Thermal effect

This parameter defines the amount of light passing through the film and its diffusion. Properly diffused light ensures even sunlight distribution inside the tunnel. Optimal light levels support healthy plant development and increase crop yield.

Anti-condensation effect

Condensed water does not form droplets on the film surface but instead creates a thin layer that flows down towards the sides of the structure. This effect works best when the roof has the correct slope — a minimum of 15°, with an optimal angle of around 30°.

Anti-fog effect

Reduces fog formation inside the tunnel, especially during early mornings and evenings.

Thermal effect with EVA additive

Reduces heat loss caused by radiation by reflecting infrared energy back into the structure. Thanks to the EVA additive, the temperature difference between day and night is significantly reduced. This can lead to noticeable heating cost savings and, in unheated structures, reduces the risk of frost damage.

Additional mechanical strength

The film is resistant to tearing, stretching and punctures. This is especially important for structures exposed to strong winds or built with lighter construction materials (e.g. wooden frames).

Film with anti-condensation additive

Ensures optimal light transmission into the tunnel.

Film without anti-condensation additive

Water droplets form on the surface, reducing light transmission by up to 15%.
