Fade & UV protection

Protection from UV rays and more

Large windows can let in beautiful light, but can also contribute to fading of materials in the home over time. The use of laminated glazing significantly improves the ability of the glazing to block the sun’s UV radiation. The addition of Guardian low-e coatings can reduce the risk of fading even further.

About Fade Resistance

Both UV radiation (300-380 nm) and visible light (380-780 nm) can contribute to fading, though the specific level of fading is dependent upon the chemistries of the individual furnishing material. While complete prevention of fading for specific materials would require careful analysis and evaluation, a metric known as the damage-weighted transmission (Tdw) can be useful in assessing the fading potential for a glazing.

The Tdw represents the combined transmission of UV and visible light, factoring the correlations between individual wavelengths and experimental instances of material fading. This metric can be readily calculated with our Glass Analytics suite ( https://www.guardianglass.com/us/en/tools-and-resources/tools/glass-analytics ) for a range of prospective glazing compositions.
