These two get lumped together as "window film" but they solve different problems, and mixing them up is the most common reason someone ends up with the wrong panel done.
Frosted film — for privacy and light, not heat
A translucent, matte film that scatters light rather than blocking it — the room stays bright, but the view through the glass is obscured. It's the standard choice for meeting rooms, office partitions, and glass doors where you want privacy without losing natural light. It can be cut into logos, patterns or full-panel coverage, and a gradient (clear at the bottom, frosted toward the top) is a common middle ground for storefronts that still want to display products at eye level.
Solar / tinted film — for heat and glare, not privacy
A tinted film rated by how much visible light it lets through (a lower percentage transmittance means a darker tint). Its job is cutting heat gain and glare from direct sun — relevant on Singapore's west- and east-facing glass in particular — while the view through the glass stays basically clear, just darker. It doesn't give privacy the way frosted film does.
Using both together
It's common to combine them deliberately: solar film across a full glass facade for heat control, with a frosted band or pattern only where privacy is actually needed (meeting room walls, a manager's office). They're applied as separate films, not one product, so each panel can be specified on its own.
