Energy Efficient glass for Windows and Doors
Energy-efficient glazing is a term used to describe the glass in windows and doors specifically engineered to reduce heat transfer and improve the overall energy efficiency of the building. Double glazing and triple glazing is used in modern homes as your energy efficient glazing solutions.
The glass and frames in your windows and doors can have a significant effect on the thermal performance of your home or business. It's estimated that up to 40% of a home's heat can be lost as well as 87% of its heat gained through your windows and doors.
Simply put, energy efficient glazing is when your windows and doors are glazed using double glazed or triple glazed glass. This is where 2 or more layers of glass are sealed into the window/door frame with a gap between each layer acting as insulation.
The most energy-efficient glass used is a low-emissivity glass (Low-E Glass), which is a specialised type of glass layered with an invisible coating to substantially reduce heat transfer.
Energy-efficient glazing keeps your home warm in winter and cool in summer making for a more comfortable home. This lowers costs in energy bills and greenhouse gas emissions.
Some benefits of energy efficient glazing include:
- Better insulation
- Lower energy costs
- Noise reduction
- Protection from internal sun damage to furniture and flooring
- A more comfortable home
- Less condensation on windows
Energy Performance of energy-efficient glass
Double glazed and triple glazed windows (also known as insulated glass units or IGUs) offer much better energy-efficiency than single glazed glass, simply because they transfer far less energy.
NOTE: SHGC means Solar Heat Gain Co-Efficient, and refers to the measurement of solar heat transfer through the glass. VLT means Visible Light Transmittance and refers to the amount of light that passes through the glass (low VLT can reduce heat gain but also darkens the room).
The performance of your glass still depends on several other factors on top of this:
- The glass types used on each layer of glass. With double and triple glazing, different types of glass can be put together in the different layers of the IGU. You could have one layer as clear glass and the other as low-e glass. Different combinations such as this can deliver a wide range of SHGC and VLT values to suit specific performance needs.
- The air contents between the layers of glass. IGU cavities can be filled with air or low conductive gas such as argon gas.
- The width of the contents between each layer of glass. The thickness of this cavity is usually anywhere from 6mm to 188mm, with wider cavities providing better energy performance.
- The quality of the sealant used and the installation to seal the glass layers. These layers must be very well sealed to prevent moisture from getting in. Ensuring your windows and doors are sealed with good quality sealers will lead to a much more energy-efficient window or door.
