Air Barrier Paper/Air Vapor Barrier <ul><li>A sheet material used as both a vapor retarder and an air barrier. When carefully taped at joints and sealed at edges, it is very effective. </li></ul>
Attic Ventilation <ul><li>Attics are ventilated not only to allow water vapor to escape, but also to keep the house cooler summer by preventing the buildup of solar heat. </li></ul>
Soffit Vent <ul><li>An opening under the eave of a roof, used to allow air to flow into the attic or the space below the roof sheathing. </li></ul>
Ridge Vent <ul><li>A long, open assembly that allows air to circulate in and out of a gable roof at the ridge. </li></ul>
Gable Vent <ul><li>A screened , louvered opening in a gable, used for exhausting excess heat and humidity from an attic. </li></ul>
Roof Turbine <ul><li>A turbine vent is a passive ventilation device that exhausts humid, hot air from an attic. Some forms of turbines are equipped with an electric motor (pictured above). </li></ul>
Backhoe (24”) <ul><li>Piece of excavating equipment consisting of a digging bucket on the end of an hydraulic arm. Typically mounted on the rear of a front-end loader. </li></ul>
Batter Boards <ul><li>A temporary frame built just outside the corner of an excavation to carry marks that lie on the surface planes of the foundation that will be built within the site. </li></ul>
Brick Arch <ul><li>A structural device that supports a vertical load by translating it into axial, inclined forces at its supports </li></ul>Segmental Arch Gothic Arch
Brick Bonds (Running Bond & Stack Bond) <ul><li>Running Bond – Bricks that have been laid in alternating positions consisting entirely of stretchers. </li></ul><ul><li>Stack Bond – Bricks that have been laid stacked directly on top of the previous course. </li></ul>Running Bond Stack Bond
Stone Cladding & Wood Cladding <ul><li>A material used as the exterior wall covering of a building. This pattern in this stone cladding is coursed ashlar. </li></ul>
Wood Shingle Cladding <ul><li>Wood Shakes – Shingles that have been split from a block of wood. </li></ul><ul><li>Wood Shingles – Shingles that have been cut and having a uniform thickness. </li></ul><ul><li>Pictured above are Wood Shingles. </li></ul>
Code Requirements: Egress from Window <ul><li>The IBC for emergency exit and rescue from a window requires that the net window area when open be equal to 5.7’. The window pictured above has net open area of 5.625’, and therefore does not meet the IBC. </li></ul>
Code Requirements (Residential Stairs) The stairs shown to the right were measured with a tread depth of 11” while the risers were at a height of 7 ½”. The IBC states that for residential stairs the treads shall measure a minimum of 10” and the risers shall measure a maximum of 7 ¾”. These stairs DO meet the IBC.
Concrete Joints <ul><li>An intentional linear discontinuity found in large concrete slabs and often sidewalks, for the purpose of controlled cracking in the material to minimize or eliminate cracking elsewhere. </li></ul>
Isolation Joint <ul><li>Isolation joints are used to help relieve stress, in this case of the precast column adjacent the slab-on-grade. Here the column is being isolated from the slab. </li></ul>Precast Concrete Column Slab-On-Grade Isolation Joint
Concrete Masonry Unit (CMU) <ul><li>A block of hardened concrete, with or without hollow cores, designed to be laid in the same manner as a brick or stone. The most common block is nominally 8”x8”x16”. </li></ul>
Decorative CMU Ribbed Concrete Blocks Split – Face Block
#3 Floor Joist <ul><li>This home was constructed with a slab-on-grade foundation, therefore no floor joists were required. However, these pre-fabricated “bar joists” serve as the floor joists for the second story floor. </li></ul>
Lintel <ul><li>A beam that carries the load across the opening of a window or doorway. </li></ul>Lintel
Mortar Mortar Joint #1 – Joint #1 appears to be a troweled joint, the measured width was 3/8” the type of mortar is most likely N. The above bldg can be considered a commercial use structure. Mortar Joint #2 – Joint #2 appears to be a tooled joint, the measured width of the joint was 3/8”. The mortar type is most likely N. The above bldg can be considered a commercial use structure.
Oriented Strand Board (OSB) <ul><li>OSB is an engineering, non-veneer panel wood product produced by layering stands of wood in specific orientations. </li></ul>
Plumbing: Lavatory & Water Closet <ul><li>Lavatory requires a 1 ½” drain line. </li></ul><ul><li>Water Closet requires a 3” drain line. </li></ul>Lavatory Water Closet
Plumbing: Shower/Tub, VTR, & Bathroom Sink <ul><li>VTR- Vent Through Roof, allows the escape of gas from plumbing systems. </li></ul><ul><li>Bathroom Sink is a “Drop-In” sink. </li></ul>
Plywood <ul><li>An engineered wood panel composed of an odd number of layers of wood veneer bonded together under pressure. </li></ul><ul><li>Veneer – A thin layer, sheet or facing. </li></ul>
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 <ul><li>The above rebar was measured at 3/8” diameter or # 3 rebar. The purpose of the deformations of the rebar are to give added ability of the concrete to bond with the rebar. </li></ul>
Steep Roof Drainage Gutter Splash block Downspout Downspout – A vertical pipe for conducting water from a roof to a lower lever. Gutter – A channel that collects rainwater and snowmelt at the eave of a roof. Splash block – A small precast block of concrete or plastic used to divert water at the bottom of a downspout.
Steep Roof Materials Underlayment – A layer of waterproof material such as a building felt between roof sheathing and roofing. Shingle – A thin unit of water-resistant material nailed in overlapping fashion with many other units to render a sloping roof watertight. Wood Shingles
Steep Roof Shapes From left top clockwise: Gable Roof Gambrel Roof Hip Roof
Steep Roof Terms Ridge – intersection of two roof planes Valley – trough formed by intersection of two roof slopes. Eave – Horizontal edge at the low side of a sloping roof.
Steep Roof Terms Rake – sloping edge of a steep roof. Soffit – Undersurface of a stair or roof overhang. Fascia – The exposed vertical face of an eave.
