Energy Efficient Windows

Mostly window and doors manufacturers offer many types of window glazing work. All windows should be double-glazed or triple glazed. If you face difficulty in determining the type of glazing of your windows, contact us at London Glazing. Insulation values of the glazing windows are measured in R (imperial) and RSI (metric), the higher the value of the window, the better will be insulating material.

Standard Triple Glazing
Triple glazing adds the insulation value of a glass unit by adding extra space between its panels. The only way to make sealed glass thermal resistant is to upgrade your triple glazing. Now several technologies offer better performance of the glazing windows. Triple glazing has been greatly replaced standard double-glazing. Extra triple glazing provides extra high performance using Low-E glazing and gas filling.

Glass Coatings
Low-emissivity coatings increase the value of glazing windows by reducing heat loss. They reflect blazing heat vented by room. These coatings of Low-emissivity are almost invisible and a coated unit has about the insulation value as an uncoated glazed unit. Glass with Low-E coating is labeled as Low-E2.

Gas Fill
The insulation value of a glazing window is greater inert gas like krypton or argon is used to fill the volume between the glass panes. Argon gas is inexpensive than krypton gas that is why it is mostly used in gas filling.

Improved Seals Edge
Aluminum edges conduct heat speedily and can significantly lessen the window’s protection value. Aluminum non-conductive spacers help to reduce heat loss and provide potential for condensation.

Choosing the Right Glazing
It may be difficult task to decide which type of glazing work is good for efficiency and comfort.
