Energy Efficient Windows

How to increase the energy efficiency of your windows

July 6, 2015

The windows of your home serve an aesthetic purpose as well as a practical one. Not only do windows give your home a very special appearance but they also let in light, air and offer additional energy-efficiency. When considering the latter, there are several points to keep in mind. There are a number of ways to make sure that your windows save you as much money as possible.


Low-E, or Low Emissivity coatings are used to limit energy loss through the windows. These layers are thin and almost undetectable, and they help reduce heat flow and thereby make your windows more efficient. The radiant heat remains on the side from which it originates. What this means is that, in the summer, the heat stays outside and, in the winter, the heat stays inside. Either way, you will spend less on your energy bill.

Energy Star Windows

These windows are a great investment if you current windows are not marked with the Energy Star label or if you are in the market for new windows. These windows are made using more energy efficient processes, and the products are also more efficient. They are designed to help you save on your energy bill (heating and cooling) while providing many other benefits. In some instances, you might also be able to enjoy a tax incentive such as rebates and sales tax exemptions.

Professional Installation

Whenever you’re installing a new window, it is always best to have a professional do the job for you. If you try the DIY approach, you might not fit the window perfectly, and this can make it less efficient than you’d like. It could let in the heat in the summer and allow heat to escape during the winter. With a professional window installation, you can be certain that your windows will be well-fitted, and you will enjoy maximum benefits.

The Right Kind of Insulation

Windows also need to be insulated, and there are a number of options including rubber weather sealing, draft snakes, caulking, and magnetic inserts. There are various effective methods of insulation that don’t need to cost a fortune either. The most important thing to remember is that the insulation on a window needs to be flawless in order to prove effective. It’s important to check the insulation on a regular basis and, if it’s showing signs of wear and tear, you should tend to this matter sooner rather than later.

Window Material

Different kinds of materials conduct heat and cold more or less effectively. The less conductive the material, the better for insulation. Vinyl is great at maintaining a moderate temperature. It doesn’t become nearly as hot as metal in the summer or ice cold in the winter. This means that the outside temperature will not be transmitted inside through the frame.

Hang Curtains in Your Home

Regardless of the type of windows you install in your home; you should consider hanging curtains. Keep them closed in the summer and this will help prevent the heat from the sun entering your home. Thick, dark curtains are best but, if you prefer, you can use lighter shades, blinds, or curtains. They may not be as effective, but they will reflect some of the sunlight and heat. They also add visual appeal.
