Energy efficiency is no longer a luxury — it’s the expectation.
From San Francisco’s historic homes to modern commercial buildings in San Jose and Oakland, property owners across the Bay Area are feeling the pressure to reduce energy costs, meet sustainability standards, and increase comfort year-round.
But many buildings still rely on outdated windows that leak air, invite UV damage, and drive up utility bills.
At AFR Windows, we specialize in Energy Star®-rated window glazing systems engineered for performance — not just appearance. Whether you’re replacing fogged glass, upgrading to modern glazing, or designing from scratch, we’ll help you meet today’s energy expectations without sacrificing style or structural integrity.
Old or poorly glazed windows contribute to:
High heating and cooling costs
UV damage to flooring and furnishings
Indoor temperature imbalances
Increased condensation and mold risk
Non-compliance with California Title 24 energy codes
You shouldn’t have to choose between performance and aesthetics — and with AFR, you don’t have to.

Noise Reduction
Energy Savings
Cut Energy Bills Without Compromising Style
Home and building owners are getting smarter—and so are the windows we install. In a time where energy efficiency is no longer optional but essential, upgrading to ENERGY STAR® window glazing is one of the most effective ways to improve comfort, lower utility costs, and meet stringent building codes.
But choosing the right window glazing isn’t just about slapping a label on a piece of glass.
You need a solution that balances performance, style, code compliance, and long-term durability. That’s where AFR Windows comes in.
We Get It—You Want Efficiency That Works AND Looks Good
We’ve seen it all: drafty older windows that leak air like a sieve, overly tinted glass that makes your space feel like a cave, or improperly installed units that void manufacturer warranties.
You shouldn’t have to sacrifice style to get efficiency.
And you shouldn’t have to navigate complex ENERGY STAR requirements alone.
At AFR Windows, we specialize in installing high-performance ENERGY STAR window glazing systems for both residential and commercial properties. We help clients:
Choose the right glazing package for their climate zone
Understand the difference between double- and triple-pane options
Navigate code requirements like Title 24 and local green building ordinances
Maximize natural light without overheating the space
Ensure a clean, code-compliant install that stands the test of time
What Makes ENERGY STAR Window Glazing So Important?
ENERGY STAR-rated glazing systems are designed to:
🌡️ Improve insulation (U-Factor) – Keep heat in during winter and out in summer
☀️ Control solar heat gain (SHGC) – Let in light without the added heat
❄️ Reduce drafts – Better seals, frames, and glass technology mean no more uncomfortable cold spots
💡 Lower energy costs – By reducing your reliance on heating and cooling systems
🌎 Support sustainability goals – ENERGY STAR windows are often part of LEED-certified or green-building initiatives
Whether you’re working on a custom home, mid-rise office, or multifamily complex, energy-efficient glazing is not just a bonus—it’s a baseline expectation.
Residential Clients: Say Goodbye to Drafts and High Utility Bills
If you’re a homeowner, you’ve probably noticed it: certain rooms just don’t stay warm in the winter or cool in the summer. The culprit is usually old or poorly glazed windows.
Our ENERGY STAR residential glazing solutions are customized to your space, aesthetic, and comfort needs. We install:
Double-pane glass with Low-E coatings and argon gas fills for a powerful insulation barrier
Triple-pane options for clients in colder climates or mountain regions
UV-filtering coatings that protect your furniture and floors from fading
Frames that match your home’s character without sacrificing performance
We work quickly, cleanly, and with a deep respect for your property. Our crews treat your home like it’s their own—because we know how disruptive renovations can be.
Commercial Clients: Meet Codes, Cut Costs, and Impress Tenants
For commercial properties, ENERGY STAR window glazing isn’t just a smart move—it’s often a compliance requirement.
We’ve helped building owners and GCs install high-efficiency glazing systems that meet:
California’s Title 24 energy code
LEED and Green Globes program standards
Local sustainability ordinances and federal tax credit qualifications
Whether you’re upgrading a hotel, office park, school, or luxury apartment building, we guide you through:
Selecting the right visible light transmission and SHGC balance
Ensuring proper thermal breaks and spacer systems
Coordinating logistics and permitting with other trades
Minimizing tenant disruption with professional, on-time work
What Happens When Glazing Goes Wrong?
Choosing the wrong glass—or the wrong installer—can mean:
🚫 Fogged-up or failed glass units
🚫 Higher-than-expected utility bills
🚫 Rejected inspections due to non-compliance
🚫 Unhappy homeowners or tenants
Even ENERGY STAR-rated glass won’t work if it’s improperly installed or mismatched to the environment. That’s why you need a team who understands both the code and the craftsmanship.
