Study Notes

Asbestos Cement Shingle

Primarily composed of cement and asbestos fibers.

Asphalt Felt Siding

Made by saturating dry felt with asphalt.

Balloon Frame Construction

Vertical studs in exterior bearing walls extend the full height from sill to roof.

Battens in Siding

Serve to cover joints between vertical strips of wood.

Bottom Plate

Structural member laid on the subfloor where vertical studs are anchored.

Bridging Function

Prevents movement from vertical axes between parallel-frame members in wooden structures.

Cantilevered Structure

Characterized by an overhang supported from only one end.

Chamfering Purpose

Retards ignition by cutting off corners of timber.

Chipboard Composition

Made from wood chips glued together to form flat sheets.

Corrugated Metal Siding Hazards

Poses an electrical hazard from stray wires or lightning.

Curtain Wall

Type of wall that carries no load other than its own weight.

End Matched Lumber

Features tongues and grooves at the ends for secure fitting.

Engineered Wood Usage

Commonly used as laminated timbers modified from their natural state.

English Tudor Construction

Resembles post and frame but actually uses a balloon frame design.

Finger Joints in Wood Construction

Interlocking wood pieces glued together to create longer dimensional lumber.

Flitch Plate Girder

Composite structure made of a steel plate or plywood sandwiched between two beams.

Glued Laminated Timber (Glulam)

Formed by gluing together planks to create solid timber.

Header in Construction

Used to create an opening by paralleling floor or roof beams.

Heavy Timber Construction

Characterized by large-dimension combustible materials with noncombustible exterior walls.

Ridge Board

Fastens the upper ends of rafters in roof construction.

Joist Definition

A wooden beam that runs parallel to others and supports a floor or ceiling.

Legacy Construction

Utilizes solid wood members instead of lightweight wood trusses and I-joists.

Log Cabin Structure

Constructed using entire tree trunks for walls.

Rough vs. Planed Lumber

Rough lumber has a sawn finish, while planed lumber has a smooth finish.

Sill Purpose

Acts as the base of a wall, resting on and bolted to the foundation.

Soffit Description

A false space above cabinets or under eaves, serving decorative and functional roles.

Sole Plate in Stud Wall

The horizontal framing member at the base of the wall.

Spliced Timber

Timber joined with metal connectors to effectively transfer loads.

Stringers in Stairs

Support the risers and treads, forming the main structural element of stairs.

Stucco Composition

Typically made from Portland cement.

Trimmer in Floor Construction

Supports a header in floor openings, such as stairwells.

Trunnel Usage

Used to pin together mortise and tenon joints.

Truss Frame Definition

A wooden frame that utilizes truss members instead of solid beams.

Truss Void

A space located between the top floor ceiling and the roof in truss systems.

Valley in Roofing

The lower slope formed by the connection of two inclined planes of a roof.

Vermiculite Application

Used as bulk insulation and an aggregate in insulating materials.

Vinyl Siding Fire Hazard

Deforms and drips when exposed to fire, posing safety risks.

Wall-Bearing Building

Load is carried entirely by the walls, providing structural support.

Wood Lath Purpose

Provides a surface for plaster to adhere to in older buildings.

Wooden-Walled Building

A building where load is carried by walls, typically with wooden interiors.
