Updated 6 months ago by Jill Bowers

I

I-joist Wood beams that have top and bottom chords made out of laminated veneer lumber (LVL) or dimensional lumber and the center web made out of either plywood or oriented strand board. I-joists are stronger than joists made out of dimensional lumber and can often span from basement wall to basement wall, although in most cases a center bearing wall is still required.
Ice-damming Condition that occurs when snow melts on the heated portion of an improperly ventilated roof. The water drips down to the unheated portion where it freezes into ice. Eventually the build up of ice will cause the roof to leak.
Identification The third of the six points of estimation, identification is where the estimator decides what an item is. For example, identification occurs when an estimator decides that a wood base is 3 1/2" paint-grade colonial base.
Indoor-outdoor carpet Type of carpet that may be used in interior or exterior applications. Originally, indoor-outdoor carpet was made to imitate grass, but today it imitates many types of traditional interior carpet. See wool carpet, nylon carpet, berber carpet, sculptured carpet, and shag carpet.
Injected insulation Insulation that is injected into place. There are two types of injected insulation. The first is foam that is injected into holes and cracks through tubes. The second is insulation that is injected through mesh into a framing cavity.
Inside corner Corner formed where two walls meet at less than a 180 degree angle.
Inspection wizard The Inspection wizard flags anything in the estimate that does not meet the predefined criteria that has been established for a given Profile. For example, flooring added to a room that exceeds the total square footage of the room is flagged as a violation, since this would fall under the Xactware rule of Excess. Depending on the Profile's Preferences settings, the inspection is Run on Complete and/or Run on Print. The inspection can also be run at any time within the estimate.
Insulated flue Flue consisting of an inner pipe and an outer pipe with the space between the two filled with heat-resistant insulation.
Insulation board Board used as a barrier against thermal or sound transmission. Insulation board may be made from fiber, pressed wood, or foam.
Insulation stop Material placed in the roof system to prevent insulation from falling through the space between the top of the exterior wall and the bottom of the roof sheathing.
Insurance carried/required Insurance Carried/Required is a ratio of insurance coverage to the value of the property insured. This field on the Loss Recap report, defaults to 1, which is correct unless the property is under-insured. This factor is calculated by dividing the insurance carried by the insurance required. For example, if an insurance policy requires 80% insurance to value (coinsurance) and, if a building were currently valued at $100,000, the Insurance Required for that building would be 80% of $100,000 or $80,000. If the Insurance Carried for the same building were only $60,000, you would calculate the Insurance Carried/Required ratio as follows: Insurance Carried ($60,000) ÷ Insurance Required ($80,000) = .75.
Integral drawer Type of drawer in which the face serves as the front piece of the drawer. The drawer sides attach directly to the drawer face. See attached drawer.
Interior plaster Plaster that is used as a wall or ceiling finish inside the structure.

The isolation membrane protects tile from movement in the underlying systems absorbs water that penetrates the tile surface. A mortar bed and cement board are two types of isolation membranes. See thinset tile, mortar bed, and cement board.
ITEL ITEL is an independent third party that provides unbiased analysis of damaged materials. A sample of the flooring and/or siding is sent with an ITEL Request Form. After the sample is received, ITEL performs a detailed analysis to determine the pertinent material specifications so that an appropriate match can be found. This feature requires a customized profile.

Organization The second of the six points of estimation, organization is the method used to document the loss. Organization often begins with an accurate and detailed interior and exterior areas. The interior is organized by levels, such as the basement, main floor, and attic. Each level is then broken down into rooms. The estimate should usually start in the room and level where the damage point of origin is found. Other rooms are estimated in a clockwise (or counter-clockwise) direction from the first room. Center rooms and halls are estimated last. When all rooms in a level are complete the estimator moves to the next level and repeats the procedure, usually starting in the most heavily damaged room.
Oriented strand board (osb) Type of wood product used for sheathing, it is produced by gluing together three layers of wood chips or strands that are smaller than the chips used in waferboard and are longer than they are wide.

