Time to Consider Double Screening?

With double screening, you double your ability to heat, cool and light on demand, because with the touch of a button you’re able to expand or retract curtains in any combination to provide the best climate possible for your crop.

Climate is king in the greenhouse world, and proper management of the greenhouse environment presents as many challenges as it does opportunities. Do you shade at the expense of energy savings? Do you install an energy screen, then still have to whitewash? Luckily growers, especially vegetable growers, are finding the more versatile practice of double screening gives them ultimate control of their greenhouses. Long a staple in European horticulture, this versatile technology is moving into North America.

Feeding the Climate

For greenhouse production, a wide combination of screens is available. Depending on goals, a grower can select the screens that give the optimal climate. When you have a single layer of screens, you end up having to decide which characteristic is most important to you, and then install the screen that offers that benefit.

For example, a clear energy savings screen will help with your utility bills, but will not provide significant shade. An aluminum shade will provide higher energy savings plus shade, but at the expense of light, a particular issue during winter.

Double screening lets you adapt your greenhouse to the time of year and the climate. Think of it as going to the beach: you take 50 SPF and 15 SPF sunscreen, and you apply each at different times depending on the sun position, light level and time of year. Likewise with two greenhouse screens, you have the flexibility of using shade in late spring and summer and an energy savings screen from late September through May.

With double screening, you double your ability to heat, cool and light on demand, because with the touch of a button you’re able to expand or retract curtains in any combination to provide the best climate possible for your crop.
