What’s the Difference Between All These Types of Glass?
A homeowner-friendly guide to window and shower glass options
Not all glass is the same. The type of glass you choose affects safety, efficiency, sound control, privacy, and durability, especially in windows, doors, showers, and railings.
Float (annealed) glass
Float glass is the basic starting point for many glass products. It’s smooth and clear, but it can break into sharp shards, which is why it’s typically upgraded or processed for safety in many applications.

Tempered glass (safety glass)
Tempered glass is heat-treated to increase strength. When it breaks, it typically crumbles into smaller pieces instead of large, sharp shards, making it a common choice for shower doors and other safety-required areas.

Laminated glass
Laminated glass includes a bonded interlayer that helps hold the glass together if it cracks. It’s often used when added security, impact resistance, or safety is a priority.

Insulated glass (double-pane / IGU)
Most modern windows use an insulated glass unit (IGU), which is two panes separated by a spacer, often with gas-filled and sealed edges. Insulated glass improves comfort and efficiency compared to single-pane.

Low-E glass
Low-emissivity (Low-E) glass uses a thin coating to improve efficiency, helping reduce heat transfer while still allowing natural light. Many energy-efficient window options include Low-E as part of the glass package.

Obscured / privacy glass
Obscured glass includes etched, frosted, patterned, or textured finishes that increase privacy while still allowing light, popular for bathrooms and entry sidelites.
