Casement open left
A casement hinged on the left side to open left from the exterior view. [top]
Casement open right
A casement hinged on the right side to open right from the exterior view. [top]
Casing
Molding of various widths, thicknesses and shapes applied to the framework of window and door units. [top]
Caulk
Sealants used to seal fixed and moveable construction joints and prevent infiltration. [top]
Caulking
See Caulk [top]
Cellular PVC
Extruded polyvinyl chloride material used in window and door components and trim. Unlike rigid (or hallow) vinyl, it features a foam or cell-structure inside. It can be nailed, sawn, and fabricated like wood. [top]
Cellulosic Composite
Generally a material combining an organic material, such as wood fibre, extruded with plastic. [top]
Certification
A process that indicates a representative sample of a product line has been tested, that the product meets specified requirements, and that the product is subject to ongoing inspections by an outside certification agency. [top]
Change Directive
A change directive is an instruction to proceed issued by the Contractor. It must commence concurrently with estimating. The change to the scope of work may influence the contract price, and the contract time frame; however, those details are negotiated during or after the completion of the scope of work by the Sub-Contractor [top]
Change Order
A change order is a certification from the Contractor declaring that they accept the terms and conditions of the appropriated change. Conditions may range from a change in the contract price, to a change in the contract time frame. Change orders are used to request a change that is outside the contracted scope of work, or an extra to contract. [top]
Circle-head
See Arched Top. [top]
Circle-top
See Arched Top. [top]
Clerestory Window
A venting or fixed window above other windows or doors on an upper outside wall of a room. [top]
Climb Deterrent
An extruded material installed on the sill extrusion of a window frame intended to prevent anyone from climbing the window. [top]
Combination Door
A screen or storm door used in combination with a primary door. Storm windows also are referred to as combination windows. [top]
Compatibility
Compatibility is the ability of two or more materials to exist in a close and permanent proximity for an indefinite period of time with no adverse effects on each other. [top]
Compensation Channel
Compensation channel is the sleeve that is installed on the rough opening jamb of every seismic installation to provide the project with compensation on either side of the frame for seismic drift. (Also Seismic Jamb) [top]
Composite
A term used for window or door components which consist of two or more materials, such as wood and plastic. The term also is used for windows and doors which combine two or more materials in the frame or sash construction such as a product with wood interior and a vinyl or aluminium exterior. [top]
Concrete Slab
See Slab. [top]
Condensation
Condensation is caused by water vapour from the air being deposited on any cold surface (which has a temperature below the dew point) when warm air meets the cold surface. Warm air has a greater ability to retain moisture, as the air cools it loses its ability to retain the moisture and condensation is formed on the cold surface. [top]
Construction Manager
See Contractor. [top]
Contemplated Change Order
A contemplated change order is a request from the contractor declaring that they are thinking of issuing a change to the contract or scope of work, and that they want input from the Sub-Contractor such as an estimated cost, or time frame before issuing a change order. [top]
Contractor/General Contractor/
The commercial entity or person contracted by the owner of the construction project to oversee the construction of the building; the contractor is responsible for hiring and monitoring the sub-contractors (construction sub-trades such as electrician, dry wall installation or window installation etc.) [top]
Cope
To notch aluminium framing members such as a jamb profile or corner post, so that another member may be fitted flush against it, or so it can bypass the concrete curb in a bypass or parapet frame. [top]
Coped Joint
A term used to describe a joint between two framing members where one extrusion is cut to the profile of the second. [top]
Corner Cap
A corner for sill flashing or bypass flashing that is pre-fabricated in the Shop before shipping and installed over existing runs of sill flashing or bypass flashing at its corresponding corner. Sometimes joined with rivets, or held in place with caulking before the corner post is installed. [top]
Corner Post
An extruded aluminium coupler designed to hold two frames together at a desired angle, Corner posts utilizing more than one extruded profile are called variable corner couplers. [top]
Countersink
To form a depression to fit the conic head of a screw or the thickness of a plate so that the face will be level and flush with the surface. [top]
Coupler
Couplers are used to join two window or door frames, together. They typically come in 45°, 90°, or 180° couplers; however, variable coupler corners can be utilized to make a variety of others. [top]
Crazing
Minute cracks in a surface or coating caused by force bending a material beyond the recommended radius. [top]
CRF
Condensation Resistance Factor.
A rating of a window's ability to resist condensation. The higher the CRF, the less likely condensation will occur. [top]
Curing
Curing is the process of allowing sealants to dry and harden over a given period of time. [top]
Curtain Wall
An exterior building wall which carries no roof or floor loads and consists of a combination of aluminium, glass, and other surfacing materials supported solely by the aluminium framework. [top]
