Laminated glass and toughened glass are two common types of safety glass used in New Zealand homes. Both are designed to reduce injury risk, but they differ in how they are made and how they behave.

When choosing glass for your home – whether for windows, shower units, glass balustrades, or glass pool fencing – it’s important to understand the differences.

Laminated Glass

Laminated glass is made by bonding two or more layers of glass with a plastic interlayer (usually PVB). Even if it breaks, the fragments stick to the interlayer and the pane usually stays in place.

Advantages:

• Holds together when cracked (spider-web pattern).

• Blocks up to 99% of UV radiation.

• Provides sound insulation – great for homes near busy roads.

• Offers extra security since intruders must cut through the plastic layer.

Common uses in NZ: skylights, overhead glazing, security windows, and large shopfronts.

Toughened Glass

Toughened glass (also called tempered glass) is a single pane heated and rapidly cooled to make it 4–5 times stronger than normal glass.

Advantages:

• Very high impact strength.

• Withstands thermal stress (hot/cold changes).

• If it breaks, it shatters into small blunt granules, reducing injury risk.

Common uses in NZ: frameless shower screens, pool fences, sliding doors, and many balustrades.

Key Differences

• Strength: Toughened glass is stronger. Laminated glass focuses on retention and extra features.

• Breakage: Toughened shatters into small cubes; laminated cracks but stays intact.

• Safety: Both are Grade A safety glass. Laminated is better overhead; toughened is better for impacts.

• Sound/UV: Laminated reduces noise and blocks UV. Toughened does not.

• Cost: Laminated is more expensive due to its multi-layer structure.

For official compliance info, see the NZ Building Code – Hazardous Building Materials (Clause F2) and NZS 4223 Glazing Standards.

Applications in Kiwi Homes

• Bathrooms: Toughened glass is used in showers and bath enclosures.

• Pools: Toughened glass panels are standard for fences, meeting NZ pool safety rules.

• Balustrades: Framed systems may use toughened; frameless must use toughened laminated to meet NZS 4223.

• Skylights: Laminated is recommended to prevent glass falling inside and for UV/sound protection.

Summary

• Choose toughened when you need strength and safe shatter – like showers, pool fences, and doors.

• Choose laminated when you need the glass to stay in place, plus UV and sound benefits – like skylights, windows facing busy streets, or security glazing.

• In some cases, use both together (toughened laminated).

Both types are compliant and safe. The “right” choice depends on your project.

FAQ

Which is stronger, laminated or toughened glass?
Toughened glass is generally 4–5 times stronger than ordinary glass. Laminated is not inherently stronger, but it stays intact when cracked.

Is laminated safer than toughened?
Both are safe (Grade A). Laminated holds glass in place; toughened shatters into harmless pieces.

Where is safety glass required in NZ homes?
In doors, bathrooms, low-level glazing, balustrades, and overhead windows. See NZ Building Code F2.

Does laminated provide better sound and UV protection?
Yes. The interlayer reduces noise and blocks most UV rays.

Which is more expensive?
Laminated usually costs more. Toughened is cheaper for standard applications, laminated is worth it where noise, UV, or security are priorities.

Frameless shower screens are popular across New Zealand for a clean, modern look that opens up the bathroom. A common concern is whether the glass is fragile without a frame. The short answer: when you use properly specified glass and a professional install, it’s built to handle daily life.

How frameless shower glass is made

Most quality shower units use 10–12 mm toughened (tempered) glass. During manufacturing, the glass is heated and rapidly cooled to increase strength to around four to five times that of ordinary glass. Some projects opt for laminated or toughened-laminated panels where retention (the glass staying in place if cracked) is important.

• Toughened glass: high impact resistance; if failure occurs, it crumbles into small blunt particles rather than sharp shards.

• Laminated glass: multiple layers bonded with an interlayer; if cracked, the panel holds together instead of falling away.

Is it really safe?

Yes—provided the system is specified and installed correctly. That means compliant glass, quality hardware, and correct fixing points. A professional installation prevents point-loading or uneven pressure that can stress a panel over time.

• Gate and hinge quality matters in wet areas too. We use hardware systems on our glass gate system range that are built for repeated use and smooth operation.

When can problems happen?

Even strong glass can be compromised by avoidable issues:

• Edge impacts: the most vulnerable area of any glass panel is the edge or corner.

