3M's multilayer optical film separates heat from daylight right at the glass. Hundreds of nanolayers send back up to 97% of the sun's infrared while the view stays perfectly clear, with no metal and no mirror look. 3M has led this category since 1966.
3M invents sun-control window film and patents it, opening the category.
3M perfects non-metallic multilayer film: heat rejection without metal, mirror or signal loss.
Millions of square feet of 3M film are installed globally, fitted locally by authorized installers like Protek.
The first patent for sun-control window film was 3M's, granted in 1966. Six decades on, 3M still runs its films through the harshest tests in the industry, including bomb-blast simulation, accelerated weathering and years of UV.
3M supplies its film only through trained, authorized dealer installers. Protek is one. The film is matched to your glass and fitted to specification, then backed by a 10-year warranty on the product and our workmanship.
Most heat-rejecting films lean on a thin layer of metal, which brings a mirror sheen, corrosion over time and weaker phone reception. 3M builds heat rejection optically instead: hundreds of nanolayers, each thinner than a wavelength of light, tuned to reflect infrared while visible light passes straight through.
No metal means nothing to oxidise, haze or rust at the edges over the years.
Cell, GPS and Wi-Fi pass straight through, unlike metallised films.
True colour, sharp view, no dark tint and no mirror box. The building reads as itself.
Prestige performance climbs with the sun, peaking when heat is worst.

3M's catalogue runs deeper still, including the Ceramic, full Prestige and Ultra Prestige ladders. We bring in the right grade for your project on request; the films above are what we hold and fit most often.
A landmark on Lahore's commercial skyline, the tower stands behind a full curtain-wall of glass that takes direct sun for most of the working day. 3M film was specified to cut the solar heat driving the cooling load, screen out fading UV, and add a layer of protection that holds glass together if a pane is ever struck.

If budget is the priority, we also fit strong value films from TotalGard and Reflectiv, and we'll advise honestly on a site survey.
No. 3M's premium Prestige and Ultra films are non-metallic, multilayer optical films, so there is no metal to oxidise and nothing to interfere with cell, GPS or Wi-Fi reception. That is a key advantage over older metallised and reflective films, which can corrode at the edges and dampen signals.
Yes. The 3M SAS5 film combines anti-shatter glass retention with 41% solar heat rejection in one layer, and 3M's Scotchshield Ultra Prestige range pairs full spectrally-selective sun control with tear-resistant safety construction. We confirm the right combined film on a site survey.
The 3M films we install in Pakistan carry a 10-year warranty. 3M backs its window films with one of the most comprehensive manufacturer warranties available, and because Protek is an authorized 3M installer, the workmanship of the installation is covered as well.
