Top Benefits of Bay Windows

Increasing Energy Savings

Replacing bay windows will undoubtedly increase the energy efficiency of your home. Did you know, however, it may also qualify you for a tax rebate if you use an Energy Star product? The Energy Star program was created to encourage homeowners to use energy efficient materials when doing improvements on a home. Be sure to check with your electric and gas companies to see if they are offering any rebates on energy efficient home improvements as well.

If a product has the Energy Star sticker, it means that it has passed government mandates for energy efficient designs. Using Energy Star products can provide you with excellent tax savings if you save your receipts and purchase them within the qualifying dates of current programs.  Check with your local government  and your electric and gas company tax credits and for energy rebates, respectively. The Energy Star label also ensures you are using the best products for saving on the home's heating and cooling costs. 

Energy Efficiency

A window's energy efficiency is determined by three major factors, the U value, or U factor, the air infiltration, and the solar heat gain. The U value is the measurement of the amount of heat that infiltrates a home through the glass. If the unit has a high U value, it lets in a lot of heat from the sun - this may be desirable depending on which climate you live in. A lower U factor means lets in less heat which is desirable in hotter climate zones.

Window Frame Air Infiltration

The air infiltration is the measurement of the amount of air that leaks around the frame. You can tell when a frame has a high air infiltration rate because you will feel the air coming in, creating a draft in your home. Solar heat gain is the amount of solar energy that comes through the glass. In areas that have warm climates it is desirable to have lower solar heat gains than in areas with colder climates.

Being green is something that is important to many people. Whenever you buy replacement bay windows you should find out what kind of energy efficiency each window that you look at has. Some people will only look for the Energy Star rating, but it is important that you look deeper than that. Looking at the u factor, SHGC, and air infiltration rates of a window will allow you to get a clearer understanding of the overall energy rating for your specific climate. The u factor of a window is a measurement of the rate of heat which is transferred through the window. The lower u-factor number, the better.

Bay Window Warranties

Checking the warranty of your new bay windows is something that you should always do prior to purchase. They can vary widely from manufacturer to manufacturer, and retailer to retailer.  When a company is confident in their product, they are not afraid to offer a long warranty. You should check the warranty on the glass and the non glass parts of the window individually. Usually the glass warranty is going to be longer than the frame parts warranty.

When you are looking at options to replace your bay window, you may think that you want to buy off the shelf. Some people, however, like to customize their arrangement so that they can get exactly what they want. If you see something that is already set up that you like, you can save time and money by going with a standard window size, if your rough opening is the right size for the standard sized window. However, most manufacturers can and will custom make a bay window to fit any size and shape opening.
