Homeowners in St. Louis know that the weather can be unpredictable—hot, humid summers and cold, windy winters put serious demands on your home’s windows. Choosing Energy Star®–certified windows is one of the smartest ways to improve comfort, reduce energy bills, and protect your investment.
At Viviano Windows, we help St. Louis homeowners understand what Energy Star windows really mean and how they can make a noticeable difference year-round.

Energy Star windows are independently tested and certified to meet strict energy-efficiency guidelines set by the ENERGY STAR program. These standards ensure windows perform better than average models when it comes to insulation and heat transfer.
Key features of Energy Star windows often include:
Double- or triple-pane glass
Low-E (low emissivity) coatings
Argon or krypton gas fills between panes
Advanced frame materials designed to reduce heat loss

St. Louis sits in a mixed-climate zone, meaning homes must handle both heating and cooling efficiently. Energy Star windows are specifically rated for regional climates like ours.
Benefits for St. Louis homeowners include:
Lower energy bills during extreme summer heat and winter cold
Improved indoor comfort with fewer drafts and hot spots
Reduced strain on HVAC systems, extending equipment lifespan
Better moisture control, helping prevent condensation issues

Installing Energy Star windows isn’t just about saving money—it’s about improving your entire living environment.
Some of the biggest advantages include:
Increased home value and curb appeal
Enhanced noise reduction from traffic and neighborhood sounds
Protection against UV rays that fade furniture and flooring
Potential eligibility for tax credits or energy rebates
