Every window film install starts with the same question: which construction? Most customers don’t know enough to ask. Most shops have 30 seconds to explain it. This guide is the longer version — written for installers who want the real answer.
Glacier sells ceramic film below carbon price.
We only manufacture nano-ceramic. Carbon is OK but second-best.Dyed and metalized fail the modern vehicle. By cutting out the distributor markup, we land top-tier ceramic below what most shops pay for mid-tier carbon.
Ceramic film
What Glacier makes
Ceramic films use nano-ceramic particles embedded in the film construction. Those particles do two things: reject heat across a wide section of the infrared spectrum, and stay non-conductive (so they don’t mess with car electronics).
Heat rejection is the highest of any current construction — top-tier ceramic can hit 60–65% TSER (Total Solar Energy Rejected) and reject more infrared than dyed or metalized films at the same VLT. For modern cars with antennas embedded in glass, ceramic is the only construction that doesn’t interfere with GPS, radar, satellite radio, or cellular signal.
The tradeoff is cost — ceramic film is the most expensive tier. The reason Glacier exists: by manufacturing direct, we pull out the distributor markup that puts ceramic out of reach for high-volume shops. You install the right product, at a price that makes sense.
Carbon film
Not sold by Glacier
Carbon films use a carbon-infused construction that doesn’t fade or shift purple over time — the failure mode every shop has had to warranty out on cheap dyed film. Heat rejection is good (not ceramic-good), color stability is excellent, and like ceramic, carbon doesn’t interfere with electronics.
Carbon is a legitimate mid-tier product. The reason Glacier doesn’t make it: the gap between mid-tier carbon and top-tier ceramic is narrower than the price gap suggests — especially once you take Glacier’s direct pricing into account. Rather than make two products that compete with each other, we picked the one without tradeoffs.
Metalized film
Not sold by Glacier
Metalized film uses a thin metal layer for reflective heat rejection. It works — high heat rejection at lower film cost — but the metal layer interferes with GPS, radar, satellite radio, and cellular signal. For modern cars, that’s usually a deal-breaker.
Where metalized still works: architectural installs where there are no antennas to interfere with, and high-rejection solar control on commercial buildings. For automotive, avoid.
Dyed film
Not sold by Glacier
The entry tier. A dye layer between adhesive and topcoat provides privacy and glare reduction at the lowest price. Heat rejection is the worst of any construction. Within 2–4 years, dyed films often shift purple as the dye breaks down under UV. That’s the warranty call you don’t want.
Where dyed still gets installed: cost-driven shops chasing the lowest sticker. Glacier doesn’t make dyed because we don’t want our shops in the position of installing a product that’s coming back in three summers.

How to pick
- Premium / luxury installs: Ceramic. Period.
- Daily drivers, longer ownership: Ceramic. Direct pricing makes it the right call, not just the right product.
- Modern cars with active antennas: Ceramic. Anything metalized is a callback waiting to happen.
- Architectural / commercial: Ceramic. Same logic — pay once, install once.
- Short-life or budget installs: If you’re going to install dyed, install it knowing the customer will be back.
