Many homeowners focus on remodeling their kitchens or bathrooms, but upgrading their windows can have a dramatic impact on comfort and efficiency. At the Ventura Home Show, Sean from American Window Concepts demonstrated how different types of glass affect indoor temperatures. His presentation made it clear that Low-E coatings are one of the most effective ways to reduce unwanted heat inside your home.

The Downside of Clear Glass

Sean showed how clear glass allows heat to pass through quickly. Using a radiometer, he illustrated how quickly the glass reached 98 degrees under direct light, causing the device to spin almost instantly. This example clearly illustrates why homes with outdated clear windows tend to overheat on sunny days, resulting in higher energy consumption and discomfort.

How Low-E3 and G340 Glass Perform

Low-E3 glass significantly slowed heat transfer, dropping the temperature to 78 degrees and stopping the radiometer from spinning. Sean also introduced G340 glass, which performed even better by keeping temperatures at 77 degrees. These advanced coatings are standard in top-quality brands like Anlin, Milgard, and Pella, helping reflect heat and maintain cooler interiors.

Time to Rethink Your Windows

 If your home still has clear glass windows, now is a great time to upgrade. New Low-E coated windows slow down heat gain, reduce energy bills, and create a more comfortable home environment. If you’re in Ventura or Long Beach, visit American Window Concepts offers free in-home estimates.
