Clear Glass

Available in a variety of sizes and either clear or toned options, our standard clear float glass features a smooth, flat surface that provides excellent clarity, minimal distortion, and high daylight transmission.

Ideal for a range of applications, including general glazing, laminating, toughening, and decorative finishes, FGS Standard Clear Float Glass can also be used in double-glazed units to improve solar and thermal performance. Note that the tone and light transmission may vary with thickness, which is an important consideration for achieving consistent color uniformity in your design.

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

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
  • 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
    • Convection coefficient: 15 W/m².K
    • Wind speed: 2.75m/s windward
    • 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

Considerations

Things to Consider

Design Considerations

The appearance and performance of Clear Float Glass can vary based on thickness, influencing both tint and light transmission. It is important to note that annealed glass is not appropriate for areas where safety glass is required.

Managing Thermal Stress

Clear Float Glass absorbs solar heat when exposed to sunlight, which can result in thermal stress and potential glass fractures, especially in partially shaded areas. To prevent this, we recommend heat treatments like heat strengthening or toughening.

Installation Best Practices

To reduce the risk of thermal fracture, ensure that the edges of solar control glass remain undamaged during installation.
