What Is Shiplap? History, Uses, Installation, and Design Ideas
Add depth and character to walls with a simple woodworking technique.
What Is Shiplap?
Shiplap is a style of wood paneling characterized by long, horizontal boards that overlap with rabbet joints—grooves cut into the edges that let the boards fit tightly together. Traditionally used as siding for building exteriors, shiplap’s hallmark is its watertight seal and smooth, uniform surface. Today, shiplap is widely used for both interior and exterior walls, lending a distinctive texture and rustic charm to any space.
Shiplap’s popularity stems from its versatility, clean lines, and ability to add both warmth and architectural interest in homes of many styles, from farmhouse to modern minimalist.
A Brief History of Shiplap
While shiplap is a trending design feature in homes today, its roots go back centuries. Originally developed for shipbuilding, the overlapping boards created water-resistant partitions critical for wooden vessel hulls. Over time, this technique made its way onto homes—first as practical exterior siding meant to keep out wind and rain, and later as a stylish option for interior walls.
Traditional shiplap was typically crafted from sturdy woods like pine or cedar, favored for their natural durability and weather resistance. The same basic approach—boards milled with rabbet joints for overlapping—remains unchanged. What has evolved is the creative use of shiplap, with homeowners bringing this once utilitarian material indoors for its aesthetic appeal.
How Shiplap Is Made
Shiplap boards are manufactured with two opposing rabbet joints: notches cut into both the top and bottom of the board edges. When installed, the notches on each board overlap perfectly, resulting in a flat face and a shallow groove at each meeting point.
Common materials for shiplap include:
- Pine: Often used for its affordability and ease of installation.
- Cedar: Prized for its natural resistance to moisture and insects.
- Vinyl: Offers a low-maintenance, synthetic option for exteriors.
- Fiber cement: Durable and resistant to elemental damage.
- Cypress and poplar: Used in specialty applications for aesthetic or performance qualities.
While shiplap is commonly installed horizontally, vertical installs are also possible for certain design looks, particularly in accent walls or bathrooms.
Shiplap vs. Other Types of Wood Paneling
| Feature | Shiplap | Tongue & Groove | Board & Batten |
|---|---|---|---|
| Overlapping Boards | Yes, with rabbet joint | No, boards interlock without overlap | No, battens cover seams |
| Typical Installation Direction | Horizontal, sometimes vertical | Usually horizontal or vertical | Vertical boards with horizontal battens |
| Seal Quality | Tight & weatherproof | Excellent interlocking seal | Varies; battens improve water resistance |
| Visual Effect | Smooth, shallow grooves | No visible grooves | Prominent vertical seams |
Where Can Shiplap Be Used?
Shiplap is incredibly flexible for both interior and exterior design. Here’s where you’ll commonly find it:
- Exterior Siding: Traditional shiplap served as siding for barns, sheds, and homes, particularly where protecting against harsh weather mattered.
- Interior Walls: Its clean lines and texture make shiplap a favorite for living rooms, bedrooms, kitchens, and bathrooms, often as an accent wall.
- Ceilings: Used to add depth and dimension, especially in open-concept or cottage-style interiors.
- Entryways and Mudrooms: Durable and visually appealing, shiplap resists wear and tear in high-traffic zones.
Benefits of Shiplap
Shiplap offers several practical and aesthetic benefits:
- Durability: The overlapping joint design helps resist warping and cracking, enhancing the lifespan of both interior and exterior walls.
- Weather Resistance: Properly installed shiplap forms a water- and air-tight barrier, protecting structures from rain and wind.
- Thermal Efficiency: The layered boards add a degree of insulation, helping regulate interior temperatures.
- Minimal Maintenance: Occasional cleaning and repainting or resealing keep shiplap looking its best.
- Customizable Style: Shiplap takes paint or stain well and can be adapted for rustic, modern, or traditional looks.
- DIY-Friendly: Homeowners with basic carpentry skills can install shiplap walls without specialized tools.

Drawbacks and Considerations
Despite its advantages, shiplap also has some potential drawbacks:
- Accumulation of Dust and Dirt: The grooves between boards may collect dust and require regular cleaning.
- Proper Installation Required: Incorrect installation can lead to gaps, warping, or poor weather sealing over time.
- Design Compatibility: Shiplap’s rustic appearance might not suit every architectural style or interior design scheme.
- Susceptibility to Moisture (Indoors): In humid environments or poorly ventilated spaces, wood shiplap can be prone to expansion or mold without proper treatment.
How Is Shiplap Installed?
Shiplap installation is straightforward but must be done carefully for lasting results.
- Surface Preparation
- Ensure the underlying wall is clean, dry, and structurally sound.
- Remove loose paint, wallpaper, or debris.
- Board Placement
- Begin at the bottom edge of the wall.
- Lay the first shiplap board horizontally, using a level to ensure straightness.
- Fasten the board to wall studs using nails or screws.
- Overlap Boards
- Place the next board above the preceding one, overlapping rabbet joints for a tight fit.
- Continue upward, maintaining consistent spacing for aesthetic effect.
- Finishing
- Fill nail holes as needed.
- Paint or stain boards for the desired appearance.
For best results, consider seeking professional help if you’re unsure about wall structure or moisture protection.
Design Ideas for Using Shiplap
- Classic White Shiplap: Recreate the popular cottage, farmhouse, or coastal look with crisp white boards for a breezy, open feel.
- Bold Colors: Paint shiplap in jewel tones, charcoal black, or navy blue to create dramatic accent walls.
- Stained or Rustic: Let natural wood grain shine by staining shiplap, perfect for rustic lodges or cabins.
- Modern Vertical Shiplap: Install boards vertically for a modern, elongating effect—ideal for small spaces or contemporary homes.
