What is Nickel Gap Siding and How It Differs from Shiplap
Nickel gap siding is a rising favorite for homeowners who want clean lines, modern charm, and enhanced curb appeal. Known for its crisp, uniform spacing, nickel gap siding is a stylish and durable option for any Midwest home.

What is Nickel Gap Siding?
Nickel gap siding is a kind of outside siding. Each board has a small, even space between them, about the width of a nickel. This subtle shadow line gives homes a sharp, polished look that enhances curb appeal.
For exterior applications, you can install nickel gap boards horizontally or vertically, depending on the style you aim for. Originally used in coastal homes, today it is popular in everything from rustic farmhouses to sleek modern builds. Available in both natural wood and engineered options, nickel gap offers flexibility to match any home style.
Benefits of Nickel Gap Siding
- Strong visual appeal: clean, uniform lines create a high-end look.
- Versatile installation: works horizontally or vertically on a range of architectural styles.
- Material variety: available in natural wood, cedar siding, and durable LP SmartSide boards.

Difference Between Shiplap and Nickel Gap Siding
Though nickel gap siding and shiplap panels are often compared, they have important differences.
What is Shiplap Siding?
Shiplap siding uses boards that overlap at the edges with a rabbet joint, creating a tight, weatherproof seal. Shiplap panels were once used for barns and sheds. Now, they are popular in both interior and exterior design because of their rustic charm.
Benefits of Shiplap Siding
- Classic charm: adds a warm, traditional look.
- Weather protection: overlapping joints help keep out moisture.
- Affordability: shiplap panels are often less expensive than other decorative sidings.
Nickel Gap vs. Shiplap: Key Differences
- Design: shiplap overlaps; nickel gap boards are installed with a uniform space.
- Visual appeal: nickel gap offers a cleaner, more contemporary look compared to the rustic charm of shiplap.
- Installation: nickel gap requires precise spacing, while shiplap’s overlap design is a bit more forgiving.
- Maintenance needs: both can be easy to care for if sealed well. However, engineered nickel gap products are more durable.
Materials: Wood, Cedar, and LP Boards
The material you choose for nickel gap siding can impact durability, appearance, and maintenance.
Natural Wood Siding
Offers unmatched beauty and authenticity but requires regular sealing or staining to prevent weather damage.
Cedar Siding
Known for its natural resistance to insects and rot, cedar is a premium option that ages gracefully. It enhances the exterior with its rich color and grain patterns.
LP SmartSide
These engineered wood boards mimic the beauty of natural wood while offering increased resistance to moisture, termites, and impact. LP nickel gap boards come pre-primed and prefinished, helping reduce maintenance requirements significantly.

Installation Process for Nickel Gap Siding
Proper installation is crucial to achieving the signature nickel gap look. Here is a general overview:
- Surface preparation: ensure the exterior wall is dry, smooth, and covered with a weather-resistant barrier.
- Starter board placement: install your first board level and secure, whether horizontally or vertically.
- Spacing: use consistent spacers (nickel-sized) between boards for a uniform gap. Some products have built-in spacers to simplify the process.
- Fastening: attach the boards securely, nailing through the tongue or face depending on the board style.
- Finishing touches: caulk edges where needed and apply paint or stain unless using pre-finished boards.
For optimal results, especially with exterior siding, we highly recommend professional installation. Proper technique ensures your siding not only looks beautiful but also stands up to the elements for years to come.
