Closed shading screens

One screen, two purposes

Phormium offers both diffuse and aluminum closed shading screens.

Phormium’s newest, highly diffusive shading screen is Pearl. With a hortiscatter value of 83% and a PAR shading coefficient of 28.5% according to NEN 2675, Pearl strongly scatters incoming light while blocking only a limited portion of it. Pearl is typically used as the bottom screen in Phormium’s OptiPAR system.

Closed diffuse screens like Phormium’s Clima+ or PhormiTex Lumina shade the sunlight away in order to avoid burning of the top of the plants and make the light diffuse at the same time. This way, light is spread evenly over the crop resulting in higher and more constant crop yields over the complete area.  This will create an agreeable climate on hot summer days. 

The aluminum PH and PhormiTex screens have outstanding energy saving capacities. When the outdoor temperature drops sharply in winter, energy conservation becomes even more important. The aluminum woven structure provides a high level of insulation and results in significant energy savings throughout the screen's entire service life.

Aluminum screens are the perfect night screens. Energy saving is significantly maximized during the night and the screen is opened soon after sunrise. 

All closed screens from Phormium contain a state-of-the-art acrylic yarn that will attract condensation droplets on the downside of the screen and transport the moisture to the upper side of the screen where it will evaporate. Excess moisture is easily transported. This has a positive effect on the greenhouse environment and crop performance. Thanks the network of acrylic yarn in the screen, humidity will be able to escape through the screen.

Recommended gable screens

Phormium recommends combining these screens with the reinforced gable screen PHL 55.
