Understanding Board Coverage
Proper board coverage calculation ensures accurate material ordering and efficient installation.
- Board Types Different profiles suit different applications.
- Coverage Area Account for overlaps and waste factors.
- Installation Method Affects material requirements and appearance.
- Waste Factor Include extra for cuts and damaged pieces.
Design Considerations
Pattern
Consider visual impact of board layout.
Moisture
Plan for expansion and contraction.
Ventilation
Ensure proper airflow behind boards.
Fastening
Use appropriate fasteners for material.
Board Type Guide
- Lap Siding Traditional overlapping installation for weather protection.
- Wall Panel Large format panels for quick coverage.
- Shiplap Decorative profile with minimal gaps.
- Tongue and Groove Secure connection for tight seams.
Installation Tips
- Surface Prep Ensure flat, clean mounting surface.
- Starting Level Begin with level starter strip.
- Fastening Pattern Follow manufacturer specifications.
- Finishing Properly seal ends and edges.
