2 Ways to Improve the Energy Efficiency of Old Commercial Windows

If the windows in your commercial building were installed a couple of decades ago, they’re not going to be that energy efficient. Old windows can bring down the energy efficiency of your entire commercial building. Luckily, the energy efficiency of your commercial building can be improved through window retrofitting solutions.

1. Window Film

One of the easiest ways to improve the energy efficiency of the windows in your commercial building is through the application of window film. Window film offers a wide variety of benefits, such as reduced utility costs and protection against glare and protection from damaging ultraviolet rays.
Reduce Utility Costs
To start with, window tint helps repel heat away from your windows in the summer and helps keep heat locked inside of your building during the winter. It can help reduce your overall utility costs by 30 to 40%, which in a commercial building, can provide you with really big savings.
Protect Against Glare
Window film also reduces the glare from the sun inside of your building. It can soften the visible light that comes through your windows, so people inside of your building don't have to shield their faces from the sun whenever it is directly hitting the building.
Prevent Fading & Damage from UV Rays
It also helps protect everything inside of your building from the harmful effects of UV rays, which can fade furniture and carpeting. Too much exposure to UV rays is not good for people either. Window film helps reflect UV rays away from your building so they don't get inside and damage your building.
Window film typically lasts around two decades, so although it is not as permanent a solution as installing new windows in your commercial building, it is a solid long-term solution that will make your building more energy efficient without the installation of new windows in your commercial building.
Window film should be professionally installed on your building. Professional installation will ensure that the window film is cut properly to fit your windows and applied so no bubbles develop that could compromise the long-term integrity of your new window film.

2. Low-E Storm Windows

Another way to improve the energy efficiency of the windows in your old commercial building is through the installation of low-e storm windows. Low-E storm windows combine two different technologies, low-E windows and storm windows, to create a unique product that can be applied on top of your existing commercial windows to help control energy costs.
Low-E Glass
Low-E glass, or low emissivity glass, has a special coating that is designed to reduce the amount of infrared and ultraviolet light that comes through the glass. At the same time, low-E glass is designed to ensure that visible light is still transmitted through the glass. It is specifically designed to reflect long-wave infrared energy as well as some short-wave solar infrared energy away from your commercial building.
Storm Windows
Storm windows are applied over the top of existing windows. They can be installed on the inside or the outside of your windows; it really depends on the set-up of your existing windows. Storm windows are designed to help improve the energy efficiency of your existing windows. Storm windows will help reflect away ultraviolet rays and can help reduce the transmission of sound through your windows.
Low-E storm windows combine the energy efficiency properties of both low-E glass and storm windows into one product that will provide your building with a strong layer of protection that will help reduce your overall energy costs.
You don’t have to change out all of the windows in your old commercial building to improve the energy efficiency of your building and reduce your overall utility costs. Window film as well as low-E storm windows are two solutions that work well in commercial spaces and should help you achieve a more energy efficient building without having to invest in new windows for your entire building.
