Replacement Windows Basics, What You Need To Know
The addition of a storm window to a single-pane window can often outperform some replacement units. The majority of newer replacement windows carry the "Energy Star" rating for home efficiency, and may be custom ordered to meet the customers preferences, both functionally, and aesthetically. While most replacement windows are used in residential applications, there are numerous commercial applications as well, such as storefronts, offices, and workshops.
Replacement vs. New-Construction Windows
Replacement windows should be distinguished from new-construction windows. New-construction windows have a "fin" along the outer frame. This fin provides a surface so that the window can be nailed in from the outside of the home before the application of siding. Unfortunately, new-construction windows may be of inferior quality as builders continually try to keep costs low. Replacement windows have no such "fin". This allows them to be installed with minimal disruption to the existing trim/siding. They are set into place in the existing window frame and nails or screws are driven into the window from the inside of the window jamb.
Installation may be done from the inside by the removal of the inside trim, or from the outside by the removal of the outside "stops". Outside installation requires either replacing old stops with new ones, or a custom metal wrap, but can be useful if the inside trim is too precious to be disturbed. All windows should be sealed inside and out with a high quality silicone caulk. While replacing your home windows can be a do it yourself project, it is most often best accomplished by a window replacement contractor.
Replacement Window Materials
Replacement windows are available in several materials including wood, fiberglass, aluminum-clad wood, vinyl-clad wood, vinyl, or recently, a composite of wood and plastic. Vinyl replacement windows are a very popular choice as they are the least expensive and now comes in many pre-molded colors. This also appeals to those seeking a low-maintenance lifestyle, such as condominium owners, senior citizens and lower- or fixed income families.
Most installations are completed with a custom metal "wrap", which acts as an added barrier against the elements. PVC-coated aluminum comes in a myriad of colors and requires no painting. Solid vinyl exterior trim is also an option.
Replacement window screens can be full-sized, half-sized or retractable. A variety of materials, from aluminum to durable vinyl/fiberglass "pet-screens", are available.
