Nanoparticle technology doesn't lose performance over time

A persistent rumor claims that ceramic or “IR-blocking” tints eventually stop working— that a decade down the road, their heat-rejection numbers fade just like a cheap dye. Some sales reps even hint that competing brands quietly rely on short-lived chemistry. It’s time to separate fact from folklore.

Two Very Different Ways to Block Heat

Why Flexfilm Uses Elemental Nano-Particles

• Permanent IR rejection — sunlight can’t “evaporate” tungsten or ATO; Day-1 shielding equals Year-10 shielding.
• True color stability — heat blocking isn’t tied to organic dyes, so shade = shade for life.
• Warranty that means something — a lifetime guarantee is credible when chemistry is literally rock-solid.

Bottom Line

Every Flexfilm product—Terraflex, Panaflex, and Nanoflex—uses inorganic nano-particle technology. These particles are elemental; they don’t oxidize away or wash out like dyes. So when you hear that ceramic tint “loses its IR blocking,” remember: durable chemistry never fades.
