Understanding Low-E Coatings and Their Impact on Energy Efficiency

When it comes to choosing the right type of windows for their properties, homeowners typically consider factors like aesthetics and functionality. However, apart from contributing to the style of your home, your windows can also have an impact on your home’s energy efficiency. In this blog, we are going to explore how low-E window coatings can be a cost-effective solution to help you save on energy consumption.What Are Low-E Coatings?

 

Low-emissivity coating is a technology created to better control the amount of ultraviolet and infrared light that passes through windows. A thin layer of metal or metallic oxide is applied on the glass, which helps control indoor temperatures more efficiently. Additionally, E-coatings can also reduce the damage caused by the excessive exposure to UV light, such as skin conditions or damage to furniture.

 

How Does E-Coating Contribute to Energy Efficiency?

 

Cooling and heating systems are commonly the villains of energy bills. This is because they generally operate continuously to keep your indoor temperatures comfortable, especially during extreme weather conditions such as freezing winters or scorching summers. For that reason, finding ways of relying less on your HVAC systems can significantly reduce your energy costs and e-coating can help with that.

 

So how does it work? In order to comprehend how E-coating works, it is important to understand the solar energy spectrum and the different types of wavelengths we get from the sun. UV light is the wavelength that causes material to fade. Infrared light is the wavelength responsible for heating and visible light is the spectrum that we are able to see. When E-coating is applied on glass, it reflects part of the ultraviolet and infrared radiation while still allowing visible light to go through. This helps you manage indoor temperatures more efficiently, keeping warmth inside your home during the winter and preventing excessive heat to reach your place in the summer.

 

E-coating windows reduce energy consumption by preventing you from heavily relying on cooling and heating systems to keep your home comfortable. This not only makes them a cost-effective investment but also an environmentally friendly solution.

 

Which Type of Low E-Coating Should I Choose?

 

Choosing the right type of E-coating for your windows will depend on where you live as well as your cooling and heating needs. For instance, single Low-E coatings offer one layer of protection that is typically suitable for most regions in Canada. Double low E – coatings come with an extra layer of protection while triple E-coating can block up to 95% of UV rays. Experienced professionals can help you determine what option is ideal for your place and which alternatives can be considered within your budget.
