SILVERGLASS 70 — Next-generation solar control glass
🌟 Cooler in summer. Warmer in winter. Still plenty of light.
What is SILVERGLASS 70?
SILVERGLASS 70 is an advanced double-glazed unit with a solar control coating that changes how solar radiation affects your interior.
The coating is applied using a magnetron process — the same technology used in the best low-emissivity glass coatings. The difference is that SILVERGLASS 70 is specifically designed for hot climates, where summer protection against overheating is essential.
How it works
- ☀️Light rays (what you see) — pass through the glass, giving you a natural, bright interior.
- 🌡️Heat rays (what you feel as heat) — are reflected back outside.
Think of it as sunscreen for your home — except it works 24/7, 365 days a year, with no moving parts or maintenance.
The technology inside every SILVERGLASS 70 unit
SILVERGLASS 70 is not a film or a tint — it is a full insulated glass unit built for the Australian and New Zealand sun.
Magnetron-sputtered silver coating
Ultra-thin silver layers applied under vacuum reflect infrared heat while staying optically neutral — the same class of coating used in premium European low-E glass.
Warm-edge spacer
Insulated spacer around the glass edge eliminates the cold bridge and reduces condensation, keeping the Ug value low year-round.
Argon gas fill
The cavity between panes is filled with argon, a denser inert gas that slows heat transfer far better than plain air.
Toughened / laminated options
Available as toughened or laminated safety glass for large openings, doors and floor-level glazing — meeting Australian AS 1288 requirements.
What it means for you in practice
| Parameter | Value | What it means |
|---|---|---|
| Light transmittance | 70% | Interior stays bright and pleasant — you don't lose natural light. |
| Heat transmittance (g-value) | 37% | 63% of solar heat energy stays outside — doesn't heat up your home. |
| Thermal insulation (Ug) | 1.0 W/m²K | In winter, heat from your heating doesn't escape through the glass. |
| External reflection | 13% | Delicate, neutral blue tint — elegant and modern appearance. |
Does SILVERGLASS 70 help save on air conditioning and heating?
Yes, and significantly. Compared to standard glass, our glazing blocks approximately 60% more heat radiation from entering your home. This means in summer:
- ☀️ Less heat in your home — interior warms up more slowly, even on the hottest days.
- ❄️ Air conditioning works less and shorter — you use less electricity.
- 💰 Lower cooling bills — visible on every energy bill.
And what about winter?
- 🔥 Warmer home — less heat loss through windows.
- 💰 Lower heating bills — your heating system doesn't have to work as hard.
How much exactly will you save? It depends on window size, solar exposure, local climate and your habits. One thing is certain — SILVERGLASS 70 is an investment that pays for itself through lower bills and greater comfort all year round.
Glass alone or with blinds? You choose!
SILVERGLASS 70 is not a replacement for blinds or awnings — it's an additional layer of protection.
Use it on its own and you'll already feel a huge difference. The interior stays brighter and cooler, even when the sun is shining at full intensity. A great solution for people who don't want to cover their windows, but also don't want to live in a greenhouse.
Use it together with blinds or awnings and the effect is even better. Blinds stop some radiation before it reaches the glass, and SILVERGLASS 70 reflects what has already penetrated. Together they provide double protection — especially useful on the sunniest days.
Glass alone → reflects 63% of heat, lets in plenty of light.
Glass + blinds/awnings → maximum protection, comfort even in extreme heat.
You choose — both options are good. Together they are best.
Why is this solution ideal for the Australian and New Zealand market?
In Australia and New Zealand, summer can be relentless. Heatwaves are longer and more intense, and air conditioning is no longer a luxury — it's a necessity. But cooling your home costs more and more. SILVERGLASS 70 helps:
- Lower energy bills — less heat = AC works shorter and less.
- Increase living comfort — no overheating of rooms, even on the hottest days.
- Reduce CO₂ emissions — you use less electricity, better for the planet.
- Give you choice — use the glass alone, add blinds, or use both.
And in winter? The coating works both ways — it keeps heat inside, so you don't lose it through the glass. A solution for the whole year, not just summer.
Built for Australian and New Zealand climate zones
From Queensland heatwaves to Auckland's UV-intense summers and Melbourne's four-seasons-in-a-day, SILVERGLASS 70 protects across the whole region.
Sydney, Brisbane & the Gold Coast
Long, humid summers with intense sun. SILVERGLASS 70 slashes solar heat gain so air-conditioning runs less on west-facing rooms.
Melbourne & Adelaide
Hot dry summers and cold winters. Ug 1.0 W/m²K keeps heating in when temperatures drop, while blocking summer heatwaves.
Perth & Darwin
Extreme UV and record heat days. The silver coating reflects infrared while the neutral tint protects furniture, floors and artwork from fading.
Auckland, Wellington & Christchurch
High UV combined with damp winters. Warm-edge spacer and argon fill cut condensation and heat loss through glazing.
SILVERGLASS 70 vs standard double glazing — the honest comparison
How SILVERGLASS 70 stacks up against single-pane and standard double glazing in the Australian and New Zealand climate. Lower numbers for Ug and g-value are better — they mean less heat loss and less summer overheating.
| Feature | Single glazing | Standard double glazing | SILVERGLASS 70 |
|---|---|---|---|
| Thermal insulation (Ug W/m²K) | ~5.8 — poor | ~2.7 — average | 1.0 — excellent |
| Solar heat rejected | ~15% | ~25% | 63% — reflected back outside |
| Solar heat gain (g-value) | 0.85 — hot rooms | 0.75 | 0.37 — cool interior |
| Natural light let in | 90% | 80% | 70% — still bright & neutral |
| UV protection (furniture fading) | None | Basic | Strong — blocks IR + UV |
| Air-conditioning bills in AU/NZ summer | Very high | High | Meaningfully lower |
| Winter heat loss (Melbourne / NZ) | Severe | Moderate | Minimal — argon + warm-edge |
| Condensation on glass | Frequent | Occasional | Rare — warm-edge spacer |
| Safety (AS 1288 toughened/laminated) | Optional | Optional | Optional — same standards |
| Best orientation | None — always compromise | South-facing rooms | West, north & large glazed walls |
Only where budget rules — sheds, garages, non-habitable rooms.
General upgrade — works in mild climates and shaded rooms.
Sun-exposed AU/NZ homes, large glazing, west/north walls, top-floor rooms, coastal builds.

Is it complicated?
No. You simply choose SILVERGLASS 70 instead of regular glass. You don't have to give up blinds or awnings — quite the opposite. The window installs exactly the same, looks practically the same (a delicate blue tint in reflection), but works completely differently. One decision — and you get comfort all year round.
Who is SILVERGLASS 70 for?
- ✅For anyone building a home or replacing windows.
- ✅For residents of single-family homes, apartments and offices.
- ✅For those who want plenty of natural light, but not a greenhouse in summer.
- ✅For those who already have blinds or awnings and want to boost their effectiveness.
- ✅For those who don't want blinds and are looking for alternative heat protection.
SILVERGLASS 70 — frequently asked questions
Everything Australian and New Zealand homeowners ask before choosing solar control glass.
