Renovations of older Sydney homes (built pre-2000) where budget is a primary constraint.
Non-living spaces like storage rooms, garages, or utility areas with minimal comfort requirements.
Temporary structures or low-cost rental properties where long-term energy efficiency isn’t a priority.
A double glazed window consists of two glass panes separated by a sealed air or argon gas layer (usually 6-20mm thick), mounted in a high-quality aluminum frame (often with thermal breaks for better performance). For Sydney's high-end projects, it's often paired with Low-E (low-emissivity) coatings to enhance UV and heat resistance.
New-build high-end villas, luxury apartments, or boutique renovations in Sydney’s eastern suburbs (Bondi, Vaucluse) or northern beaches.
Living rooms, bedrooms, and kitchens—spaces where comfort, noise reduction, and energy efficiency are critical.
Coastal homes exposed to salt spray (e.g., Manly, Cronulla) or urban properties near busy roads (e.g., CBD, Parramatta) needing noise insulation.
| Factor | Single Glazed Window | Double Glazed Window |
| Thermal Insulation | Poor. Single pane conducts heat easily—summer sun bakes interiors, winter heat escapes fast. Leads to 30-40% higher AC/heating bills. | Excellent. Sealed gas layer blocks heat transfer. Reduces cooling needs by 20-30% (critical for Sydney’s 30°C+ summers) and retains warmth in mild winters. |
| Noise Reduction | Minimal. Blocks only 20-25dB of noise—insufficient for Sydney’s traffic, airport, or coastal wind noise. | Superior. Reduces noise by 35-45dB—muffles traffic, neighbor chatter, or storm winds, ideal for urban/coastal homes. |
| UV Protection | Weak. Lets 80%+ of UV rays pass through—fades furniture, carpets, and artwork quickly under Sydney’s intense sun. | Strong. Low-E coated double glazing blocks 99% of UV rays, preserving luxury interiors (e.g., designer sofas, wooden floors) for years. |
| Weather Resistance | Basic. Poor sealing leads to water leakage during Sydney’s heavy rains; single pane is prone to condensation. | Excellent. Multi-layer sealing prevents rain infiltration; argon gas layer reduces condensation. Aluminum frames (e.g., Rolandini’s 6063-T5 aluminum) resist salt corrosion for coastal homes. |
| Compliance & Value | Fails modern standards. Doesn’t meet Sydney’s AS2047 energy/weather requirements for new builds; adds little to property value. | Fully compliant. Meets AS2047 (tested for wind load, water resistance) and boosts home value by 5-10%—a key plus for high-end Sydney properties. |
| Cost | Low upfront cost ($80-$150 per sqm). But higher long-term energy and replacement costs. | Higher upfront cost ($200-$350 per sqm). But saves $300-$500 yearly on energy bills; lasts 20+ years (vs. 10-12 years for single glazed). |
