Saint-Gobain Solar Gard Ecolux 70

The Saint-Gobain Solar Gard Ecolux 70 is a low-emissivity spectrally selective film. Its low-emissivity properties improve thermal insulation and its spectrally selective properties provide a high degree of solar control, with minimal impact on daylight transmission and views. This film has a very high light to heat ratio.

Hub Highlights:

Minimal impact on views due to high visible light transmission
Spectral selectivity provides a high (greater than 1) light/heat ratio
Rejects more than 50% of solar heat
Low-emissivity properties provide moderate reduction in winter heat losses

Type	Low emissivity
Solar Heat Gain Coefficient (SHGC)	0.45
Visible Transmittance (Tvis)	0.66
U-value (U, W/m2 K)	3.84
Light/heat ratio	1.46
Installation Procedure	Pre-installation: low-e film may not be suitable to high traffic areas, high humidity areas, areas with high salt exposure, and areas where the indoor-facing surface of the film may be exposed to direct sunlight. Installation procedure: Same as for non-low-e film but requires more careful handling due to more sensitive nature of film, and additional squeegeeing due to lower permeability. Post-installation: Same as for non-low-e film but air bubbles may persist for longer (i.e., several months), depending on environmental conditions. In some cases, film replacement may be necessary.
Operation and Maintenance (O&M) Procedures	Care of low-e films is similar than other window films, with the main difference that low-e films can be more prone to showing fingerprints and other oily marks and may need to be cleaned more carefully.
