Double or triple glazing in contemporaryhome windows is known as energy efficient window glazing.It is unlike the single glazing or original double glazing as it combines low emissivity coated glass to stop heat from escaping through. This ensures that the window is thermally insulating and improves the energy efficiency in your home.
What is low emissivity glass?
Commonly called low e glass is an energy efficient glass that ensures heat and cold do not pass through. It has a coating that is invisible which reduces heat transfer and keeps inside heat, inside. The older double pane windows do not contain low e glass and thus are not energy efficient. If you replace your existing glass with low e glass, you will significantly improve energy efficiency in your home and thus decrease utility bills. It is important to have low e glass in rooms or buildings with lots of windows or glass doors. This glass type retains heat even in colder months and rooms where overheating is a problem.
What are the benefits of energy efficient glazing?
- Improves the energy efficiency in your home thus reducing the amount of energy that you use
- Saves you money on heating bills
- Available from a host of window installers countrywide
- More effective than single and standarddouble glazing
Where should energy saving glass be used?
It can be used anywhere in your home where extra heat is retained, or rooms that tend to become very cold in winter. Places that would benefit from energy saving glass include:
- Windows
- Doors
- Conservatories
- Rooflights
Energy saving glass can be used with other variations of glass to give you the benefits you want, such as decorative, safety and noise reduction.
Research shows that approximately 40% of a house’s heat can be lost through windows and about 87% of its heat can be gained through them as well.
What are the different types of energy efficient windows?
Glass windows: There are many different products available for glass windows. Thickness of the glass has an impact on the safety and strength of the glazing but little effect on the amount of heat that escapes through it.
Double glazing windows: This type includes two layers of glass with a space between them the space acts as an insulation which helps with heat reduction and retention.
Gas filled windows: this type has gas filled spaces that also help with insulation. It is a new type of window which uses argon, krypton or xenon. These gases have low conductivity and helps keep heat inside and helps with noise reduction reducing noise pollution.
Energy efficiency is a great benefit to those wanting to enjoy their home and make it comfortable. Low e 4th surface technology helps with the thermal performance of double-glazed insulated glass units.
Ongoing improvements are being made to the frames, glass and gas combination and this will increase the consumers choice of energy efficient windows.
