When you run a business, glass isn’t just something you look through – it’s part of your brand, your customer experience, and your building’s safety. Whether it’s a shopfront window, office partition, or industrial panel, choosing the right glass affects everything from security and temperature control to maintenance and energy costs.
From laminated safety glass that resists impact to double glazing that improves efficiency, each type of glass serves a different purpose – and knowing which one to use can save you time and money.
Here’s a clear comparison of the most common types of glass used in Auckland’s commercial and industrial spaces, how they differ, and when each is worth the investment.
Laminated glass is made by bonding two or more layers of glass together with a clear plastic interlayer. When it breaks, the interlayer holds the shards in place – so the glass cracks but doesn’t shatter into sharp pieces.
Why it’s great:
- Excellent for security – harder to break through.
- Reduces outside noise.
- Offers UV protection to reduce fading of interiors.
- Stays intact when broken, preventing injuries.
When to choose it:
Perfect for shopfronts, public-facing areas, or spaces where safety and security are a top priority – protecting people and property from accidental or deliberate impact.
Price range:
Slightly more expensive than standard float glass, but often cheaper than double glazing. The safety benefits easily justify the extra cost.
Toughened (Tempered) Glass
Toughened glass is heat-treated to increase strength by up to five times compared with regular glass. When it breaks, it shatters into small, blunt fragments instead of sharp shards.
Why it’s great:
- High impact resistance.
- Withstands temperature changes – ideal for kitchens, bathrooms, and outdoors.
- Safe break pattern reduces injury risk.
When to choose it:
Perfect for areas where glass is frequently touched or knocked – such as shop windows, balustrades, or patio doors.
Price range:
Slightly more expensive than laminated glass, but a worthwhile upgrade for durability and aesthetics.
Double Glazing
Double glazing consists of two panes of glass separated by a sealed air (or gas) gap. This acts as an insulator, keeping heat in during winter and out during summer.
Why it’s great:
- Energy-efficient – helps lower power bills.
- Reduces outside noise.
- Adds a layer of security.
- Available with laminated or toughened options for extra protection.
When to choose it:
Ideal for Auckland homeowners looking to improve comfort and reduce condensation, especially in bedrooms, lounges, and offices.
Price range:
One of the more expensive options upfront but offers long-term savings on energy and heating.
Laminated Panels
Laminated panels are thicker, multi-layered sheets used for large façades or specialised designs. They can include decorative tints, coatings, or acoustic insulation layers.
Why it’s great:
- Customisable thickness and finish.
- Superior strength and sound control.
- Can meet safety and performance codes for high-rise or commercial spaces.
When to choose it:
Used when standard glass can’t handle the size or load. Common in office buildings, shopfronts, and balustrade walls.
Price range:
The most expensive option due to material complexity and installation requirements – but essential for structural and safety compliance.
