According to the U.S. Department of Energy, 20-25% of a home's heating bill is because of the heat loss through the windows. So if your windows are also raising the bills, then you need to think about replacing the window.
How to Choose the Right Replacement Window
To get a better understanding of a window, firstly, understand the difference between a newly constructed window and a replacement window. A newly constructed window will be at a totally fresh place and its design, size and shape, all will be as per the requirement and willingness of the house owner. Newly constructed windows are also called rough opening.
Replacement windows have many restrictions. You have to fix them in the same frame size and have to look for a window that suits your house. To get the best replacement window, you need to understand what you exactly want from a window. Well, here are some of the guidelines and factors which you need to consider while selecting a perfect replacement window.
U factor is the measure for transfer of energy or energy loss. The U factor values usually falls between 0.20 to 1.20, out of which you have to look for a window which has the lowest value or lowest energy loss.
The R factor is a measure for better-insulation or the ability to contain energy. The value of R should be high. The greater the value of R, the more heat resistance and insulated the material will be. So we can say the lowest U factor and highest R factor window can be considered the best amongst all.
You need to decide about the replacement window material. Usually, people go for the same material which has been used previously as the frame will be the same. But you can try out other combination which fit into your budget and can fulfill all your requirements.
Visible transmittance is the amount of light which enters through the window. This may be given to you in the measure of 0 to 1. So, according to the visibility and transmission of light decide the values. It is advisable to go for higher values.
You should go for a company which is ready to stand by their products in terms of warranty and guarantee. No one will like to replace their windows if they just had it changed the previous year. Hence, look for a good company's product. Many companies even offer 10 years warranty.
The cost of the window will depend upon the material, size and design of the windows. The ones which are made out of wood and aluminum are considered to be more expensive than vinyl and wood. Apart from this, if you go for designs and colors or paints on the windows then it may cost you more.
So, these were some of the guidelines for selecting replacement windows. You can also call a professional for installation.
