Homeowners should be aware of the danger of solar heat gain, because if you don’t know about a problem, you can’t do anything about it. What is solar heat gain? It is the process by which the sun heats up your home. For example, the UV rays of the sun can easily pass through the windows in your home. Once inside, the UV rays are absorbed by the interior surfaces of your home where they are converted to heat. To stop the onslaught of UV rays before they can heat up your home and cause problems for your AC system, you have to do something to prevent them.

Thermal Curtains

A thermal curtain will have a thick layer of batting and typically a layer of metal foil. Together, these components will create a thermal barrier which will prevent heat from the sun from passing into your home even as they stop the cold air from your AC system from passing out your windows. The problem with thermal curtains is that in order for them to do their job, you have to block off your windows with the curtains. Thus, you will not be able to let in light or see out of your windows. 

Window Films

If you want to make use of natural light, and if you want to keep your windows clear to open up the space in your home, you probably want to steer away from thermal curtains. If you can filter UV rays out of the light coming into your home, you can stop solar heat gain in its tracks. To achieve such filtering, you really need nothing more than window films. Window films will come with a reflective coating that will deflect much of the sun’s UV rays before they can enter your home. By filtering out UV light, window films can decrease your cooling costs by up to 23%

Windows account for up to 40% of cooling costs. This number is not an immutable fact. Instead, you should see window improvements as an opportunity to decrease your cooling costs. Upgrades like thermal curtains and window films are inexpensive and can have a big impact on how much you pay to keep your home cool. Anything you can do to keep your home from heating up in the first place will help you to keep your cooling costs down by reducing the demand on your AC system. If costs are still too high, consider contacting an AC repair company, such as Atlantic Heating and Cooling, to see if your system needs extra help.
