Energy-efficient windows Adelaide
Comfort in summer, warmth in winter and lower bills
Energy efficient window solutions
Energy-efficient windows help Adelaide homes stay cool on hot days and hold warmth on cold nights. Double glazing pairs two panes with a sealed gap that slows heat flow, while insulated uPVC frames reduce transfer around the glass. Add a solar control option such as Coolite from Chevron Glass, and you cut unwanted heat from the afternoon sun without losing natural light. The result is a home that feels more comfortable across the seasons with less strain on your air conditioning and heating.

Why energy efficiency matters in Adelaide
Adelaide summers are hot and often dry, with long afternoons of high sun on west and north-facing windows. Winters bring cool mornings and evenings, where heat loss can make living areas feel flat and uncomfortable. As power prices continue to rise this makes every kilowatt saved valuable. Upgrading windows is one of the most effective ways to reduce heat gain and heat loss because windows are large openings compared to insulated walls and ceilings. Better performing windows support a steadier indoor temperature and reduce run time for air conditioning and heating, which lowers bills and improves comfort.
How energy-efficient windows work
An energy-efficient window is a complete system. The glass, the sealed gap and the frame each play a role, and the benefit comes from how they work together.
Double glazing for insulation
A double-glazed unit uses two panes of glass with a sealed gap between them. The gap is filled with argon gas to slow heat transfer, and the edges are sealed to keep moisture out. The edges are sealed to keep moisture out and maintain performance over time. This insulated glass unit reduces heat loss on cold nights and cuts heat gain on hot days compared to single glass.

uPVC frames for low conductivity
uPVC frames have low thermal conductivity, which means they do not pass heat quickly. Modern uPVC profiles use internal chambers that act like tiny insulating pockets. This structure reduces heat transfer around the glass and helps maintain an even temperature near the frame. Quality seals and hardware keep the frame airtight and watertight under wind and rain, which supports both energy and comfort goals.
Solar control glass for harsh sun
Solar control glass, such as Coolite, uses advanced coatings that reflect a portion of the sun’s energy while still allowing good daylight. This reduces solar heat gain in summer and limits glare in rooms that face west and north. When combined with double glazing and uPVC frames, solar control glass delivers a clear step up in summer comfort without making rooms feel dark.
Performance benefits you will notice
Lower u values for better insulation
U value is a measure of how much heat flows through a window. Lower numbers indicate better insulation. Double-glazed units with uPVC frames typically achieve much lower U values than single-glazed units with metal frames. This translates to a home that feels warmer in winter and cooler in summer with less energy use to hold a steady temperature.
Controlled solar heat gain for hot afternoons
Solar heat gain coefficient indicates how much solar energy passes through the glass. A lower number means less heat enters from sunlight. Solar control options such as Coolite reduce this value on exposed elevations, which helps keep living rooms and bedrooms comfortable during late afternoon and early evening when the sun is strongest.
Protection from ultraviolet
Ultraviolet light contributes to the fading of flooring, furniture and window coverings. Many modern coatings block a high percentage of ultraviolet while maintaining clear views. This helps protect finishes and soft furnishings and contributes to long-term value inside the home.
Reduced drafts and hot spots
Better sealing and insulated frames reduce cold drafts and local hot spots near windows. This helps living areas feel more even in temperature, so you use less energy to stay comfortable. Many homeowners notice that they sit closer to windows in winter after the upgrade because the cold edge effect is reduced.
Quieter rooms as a bonus
Energy upgrades often bring acoustic benefits. The insulated gap in double glazing and the tight sealing of uPVC frames reduce sound transmission. While this page focuses on energy, most installations also feel quieter, which is a welcome side effect in busy streets. If noise is a concern on the street, read more about noise reducing windows.
Our technology partners and product choices
Adelaide Double Glazing builds window systems on profile platforms from Kömmerling. These uPVC profiles use multi-chamber designs for thermal efficiency and accept steel or advanced composite reinforcements for strength where needed. The compounds use calcium zinc stabilisers rather than lead and are engineered for long service life in Australian sunlight.
We partner with Chevron Glass for insulated glass units and solar control products. The Coolite range provides solar control options suited to Adelaide’s hot summers while maintaining daylight and clear views. Pairing Coolite with low-emissivity coatings in a double-glazed unit can deliver strong summer performance while still improving winter retention, which is ideal for family homes and renovations.
Design that keeps light while managing heat
Many homeowners worry that energy-saving glass will make rooms feel dim. Modern solar control coatings are designed to balance light and heat. With the right product choice, you can keep a bright look and reduce the heat that makes rooms uncomfortable. West-facing living rooms can feel usable again in late afternoon, and bedrooms can stay cooler into the evening without heavy blinds drawn all day. Precise specifications are available that keep a neutral appearance from inside and outside, which suits contemporary homes across Adelaide.
Options for different orientations and rooms
A one-size approach rarely delivers the best result. Different sides of a home face different conditions, so it makes sense to select glass and frame options to match.
North and west-facing rooms
Solar control glass limits afternoon heat while keeping winter sun useful.
South-facing rooms
Low-emissivity double glazing improves winter retention without reducing the already soft light.
Bedrooms
Insulated units with strong sealing help hold a steady temperature overnight and can be combined with acoustic interlayers if needed. For bedrooms near traffic or flight paths consider noise reduction windows.
Kitchens and living areas
Solar control with easy clean options can suit high-use spaces where comfort and clarity matter.
Bathrooms
Safety glass and privacy options are available with the same energy performance as clear glass.
uPVC windows versus aluminium for energy efficiency
Aluminium conducts heat readily, which is why many aluminium frames require a separate thermal break to improve performance. uPVC is an insulating material by nature. The whole profile contributes to thermal control, not just an insert. With multi-chamber profiles and accurate seals, uPVC frames help the complete window achieve lower U values and tighter air leakage numbers. In the home, this shows up as reduced heating and cooling use to maintain comfort and a more consistent feel across different zones.
Compliance and building standards
New homes and major renovations in Australia are working to higher energy performance targets under the National Construction Code. Better windows help achieve these outcomes by reducing heating and cooling loads. While compliance is assessed at the whole building level, the performance of windows is a key input. We supply performance data for window and glass combinations and can work with your builder or energy assessor to align product selection with your energy rating goals.

