Spectrally Selective Clear Solar Control Films

Spectrally Selective Clear Solar Control Films

Spectrally Selective films are an advanced window film technology designed to selectively block certain wavelengths of sunlight — particularly heat (infrared) and UV — while allowing most visible light to pass through. The finished material is a polyester produced with more than 100 nanometric layers of PET

How do they work?

Unlike traditional films (dark or mirrored), which reflect or absorb all light components more uniformly, spectrally selective films: Block up to 97% of infrared rays, i.e. heat with a final yield of approximately 60% Filter over 99% of UV rays, which cause discoloration of furnishings and damage to the skin. Letting up to 60–70% of visible light pass through, keeping the environment bright and natural.

Main advantages

Maximum thermal comfort without obscuring the view or the environment. Almost invisible appearance: ideal for shop windows, luxury homes or listed buildings. Improved energy efficiency, both in summer (cooling) and in winter (some models also have low emissivity). No obvious mirror effect, unlike reflective films.

Disadvantages

Solar control is around 60% while with mirrored films it even exceeds 80% of Solar Energy rejected, they are technologically very advanced products and for this reason they are more expensive than classic mirrored metal-based films. They do not create a privacy effect and do not eliminate solar glare.

Where are they used?

Prestigious or historic buildings, where aesthetics are fundamental. Offices and residences that want to reduce heat without darkening the interiors. Museums or showrooms, to protect light-sensitive objects.

In summary:

Spectral selection films are a technologically advanced solution for those who want the maximum in terms of comfort, energy efficiency and aesthetic transparency.
