Choosing the right glass for your home involves a lot of variables — window type, glass coating, frame material, safety code, budget, and Atlanta’s specific climate challenges. At Glass Inc, we answer these questions every day for homeowners across Metro Atlanta. Here are the ones that come up most often.
Glass types and options
What types of residential glass does Glass Inc offer?
We install and service the full range of residential glass products:
- Low-E (low-emissivity) glass — has a thin metallic coating that reflects heat. Keeps your home cooler in summer and warmer in winter. This is the most popular upgrade we recommend for Atlanta homes.
- Tempered safety glass — required by Georgia building code in certain locations (shower doors, glass near doors, low windows). Four to five times stronger than standard glass and breaks into small, blunt pieces instead of dangerous shards.
- Laminated glass — two glass layers bonded with a plastic interlayer. Excellent for sound reduction (great for homes near I-285 or Hartsfield-Jackson flight paths) and UV protection. Stays intact when broken, providing a security barrier.
- Insulated glass units (IGUs) — double or triple pane windows with sealed air or gas-filled spaces between panes. The standard for energy efficiency in new construction and window replacements.
- Decorative glass — patterned, textured, frosted, and stained glass for privacy, aesthetics, and character. Popular in bathroom windows, front doors, and transom windows across Inman Park, Virginia-Highland, and other historic Atlanta neighborhoods.
What is the best glass for energy efficiency in Atlanta?
Low-E double-pane glass with argon gas fill is the best value for most Atlanta homes. The Low-E coating reflects solar heat gain during Georgia’s hot summers while retaining warmth during winter cold snaps. For south and west-facing windows that get heavy afternoon sun (common in Buckhead, Sandy Springs, and Roswell), solar control Low-E coatings provide extra heat rejection.
Triple-pane glass offers even better insulation but at a higher price point. It makes the most sense for homes with large window walls, sunrooms, or rooms that are consistently hard to keep comfortable.
Can you customize glass for unusual window shapes?
Yes. Custom fabrication is one of our strengths. We cut and shape glass to fit arched windows, circular windows, trapezoids, and other non-standard shapes commonly found in Atlanta’s older homes and custom new construction. We also create custom glass for specialty applications like glass railings, tabletops, and decorative panels.
Window replacement
How often should residential windows be replaced?
Most well-maintained windows last 15 to 25 years. However, several signs indicate you may need replacement sooner:
- Condensation between panes — this means the sealed insulating unit has failed and the gas fill has escaped. The window has lost most of its insulating value.
- Visible cracks or chips — any structural damage compromises safety and weather performance.
- Drafts near closed windows — you can feel air movement even when the window is shut. This indicates seal failure, frame deterioration, or both.
- Difficulty opening or closing — warped frames, broken hardware, or swollen wood frames from moisture damage.
- High energy bills — if your HVAC system runs constantly and you have older single-pane windows, replacement will often pay for itself within five to eight years through energy savings.
Homes built in the 1960s through 1980s across Decatur, East Atlanta, and other established neighborhoods are prime candidates for window upgrades. Many still have original single-pane aluminum-frame windows that are far below current energy standards.
How much does window replacement cost in Atlanta?
Costs depend on window type, size, glass options, and frame material:
| Window type | Approximate cost per window (installed) |
|---|---|
| Basic double-hung vinyl | $300 - $600 |
| Mid-range double-hung with Low-E | $500 - $800 |
| Premium wood or fiberglass frame | $800 - $1,500 |
| Custom or oversized windows | $1,000 - $2,500+ |
These are general ranges for Metro Atlanta. Glass Inc provides free in-home estimates with exact pricing for your specific project. Contact us to schedule a visit.
How long does window installation take?
A standard replacement window takes one to two hours per opening. For a whole-house replacement (10 to 15 windows), expect two to three days of installation work. Custom or oversized windows may require longer lead times for fabrication before installation can begin.
Maintenance and care
How do I maintain my glass to make it last?
Proper maintenance extends the life of your glass installations significantly:
- Cleaning: Use a dedicated glass cleaner (not household ammonia-based products like Windex, which can damage tint and seals). Apply with a clean microfiber cloth. Clean both interior and exterior surfaces.
- Seal inspection: Check the perimeter of each window annually for gaps, cracks, or separation between the glass and frame. Address any issues promptly to prevent water damage.
- Hardware lubrication: Apply silicone-based lubricant to window tracks, hinges, and locks once a year to keep them operating smoothly.
- Drainage: Make sure weep holes (small drainage slots at the bottom of the window frame) are clear and not blocked by paint, caulk, or debris.
What are the signs that my window seals have failed?
The most obvious sign is condensation or fogging between the panes of a double or triple-pane window. This means the sealed unit has lost its gas fill and moisture has entered the space. Other signs include:
- A milky or hazy appearance between panes that does not wipe away
- Visible moisture droplets inside the sealed unit
- Increased drafts or reduced sound insulation compared to when the window was new
Failed seals mean the window has lost a significant portion of its insulating value. In most cases, the insulated glass unit needs to be replaced (not the entire window frame, which saves cost).
Safety and building code
Where does Georgia code require tempered glass?
Georgia follows the International Building Code, which requires tempered or safety glass in these residential locations:
- All glass doors (including sliding, French, and shower doors)
- Windows within 24 inches of a door
- Windows with a bottom edge less than 18 inches from the floor
- Glass in shower and tub enclosures
- Glass in stairway landings and ramps
- Skylights and overhead glazing
If you are renovating or replacing windows in these locations, the new glass must be tempered. Glass Inc ensures all installations meet current Georgia code requirements.
What safety glass options are available beyond tempered?
- Laminated glass — stays intact when broken, held together by the plastic interlayer. Good for security applications, ground-floor windows, and locations exposed to severe weather.
- Security film — a retrofit option for existing glass. A thick adhesive film is applied to the interior surface, holding the glass together if it breaks. Less expensive than replacing the glass entirely.
- Impact-resistant glass — engineered for hurricane and storm zones. Combines laminated construction with heavy-duty framing.
For homes in areas with higher break-in risk (certain Atlanta neighborhoods report higher property crime rates), laminated glass or security film provides meaningful protection.