Styles that work with energy glass
Energy performance does not limit design choice. uPVC systems support a full range of operating types that seal tightly when closed.
Casement windows
Casement windows hinge from the side, capture breezes and close with continuous seals. They suit living rooms and bedrooms where strong sealing and ventilation are both helpful.
Tilt and turn windows
Tilt and turn windows offer secure ventilation and easy cleaning from inside. The locking system pulls the sash evenly onto seals, which supports energy performance.
Sliding windows
Modern uPVC sliders use engineered tracks and multiple seals to control air leakage. They are practical near decks and walkways where outward-opening sashes are not ideal.
Fixed picture windows
Fixed panes provide maximum insulation and daylight where ventilation is not needed. Combine with opening sashes nearby to manage airflow.
Colours and finishes for a neat result
Choose classic white for a clean look or select contemporary colours to match your facade. Woodgrain foils provide the warmth of timber without a painting cycle. You can choose one colour outside with white inside or match both sides for a consistent appearance. All finishes are designed for long-term exposure in Australian sunlight.
Sustainability and lifecycle benefits
Energy-efficient windows reduce heating and cooling demand, which lowers household emissions. uPVC frames use stabilisers that avoid lead, and many manufacturers operate recycling programs for post-production scrap and old frames. The long service life of uPVC supports a lower lifecycle footprint compared to products that need regular repainting or that conduct heat more readily. Selecting better windows contributes to a more comfortable home and to broader sustainability goals.
Installation quality that protects performance
Correct installation is essential to achieve the expected energy gains. Frames must be plumb and square, so seals meet evenly. Perimeter joints must be sealed to the building envelope to prevent air leakage. Sill and flashing details must manage water so that wind-driven rain does not enter at interfaces. Hardware must be adjusted so that locks compress seals without strain. Adelaide Double Glazing follows these steps as standard, so the installed window performs like the one that was specified.
