Windows provide warmth, light, and safety in any space. They largely act as a natural light source, leading to cozy, comfortable buildings. However, when the sunlight is too strong, it could have some uncomfortable and destructive effects. Too much heat gain, for instance, will leave you spending heavily to cool your home. 
A variety of window treatments can curb the effects of intense sunlight and help keep your energy costs low while making your house more livable. At Coastal Glass Tinting, we specialize in fixing high-quality window films within the Southeastern Carolina area. In this post, we will discuss how to block the heat from penetrating windows.

The Effects of Heat on Windows

Heat exposure can affect glass windows in a variety of ways, such as: 

  • Expansion and contraction. Glass windows generally expand when the temperatures are high and contract when the high temperatures subside. Over time, this can cause wear and tear, leading to potential cracks and seal failures. 
  • Cracking and breaking. Extreme heat could cause glass windows to crack or shatter. 
  • Fading. Infrared heat from the sun and ultraviolet (UV) rays can cause discoloration or fading of windows. 
  • Lower energy efficiency. When plenty of heat is conducted into your house, the heating and cooling system works harder, leading to higher energy costs.  
  • Loss of insulation. The insulating properties of windows deteriorate after continued heat exposure. This means that they are unable to offer enhanced protection against outdoor temperatures.  

The Benefits of Window Tinting for Heat Reduction

Window tinting is one of the most efficient ways of blocking heat from windows. This involves installing window films directly on the glass windows. The main advantages of using window films for heat reflection reduction:

Solar Heat Reflection

Window heat blocker films can block and reflect a significant portion of the sun’s solar energy. When only a small fraction of heat enters your home, the indoors remain cool and comfortable. 

Energy Efficiency

When heat control window films prevent excessive heat gain, they reduce reliance on air conditioning systems. This saves energy costs and is environmentally friendly. 

UV Radiation Protection

Heat-reducing window films block harmful UV rays that could damage your furniture, artwork, or flooring, among other interior furnishings. This means that your assets get to maintain their integrity and color for a very long time. 

Enhanced Privacy and Security

With tinted windows, it is difficult for someone outside to see into your home. This gives your home an added level of privacy as well as security, which could make you and other occupants feel more comfortable. 


There are several types of tints you could choose for your house, allowing you to choose the level of light and heat control that best suits your needs and preferences. 

Different Types of Window Tinting

The main types of window heat blocker tints you can install at your home include: 

  • UV-Blocking Window Films. These tints are specifically designed to block UV rays and protect your interior furnishings.
  • Low-E (Low Emissivity) Window Films. These are energy-efficient tints that help to curb heat loss during the winter and heat gain during the summer. They enhance insulation and help to keep your home’s heating and cooling costs low. 
  • Solar Control Window Films. These are tints designed to block excess solar heat and lower the sun’s glare. They help to maintain comfortable indoor temperatures while also protecting your interior furnishings. 
  • Frosted or Etched Window Films. Etched or frosted tints create a frosted glass appearance, ensuring maximum privacy without impeding light penetration. They help to improve the privacy and aesthetic appeal of your home. 
  • In many cases…We have film options that offer all benefits in one!
