What type of windows are best for my home?

There are a number of different types of window materials that are used in today's markets. Price, quality and features vary with each type of window and manufacturer:

Aluminum frames are what you might have in your home presently. Aluminum frames are not very efficient and have a tendency to sweat with condensation and are being phased out by most manufacturers.
Vinyl frames are far more efficient and more affordable than aluminum frames and seem to be the product of choice for most new construction and replacement applications.
Fiberglass frames are efficient and strong, have the bulkier look of wood, are paintable with very little expansion and contraction. These frame types are more expensive than vinyl frames but less expensive than wood frames. Fiberglass frames are an excellent alternative to vinyl frames.
Wood frames are beautiful, efficient and are the choice of the discriminating homeowner. Wood frames can be expensive and generally have an engineered cladding to the exterior of aluminum, vinyl or fiberglass.
In real estate terms, location, location, location, as well as appearance, will be the deciding factors in choosing which type of window will work best for your home.
