PVC Windows Glossary Two:
PVC Picture Window: A fixed window typically of a large size in relation to adjacent windows.
PVC Picture Window: A large stationary window used to capture wide views of exterior landscape. Can be combined with other functional windows such as a double-hung or casements, and/or topped with direct-set or awning pvc windows for enhanced views.
Rails: The horizontal members of the framework of a PVC window sash or door panel.
Rough Opening: The opening in the wall where the pvc windows or doors is to be installed, slightly larger than the size of the unit to allow squaring.
Round Top (Circle Top): Direct set quarter circles, half circles, half ellipses, arch tops, ellipses, full circles and gothic arch top windows that can be used alone, in combination or stacked above another pvc window or door.
R-Value: A measurement of how much a material resists heat transfer. A higher R-Value means a greater insulating effect and a lower rate of heat flow.
Safety Glass:See tempered Glass
Sash: The top and bottom horizontal rails and vertical left and right stiles that house the PVC window glass.
Side Jamb: The vertical left and right members of a frame.
Sidelite: A narrow fixed or operating sash consisting of either steel or wood stiles and rails, glazed with clear or decorative glass and matching the sight lines of the entry door. Sidelites are typically mulled to the entry door on one or both sides.
Sill: The bottom of the frame of pvc windows or doors.
Simulated Divided Lite: PVC Windows with grilles adhered to the interior and exterior of the window glass, in a variety of decorative options, to simulate the look of True Divided Lite.
PVC Sliding Patio Door: Up to four glass door panels that slide on tracks giving fast, easy access to the outdoors.
PVC Slider Windows: A window with a sash or sashes that move horizontally.
Solar Heat Gain: Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted and absorbed, then subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a PVC window's SHGC, the less solar heat it transmits.
Spacer: An anodized aluminum bar used to separate the panes of glass in an insulating PVC window.
Tempered Glass: Float glass that is heated and then cooled rapidly to make it several times stronger than annealed glass. Standard in all Weather Shield doors, tempered glass is safer than annealed glass because when it is broken it falls into pebble-0like pieces without sharp edges.
Tilt: Both sash of this PVC windows slide up and down to allow air into the room, as well as tilt into a room for easy cleaning on both sides.
Transom: A PVC window stacked above another window or door.
U-Value: A measurement of how much energy a material conducts. The lower the U-Value for PVC windows, the greater the insulating effect.
Visible Transmittancel: Visible Transmittance (VT) measures how much light comes through a product. The visible transmittance is an optical property that indicates the amount of visible light transmitted. VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted.
Weatherability: Performance in various climates.
Weather Stripping: A strip of resilient material designed to seal the PVC windows sash and frame members to reduce air and water infiltration. |
