Available Glass Edges
Flat Polished Edge
A clean, machine-polished edge that offers a smooth, finished look. Essential if the edges of your annealed glass will remain visible after installation.
Beveled Polished Edge
A masterfully angled cut along the perimeter. This framing effect is perfect for decorative windows, cabinet doors, or elegant tabletops.
Extra Options & Customizations
Every project is unique. We provide precision radius corners, cutouts, and drilled holes so your annealed glass is perfectly fitted to your frame or furniture.
The Ultimate Machinable Glass
Important Note: Unlike tempered glass, annealed glass CAN be cut, drilled, or altered even after it is manufactured. This makes it the most flexible glass type for custom DIY projects.
Precision drilled openings to seamlessly accommodate cabinet hinges, specialized latches, or locks.
Smoothly curved corners designed specifically to fit perfectly into custom rounded or specialty architectural frames.
Intricate edge-notching allowing your glass to flawlessly wrap around unique custom frames or structural obstacles.
How To Measure
A flawless replacement starts with precise measurements. Follow our guide below to ensure your new glass pane fits effortlessly into your existing frame.
Use a Metal Tape Measure
Never use flexible cloth tapes. Always ensure your rigid metal tape is held perfectly straight and taut across the frame.
Frame Tolerances
When fitting glass into a tight frame, manually deduct a 2mm–3mm (1/8″) tolerance so the pane slots in easily without cracking.
Check for Out-of-Square
Measure across diagonals to ensure your opening is perfectly square before ordering standard rectangular panes.
Submit in Inches
To ensure a streamlined, error-free manufacturing process across our USA facilities, please submit all final dimensions in standard inches.

Frequently Asked Questions
What is annealed glass?
Annealed glass is the standard, everyday glass used in windows and picture frames. It is cooled slowly during the manufacturing process, which relieves internal stress and allows it to be cut and drilled easily.
Can I cut annealed glass myself?
Yes! Unlike tempered glass, annealed glass can be cut, drilled, and polished after it has been manufactured. This makes it the top choice for DIY hobbyists.
How does annealed glass break?
When broken, annealed glass shatters into large, sharp, jagged shards. For this reason, it should not be used in high-traffic areas or places where human impact is likely.
Is annealed glass safe for doors or showers?
No. Building codes legally require tempered “safety glass” for doors, sidelights, and shower enclosures. Annealed glass is best suited for cabinet doors, picture frames, and windows that are high off the ground.
Is annealed glass cheaper than tempered glass?
Yes, because it skips the secondary extreme heating and cooling processes, annealed glass is highly cost-effective and budget-friendly for standard home projects.
What is the turnaround time?
Most custom glass orders are manufactured and shipped within 9–11 business days.

What is Annealed Glass?
If you are wondering what is annealed glass, it is essentially standard, everyday glass. During the manufacturing process, the glass is heated and then subjected to a highly controlled, slow cooling process (known as annealing).
This slow cooling relieves internal stresses within the glass. Because it isn’t heat-treated for extreme strength, annealed glass retains a key advantage: it can be easily cut, drilled, polished, and custom-machined after it is manufactured, making it highly versatile for custom home projects.
The Classic Annealed Window
For decades, the standard annealed window has been the foundational choice for residential and commercial spaces. Because it offers perfect optical clarity and is highly cost-effective, it is widely used in areas where high-impact safety glass is not legally required by building codes.
Beyond standard windows, annealed glass is the ideal choice for:
- Cabinet doors and decorative shelving
- Picture frames and display cases
- Small decorative tabletops
- Basement or high-level windows where human impact is highly unlikely
Annealed vs Tempered Glass: Making the Right Choice
When shopping for glass, the most common question we get is regarding annealed vs tempered glass. Choosing the right one is critical for both your budget and your safety.
While annealed glass is standard, tempered glass is a “safety glass” that has been rapidly heated and cooled, making it up to five times stronger. The most important difference between the two is how they break.
| Feature | Annealed Glass (Standard) | Tempered Glass (Safety) |
|---|---|---|
| Strength | Standard durability for everyday use. | 4x to 5x stronger than standard glass. |
| How It Breaks | Breaks into large, sharp, jagged shards. | Shatters into small, blunt, pebble-like pieces. |
| Customizability | Can be cut, drilled, or reshaped at any time. | Cannot be cut or altered after the tempering process. |
| Best Uses | Picture frames, cabinet glass, standard out-of-reach windows. | Shower doors, patio doors, large glass dining tables. |
Note: If you are replacing glass in a door, a shower enclosure, or a window close to the floor, building codes require tempered safety glass to prevent injury.
