What is Double Glazing?

A Double Glazed Window is made from two panes of glass separated by a layer of air or gas.

Also known as an Insulating Glass Unit (IGU) they can be made from two different types of glass depending on the specific requirements of your home. Single glazed windows are the most significant source of heat loss in a home. The more glass surface area you have, the more heat you stand to lose. In a well-insulated home, approximately 60% of heat is lost through single-glazed windows.

However, heat loss through single glazed windows can be halved using double glazing. In a double glazed window the gap between the two panes of glass is filled with air. Air is a poor conductor of heat, so heat loss is reduced.

                                            

Double glazing a window can halve the heat loss compared with a single glazed window. You can reduce heat loss further by using different glass types (such as Low Emissivity (Low E) Glass) or by choosing units which use Argon Gas instead of Air to fill the space between the two panes of glass.

Since 2007, double glazing in NZ has been specified by building standards as a requirement for new homes. When double glazing is combined with ceiling, wall and floor insulation you will reduce your energy use, save money on your energy bills and improve the comfort of your home. The overall result for you and your family is a healthier home.

Benefits of Double Glazing

  • A cosy, comfortable home all year round - warmer in winter and comfortably cool in summer
  • Healthier home with less condensation - warmer houses have drier windows and a drier home is much healthier
  • Double Glazing helps noise reduction, creating a shield against external noises,  giving you quieter nights
  • Lower energy bills - double glazing offers superior energy efficiency
  • Increased security - double glazed windows are much harder to break
  • Reduces draughts - well insulated, warm homes aren’t draughty
  • Adds value to your property - indicates to potential buyers that the house is well insulated, warm and cared for
  • Reduces fading of furniture and furnishings - minimises the impact of the sun’s harsh ultraviolet rayset 

 


Thermal Insulation

(Argon Gas, Warm Edge, Altitude Glazing)

Boost the insulation benefits of double glazing by combining argon gas and Low E glass. This will create high performance double glazing.

What is Argon Gas?

Argon gas is a naturally occurring, non-harmful gas. When argon gas is inserted between the panes of glass it increases the insulating performance of your double glazing. Argon gas is denser than air, so adding it to the air between the two panes improves thermal insulation efficiency. When a glazing unit features Low E glass and Argon Gas it brings the temperature of the window closer to room temperature. This combination eliminates air currents and drafts that occur when differing temperatures meet.

What is Warm Edge?

A warm edge spacer is a type of spacer bar used in insulated glazing. It separates the panes of glass in double or triple glazing, or curtain walling and seals off the air cavity between each. Recent warm edge spacers are generally made from plastics, although stainless steel can meet the definition.

Warm edge spacer bars become a barrier for heat loss, reducing the amount of heat your home loses.

Traditionally, spacer bars were aluminium, which is highly conductive to heat, allowing it to pass through the window. By installing units with a warm edge spacer bar, their goal is to keep the edge of the sealed unit warm.

What is Altitude Glazing?

Insulating high-altitude glass uses a capillary system which allows the glass pressure to equalize at higher elevations and maintain a flat appearance over time.

Double Glazed Low E Glass 

Why use Low E Glass (Low Emissivity Glass)?

Windows can reflect, take in, and transfer heat, so Low E coatings can be used to enhance the performance of a window.

Low E is a common abbreviation of “Low Emissivity”. Low Emissivity means a surface that gives off low levels of radiant heat. Therefore, a glass window with a Low E coating will reduce the amount of heat transfer, making your house warmer in the winter and cooler in the summer.

This clear coating is thin —even thinner than a human hair—so it cannot be seen.  A Low E coating increases thermal performance by reducing ultraviolet and infrared light coming through the glass window, but it doesn't compromise the amount of visible light that is transferred.

Low E coatings reflect radiant heat - either from outside or inside, therefore reducing the heating and cooling costs of your home.

Double Glazing a window can halve the heat loss compared with a single glazed window. You can reduce heat loss further by using Low E Glass or by choosing units which use Argon Gas instead of Air to fill the space between the two panes of glass.

 


Triple Glazing

Three Panes of Glass

Triple glazing takes window insulation one step further.  A Triple Glazing Unit comprises of three panes of glass separated by air gaps.  Triple glazing provides the highest levels of heat retention and noise reduction.

Triple glazing is a great option to further enhance thermal performance.  It is also available for certain architectural designed window frame systems.
