What are various windows made of and what will work best for me and/or my customers?
Basically there are three types of materials used. Aluminum windows, with their easily scratched painted surfaces, conduct both heat and cold, so they’re very poor insulators. Wood windows, which require constant painting and caulking, can absorb moisture, making them difficult to open and close. They can even rot. Solid vinyl windows, however, never need painting and won’t show scratches, because the color goes throughout the material. This is why vinyl windows are quickly becoming the most popular choice for both new construction and replacement applications.