• Incorrect installation: misaligned fixings or poor waterproofing can create stress points.

• Damaged or low-quality hardware: worn hinges or brackets may transfer uneven loads.

• Existing chips or cracks: any visible damage should be assessed and remedied promptly.

If you’re unsure whether a panel or hinge is still sound, contact us for a quick check: Get in touch.

Care and cleaning

• Wipe down with a soft cloth and mild cleaner; avoid abrasives and sharp tools.

• Check hinges and support brackets occasionally to keep them tight and true.

• Consider a glass coating solution if you want easier cleaning and less spotting.

Choosing glass for the rest of your home

If you like the clear, modern look in the bathroom, you can carry the theme through the home:

• Outdoor safety and sightlines: glass pool fencing

• Decks and stairs: glass balustrade

Keeping materials consistent often lifts overall value and makes spaces feel bigger.

FAQ

Will frameless shower glass shatter easily?
No. 10–12 mm toughened panels are engineered to withstand everyday impacts when fitted correctly.

If it breaks, is it dangerous?
Toughened glass is designed to crumble into small blunt pieces. Laminated and toughened-laminated options add retention if that’s a priority.

Can I DIY the installation?
We don’t recommend it. Waterproofing details, correct fixings and level alignment are critical. Use a professional installer.

What thickness should I choose?
Most frameless showers use 10–12 mm. We’ll recommend a spec based on layout, openings and hardware.

If you’ve got a pool at home in New Zealand, you’ll know how important it is to keep it safe – especially if there are kids around. By law, most backyard pools need to be fully fenced, and over the last few years, glass pool fencing has become the go-to choice for a lot of Kiwi families.

It ticks the boxes for safety, but also looks clean, modern, and keeps your backyard feeling open. Still, plenty of people ask the same questions: Isn’t glass a bit risky? What if it breaks? Is it a pain to keep clean?

Let’s run through the facts and clear up some of the common worries.

How Glass Pool Fencing Works

A standard glass pool fence is made from toughened (tempered) glass or laminated glass, usually around 10–12mm thick.

• Toughened glass is up to five times stronger than normal glass. If it ever does break, it shatters into blunt little pieces rather than sharp shards.

• Laminated glass has a safety layer in the middle, which means even if it cracks, it stays in place instead of falling out.

Your gate system is just as important – that’s where a solid glass gate system with proper stainless steel or aluminium hardware comes in. It keeps the entry sturdy and makes sure little ones can’t just wander into the pool area.

But Is It Really Safe?

The short answer – yes, as long as it’s done right.

Glass fences that meet the NZ Building Code are designed to handle knocks, bumps and years of Kiwi weather. Here’s why they’re safe:

• Super strong panels – 12mm glass can handle serious pressure.

• Meets NZ standards – every pool fence has to comply with NZS 8500, which is all about child safety.

• No climbing points – height and spacing rules stop kids from getting over.

• Quality fittings – strong hinges, posts and latches keep everything locked in tight.

So really, it’s not the glass you need to worry about – it’s making sure you buy from the right place and get it installed properly.

How It Stacks Up Against Other Options

• Wooden fences – cheaper upfront but can rot, warp, or need painting.

• Metal fences – solid but block your view and can rust.

• Glass fences – crystal clear, modern, low-maintenance and add value to your place.

If you’re also doing up a deck or balcony, you might want to check out our glass balustrades or handrails for a matching look.

Cost vs Value

Sure, glass fencing costs a bit more than timber or steel at the start. But with almost no upkeep, it pays off in the long run. Plus, it makes your property look sharper and can bump up the resale value.

Plenty of our customers also tie in matching shower units or DIY accessories to keep their home looking consistent.

FAQs – Straight Answers

Do kids get hurt if they run into the glass?
Not likely – toughened glass is built to take a hit. And if it ever breaks, it crumbles safely.

Doesn’t glass get dirty all the time?
You’ll get some water spots, but a quick wipe-down every now and then keeps it clear.

Do I need council sign-off?
Yep – every pool fence in NZ needs to comply with council rules.

Can I DIY it?
Honestly, don’t. Pool fencing is about safety and compliance. Best to get the pros in.

