Not all window glass offers the same level of protection. Compare tempered, laminated security, and armoured shield glass and see each option performs in terms of safety, security, durability, and overall residential use.
Security Glass
A multi-layered glass unit with an interlayer that helps hold the glass together when broken. Ideal for improved security and better sound control.
Primary purpose:
Safety + retained barrier after breakage + better security/acoustics.
How it breaks:
Cracks, but fragments adhere to interlayer and usually stay in place.
Burglary resistance:
Stronger; stays in frame longer and delays entry.
Ballistic resistance:
Usually none unless specially engineered/tested.
Sound reduction:
Reduces traffic and outdoor noise with superior sound dampening.
UV blocking:
Excellent – blocks up to 99% of harmful UV rays.
Typical weight:
Similar to Triple pane.
Thermal performance:
Good when built into Low-E sealed IGU.
Retrofit suitability:
Good to very good, depending on weight and frame system.
Relative cost:
$
Best use cases:
Ground-floor windows, sidelites, large glass near doors, security-conscious homes, noise-sensitive rooms.
Main downside:
Heavier than tempered may have restricted use for some larger window openings.
Shield Glass
A high-security glazing solution built with multiple layers for advanced protection against severe impact and attack.
Primary purpose:
High forced-entry resistance – unbreakable.
How it breaks:
Multi-layer system absorbs impact; may crack/spiderweb but designed to resist penetration.
Burglary resistance:
Very strong – high protection against threats.
Ballistic resistance:
Yes, when rated/tested to UL 752 or similar.
Sound reduction:
Can be good due to mass/thickness, but not usually selected for acoustics first.
UV blocking:
Often good, but depends on build-up/interlayers.
Typical weight:
Very high.
Thermal performance:
Can be built as insulated security glazing, but assembly becomes heavy/expensive.
Retrofit suitability:
Good to very good, depending on weight and frame system.
Relative cost:
$$$$$
Best use cases:
Panic rooms, executive residences, high-threat properties, specialized security projects.
Main downside:
Weight and thickness limiting some larger sized openings.
Tempered Glass
A standard safety glass option designed to break into small, less hazardous pieces on impact. Best suited for homeowners seeking reliable everyday performance.
Primary purpose:
Safety glazing; stronger than annealed glass; safer break pattern.
How it breaks:
Shatters into many small pieces.
Burglary resistance:
Weak once broken; generally easier to breach.
Ballistic resistance:
None.
Sound reduction:
Basic / average.
UV blocking:
Limited unless coated.
Typical weight:
Moderate.
Thermal performance:
Good when built into Low-E sealed IGU.
Retrofit suitability:
Excellent.
Relative cost:
$$
Best use cases:
Bathrooms, doors, low-risk locations needing safety glazing.
Main downside:
Breaks out completely once compromised allowing easy entrance for intruder.
