How Does Low-E & Argon Gas 
Increase Efficiency?

People who are looking for the best replacement windows to increase energy efficiency have probably heard about Low-E glass. Low-E, which is short for Low Emittance, is used to describe a coating that can be applied to glass. Low-E coating is near colorless and non-toxic, so it won’t affect the safety or appearance of your windows.

Argon gas is a colorless, odorless, non-toxic gas that's used to fill the spaces between panes of glass in double or triple-glazed windows and doors to improve their thermal insulation and energy efficiency. 


What is Low-E Glass?

Low-E glass has a microscopically thin, transparent coating that is much thinner than human hair and reflects long-wave infrared energy (or heat). This coating allows natural light to enter the home while deflecting UV rays and infrared light back out into the environment. Some Low-E’s also reflect significant amounts of short-wave solar infrared energy.

What is Argon Gas?

Argon is denser than air and slows the transfer of heat from inside to outside, which can help maintain comfortable indoor temperatures and reduce energy costs. When used in conjunction with a low-emissivity (Low-E) glass coating, argon gas can also help bring the window's temperature closer to room temperature.

What are the benefits to Low-E and Argon?

Better Insulation

According to the EPA, losing or gaining heat through windows accounts for up to

30% of the energy people spend on heating and cooling their homes.

Consequently, the EPA recommends updating and replacing windows so that

homes are better insulated against seasonal changes.

Lower Energy Bills

What would your energy bills look like if you spent 30% less on accounting for inefficient windows and doors? According to the U.S. Energy Information Administration, the average household spends $115 per month on energy costs. This amounts to $414 in savings each year.

Greater Comfort

You can experience much greater comfort and convenience from better insulation with energy-efficient glass windows and doors. With reduced energy transfer, your home will be able to maintain temperature for longer, giving your air conditioner a much needed rest during Florida's summer months. 

Asset Protection

Did you know that the UV rays coming in through your windows damage your belongings over time? This may include rugs, paintings, and furniture. Low-E glass reduces UV-ray penetration, which can prevent the early aging of your belongings.