For example, if your estimate contains a custom-made item for which you have not yet received a bid, you can add the price note "Bid Pending."
Price list A price list contains commonly used items and their associated costs, from which an estimator can select when creating an estimate. In Xactimate, you can create and store as many price lists as they want in order to cover different jobs and geographical areas. Xactware researches and publishes separate, localized price lists for nearly 500 individual markets in North America, with costs based on local and regional material, labor, equipment, and unit cost information, as surveyed from suppliers who service each individual market. Published price lists can be used and edited to fit a company's needs. During the estimating process in Xactimate, users can use a published price list cost for items, or can choose to enter line item costs for individual tasks, summarized costs for each phase of the job, or the total job price as miscellaneous items.
Price List Audit Report On the Price List Audit Report you can compare a modified price list with it's original. A modified price list is a price list that has been changed, duplicated, or created via Compare/Merge.
Price List Editor The Price List Editor allows you to view, edit, duplicate and delete items in non-read-only price lists.
Price List Filter The Price List Filter Editor lets you create and/or edit a price list filter, which you can then use to filter out price list items that you don't want to see when scoping your estimate(s).
Price List Merge Wizard With the Compare/Merge Price List Wizard you can evaluate the differences between two price lists as you combine (merge) them. This would be helpful, for example, if you have customized some aspects of a price list according to your specific needs and then receive a new version of that list with updated pricing data. In the information windows you can modify the Source price of a selected component prior to merging it into the Target price list in the Compare/Merge Price Lists Wizard.
Price List Supporting Events The Price List Editor Supporting Events menu displays indirect activities (such as waste) that are used by price list items, along with a list of all items that use the selected supporting event. For instance, the supporting event FCRLINO (linoleum floor waste due to handling, cutting and fitting) is used in both price list item FCRLINO (Linoleum floor covering sheet goods) and FCRRUB (Rubberized floor surface—glued sheets, poured or rolled).
Pricing Numerical amount(s) individually and holistically of line items, materials, equipment and labor of a given project(s).
Primer First coat of paint applied to a surface in order to seal the surface and provide a good base to which the paint may adhere.
Privacy hardware Interior door hardware which locks. See passage hardware.
Profile manager With the release of Multiple License Versions by Xactware, certain carriers approve specific versions of Xactimate for use with their profiles. The Profile Version Manager allows you to view the version to which each profile is set.
Project Filter In the Project Filter/Search window you can temporarily filter out projects from the Projects List. This is helpful if you have a large number of active projects and need to find specific kinds of projects. For example, you can create a filter that displays only estimates that you personally created, temporarily removing the projects created by other Xactimate users.
Project Merge Wizard With the Project Merge Wizard you can create several, separate estimates for a single claim and then merge them into a one estimate prior to completing the claim. This is helpful when you want to assign several different adjusters to work on a claim that has many similar rooms, such as an apartment, flat or condo complex.
Project Preview pane The Project Preview pane appears by default in the upper right corner of the Control Center Dashboard window. It displays the lowest level of the sketch for the estimate highlighted in the Recent Projects List. The arrows at the bottom of the Project Preview pane allow you to view other levels of the sketch.
Project SmartList The Projects SmartList displays all current projects, regardless of status, type, profile, or user ID. The Projects SmartList allows you to quickly open existing projects, edit projects, create new projects, and view estimates or valuations. In the Project Information window you can view information about a project, rename or reassign a project, and modify and print notes.
Protected pattern A pattern left on a surface that was exposed to heat and smoke. Items on the surface, such as appliances and dishes, protect the areas they rest on from heat and smoke. When the surface is cleaned a pattern remains because the exposed areas discolor more than do the areas that were covered.

Pythagorean theorem A mathematic relationship between sides of right triangles specifying that the length of the hypotenuse (longest side) squared equals the sum of the lengths of the other two sides squared. It is often expressed as: "a squared + b squared = c squared. " The theorem can be used to solve for any side of a right triangle where the lengths of the other two sides are known. To solve for side "a," use the formula "a = c - b." To solve for side "b," use the formula "b = c - a."