In New Zealand, extreme weather and strong winds are common occurrences, especially in coastal and mountainous areas. With the increasing frequency of storms and high winds due to climate change, wind resistance has become a crucial consideration for buildings and homes. As New Zealand’s leading glass supplier, GrandGlass.co.nz offers a range of wind-resistant glass solutions to help protect your home from the impact of harsh weather.

The Importance of Wind-Resistant Glass

Strong winds often impact buildings through the damage of windows and glass doors. Regular glass is vulnerable to breaking during storms, especially if it has not been specially reinforced. Wind-resistant glass, however, is specially treated to provide greater resistance to pressure and wind forces, making it ideal for withstanding the impact of storms.

The wind-resistant glass offered by GrandGlass uses tempered glass technology, significantly enhancing the glass's impact resistance and ensuring that it can endure greater pressure, keeping it intact in extreme weather conditions and reducing the risk of breakage.

Wind-Resistant Glass for Different Environments

1. Wind-Resistant Windows
   Installing high-quality wind-resistant windows is essential, especially during storm seasons in New Zealand. GrandGlass's windows are made from enhanced tempered glass, which ensures the windows remain stable and secure even during strong winds and storms.

   Explore our wind-resistant glass windows for more information.

2. Wind-Resistant Glass Door Systems
   Glass doors, particularly sliding or folding doors, are more vulnerable to damage during strong winds. GrandGlass offers glass door systems designed with stronger frames and tempered glass for greater stability and safety.

3. Glass Balustrades and Fences
   If your home is located near the coast or on a hill, wind resistance is even more important. The glass balustrades and glass fencing provided by GrandGlass are specially designed to withstand the impact of strong winds while maintaining a modern and stylish look.

4. Glass Pool Fencing
   For homes with pools, installing glass pool fencing is another effective way to ensure safety. Reinforced tempered glass fencing can withstand extreme weather conditions while keeping your pool area secure and stylish.

Advantages of GrandGlass’s Wind-Resistant Glass

• High Strength and Pressure Resistance: All of our glass products are made using high-strength tempered glass, reducing the risk of breakage during storms.

New Zealand is no stranger to wild winter weather – in early August 2025, heavy rain was sweeping across the country, followed by strong southerly winds and bone-chilling temperatures. Such conditions not only chill us to the bone but also test our homes and outdoor structures. For homeowners, a big question arises: How will features like glass pool fencing, glass balustrades, and even indoor glass shower units hold up against harsh winter weather?

Winter Wind & Rain: A Test for Outdoor Glass Fencing

Winter in NZ brings powerful gusts, torrential rain, and frosty cold snaps. These elements can wreak havoc on poorly made structures. Glass pool fences and balustrades, however, are designed to withstand such punishment. High-quality glass fencing is engineered with toughened safety glass and marine-grade stainless steel components, making it resilient against wind, rain, and corrosion.

High-Quality Glass Fencing Shines in Harsh Conditions

Quality installations use 12mm NZ-certified toughened glass and marine-grade stainless steel spigots. This combination resists rust, withstands high wind zones, and complies with NZ building codes. The safety glass shatters into small, blunt pieces if broken, reducing injury risk. Gates with self-closing and self-latching mechanisms add further safety, especially during windy conditions.

Quality Glass Shower Units: Cozy & Safe in Winter

High-quality shower enclosures made with 8-10mm toughened glass offer excellent durability and safety. They prevent leaks, retain warmth, and withstand temperature fluctuations. Coatings like nano or water-repellent treatments help maintain clarity and hygiene, especially important in winter when mold and moisture are more prevalent.

Grand Glass: Built for NZ Weather, Focused on Safety

Grand Glass products are tailored for New Zealand’s environment. All their fencing and shower systems use certified safety glass, marine-grade hardware, and optional anti-corrosion or easy-clean coatings. Their team ensures compliance with NZ standards and provides professional support and delivery nationwide.

Tips for Choosing & Maintaining Glass Fences and Showers

• Use NZ-certified toughened safety glass (12mm for fences, 8-10mm for showers)
• Opt for marine-grade stainless steel hardware
• Choose self-closing gates for pool safety
• Clean regularly and apply nano coatings if possible
• Check fixtures after storms for tightness and wear

Conclusion

Despite NZ's harsh winters, quality glass installations offer durability, safety, and style. Grand Glass delivers weather-resistant, certified, and low-maintenance solutions. Contact them today for expert advice or a free quote. Stay warm, safe, and stylish – no matter the weather!
