High Performance Double Glazing.

In Australia, but more so the state of Victoria we are subject to extreme summers and rather cold winters, leaving us wondering how do we keep internal temperatures optimal year-round?

Our DGU Premium range offers a perfect balance of insulating properties and solar control ability, making it a smart choice for those seeking comfort, compliance and energy efficiency.

Through harnessing the power of LightTech, our Premium DGU’s offer high performance without compromise.

Insulation Improvement

%

A warmer space in winter.

As temperatures drop outside, the DGU Premium range offers exceptional insulation properties that keep your home comfortable and energy efficient, even in the coldest months.

With insulation capabilities 76% more effective than standard single glazing, DGU Premium ensures that precious warmth remains trapped indoors where it belongs. This also means for lower heating costs over those colder months.

Solar Control Improvement

A cooler space in summer.

Whilst our winters may be cold, it’s no secret that Victorias summers get rather hot. This again leaves us with the issue of ensuring our spaces remain cool and comfortable despite the much warmer external temperatures.

With improved solar control DGU Premium is 32% more effective than standard single glaze when it comes to blocking solar heat, making it an ideal choice when selecting which DGU best suits your home or projects needs and requirements.

Tilt

Tilt-angle (°)

Angle of the glass relative to the horizon

  • Typical skylights with a slight pitch: 3-5°
  • Typical windows in vertical walls: 90°
Ug.w

Ug (W/m².K)

Heat-transfer coefficient (center-of-glass)

  • Heat transfer (W) per square meter (m²) of glass for each degree (C) of temperature difference
  • Lower implies better insulation

.w

NFRC 100-2010 Winter Condition

  • The standard environmental condition for Ug quoted in the Window industry
  • Useful as a reference for performance comparison between different glazing systems but can lead to inaccuracies if used to estimate energy consumption
  • Inside Condition:
    • Air and effective room temperature: 21 deg C
    • Room emissivity: 1
  • Outside Condition:
    • Air and effective sky temperature: -18 deg C
    • Effective sky emissivity: 1
    • Convection coefficient: 26 W/m².K
    • Wind speed: 5.5m/s windward
Ug.s

Ug (W/m².K)

Heat-transfer coefficient (center-of-glass)

  • Heat transfer (W) per square meter (m²) of glass for each degree (C) of temperature difference
  • Lower implies better insulation

.s

NFRC 100-2010 Summer Condition

  • The condition used to calculate SHGC
  • Ug.s better represents performance in warm environmental conditions
  • Inside Condition:
    • Air and effective room temperature: 24 deg C
    • Room emissivity: 1
  • Outside Condition:
    • Air and effective sky temperature: 32 deg C
    • Effective sky emissivity: 1

    • Direct solar radiation: 783W/m²
SHGC

SHGC (Range: 0 – 1)

Solar heat gain coefficient

  • Proportion of solar heat radiation transmitted
  • Generally lower SHGC is desirable for north and west facing windows for reducing air-conditioning cost in summer
  • However, higher SHGC for north and west facing windows would help reduce heating cost in winter
VLT

VLT (Range: 0 – 1)

Visible light transmittance

  • Proportion of visible light (380 - 720nm) transmitted
  • Generally higher VLT is more desirable
VLRf

VLRf (Range: 0 – 1)

Front Visible light reflectance

  • Proportion of visible light reflected on the external side of the IGU
VLRb

VLRb (Range: 0 – 1)

Back Visible light reflectance

  • Proportion of visible light reflected on the room side of the IGU
Tdw

Tdw-ISO (Range: 0 – 1)

Damage weighted transmittance

  • Proportion of colour fading radiation transmitted
  • Lower Tdw-ISO means lower risk of colour fading
  • Accounts for the colour fading potential of both UV and visible spectrum
Tuv

Tuv (Range: 0 – 1)

UV transmittance

  • Proportion of UV radiation (280 - 380nm) transmitted (Range: 0 – 1)
  • Not recommended as a metric for assessing colour fading potential
  • Visible spectrum could account for as much as 40% of the fading from solar radiation
Sel.

Selectivity (VLT/SHGC)

Ratio of visible light transmittance over solar heat gain coefficient

  • Useful for comparing spectral selectiveness of the low-E coating
  • Higher selectivity means less visible light is sacrificed to lower solar heat gain

Example:

  • Sel. in the 0.5 - 0.8 range results from the use of Grey glass; less visible light is transmitted vs infrared radiation
  • Sel. in the 1.9 - 2.2 range results from the use of LightTech LI Max; less infrared radiation is transmitted vs visible light
