A color-shifting look
ThermaCore Color-Shift: a decorative color-shifting film
ThermaCore Color-Shift is a decorative film whose color appears to change with the viewing angle and the light. Ask us what is available.
Special order

- Shifts with viewing angle and sunlight
- A bold architectural look

- Dozens of ultra-thin layers
- Built by interference, not dye

- Great for retail and lobbies
- Works day and night
What color-shift film is
The film is built from very thin layers that bend light differently at each angle. As you move, or as the light changes through the day, the color seems to shift.
It is a decorative choice for feature glass and accents.
Not to scale. Layers differ by manufacturer.

How it is made
Inside a ThermaCore Color-shift film
Color-shift (dichroic-style) film is built from many ultra-thin optical layers that bend light by interference, so the colour you see changes with the viewing angle and the light. That effect comes from the layer structure, not from dye.
Window film starts as optical-grade polyester (PET), a clear plastic made in very thin, even sheets. Coatings are added in layers: dyes or ceramic particles, thin metal or metal-oxide layers applied in vacuum chambers, and a scratch-resistant hard coat. A pressure-sensitive adhesive and a protective liner go on the other side. The layers are laminated and cured, then slit into rolls and checked for clarity, coating evenness and defects before they ship.
Specs to ask for
Numbers that matter when you compare
Visible light
VLT is the share of visible light that passes through. Higher is clearer and brighter. Ask for a physical sample, because the effect depends on angle and light and photos do not show it well.
Total solar energy rejected
TSER shows how much of the sun’s total energy the film blocks, including heat. It is mostly decorative, so check the datasheet before relying on it for heat or UV control.
UV rejection
The share of ultraviolet rays blocked, which affects fading of floors, furniture and art.
Solar heat gain
Lower SHGC means less solar heat enters the room. It applies to the whole window, so ask for the film-on-glass value.
Glass compatibility
Film suits some glass better than others. We check your glass type and any maker restrictions before we quote.
What is covered
Ask for the film maker’s warranty and ours, including what each covers and for how long.
Exact figures come from the maker datasheet for the film we quote. We send the datasheet with your quote. Ask us and we will explain any number.
After install
Looking after it
Soft cloth, mild soap and a little patience in the first weeks keep this film clear for years.
Questions
Will you check my glass first?
Yes. Glass type matters, so we confirm the film suits your windows before we quote. If a film is not right for a window, we will say so.
Where do I find the exact specifications?
The manufacturer’s specification sheet for the exact film comes with your quote. We do not publish performance figures on this page, because they differ from roll to roll.
What does the warranty cover?
The warranty length is named on your quote. See our warranty page for the draft terms.
Will the colour change over time?
Optical-layer film is designed to keep its effect. Ask for the maker warranty terms.
Is it good for heat?
Some versions reduce a little heat, but its main job is the look.
