Top 10 Questions to Ask Before Buying Energy-Efficient Windows

Getting new windows is a big move. In addition to beauty, energy efficient windows can save you a lot of money in your utility bills and make your home very comfortable. Here are the top 10 most effective questions you must ask your supplier or installer in order to make an informed choice.

What are the energy efficiency ratings and certifications for these windows?

You should seek formal ratings by known organizations. ENERGY STAR label is one of the primary efficiency indicators in the U.S. NFRC label is also essential because it offers impartial ratings on the energy performance of a product, and by this means; you can easily compare different models on equal terms.

What is the estimated annual energy cost savings with these windows?

Although the amount saved depends on weather and window size, don't worry, suppliers may well give you an estimate depending on the area you live in and the size of your window. This estimate allows you to learn the payoff and the time it may take the windows to pay back with reduced heating and cooling expenses.

Is the window frame made of aluminum alloy, wood or composite material?

Frame material has a great influence on insulation. Aluminum is a good conductor, whereas wood and/or vinyl are more thermostat resistant. Composite materials can sometimes offer a great combination of energy efficiency and durability therefore it is necessary to know the advantages and disadvantages of each.

Whether the thermal insulation bridge or multi-layer glass design is adopted?

Most of the contemporary windows have thermal breaks incorporated in the frame to discourage heat transfer. Likewise, performance is greatly enhanced with double or triple-pane glass with insulating gas fills between the panes such as argon. Affirm these characteristics are a part of the design.

What are the specific U-value and shading coefficient of glass?

Request the particular U-value and Solar Heat Gain Coefficient (SHGC). The U-value is used to determine the level of insulation of the window; the smaller the better. With lower SHGC, the solar heat it blocks is minimized, and in hot climates, the lower the SHGC, the better; higher SHGC in cold climates can be good.

Is there a warranty period and what does the warranty include?

Good warranty covers your investment. Ask what the coverage duration is and more importantly what it covers. Does it include glass seal failure, hardware and frame materials? Can the warranty be transferred with home disposition?

Is it easy to maintain and clean?

Look at the maintenance in the long run. Certain frames need to be regularly painted or stained and others virtually maintenance free. Upgrades, such as tilt-in sash, can easily and safely clean up the outside of your house glass.

Do different styles and colors affect performance?

Although aesthetics matters, inquire whether some colors or finishes have any effect on performance. The dark colored frames may absorb more heat and this may impact efficiency in warm climates. Avoid the style selection weakening the insulating capability of the window.

Do you provide comprehensive installation guidance or professional installation services?

Installation is no less important than the quality of windows. All the positive effects of an energy-efficient product may be eliminated by poor installation. Establish whether the supplier provides professional performance or it is a DIY project; in this case, comprehensive instructions on how the project can be fitted to ensure a perfect, airtight fit.

Does it comply with local energy efficiency standards and policy subsidies?

Lastly, make sure that the windows are in accordance with your local building codes and energy savings. Also, inquire whether they receive any government rebates, tax credits or energy saving programs, and this may be used to subsidize the initial purchase price.

Answering these questions will enable you to make the right decision with the right energy saving windows to your home in order to stay comfortable, save money, and be satisfied with your choice over the years.
