Frequently Asked Questions

Is a single glass panel more energy efficient than double glazed glass?

No — a single glass panel is much less energy efficient than double-glazed glass.

Can I replace my existing window single glass to double glazed glass while using the existing window frames?

Yes, in many cases you can replace single glazing with double glazing using the existing window frames, but it depends on a few important factors:

If your existing frames are solid and deep enough, yes, you can retrofit double-glazed units into them. We can measure the rebate depth and advise whether it’s possible, or if frame replacement (or secondary glazing) is a better option.

What's the difference between standard clear (greenish) glass compared to low iron clear glass?

The difference comes down to iron content and how it affects the look and performance of the glass.

Standard clear glass has a green tint and slightly less clarity.
Low-iron glass is crystal clear, brighter, and shows true colors, but it’s more expensive.

Is imported toughened glass from Asia the same quality as Australian Toughened Glass?

The short answer: not necessarily.

Toughened (tempered) glass is made using a heat-treatment process that strengthens ordinary float glass so that, when broken, it shatters into small blunt fragments rather than sharp shards. The process itself is well-understood worldwide, but the quality and safety depend heavily on manufacturing standards and quality control.

Imported toughened glass can be the same quality as Australian glass if it’s from a reputable supplier and certified to AS/NZS 2208. Without that certification, you’re taking a compliance and safety risk.

Will I receive a compliance certificate once my glass is installed?

In Victoria glass installation—especially for windows, doors, balustrades, and safety glass—must comply with Australian Standards. You will receive one once I finish the work

Whats better to stop home intruders, toughened glass or laminated glass?

For burglary resistance, laminated glass is the superior choice. For shower screens, table tops and splashbacks toughened glass should be used

Does a qualified glazier need to be used for glass installation?

While not every piece of glass legally requires a qualified glazier, in most cases where safety glass is required, or where the work forms part of regulated building work, using a qualified glazier is the safe (and often required) path.

In Victoria Can float glass be installed in doors or side lights?

No, you cannot install float glass in doors or sidelights (unless it’s very small and specifically outside the “human impact” zones, but in practice, safety glass is almost always required).

Whats better frameless or semi frameless shower screens?

Frameless works best in high-end renovations or when space needs to feel bigger.
Semi-frameless is great for family bathrooms or investment properties (budget-friendly, durable).

Can laminate glass be cut?

Yes, laminated glass can be cut, but it is much more difficult than cutting regular (annealed) glass.

Can float glass be cut?

Yes — float glass can be cut, but only while it is still in its annealed (non-tempered) state.

Can a hole be cut in float glass?

If your glass is annealed float glass, yes, a hole can be cut. If it’s already tempered, the only option is to replace it with a new piece that has the hole pre-cut.

Can obscured glass be installed in shower screens?

yes, obscured glass is compliant and often a practical option for shower screens

Are there regulations as to what glass can be installed on balustrades in victoria?

Yes, regulations apply. In Victoria, only safety glass (toughened or laminated safety glass, often laminated toughened for frameless) that meets AS 1288 and NCC requirements can legally be installed in balustrades.

Does applying treatments to prevent water marks, soap scum buildup to shower glass after the glass is installed really work?

Yes and No, Products like EnduroShield and Nano Clean work, but it’s important to understand what it actually does and what it doesn’t do.

On shower glass, it reduces water marks, soap scum buildup, and mineral staining. You’ll still need to clean, but it’s faster and less effort.
On outdoor glass (balustrades, pool fencing, windows), it helps repel dirt, salt, and grime, which can reduce corrosion and clouding.
On tiles & grout, it helps stop mould and grime sticking, making maintenance easier.

However

It won’t make glass “self-cleaning.” You still need to clean occasionally, but with less scrubbing.
The effectiveness depends on proper application (professional application tends to last longer than DIY kits).
The coating can wear down over time (typically marketed to last up to 10 years on professionally applied glass).

Why are glass splashbacks better than tile splashbacks?

The main trade-off is cost: glass splashbacks are typically more expensive upfront than tiles, but many people find the long-term ease of cleaning, durability, and sleek finish well worth it.

What types of glass can be used in glass splashbacks?

Always use toughened safety glass (standard, low-iron, mirrored, or printed) for splashbacks, especially behind stoves, to meet Australian safety standards.

Can you provide tips on cleaning glass?

Everyday Cleaning

Use a microfiber cloth – They don’t leave lint and give a streak-free finish.
Warm water + mild detergent – A drop of dishwashing liquid in a bucket of warm water works for most glass.
Wipe vertically then horizontally – This helps spot any missed areas and reduces streaking.

Stubborn Marks & Streaks

Vinegar solution – Mix equal parts white vinegar and water in a spray bottle for soap scum, fingerprints, or mineral spots.
Razor blade scraper (carefully) – For paint or stubborn grime on flat glass, always keep the blade at a shallow angle to avoid scratching.
Bicarbonate of soda paste – Useful for removing stuck-on grime when applied gently with a damp cloth.

Avoiding Problems

Don’t clean in direct sunlight – The glass dries too quickly and leaves streaks.
Avoid paper towels & newspaper – They can leave lint, streaks, or ink smudges.
Skip harsh chemicals – Strong cleaners like bleach or abrasive powders can damage coatings or tint.

What are my decorative glass options?

The length of time required for an expert job completion depends on the type of glass, size, and location. An accessible aluminium window, for instance, will usually take about 45 minutes to complete a glass replacement whereas a frameless shower screen can take 2-3 hours.

Are there certain types of glass that can protect my property?

Yes. We can install safety or security glass into specific windows in your property to increase your personal safety and add protection to your assets. This type of glass has an improved resistance to impact or penetration and forced entry. We recommend Laminated Glass over Toughened Glass because Laminated Glass once cracked will stay together and is incredibly difficult to penetrate whereas Toughened Glass once it has exploded will allow direct access into the area.

Why can't you use the existing glass for the pet door?

For the safety of your pets and for durability, we only use toughened glass. Toughened glass has to be cut to size to suit your requirements, including the hole where the pet door will be installed. Toughened glass is also more durable to withstand the constant flexing and knocking it will endure as a result of your pet going in and out of the door.
