A significant step up from standard Double Glazing.

Considered a step up from our DGU Essential Range, Pro units utilise pyrolytic Low Emissivity glass (LowE). Also known as a “Hardcoat” to significantly boost thermal performance and slightly increase solar control, whilst maintaining a high visible light transmittance.

Whilst Hardcoat double glazed units don’t provide the peak performance that can be delivered by Premium and Max, their importance should not be understated, and in certain environments the DGU Pro range may still be the best suited option to deliver optimal results.

Insulation Improvement

%

A warmer space in winter.

As temperatures drop outside, the DGU Pro range offers a significant improvement in thermal retention, this helps keep your home comfortable and energy efficient, even in the coldest months.

With insulation capabilities 72% more effective than standard single glazing, DGU Pro ensures that precious warmth remains trapped indoors where it belongs. This also means for lower heating costs over those colder months, making your home more energy efficient.

Solar Control Improvement

Greater Summer Comfort

Victoria’s warm summers make keeping your home cool essential. DGU Pro provides 23% better solar control than single glazing, reducing heat transfer. For optimal comfort, especially in extreme heat, we recommend considering the Premium or Max ranges. Consult your fabricator to find the best option for your project.

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

NFRC 100-2010 Summer Condition

  • The condition used to calculate SHGC
  • Ug.s better represents performance in warm environmental conditions

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)

  • 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

UV transmittance

  • Proportion of UV radiation (280 - 380nm) transmitted (Range: 0 – 1)
  • Not recommended as a metric for assessing colour fading potential

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
