Residential
A strong fit for waterfront and view homes, large sliding doors and picture windows, and HOA communities that limit dark or reflective film.
Window film solution
Maintain your views with spectrally selective film
For homes and buildings where the view is the point, spectrally selective films target the invisible part of sunlight that carries heat, while letting most of the visible light through.

Short answer
Spectrally selective window film is designed to block a large share of infrared and ultraviolet energy while transmitting most visible light. The result is a film that reduces solar heat with very little change to how bright or clear the glass looks. It's the usual answer to the question 'which film reduces heat without darkening the glass?' — though it rejects less total heat than darker or reflective films.
You want less heat — not a darker room
Many homeowners, especially on the water, want the heat gone but the view untouched. Traditional dark or mirrored films solve the heat and change the look of the house.
Spectrally selective film is for the people who would rather keep the glass looking like glass.
How spectrally selective film works
Sunlight is a mix of ultraviolet, visible light and infrared. Infrared carries a large part of the sun's heat but contributes nothing to the view.
A spectrally selective film is engineered to pass much of the visible spectrum and reject much of the infrared and UV. The industry measure is the light-to-solar-gain ratio (LSG): visible light transmitted relative to solar heat gain. The higher the LSG, the more 'selective' the film.
For homes and businesses
Where it helps
Commercial
Useful for lobbies, showrooms, restaurants and offices that want daylight and a natural exterior appearance while trimming solar heat gain.

Additional film lines
Global and Express window films
- Global Transcend 70–80
A high-light spectrally selective film for homeowners who want heat control with almost no change to the view.
Product names are taken from manufacturer product pages. Performance figures vary by shade and glass; we'll provide the manufacturer's technical data for the specific film we recommend.
Where it fits — and where it doesn't
- Expect a meaningful heat reduction with a light appearance, not the maximum heat rejection available.
- It adds little glare control or privacy. If glare is the main complaint, a tinted or dual-reflective film may be better.
- High-light films still need a film-to-glass compatibility check on insulated and low-E glass.
What we check first
- Whether heat, glare, privacy or view is your top priority
- Existing glass coatings (low-E) and glass type
- How the film looks at different times of day

Questions
Common questions
What is spectrally selective window film?
It's a window film engineered to reject much of the sun's infrared and ultraviolet energy while letting most visible light through, so it reduces heat without noticeably darkening the glass.
Which window film reduces heat without darkening the glass?
Spectrally selective films, and some light neutral solar films, are designed for this. They reduce solar heat with a light, low-reflective appearance. They won't reject as much heat as darker films, so we'll explain the trade-off for your windows.
