Many countries are committed to reducing energy consumption. Windows have been targeted as a major energy reduction opportunity in residential and commercial buildings. Evidence shows that the total amount of thermal emissions can be reduced if double glazed windows are used. Double glazed units are considered to become a major trend for years to come.
National Glass manufactures Double Glazed Glass units using flexible spacer bars and promotes “Warm Edge Technology”, which contributes to energy efficient buildings.
The flexible spacer follows the edge of the glass and is a complete insulating glass spacer system which requires only one start and finish joint. It does not allow heat loss transmission through the spacer bar.
Double Glazed Units are manufactured from two or more panes of glass held apart by a spacer and bonded with a hermetic seal, trapping dehydrated air between the glass panes. Their primary function is to improve the thermal insulating properties of window glazing, as well as contribute to safety, security and acoustics. The appearance and performance of Double Glazed Units can be modified by incorporating different glass types and thicknesses, altering the width of the spacer bar or gas filling the cavity space.
The benefits and functions of Insulated Glass include:
- Controlling heat and cold transfer through windows
- The reduction of sound transmission
- Increased wind loading resistance
- Minimizing the formation of condensation on glass
- Increasing safety and security
