Study Notes
Introduction to Wood
- Wood is a common construction material
- Classifying, selecting, and using wood correctly is challenging due to variations in species and growth/seasoning defects
Advantages of Wood
- Strong in proportion to its weight
- Easily worked and shaped
- Excellent thermal insulator
- Abundant and renewable resource
- Does not degrade if properly handled
Wood Properties
- Strong and durable
- Lightweight
- Easy to work and fasten
- Aesthetically pleasing
Classifications of Wood
- Softwood: comes from cone-bearing needle-leaved trees
- Hardwood: comes from broad-leaved deciduous trees
Wood Structure
- Sapwood: the lighter colored outer layer of the wood
- Heartwood: the darker colored inner layer of the wood
- Bark: the protective outer covering of the tree
Wood Defects
- Compression wood
- Decay
- Pitch pocket
- Shake
- Mineral streaks
- Mold and staining fungi
- Knots
- Cross grain
Wood Processing
- The process of transforming raw logs into usable lumber
Wood Surfaces
- Face: the primary surface of a piece of lumber
- Edge: the side of a board
- End: the cut edge of a piece of lumber
Lumber
- Lumber: term for wood after sawing/slicing into boards, planks, sticks for commercial purposes
Some Definitions
- Surfaced/dressed lumber: planed lumber with at least one smooth side
- S2S (two-sided) surfaced lumber: has smooth surfaces on two sides
- S4S (four-sided) surfaced lumber: has smooth surfaces on all four sides
- Rough lumber: unplaned lumber
Lumber Dimensions
- Timber: pieces of lumber five inches or more in their smallest dimension
- Plank: wide pieces of lumber; 2-5 inches thick
- Board: pieces of lumber under 1.5 inches thick; at least 4 inches wide
- Flitch: thick pieces of lumber
- Slab: roughly cut lumber; surfaces tangent to wood rings of the log
Measuring Wood
- Board foot (bd-ft): a unit of measure representing one square foot of wood, one inch thick (144 cubic inches)
- Formula for calculating board feet: (Thickness in inches x Width in inches x Length in feet) / 12
Examples of Calculations
- Various example calculations demonstrating how to determine total cost of lumber, given different quantities, prices, and sizes of lumber.
