Low E Glass

Why use Low E Glass?

Low Emissivity (low E) 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.

Benefits

  • Significantly reduces heating loss compared with Double Glazed Windows without Low E Glass
  • Aligned with the NZ Building Code – improves the minimum energy performance standard of windows
  • Reduces the heating and cooling costs of your home
  • Less condensation – Low E Glass keeps the internal pane of glass warmer therefore reducing the occurrence of condensation
  • Improved comfort – your home is warmer in the winter and cooler in the summer
  • Healthier home - reduced condensation, improved warmth and a drier home
  • Reduces fading of fabrics, carpet, and furniture caused by the sun’s UV light
  • Provides remarkable clarity - the Low E coating does not affect clarity, so you can enjoy the view.

 

Stake Glass is now the Stockist of Low E ADVANCED 1.1  

A Low E double glazed window will give you a U Value of 1.1, when it is combined with a 14mm Thermal Spacer and Argon Gas.    The U Value measures the difference between the indoor and outdoor temperatures, or how much heat passes through your glass.  A lower U-value means lower heat transfer and better insulation of your home.

Therefore, Low E Advanced 1.1 will give you even greater insulating/performance, air gap properties than our Low E Planitherm 1.3.

 

Thermal Insulation (Argon Gas)

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.
