Laminated Glass

Glass with interlayers for safety, sound control, security, and impact resistance.

Laminated glass bonds two or more glass plies with an interlayer that holds fragments together after breakage. It is specified for safety, hurricane impact, security, acoustic control, sloped glazing, and overhead conditions. Performance depends on glass thickness, heat treatment, interlayer type, interlayer thickness, edge support, and whether the assembly is part of an IGU.

Configurations

How It Comes

Safety Laminated

Standard laminated makeup for human-impact safety and post-breakage retention.

Impact Laminated

Tested glass and interlayer assembly for wind-borne debris regions.

Acoustic Laminated

Special acoustic interlayer or asymmetric plies to reduce sound transmission.

Security Laminated

Thicker interlayers or multiple plies for forced-entry delay and protection.

Applications

Where It's Used

Doors And Sidelites

Laminated Glass products are commonly selected for doors and sidelites where the product configuration, performance rating, and installation condition fit the project.

Coastal Impact Zones

Laminated Glass products are commonly selected for coastal impact zones where the product configuration, performance rating, and installation condition fit the project.

Sound-Sensitive Rooms

Laminated Glass products are commonly selected for sound-sensitive rooms where the product configuration, performance rating, and installation condition fit the project.

Overhead Or Sloped Glazing

Laminated Glass products are commonly selected for overhead or sloped glazing where the product configuration, performance rating, and installation condition fit the project.

Selection Guide

How To Specify It

Use these checkpoints when comparing quotes, reviewing submittals, or deciding whether this product type fits the opening.

Interlayer Type And Thickness

Compare interlayer type and thickness across manufacturers before selecting a laminated glass. Small differences here often change installation cost, serviceability, or long-term performance.

Impact Or Safety Certification

Compare impact or safety certification across manufacturers before selecting a laminated glass. Small differences here often change installation cost, serviceability, or long-term performance.

Edge Support And Drainage

Compare edge support and drainage across manufacturers before selecting a laminated glass. Small differences here often change installation cost, serviceability, or long-term performance.

Acoustic Target

Compare acoustic target across manufacturers before selecting a laminated glass. Small differences here often change installation cost, serviceability, or long-term performance.

Glass Makeup

Annealed / Heat-Strengthened Glass Laminated Glass

Base glass plies provide optical clarity and can be heat-strengthened where additional strength is needed without full tempering.

Advantages
  • Clear baseline option
  • Flexible in IGU makeups
  • Cost-effective
Considerations
  • Not safety glazing unless treated or laminated
  • Breakage behavior varies
  • Thermal stress must be reviewed

Glass Makeup

Tempered Safety Glass Laminated Glass

Tempered glass is heat-treated for strength and safety breakage behavior in code-defined hazardous locations.

Advantages
  • Required for many safety locations
  • Higher strength than annealed
  • Small-fragment breakage
Considerations
  • Cannot be cut after tempering
  • Spontaneous breakage risk is low but real
  • No post-breakage retention by itself

Glass Makeup

Laminated Glass Laminated Glass

Laminated glass uses an interlayer to retain broken glass and improve safety, impact, security, or acoustic performance.

Advantages
  • Post-breakage retention
  • Acoustic benefits
  • Impact and security options
Considerations
  • Higher cost and weight
  • Edge protection matters
  • Interlayer selection is performance-specific

Glass Makeup

Coated / Low-E Glass Laminated Glass

Coated glass controls radiant heat transfer, solar gain, glare, and appearance in insulated glass units.

Advantages
  • Improves energy performance
  • Climate-specific options
  • Can reduce fading and glare
Considerations
  • Appearance varies
  • Surface location matters
  • Wrong SHGC can hurt comfort

Glass Makeup

Spacer and Seal System Laminated Glass

The spacer and seal hold IGU panes apart, retain gas fill, and influence edge condensation and long-term durability.

Advantages
  • Warm-edge options improve comfort
  • Critical to IGU service life
  • Supports gas-filled cavities
Considerations
  • Seal failure causes fogging
  • Cheap spacers increase edge heat loss
  • Compatibility with frame drainage matters

Project Coordination

Details To Confirm Early

01

Confirm code-required safety glass

Doors, sidelites, low glass, bathrooms, stairs, and overhead conditions often require tempered or laminated safety glazing.

02

Coordinate glass with frame capacity

Thicker, laminated, or triple-pane units add weight and thickness that must fit the sash, stops, setting blocks, and hardware.

03

Review orientation and comfort

U-factor, SHGC, visible transmittance, glare, and interior surface temperature should match climate and exposure.

Product Questions

Common Questions

What should I compare first when selecting laminated glass?

Start with the operation or glass makeup, then verify performance ratings, installation conditions, accessory compatibility, and warranty limits for the exact product series.

Can laminated glass be used in any opening?

No. Size, exposure, code requirements, frame capacity, hardware, and installation details determine whether a product is appropriate for a specific opening.

What documents should I ask for before ordering?

Request product data, installation instructions, warranty terms, available test reports, and shop drawings for custom sizes, large assemblies, or code-sensitive conditions.
