Glazing

Glass is one of the largest external materials used in a new home and normal “float” glass is not a very good insulator. It allows heat and cold to transfer through it quite easily. As a result, a lot of heat and cold escapes from the home through glass windows. This is a waste of energy if the air inside the home has been artificially heated or cooled.

Upgrading the glass of the home will minimise the transfer of heat and UV light from the home outside and the reverse in Winter time. The upgrades are often needed to ensure compliance with the energy efficiency measures of the BCA.

Upgrades available include

Tinted glass (Comfortone) – stops the UV light from penetrating the windows and helps to keep the house cooler in summer time.

Low E glass (Sunergy or Comfortplus) – glass made using a different process which has far greater thermal insulation properties and UV light stopping features than standard tinted glass.

Double Glazed windows – two panels of glass with a sealed air space between them. This air spaces acts as a barrier which separates the two panes of glass and limits the transfer of heat and sound through the window.

Note: This upgrade of glass can be used in specific windows in the home (that may face West or East) and does not have to be used throughout the entire home to be effective.
