Asphalt-Impregnated Wood Board

Asphalt-Impregnated Wood Board - High-Performance Construction Material

Engineered Wood Composite Technology

This specialized building material combines natural wood fibers with asphalt saturation to create a dimensionally stable, moisture-resistant board for demanding construction applications.

Material Composition Advantages

• Premium wood fibers fully impregnated with modified asphalt
• Homogeneous saturation for complete moisture protection
• Available in multiple density grades for different load requirements

Performance Characteristics

• Water resistance: <5% water absorption after 24-hour immersion

• Dimensional stability: <0.5% linear expansion in humid conditions

• Thermal performance: R-value of 1.2 per inch (superior to untreated wood)

Optimal Application Scenarios

1. Below-grade construction: Foundation perimeter insulation

2. Roofing systems: Base layer for built-up roofing

3. Cold storage facilities: Thermal break and vapor barrier

4. Marine construction: Dock fenders and seawall protection
