Air Barrier paper : material that is impermeable to air flow and is continuous around the whole building
Attic ventilation : During the summer, excess heat that builds up in the attic during the day results in high energy costs for cooling. Also, moisture produced within the home may move into the attic if ceiling vapor barriers are not used. If this moisture is not exhausted from the attic it can condense and cause insulation and construction materials to deteriorate. Soffit vent
Bulldozer : a crawler (caterpillar tracked tractor), equipped with a substantial metal plate (known as a blade) used to push large quantities of soil, sand, rubble, etc., during construction work and typically equipped at the rear with a claw-like device (known as ripper) to loosen densely-compacted materials.
Code Requirements Stairs exceeded 7 ¾” riser and 11” tread by having an 8” riser and 11 ½” tread
Concrete joints Control Joint <ul><li>An intentional, linear discontinuity in a structure or component, designed to form a plane of weakness where cracking can occur in response to various forces so as to minimize or eliminate cracking elsewhere in the structure. </li></ul>
Concrete Joints Isolation Joints <ul><li>A joint, such as an expansion joint, between two adjacent structures which are not in physical contact. </li></ul>
Concrete masonry unit (CMU)- a block of hardened concrete, with or without hollow cores, designed to be laid in the same manner as a brick or stone; a concrete block. Typical dimensions of CMUs are 8” wide and 16” long the two to the right are 10”x8”x16” and 4”x8”x16”.
Front End Loader: is a type of tractor, usually wheeled, sometimes on tracks, that has a front mounted square wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground.
Gypsum Board: an interior facing panel consisting of a gypsum core sandwiched between paper faces; called drywall, plasterboard.
Heat Pump Compressor/Condenser: this increases the pressure of the refrigerant so that it will accept the maximum amount of heat from the air; it contains oils that move heat to or from the air inside the home.
Heat pump <ul><li>Air Handler: fan that blows the air into the ducts of the home. </li></ul><ul><li>Pros and Cons of Heat Pump: </li></ul><ul><li>Advantage: these are one of the most efficient systems you can buy to heat your home. </li></ul><ul><li>Disadvantage: it does not operate well in climates that are constantly below freezing. </li></ul>
Insulation: Batt/Blanket : made up of fiber glass material that is most commonly found in wall cavities
Insulation Loose Fill : thermal insulating material installed in a particular form so as to pour and fill space easily in such locations as cores of hollow masonry units or spaces between the ceiling joists
Insulation Spray Foamed: a plastic thermal insulating material that is sprayed, injected, or poured into a building cavity as a liquid that expands to become a lightweight foam.
Insulation Rigid Board: is commonly used where a high R-value per unit thickness is required or where insulation is used to support another material.
Lintel (Steel) lintel: a beam that carries the load of a wall across a window or door opening.
Mortar Joints Concave: tooled joint; 3/8” thick; type S mortar.
Extruded: 3/8” thick; residential building; type N mortar
Oriented Strand Board (OSB): A building panel composed of long shreds of wood fiber oriented in specific directions and bonded together into three to five layers under pressure.
Plumbing: <ul><li>Lavatory </li></ul><ul><li>uses a 1½” waste pipe </li></ul>
Plywood: A wood panel composed of an odd number of layers of wood veneer (a thin layer, sheet, or facing) glued and bonded together under pressure.
Radiant Barrier <ul><li>A reflective foil placed adjacent to an airspace in roof or wall assemblies as a deterrent to the passage of infrared energy. </li></ul>
Rebar: This particular rebar is ½” in diameter and is referred to as #4 bar. The deformations allow for better bonding to concrete.
Steep Roof Drainage <ul><li>Gutter </li></ul><ul><li>a channel that collects rainwater and snowmelt at the eave of a roof . </li></ul>
Downspout <ul><li>a vertical pipe for conducting water from a roof to a lower level. </li></ul>
Splash block: a small precast block of concrete or plastic used to divert water from the roof above.
Steep Roof Materials Underlayment: a layer of waterproof material such as building felt between roof sheathing and roofing. This layer serves to protect the building from precipitation before the roofing is applied; it also provides a permanent second layer of defense to back up the roofing.
Non Asphalt shingle roof. Shingles: small, lightweight units applied in overlapping layers with staggered vertical joints. This is an example of a metal shingled roof.
Metal Panel Roof: the most common types are fastened to the roof with exposed screws sealed with neoprene washers. Narrower panels approximately 12 inches wide are produced with raised edge seams that include a means of concealed attachment to the roof deck and a snap-together interlocking mechanism.
