About New Windows

Cost

• Cost is a big factor when selecting windows for a home. Setting a budget should be the first step for any home remodeling, and that budget should also apply to window cost. It is important to research manufacturers to find out what costs will include -- warranty information and replacement policy are of utmost importance. It is also important to understand their policy on installation and a quality guarantee. As of 2009, average window costs range between $300 and $700 per window, according to MBM Carpentry. This cost will increase drastically if the home has structural damage. In that case, these costs may double.

Design

• Knowing the types of windows and the benefits of each will aid in making the best window selection. When seeking a window that is energy-efficient, it is important to become familiar with performance ratings and how they vary depending on the region. Frames, which are an important part of energy efficiency, are available in a number of materials, each of which will have their own positives and negatives. Generally, wood, vinyl and fiberglass are the most desirable. These materials are among the best at regulating temperatures, while aluminum and other metals are among the worst. Glass and glazing options are another important consideration for window selection. To develop the most efficient setup, window options may vary depending on orientation and regional climate. Gas fills, modern insulation and a number of coatings will help make windows as efficient as possible.

Styles

• There is a large selection of window styles available, and selecting the right one will provide both functional and aesthetic benefits. Single- or double-hung varieties are among the most popular. A double-hung window has both top and bottom pieces that open vertically, while a single-hung window features just a bottom sash that opens. Though popular, these style windows tend to have more air leaks than a hinged model. Awning and casement models are hinged and are more energy-efficient than single- or double-hung designs. Fixed windows don’t open at all, and are rarely used in homes. They prevent any airflow from entering the room. Hopper styles are another hinged design that opens inward.

Energy Performance Ratings

• Energy performance ratings will indicate a window’s potential for heat loss and sunlight transmission. These are two important factors in deciding upon a window type and style. U-factor will indicate the rate at which energy will be lost. In doors and skylights, the U-factor will indicate just the glass, while the whole window -- including the frame -- will be rated. Air leakage that occurs around the window is measured, while visible transmittance measures the amount of sunlight that passes through the glass.
