The full published spec on each Avery Dennison film Apex carries — light, heat, glare, UV. No marketing math. If you want to compare the details before you decide, this is the page.
Avery names films by a series number — 70i, 35i, 20i. It's a rough family designation, not a measurement. The film's actual visible light transmission is usually a few points off it.
So SP e-Lite 70i measures 66% light in, and NT PerLite Ceramic 35i measures 40%. Both are correct — the name is the series, the table is the spec. Every number below is the measured, published figure.
The clearest way to cut heat. Ceramic-based, almost no mirror look, keeps the view close to untouched. Our most-requested residential film.
Within about 10 miles of the ocean, e-Lite 45i and 70i have to be edge-sealed with neutral silicone. That's most of our coastal Marin and Sonoma work, and it's included when we quote it.
Grey-neutral and very low reflectance — the glass reads as glass, just calmer. The pick when a homeowner hates the tinted-office-building look.
PerLite 70i is the one interior film that doesn't lose heat rejection on dual pane — 31% single, 32% double.
Reflective on the outside for privacy and heat, neutral on the inside so you don't get the fishbowl effect looking out. The workhorse for hot west and south exposures.
Daytime privacy only. After dark, with lights on inside, reflective films work the other way around.
The economical dark neutral. No mirror at all — it absorbs rather than reflects, which is also why the glass matters.
Natura 05i and 15i absorb 68-75% of the solar energy hitting the glass, which loads the pane thermally. We confirm your glass type before recommending either one.
Maximum heat rejection, mirrored from outside. Commercial facades, west-facing glass walls, anywhere the sun is winning.
R Silver carries a shorter warranty than our ceramic and dual-reflective lines. We put the exact terms in writing on the quote.
Exterior-applied, and the highest heat rejection in the whole catalog. It stops the energy before it ever enters the glass assembly.
All exterior films are edge-sealed with neutral silicone as part of the install.
Privacy, branding and blackout. Bathrooms, conference rooms, shower doors, street-level glass.
DS Matte is a privacy film first — 27% heat rejected is the lowest in our line. If you need privacy and heat, we pair it or go a different direction.
Thick clear films that hold the glass together when it breaks. Sold on thickness and certification, not on tint.
The Avery line tops out at 15 mil interior. If you've been quoted a thicker Avery safety film somewhere, that spec is worth a second look before you sign.
Every figure on this page is measured on single-pane clear glass, because that's the baseline the manufacturer publishes. Your windows are probably not that.
An interior film sits on the room side, after the sun has already crossed both panes. On a standard dual-pane unit, interior films typically lose 8 to 14 points of heat rejection. DR OptiTune 20i, for example, goes from 67% to 56%.
Exterior films do the opposite — they reject the energy before it reaches the assembly, so they gain on dual pane. R Silver 20X goes from 81% to 85%. That's why exterior is often the stronger answer on a dual-pane job, even though most shops never bring it up.
The manufacturer's dual-pane column doesn't say what's inside the insulated unit. It's a fair guide for ordinary clear dual pane and not something anyone should quote against a specific Low-E unit — including us.
Glass type also drives thermal stress: dark absorptive films on the wrong pane can crack it. We identify your glass at the measure, and if a film isn't safe on it, we say so and pick a different one.
At the free measure we log your glass type, orientation and shading, then give you the performance figures for your windows — not the brochure number. That's the version that goes on the quote in writing.
We'll measure, identify your glass, and put the real figures and the real price in writing. No obligation, no pressure.
Book a free measureWhere these figures come from. All values are Avery Dennison's published figures from the Architectural Window Film Design Guide and product data sheets, measured on single-pane clear glass. Light in is Visible Light Transmission. Heat rejected is Total Solar Energy Rejected (TSER) — the whole-spectrum number. We deliberately don't publish infrared-only rejection figures, which run far higher and are the most common way heat performance gets overstated in this industry.
Where a number is blank, the manufacturer doesn't publish it for that film. We'd rather leave it empty than estimate it.
Series numbers are product names. 70i, 35i and 20i identify the film, not its light transmission. Measured light transmission is the Light in column above. Specifications are the manufacturer's and are subject to their revision; final performance depends on your glass, and we confirm it in writing before any work is booked.
