What are Replacement Windows (Retro Fit Windows)?
A replacement window, commonly known as a retrofit window, is a new window installed to replace an existing window. The window may be replaced to improve energy efficiency, appearance or design. Regardless of the method, custom sized windows are installed in the existing frame or rough opening. There are two main methods in which replacement windows will be installed:
1 Removal of old wood double hung sash and replacing with new vinyl, wood, fiberglass or aluminum windows leaving the original wood frame in place. The process does not necessitate the removal or replacement of any siding, exterior or interior trim and is very economical. All windows are custom sized to the existing opening and the new window carries the full warranty offered by the manufacturer.
2 Complete removal of old wood, aluminum or steel windows (including sash and frames) and replacing with new vinyl, fiberglass, wood or aluminum windows. The process includes the removal of the glass, sash and frame and may include alterations to the siding and the replacement of exterior and interior trim. This process is more involved and requires more time but produces a “like new” result for your home or business.
What is a Window?
A manufactured configuration of glass, sash and frame which affords light and / or ventilation in a dwelling or other structure.
What is a Sash?
The term “sash,” in general, refers to the movable panel portion of a window and includes the glass and frame material (wood, aluminum, steel or other). For example, the movable portions of wood double hung windows are referred to as sash. While sash are generally movable, “fixed sash” also exist; the idea being to give a consistent appearance between movable and fixed windows in the same structure.
What is Meant by the Term “Replacement Glass?”
Replacement glass refers to the removal and replacement of old single pane or insulated units with new single pane or insulated units. Work is limited to replacing the glass only, no work is performed on siding, sills or trim.
What is an Insulated Unit (Double pane)?
An “insulated unit” refers to two or more pieces of glass separated by a spacer bar of metal or other material. The two panes of glass are affixed to the spacer bar with some sort of flexible yet strong adhesive causing a seal between the spacer bar and the glass. A desiccant (moisture absorbing material) is placed in the spacer bar and absorbs any moisture trapped during fabrication. The process creates a “dead” air space between the single panes and the resulting insulated unit provides superior thermal performance compared to single pane glass. The space between the single panes may contain air, argon or other inert gases that provide improved performance over air. Insulated units may also be fabricated using coated glass to achieve greater thermal performance, reduce glare or reduce light in the living space.
What is a Failed Unit?
“Failed Unit” refers to the infiltration of air and moisture into an insulated unit caused by the failure of the adhesive seal between the spacer bar and the glass or glass breakage. The resulting failure allows air into the unit, when the desiccant is saturated with moisture, condensation or discoloring appears on the inner sides or the pane(s) of glass.
What is Tempered Glass?
Glass that has been heated to high temperatures in an oven after fabrication is referred to as tempered. Tempered glass is about four times stronger than regular glass. Tempered glass is required by building code in some locations, recommended in large, partially shaded windows and is often required by manufacturers in large windows. Glass must be cut to size and / or shape prior to tempering; tempered glass can not be cut, ground or modified in any way after tempering.
What is Low E glazing?
Low E, or low emissivity glazing refers to the chemical and metallic coating deposited on a pane of glass to improve thermal efficiency. The pane is used in the construction of insulated units.
