Deck Speak: Terms to Know
Decks and patios come in a wide range of designs, shapes and sizes. While the look of a deck may differ from one to another, the make-up of most decks remains the same.
Decks are composed of a variety of parts. Structural parts of the deck hold and distribute the weight of the deck and therefore, should be made of durable, high quality materials. Posts, ledgers, beams and joists should be made of pressure-treated wood for longer life and maximum durability, often required by code. However, visible parts of a deck including the decking, railings, stairways and facing can be made of cedar, redwood or composite for a more attactive touch.
Baluster: One of a series of vertical supports used between posts of a railing. Also called a spindle.
Cap Rail: The top horizontal piece of a railing, usually placed to give it a finished appearance.
Composite Decking: Deck boards manufactured from wood fiber and plastic to form a profile which requires less maintenance and generally has a longer lifespan than natural wood.
Fascia: The boards used to cover rim joists and end joists. Also called "skirt".
Fasteners: Generic term for nails, bolts, screws and other connecting devices.
Footing: The below-ground support of a deck's post, usually made from concrete.
Joist Hanger: A pre-manufactured metal piece typically attached to a ledger or beam to support a joist. Joist hangers should be galvanized.
Joists: Horizontal framing members that support decking; a system of sub-deck structural elements located directly beneath the deck boards, commonly using 2 x 6 or 2 x 8 lumber.
Ledger: A length of board, that is horizontally attached to the side of a house and holds up one edge of a deck.
Post: The vertical structural element that rests on the footing and supports the beam.
Post Cap: A small piece of material (often wood) attached to the top of the post to cover the post's wood grain and protect the post from the weather. Can be made of many materials including metal, Injection-molded plastics, even decorative glass tops for round and square posts.
Pressure Treated Wood: Wood subjected to a high pressure treatment of chemicals as a preservative.
Riser: The vertical piece between two stair steps.
