Windows come in a variety of material types from wood, aluminum, vinyl, and fiberglass. Common choices tend to be wood windows, which offer an extremely classic look to your home. This means that the windows fit with modern homes as well as older houses, and can be purchased to match the existing windows – which makes it easier to upgrade frames a few at a time.
Vinyl and aluminum windows are used in new construction, and are very thin – but still a great choice.
And last, we have vinyl windows. These window types come in a variety of different colors, and require less maintenance (and not painting!) than their wood counter parts. They have a look about them that may not be as classic looking as a wooden frame, but they are a less expensive option without sacrificing quality.
