Avery Dennison SP e-Llite 45i

The Avery Dennison SP e-lite 45i is a spectrally selective solar control film. level of visible transmittance, this film provides a standard amount of glare protection. This solar control film is spectrally-selective, giving it a higher light/heat ratio than conventional films and allowing it to reduce solar heat gains with less of a negative impact on daylight transmission and views.

Hub Highlights:

Reduced visible light transmission provides moderate glare reduction
Spectral selectivity provides a high (greater than 1) light/heat ratio
Rejects more than 50% of solar heat

Type	Spectrally selective solar control
Solar Heat Gain Coefficient (SHGC)	0.45
Visible Transmittance (Tvis)	0.46
U-value (U, W/m2 K)	5.63
Light/heat ratio	1.01
Installation Procedure	Same as for standard film, with the following additional considerations: - Sealing of film edges may be recommended for applications on non-vertical glazing, or less than 10 miles from the sea - Installation may not be recommended during precipitation (rain, snow) or when exterior air temperature is expected to drop below freezing in the following 15 days
Operation and Maintenance (O&M) Procedures	Window film should be washed with cleaning agent for windows or mixture of soap and water and wiped using a soft cloth or clean synthetic sponge. No bristle brushes, abrasive cleaning materials, or ammonia-based products are recommended. Paper towels may produce microscopic scratches that damage the film over time.
