- Crane time adds significant duration.
Polyurethane installation is 3 to 8 times faster than solid wood.
Skill requirements
Polyurethane:
- Standard carpentry skills.
- No specialized training required.
- Beginner crew can install with basic guidance.
Solid wood:
- Advanced carpentry skills.
- Specialized training often required.
- Experienced crew needed for quality installation.
Polyurethane installation requires less skill than solid wood.
Substrate requirements
Polyurethane:
- Standard cleat mounting per substrate.
- Lightweight reduces substrate load requirements.
- Can mount to most substrates with appropriate cleats.
Solid wood:
- Engineered mounting for heavy loads.
- May require additional structural support.
- Substrate must support significant weight.
Polyurethane installation has simpler substrate requirements.
Durability comparison
Dimensional stability
Polyurethane:
- Closed-cell structure doesn't absorb moisture.
- No swelling or shrinking from humidity.
- No warping, cupping, or twisting.
- Maintains dimensions over decades.
Solid wood:
- Hygroscopic material absorbs and releases moisture.
- Swells and shrinks with humidity changes.
- Warps, cups, and twists over time.
- Dimensions change over the building's life.
Polyurethane has significantly better dimensional stability.
Finish durability
Polyurethane:
- Factory finish under controlled conditions.
- UV-stabilized options available.
- Chemical-resistant options for harsh environments.
- Finish maintained with minimal care.
Solid wood:
- Finish applied on-site or at the shop.
- UV degradation without protection.
- Chemical resistance varies by finish.
- Finish requires periodic maintenance.
Polyurethane finishes are more consistent and durable.
Biological resistance
Polyurethane:
- No organic content for biological growth.
- No rot, mold, or insect damage.
- Stable in humid environments.
- No biological degradation over time.
Solid wood:
- Organic content supports biological growth.
- Susceptible to rot, mold, and insects.
- Requires treatment for humid environments.
- Biological degradation possible over time.
Polyurethane has superior biological resistance.
Long-term performance
Polyurethane:
