Heat rejection film from 3M
Blocks the sun's heat and glare by day, yet a low interior reflectivity keeps your view out clear at night. Strong privacy with none of the mirror-box feeling after dark.
Night Vision 25 is built around a number most reflective films ignore: interior reflection of 9%, about the same as bare glass. Heat-rejecting films usually turn into a mirror on the room side after dark. This one keeps the evening view, which is why 3M named the series for it.
By day it rejects 63% of total solar energy on single clear glass and cuts solar heat through the pane by 52%, with glare down 73% at 24% visible light. On clear double glazing it still rejects 53% and cuts heat gain by 29%. UV block is 99.9% on every glass type, and a scratch-resistant coating with 3M's nano-technology keeps the colour stable as it ages.
The scale reference for this film is the Embarcadero Center towers: 345,000 square feet of Night Vision 25, with the energy saving paying back the installation in under a year. Within our 3M range it sits between Prestige 70, which stays clearer at 70% VLT but rejects less heat, and Silver P18, which rejects more but reads as a mirror from both sides.
Which glass it suits
Night Vision 25 goes on the inside face of the glass. 3M publishes its performance for single clear, single tinted and both kinds of double glazing, so it is safe across all of them: 63% of solar energy rejected on single clear glass, 53% on clear double glazing, and 99.9% UV block in every case.
