TSER
The honest numberTotal Solar Energy Rejected
Accounts for all three bands — UV, visible and infrared — so it reflects the total heat kept out. This is the figure that best predicts real comfort. Always ask for it.
Our expertise
We treat window film as a science, not a sale.
Singapore's market is crowded with installers offering the same handful of films. Our edge isn't the product — it's the analysis behind the recommendation.
The OnlyFilms approach
A site-specific recommendation, every time.
We never quote a film before we understand your home. Here's how we arrive at the right answer.
01
Understand the orientation
We start with how your unit faces the sun. A west-facing facade in Singapore behaves nothing like a north-facing one — the film that suits each is different.
02
Read each room's function
A bedroom, a home office and a living room have different needs for light, privacy and glare. We recommend per room, not one film for the whole home.
03
Match film to the metrics
We translate TSER, IR rejection, VLT and glare reduction into plain language so you understand exactly what you're getting — and why.
04
Install with precision
Clean, bubble-free installation by experienced hands, with the film backed by manufacturer warranty for long-term peace of mind.
The problem
Why generic films fail.
The most common mistake isn't a bad film — it's the wrong film for the window. A dealer keen to close will fit the same product everywhere, regardless of which way the glass faces or what the room is used for.
The outcome is predictable: a west-facing living room still bakes in the afternoon, a bedroom is darker than it needs to be, or a home office still battles screen glare. The film was never matched to the problem.
Orientation ignored
Same film on a west and a north facade — only one of them needed it.
One metric in isolation
A flashy IR number quoted alone, with no mention of TSER or glare.
Room function overlooked
A bedroom, study and living room treated identically despite different needs.
The metric
TSER vs IR Rejection.
Sunlight reaching your window is made of three parts. Understanding them is the key to reading any film's spec sheet.
Energy in sunlight
Ultraviolet
Visible light
Infrared
~3% ultraviolet — Causes fading
~44% visible light — What you see by
~53% infrared — Felt as heat
IR Rejection
Often quoted aloneInfrared Rejection
Measures only the infrared band. A film can show a very high IR number yet reject far less total energy. Useful — but misleading if it's the only figure you're shown.
Good to know
Questions, answered.
The things homeowners ask us most before choosing a film.
- What is TSER and why does it matter?
- TSER stands for Total Solar Energy Rejected. It combines the rejection of visible light, infrared and ultraviolet energy into one figure, so it's the most honest single indicator of how much heat a film keeps out — and how cool a room will actually feel.
- Is a high IR rejection number enough?
- Not on its own. Infrared rejection only measures one slice of the solar spectrum. A film can advertise 90%+ IR rejection while having a much lower TSER. We always quote both so you can compare films fairly.
- Why does window orientation matter in Singapore?
- A west-facing facade receives intense afternoon sun and heat, while a north-facing one is far gentler. The right film for each is different. Choosing by orientation is the single biggest factor in getting comfort right.
- Will solar film make my home dark?
- No. Modern ceramic and spectrally-selective films reject heat while keeping high visible-light transmission, so rooms stay bright. We match the look you want with the performance your facade needs.
- Do window films block UV?
- Quality films block around 99% of UV rays, which protects your skin and prevents furniture, timber flooring and artwork from fading over time.
