Energy Efficiency

If you are primarily concerned with energy savings, you'll want to carefully check out the energy efficiency ratings of any windows you choose. You should specifically be looking for features such as low-e coatings, multiple glazing, gas fills, and frame materials that insulate instead of letting cold air into your home. If energy savings is your primary concern, you are going to find that the prices of energy-efficient windows are somewhat higher than for regular windows. But, you'll need to remember that this initial higher expense will be offset over time with reduced home heating and cooling costs.

Functionality

If the window currently doesn't provide functionality that you desire in a room, you need to consider what features you need before you replace them. For instance, if a current window doesn't open, as is common with picture or bay windows, and you wish them to open, you'll want to look for replacement windows that can combine a large window with perhaps side windows that can be opened. The same is true with single hung or double hung windows, which slide up and down, as opposed to casement windows, which swing open. If you have one style of window, and yet desire another, you'll need to take this into consideration when upgrading your windows.

Maintenance

Maintenance is another important factor to consider when upgrading your windows. Window frames are made of various types of materials, including wood, vinyl and aluminum. Each has their particular advantages and disadvantages. For instances, wood window frames need to be kept painted or stained. Aluminum and vinyl window frames are easy to maintain, but you wouldn't be able to stain them if that was the look you wanted.

Other Considerations

When choosing the material for your windows, there are other factors to consider as well. For instance, if you have a large window with heavy panes of glass, fiberglass windows, because of their strength, would be a good choice. Vinyl is affordable and durable, but might not be a good choice in areas subjected to extreme heat or cold, because they can become distorted. Aluminum windows are lightweight and easy to open, but are often not properly insulated. Wood insulates well, but they are expensive and need more upkeep than other types of windows. Clad windows are often a popular choice, because they provide durability on the outside of the home, and beauty of wood on the interior.
