V-KOOL 75

About V-KOOL 75

V-KOOL 75 (VK75) delivers the highest visible light transmission in the V-Kool series — 77% VLT — making it the specification of choice when preserving maximum daylight is the primary requirement and some reduction in solar heat rejection performance is acceptable in exchange. VK75 transmits more visible light than VK70 while still providing 45.45% total solar energy rejection, 77.14% infrared rejection, and 99% UV block. In practical terms, it's the closest V-Kool film to being invisible.

For Philadelphia's historic district properties — Society Hill townhouses, Old City rowhomes, Chestnut Hill residences, and Germantown institutional buildings where preservation guidelines restrict anything that visibly changes the glass — VK75 is effectively undetectable while still providing meaningful UV protection and infrared rejection. The specification is also appropriate for north-facing glass and interior spaces where daylighting is already limited and any reduction in visible light would materially worsen the occupant experience.

Glass-heavy modern residences with expansive views also benefit from VK75. Where VK70 already reads as near-clear from the street, VK75 reads as essentially untreated — the film is present, the UV and infrared protection is real, but from a normal viewing distance nothing about the glass looks different. Philadelphia luxury residential clients who specifically value the connection to their surroundings often choose VK75 for its ability to protect the interior without altering the view.

All V-KOOL 75 specifications are NFRC-tested on 3mm single-pane clear glass. Available through Window Film Philadelphia with the same lifetime residential warranty and 10-year commercial warranty as the rest of the VK series.
