Dutch Lap vs. Clapboard
You decide on vinyl siding.
Then the contractor asks:
Clapboard or Dutch lap?
Both run horizontally.
But the profile creates a different shadow and architectural effect.
What Is Clapboard?
Clapboard creates the appearance of traditional overlapping horizontal boards.
It has a relatively straightforward face profile.
What Is Dutch Lap?
Dutch lap includes a recessed or concave area near the top of each course.
Gentek describes Dutch lap as a variation of clapboard with a distinctive notch that creates stronger shadow lines.
Which Looks More Traditional?
Both can work on traditional homes.
Dutch lap often creates:
- Deeper visual lines
- More pronounced shadow
Clapboard can feel:
- Simpler
- Cleaner
- More understated
Does One Perform Better?
Do not choose based on profile alone.
Performance depends on:
- Product line
- Panel thickness
- Locking system
- Installation
CertainTeed offers both clapboard and Dutch-lap configurations within the same siding families.
Profile Changes the Look. Installation Controls the Performance.
