Tips for Purchasing Energy-Efficient Windows

Purchasing replacement windows will put money back into your pocket if you choose to replace your old existing windows with new energy-efficient windows. You will especially notice a difference during the hot summer months and cold winter months.

It's important to remember your current location and the design and layout of your home. This plays a major role on the style and selection of energy-efficient windows you select for your home.

A family living in the northern region will need different windows than a family living in the southern region. The environment and climate conditions are entirely different, and windows will need to serve each purpose.
The windows you select should be purchased by the design of your home. The direction and size of the windows are more important than one would think.

In hot or heat dominated regions, windows facing south should be heavily glazed. This is done to make efficient use of solar heat during the cold and bitter winter months. The windows should also possess a solar heat gain co-efficient of more than .6 but a U-factor of less than .35 to assure heat transfer is reduced during the hot and humid summer months.

Those who live in cooling dominated regions should focus on the north-facing windows. It is a good idea to have the windows facing the south shaded by trees, bushes and porches to minimize the sunlight and heat. Tinted or reflective windows are not suggested for these climates. It has been suggested they reduce the SHGC and allow more heat in during the spring and summer months.
In the regions where temperature fluctuates higher, wooden frames should be avoided. This has been suggested because the materials have been known to expand and contract. Wood laminate window frames are a better option and maintain the same aesthetic appeal.

If you live in heat-dominated regions, glass-filled windows are the best choice. They provide better insulation and considerably reduce the U-factor. Tinted glass is popular and a good choice. The only downside to tinted glass is it can cause indoor plants to die due to the lack of sunlight.

Glaze glass is another good choice. They have multiple panes of glass. Such types of glass are recommended for cooler climate regions. However, the cost of double-pane or triple-pane windows is much higher than single-pain windows, but they last indefinitely and dramatically reduce cooling costs in the hot summer months.

Before making any quick decisions you should consider the variety of glass before buying energy efficient windows. This is what will determine the amount of energy you conserve. Whatever your choice may be, remember to always take into consideration the available options and select one that best fits your needs.
