The physics of window film, explained honestly.
48 chapters across 5 series — from the energy leaving the sun to the spec sheet in your hand. Independent, ad-free, and built to teach, not sell.
The Series
A guided path through solar energy, surface physics, measurement, technology, and proof. Read it here, follow along on social, or get one chapter a day by email — same lessons, your choice of channel.
The Energy Story
Where solar energy comes from and what it is. No glass, no film — just the energy itself. The vocabulary every later series depends on.
Series 2At the Surface
What happens when solar energy hits glass and interior materials — reflection, absorption, transmission, re-radiation, convection. Pure surface physics.
Series 3The Measurement Story
Specs, standards, and the honest evaluation of performance claims. The intellectual core: these chapters evaluate numbers, not products.
Series 4The Technology Story
How window film is actually built — construction methods, materials, mechanisms, dyes, haze, labels, and economics.
Series 5Proof & Practice
Independent verification and hands-on experiments that turn the catalog's physics into evidence you can check yourself.
Straight answers
The questions people actually ask about window tint — answered with physics, not a sales pitch.

Standalone myth-busts on the specific questions people ask about tint — each one grounded in the physics and independent sources.
What Actually Fades Your Floors and Furniture
Everybody has seen it. You slide the rug over, or lift the lamp that's sat in the same spot for six years, and there it is — a hard-edged rectangle of the…
Why Window Film Goes on the Inside of the Glass
Almost every window film you'll ever have installed goes on the inside of the glass, and to a lot of people that feels backwards. The sun is outside. The…
Window Film Adhesive: Half of What Gets Blamed on the Glue Isn't the Glue
The adhesive is the most blamed and least understood layer in a window film. Bubbling, peeling, that purple cast an old film takes on, the milky haze that…
