New windows or the retrofit windows (the window replacement option) may be installed
into the homes to enhance their look and to prevent air leak, which is the major concern for making the place thermally incompatible. Replacement windows are less expensive as these are placed on the top of existing frames and do not deteriorate the sidings of the wall. Further, use of vinyl windows ensure proper security of the house, as it comes with an unbreakable glass and other burglar proof features. They contain low-e coating to prevent harmful ultra violet rays and are easy to clean & maintain. Moreover, vinyl windows improve the look of the place and increase the resale value of the house.
