• Insulated Glazed Units

  Double or triple insulated glazed units (IGUs) are installed in new builds or as replacement glazing due to their thermal efficient characteristics. Multi-pane IGUs are made using different pane thicknesses, contain a range of cavity depths, and may have the cavity filled with an inert gas, all depending on the window specifications and performance requirements.

• Special Coatings

  ​IGUs can be treated with different coatings for different results. The use of coatings applied to the inner surface of a glass pane, can improve various properties. Solar control windows for example, can reduce the UV rays entering through the glazing to help keep your carpet, floors and pictures from fading in rooms that get the most light.

• Ratings Window Energy Ratings tell you how energy-efficient your windows are. The rating system is based on a scale of A-G, with A-rated windows being the most energy-efficient.

  Remember Every single window size and configuration will have its own separate and unique rating, your Accredited Vista Therm dealer will be able to give you a range where their windows fall or the ratings for a sample window.

Some of the technical aspects of glazing explained.

• U-Value

  The U-value describes how well a building element conducts heat. The lower the value, the better an insulator a material is.

• Elite Low-E Coating

  Elite Low-E glass features a special coating on the window pane that reduces heat transfer, preventing heat from entering a home in warm climates or from leaving a home in cooler climates. Windows that feature Elite Low-E coatings are far more efficient at reducing heat loss than non-coated windows.

• Gas-Filled Windows

  Both noise reduction and thermal insulation can be greatly improved by filling the cavities between the glass panes with a low conductance gas like argon or krypton. These gasses also offer significantly better thermal resistance than air, resulting in greater insulation and hugely improved energy efficiency
