A replacement window is a window that is installed in an existing window opening. The substitution takes the place of existing windows when they have become impaired, drafty or non-functional. In addition, due to advances in window technology, new replacement windows may greatly decrease energy loss and outside noise compared with older windows installation.
Replacement windows are designed for a variety of situations and installation techniques.
In a full-frame installation, cut around the window you want to replace (interior and / or exterior) is removed and the old window frame is completely removed. The replacement window is secured to the studs around the window opening, and the trim is replaced.
Facilities insertion sometimes used to replace old wood windows with frames that are in good condition. In this case, the replacement window is installed within the existing framework. This installation technique is easier than a full frame installation, but reduces the size of the opening of the window due to a nesting of frames.
Another technique is to replace the window belts only, and reuse the existing framework.
Materials replacement windows are available in various materials like wood, fiberglass, wood-clad aluminum vinyl wood clad, vinyl, glass blocks and other composite materials. The most common materials for new windows are PVC and wood.
Advantages and disadvantages of replacing a window
