If you have searched for window film, you have probably seen the terms reflective, frosted and solar used interchangeably online. They are actually three very different products built to solve three different problems. Picking the wrong one is the single most common — and most expensive — mistake homeowners make. This side-by-side comparison clears it up.
Solar (heat reduction) film
Solar film is built primarily to reject heat and UV while keeping visibility. Most premium solar films are nearly invisible from inside and outside — they look like clear glass. Best for: hot rooms, energy savings, UV protection for furniture and timber floors, north and west-facing glass, double-glazed windows where you cannot afford a reflective look. Typical heat rejection: 50–78%.
Reflective (one-way mirror) film
Reflective film uses a heavier metallic or ceramic coating to create a one-way mirror effect during daylight — you can see out but people outside cannot see in. It also rejects significant heat as a side benefit. Best for: street-facing windows, ground-floor privacy, west-facing glass that needs maximum heat rejection, retail shopfronts, units overlooking a neighbour. Typical heat rejection: 60–80%. Important: the one-way effect reverses at night when interior lights are on.
Frosted (privacy) film
Frosted film is translucent — it lets light through but completely blocks the view in both directions, 24 hours a day. It does not reject heat. Best for: bathrooms, ensuites, meeting rooms, office partitions, front door sidelights, anywhere total view-block is required day and night. Typical light transmission: 70–85% (so rooms stay bright).
Quick comparison table
- Heat rejection: Solar (high) > Reflective (high) > Frosted (none)
- Daytime privacy: Reflective (excellent) > Frosted (excellent) > Solar (minimal)
- Night privacy: Frosted (excellent) > Reflective (none) > Solar (none)
- Visibility through glass: Solar (full) > Reflective (one-way) > Frosted (none)
- UV rejection: All three (99%+ on quality films)
- Cost per m² installed, inc GST: Frosted ($70–$120) < Solar ($80–$150) < Reflective ($90–$180)
- Best for double glazing: Solar (ceramic) > Frosted > Reflective (check with installer)
Can you combine them?
Yes — and most Melbourne homes do. A typical combination is solar film on the living-area windows for heat and UV control, reflective film on a street-facing front room for daytime privacy, and frosted film in the bathroom and on the front door sidelights for 24/7 privacy. We can quote a mixed package in a single site visit.
How to decide in 30 seconds
- Hot room, want it cooler, do not want the look to change → Solar film
- Want privacy from the street during the day plus heat rejection → Reflective film
- Want privacy 24/7 in a bathroom or office → Frosted film
- Want all three in different rooms → Combine, that is what most homes do

Frequently asked questions
Can I combine reflective and frosted film in the same house?+
Yes — most Melbourne homes use a mix. Reflective solar film goes on the street-facing living-area windows for daytime privacy and heat rejection, frosted film goes on bathrooms and ensuites for 24/7 privacy. We can quote both in a single site visit.
Does reflective film work at night?+
No. Reflective film relies on the brighter side acting as the mirror. At night, with interior lights on, the effect reverses and people outside can see in. For 24/7 privacy choose frosted film, or pair reflective film with blinds.
Which film is best for an office?+
Most offices need both: solar film on the perimeter windows for heat and glare control, plus frosted film on meeting rooms and partitions for privacy. See our commercial window tinting page.
Do any films offer all three benefits in one?+
Dual-reflective ceramic films come closest — strong heat rejection, daytime privacy and a low-glare interior view. They are the most popular premium choice for street-facing homes and apartments.
Which film is cheapest?+
Frosted film is the cheapest per square metre (typically $70–$120 installed inc GST), followed by solar film ($80–$150), then reflective ($90–$180), also inc GST. The right film for you is the one that solves your problem — going cheaper than that just means doing it twice.
