Smart Sustainable Living

Energy efficient homes lead to lower bills, more comfort and ultimately improve property values.

Energy Efficiency

Many factors influence the energy efficiency of a home. Windows and doors are one of the main ways of achieving a higher energy efficiency rating.

Energy efficiency involves achieving something with the least amount of energy usage possible. With windows, energy efficiency involves maintaining your ideal home temperature for less money.

The higher the energy efficiency rating of your windows and doors, the better. The insulation will be better. And they will be better at trapping in the air from heating and cooling systems. This leads to less money spent on heating and cooling your house!

You can lose 45% of a home’s heating energy through windows and doors. And you can also gain 85% of a home’s heat through its doors and windows.

Designing for climate

Energy efficiency

Energy Efficient building design considers the specific climatic conditions of a given site. Energy efficiency involves achieving something with the least amount of energy usage possible.

Windows

Energy-efficient windows should maximise the heating and cooling conditions in your home. This also includes minimising energy expenditure.

Passive Design

Good passive design ensures everyone remains thermal and comfortable. This includes minimal auxiliary heating or cooling.

Australian homes and buildings amount to nearly a quarter of our greenhouse gas emissions.

Insulation

  • Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer.
  • Double glazing is the most cost-effective way to minimise heat transfer through windows and glazed doors and can be even more effective when they feature high performing glass within the insulated glass unit (IGU).
  • Double Glazed Units (or DGUs) are window units made of many glass panels. Sealed with a spacer and gas between them, Thermotek uses an inert gas, argon. This is for greater thermal performance.
  • Climatic conditions influence the appropriate level and type of insulation. There are over eight climate zones defined by the National Construction Code (NCC). Establish whether the insulation is more about keeping heat out or in (or both).
  • Thermotek glues the window sashes to the pane. This increases the window’s impermeability, thermal insulation, and enhancing their stability. Bonding inside, windows no longer need to reinforcing with steel profiles. Being steel free eliminates its unfavourable thermal properties from our products.

Heat gain and loss in the Australian climate

Wherever you live in Australia, your windows and doors can play a big role in your houses efficiency.

Windows and doors let in light and fresh air, however, they can be a major source of unwanted heat gain.

Glazing

Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer. One of the most effective additions to a home’s insulation is good double glazing. Our double glazed windows are the most cost-effective way to minimise heat transfer.

Frame

Sash design technology also improves your windows and door energy efficiency. For controlled airflow, we glue our window sashes to the pane. This increases the window’s water resistance, thermal insulation, and stability. You can lose or gain heat through windows and glazed doors as air moves through gaps. You can minimise this by installing good seals. But ventilation is also important to keep dampness out!

Ventilation & Insulation

Thermotek products hit the perfect balance between ventilation and insulation. They feature two seals on every opening element. As well as ventilation systems at the top of your window, between the frame and sash. They create a permanent yet controlled flow of air so that you don’t have to do it yourself. These simple, very effective systems create a pleasant atmosphere in a dwelling.

Improved Performace and Efficiency

Our wide range of glass products can help any building improve its energy efficiency.

Cooler climates:
Low E Glass – can prevent up to 39% of heat loss.
Double Glazing – can prevent up to 55% of heat loss.
Double Glazing with Low E Glass – can prevent up to 70% of heat loss.*

Warmer climates:
Low E Glass – can prevent up to 40% of solar heat gain.
Tinted Low E Glass – can prevent up to 57% of solar heat gain.
Double Glazing with Low E Glass – can prevent up to 77% of solar heat gain.

Data has been calculated using NFRC 100 – 2001 environmental conditions and Window 5.2 software from the Lawrence Berkeley National Laboratory (2006). Results may vary depending on actual operating conditions. Savings are in comparison to using 3 mm clear glass.
