Core technologies we offer
| Solution | How it works | Typical benefits |
|---|---|---|
| Low-E single glazing | A microscopically thin metallic coating reflects long-wave infrared heat while allowing visible light to pass | Reduces winter heat loss, improves insulation without adding weight |
| Insulated glass units (IGUs) | Two or more glass panes separated by a sealed air or argon space | Lowers U-value, cuts condensation, enhances acoustic performance |
| Solar control glass | Tinted or spectrally selective coatings block a portion of solar radiation | Limits summer heat gain, reduces glare, helps meet Section J solar heat gain requirements |
| Low-E IGUs | Low-E coating on one surface within a double-glazed unit | Combines winter insulation with summer solar rejection for year-round efficiency |
All products use Grade A safety glass compliant with AS/NZS 2208. Spacer bars feature integrated desiccant to prevent moisture build-up and long-life primary and secondary seals maintain gas fill integrity over time.
Residential benefits
- Thermal comfort - Steadier indoor temperatures mean fewer draughts and cold spots
- Lower energy bills - Reduced HVAC cycling translates into measurable savings over the life of the building
- Condensation control - Warmer interior glass surfaces minimise fogging that can damage frames and finishes
- Acoustic improvement - The airspace in an IGU dampens outside noise, supporting quieter bedrooms and studies
- Sun protection - Solar control coatings limit UV ingress, helping protect furnishings from fading
Commercial advantages
- Compliance support - Performance data helps project teams satisfy Section J envelope modelling and Green Star points
- Increased tenant appeal - Comfortable interiors attract quality occupants and reduce churn
- Operational savings - Lower peak cooling loads can defer plant upgrades and shrink ongoing power costs
- Glare management - Tinted or spectrally selective glass cuts glare on monitors, boosting productivity in offices
- Sustainability credentials - Better thermal metrics contribute to NABERS and Green Star ratings, enhancing asset value
Our five-step pathway to better performance
- Discovery and audit - We review architectural drawings, facade orientation and local climate data, then outline suitable glazing options and baseline thermal metrics.
- Specification and modelling - Performance reports detail U-value, solar heat gain coefficient (SHGC) and visible light transmittance so designers can balance efficiency targets with daylight and aesthetics.
- Measure and procure - Accurate site measurements guide fabrication. IGUs and coated glass are produced by accredited Australian manufacturers using argon gas fills and warm-edge spacers where required.
- Installation and sealing - Qualified glaziers fit units with back-bedding sealant, setting blocks and approved glazing tapes, ensuring continuous air-water seals to AS 1288.
- Verification and handover - We supply product data sheets, gas fill certification and maintenance guidelines for inclusion in the building manual.
Maintenance essentials
Energy efficient glazing needs only standard care. Wash with a soft cloth, warm water and mild detergent, rinse well and squeegee dry. Avoid abrasive pads or alkaline cleaners that may damage low-E coatings at exposed edges. Inspect perimeter seals annually, particularly in coastal locations where salt can accelerate sealant degradation. If you notice condensation between panes, arrange an inspection promptly, as this suggests a loss of unit integrity.
Frequently asked questions
- Will low-E glass look mirrored from outside?
Low-E coatings used today are largely neutral. There may be a subtle tint under certain angles or lighting, but most installations appear clear.
- Does double glazing suit heritage windows?
Yes. Slim-profile IGUs and specialised beading allow performance upgrades without altering sightlines on character homes. Heritage approvals vary by council, so we recommend confirming local requirements early.
- Is argon gas worth the extra cost?
Argon's lower thermal conductivity further reduces heat transfer compared with air. The uplift is modest but can help projects achieve strict energy thresholds at minimal added expense.
- Can I retrofit energy efficient glass into existing aluminium frames?
In many cases yes. We assess frame depth, glazing pocket size and hardware condition to confirm suitability, then fabricate IGUs to fit. Some older frames may require adaptors or full replacement.
- How long do IGUs last?
Service life depends on manufacturing quality, correct installation and exposure conditions. Industry data suggests well-made units routinely exceed twenty years without loss of performance.
- Will energy efficient glass reduce fading of fabrics?
Low-E and solar control coatings block a significant proportion of UV radiation, slowing colour fade. No glazing can stop fading entirely, yet treated glass offers better protection than clear float.
