01

Film is always active

Film works whether or not anyone adjusts anything, and keeps the opening visually open.

02

Shades are adjustable

Shades add control when needed and can provide night privacy and darkness.

03

What film cannot do

Reflective film does not guarantee night one-way privacy when interiors are brighter. Film cannot provide blackout. UV reduction helps, but fading is multifactorial.

04

Security film

A separate category for glass retention and forced-entry delay. It does not replace shades for privacy or darkness.
