• Wood is considered as one of the oldest building materials used by man along with masonry.
• Wood is recently replaced by modern construction methods such as steel and concrete as the primary type of material in building construction, but it still remains relevant for both aesthetics and structural reasons.
• Plastic is a relatively new building material that has various classifications and uses.
• Some physical characteristics of plastic make it a suitable alternative material for metal, wood, and concrete depending on the need.
• PVC Ceilings are used in ceilings.
• Polystyrene Insulation is used in insulation.
• Polyethylene Pipe is used in flooring, siding, gutters, window frames, insulation, piping, ceiling.
• Polycarbonate Sheet is used in siding, windows, and roofing.
• Wood refers to the tough fibrous cellular substance that makes up most of the stems, branches, and trunk beneath the bark.
• Wood used in the construction industry is characterized by its strength, durability, light weightiness, and easy to work.
• Wood provides natural beauty and warmth to the senses.
• A wood that is approved for use as a building is referred to as timber.
• Wood is generally classified into two categories: Hardwood and Softwood.
• Softwood refers to coniferous woods that are considered evergreen such as pines, fir, and spruce.
• Hardwood refers to broad-leaved trees such as maple, cherry, oak.
• Bark is the hard outer covering of wood plants.
• Phloem, also known as the inner bark, provides the circulation of the essential minerals from the leaves for the tree’s growth.
• Oriented Strandboard, also known as particleboard, is a nonveneered wood panel made through bonding small wood particles under heat and pressure.
• Medium-density Fiber Board varies in thickness from 6-40mm and can be used as furniture, paneling, and sidings.
• Parallel Strand Lumber is a type of engineered wood, meaning natural defects like knots, shakes, or pockets are absent.
• Hardboard, also known as compressed fiberboard, is a dense type of fiberboard used for furniture, house siding, wall paneling, and concrete forms.
• Fiberboard is a material made of wood or other plant fibers compressed by a binder into rigid sheets.
• Commercial Size: 4 ft x 8 ft (1220mm x 2440mm)
• Chipboard, also known as particleboard, is a nonveneered wood panel made through bonding small wood particles under heat and pressure.
• The manufactured nature of PSL lessens the chance of the wood from shrinking, warping, cupping, bowing, and twisting.
• Parallel Strand Lumber is a structural wood product made through bonding narrow wood strands together under heat and pressure using a waterproof adhesive.
• Parallel Strand Lumber is used for beams, columns and other structural elements due to its easily predicted strength and durability.
• Sapwood is the younger portion of the tree characterized by its soft texture and lighter appearance in contrast to Heartwood.
• Xylem acts as the trees support that carries water and nutrients from the roots to other parts of the tree.
• Heartwood is the hard-inactive core of the tree defined by its darker tone in contrast to sapwood.
• Pith is the soft core within the heartwood.
• Toleration and reaction to fire may be engineered to prevent it from ignition.
• Lumber can undergo pressured and non-pressured process to treat wood.
• Wood composites can be both designed for structural and non-structural use.
• Thermosetting plastics are rigid and cannot be reformed using heat.
• Lumber can be rough, dressed, or seasoned.
• Lumber degradation is caused by weathering, decay, and insects.
• Plastics has a wide array of use.
• Lumber should undergo seasoning and treatment to protect it from degradation.
• Wood used in construction are classified between hardwood and softwood.
