards sized and profiled to work as battens | Consistent batten spacing and clean shadow lines |
| HardieTrim Boards (as accents) | Trim-only vertical accenting over lap siding, such as gable ends or a single feature wall | Mixed-material facades — vertical accent with lap siding elsewhere |
Most of the board and batten work we do is a mix of HardiePanel for the field and HardieTrim boards ripped and installed as the battens, which gives us control over batten width and spacing rather than relying on a fixed factory pattern.
Getting the Proportions Right
Board and batten lives or dies on proportion. Panel width, batten width, and batten spacing all interact, and getting them wrong is the difference between a facade that looks intentional and one that looks like an afterthought.
- Batten spacing: Most residential board and batten looks best with battens spaced 12 to 24 inches on center. Wider spacing reads more modern and minimal; tighter spacing reads more traditional and cottage-style.
- Batten width: Standard battens run 1x2 to 1x4 (nominal). Thinner battens give a crisper, more contemporary look; wider battens create deeper shadow lines and a heavier, more rustic feel.
- Consistency around openings: Batten spacing should be planned around windows and doors before the first panel goes up, not adjusted on the fly, so you don't end up with an odd-width sliver of panel next to a window trim.
- Corner and trim relationship: Batten width should generally relate to the corner trim width so the whole facade reads as one system rather than two mismatched patterns colliding at the corners.
This is the kind of layout work that happens before a single panel is cut, and it's the reason we walk the elevation with the homeowner and mark out the batten layout before installation starts.
Where Board and Batten Works Best on a Home
Full-Wall Application
An entire home sided in board and batten is a strong, deliberate look — common on farmhouse-style new builds and full re-sides where the homeowner wants a clean break from a more conventional lap-sided look. It reads well on both single-story ramblers and taller two-story homes, though on taller walls the batten spacing and any horizontal trim bands (belly bands between floors) matter even more for keeping the proportions from feeling too busy or too plain.
Accent Application
The more common use we see is board and batten as an accent — gable ends, a front entry feature wall, a dormer, or a porch gable — paired with HardiePlank lap siding on the rest of the house. This is often the better choice on a remodel budget, since it concentrates the visual interest where it matters most (the entry, the street-facing gable) without re-siding the whole envelope in the more labor-intensive vertical pattern.
Color and Finish Considerations
Board and batten's vertical lines and deep shadow gaps show color and light differently than lap siding does. A few things worth knowing before picking a color:
- Darker ColorPlus finishes make the shadow lines from the battens more pronounced and dramatic — a good fit for a modern farmhouse look.
- Lighter finishes soften the shadow lines and read cleaner and more minimal, which suits contemporary designs.
- A common and effective combination is board and batten in one ColorPlus tone with the battens or trim in white or a contrasting neutral, which sharpens the vertical lines further.
- ColorPlus factory finish matters as much here as anywhere else on the house — field-painted cut edges should be sealed with Hardie's touch-up product, and this is worth confirming with any contractor bidding the job, board and batten or not.
What Correct Installation Looks Like
A handful of details separate a board and batten job that will still look good in fifteen years from one that starts showing problems in three:
- Proper drainage plane and, on most coastal walls in this area, a rainscreen gap behind the siding
- Correct fastener type, spacing, and embedment per Hardie's published installation instructions — this is not a place to freehand it
- Battens fastened independently of the panel beneath them where required, not just face-nailed through both layers into the sheathing without regard to expansion
- Proper clearance at the bottom of the wall — siding should sit above grade, decks, and roof lines per Hardie's minimum clearances, which keeps splashback and standing moisture away from the panel edges
- Sealed and flashed panel joints, window and door openings, and any horizontal trim bands
- Factory-cut edges used wherever possible, with any field cuts sealed per Hardie's specification
None of this is exotic. It's published in Hardie's installation instructions and it's what their warranty is conditioned on. But it takes longer to do correctly than to do quickly, and that time is where corners tend to get cut on a rushed bid.
Cost Factors to Understand Before You Bid It Out
Board and batten generally costs more per square foot than a straightforward lap siding install, for reasons worth understanding rather than just accepting as a number on a quote:
| Factor | Why It Adds Cost |
|---|---|
| Batten installation | Every batten is a separate piece to measure, cut, and fasten — roughly double the individual components of a lap job |
| Layout planning | Batten spacing has to be planned around windows, doors, and corners before installation, which takes more up-front time |
| Cutting and waste | Vertical panels and ripped battens generate more offcuts than lap boards, especially around openings |
| Rainscreen detailing | Furring strips and drainage detailing add material and labor, particularly important on an exposed coastal wall |
None of these are reasons to avoid board and batten — it's a durable, good-looking system when installed right — but they're reasons a board and batten bid should look different, and usually higher, than a same-size lap siding bid, and why a bid that doesn't reflect that is worth asking questions about.
Board and Batten on a Birch Bay Home Specifically
Homes along the Birch Bay waterfront and the surrounding Whatcom County shoreline take a steadier beating from the weather than homes further inland — onshore wind carries salt air against the siding, storms off the Strait of Georgia bring driving rain at the wall rather than straight down, and the shaded, damp stretches of the year here support a long moss season on roofs, decks, and north-facing siding. Vertical siding's exposed seams and shadow-line gaps make correct flashing and drainage detailing more important here than in a drier, calmer inland climate, and it's also why ColorPlus factory finish — rather than field paint — earns its keep on a coastal property that gets more UV and salt exposure than most.
None of that is a reason to avoid board and batten in this area. It's a reason to be selective about who installs it and how.
