Types of Glass

Understanding your options is important to us, the following information hopefully will help in your decision which type of glass to use when building codes are not a determining factor. If you have any additional questions, feel free to ask one of our expert sales representatives. Consider these pros and cons of annealed, tempered, and laminated glass.

Laminated

Laminated glass is a type of safety glass. Laminated glass is basically a sandwich made up from 2 pcs of annealed or tempered glass with a plastic interlayer. Rather than shattering like tempered glass, laminated glass stays together after it breaks.

 

Pros:

Lead Times: Laminated glass is a stock item and can be cut same day in most circumstances.

Tints: Stock tints available in Bronze, Grey, White and Green.

Cons:

Strength: Laminated glass is not as strong as tempered glass therefore, small openings are best for this use.

Annealed

Most commonly used type of glass. Also called standard.

Pros:

Cost: Annealed glass is less expensive than both laminated and tempered glass.

Lead Times: Annealed glass can be cut same day in most cases.

Cons:

Safety: If broken, annealed glass breaks into sharp glass shards and splinters that can cause serious injury and property damage.

Tempered

Pros:

Tempered glass is about four times stronger than annealed glass.

Tiny pieces of broken safety glass are unlikely injure you, making them far safer than the large shards of glass that result when annealed glass breaks.

Cons:

Tempered glass cannot be cut, drilled or altered after the tempering process.. 

Lead Times: Two weeks is the standard lead time for tempered glass.

Spontaneous failure: The tempering process that gives safety glass strength may also cause it to shatter, seemingly out of nowhere.

Distortion / Warping: Tempered glass sometimes develops roller waves, causing reflected images to distort. Narrow pieces may warp in the tempering process.
