Choosing a Greenhouse Curtain/Screen
When choosing a green house curtain/screen, there are several factors to consider. Thermal curtains reduce greenhouse heat loss in cold weather. Rolling screens provide blackout on south-facing walls. Sidewall curtains form interior partitions. ICFR (Infrared Curtain Film Reflectance Ratio) curtains increase greenhouse heat retention. The correct location for curtain/screen systems is critical to reducing energy costs. Depending on your greenhouse’s slope and orientation, it may be necessary to place one overhead horizontal slice at least 1 foot below the gutters.
Thermal curtains reduce greenhouse heat loss in cold weather
Thermal curtains are textiles placed between the crop and the greenhouse. They prevent the greenhouse from losing heat during the nighttime. Because they are movable, thermal curtains can either be fully closed or partially open. Some thermal curtains can reduce the amount of energy needed to heat the greenhouse in cold weather by 30%. Here’s how thermal curtains work. They’re usually installed below the gutter and retract easily to allow for more air circulation.
High-tech curtain fabrics are designed to reflect infrared radiation. These rays are emitted by plants, benches, and greenhouse structures. Thermal curtains help reduce this energy loss, which is responsible for about 70 percent of greenhouse heating costs. They also reduce summer cooling loads, which can increase energy bills over time. They are also useful for photoperiod control and summer shading. This will ensure that your crops receive the heat they need.
Thermal curtains are available ready-made in many materials. They can be made from polyolefins, a material with good rolling properties. They are also fire-retardant, which is important in the horticultural industry. One of the most effective materials is L.S. Svensson fabric, which is clear and provides 78% light transmission. The light-reflecting qualities of this material allow for a 45-percent energy saving.
Thermal curtains can be made in a variety of lengths and widths. Many manufacturers offer a wide variety of curtains. For a full-looking look, try using several panels that extend over the entire width of the window. The height and width of these curtains should be about one-half to three-times the width of the window. This will help reduce the greenhouse’s overall temperature. It’s also important to consider the shade-reflecting ability of the curtains.
Sidewall curtains form interior partitions
Depending on the climate of your region, sidewall curtains can help keep your greenhouse comfortable in warm or cold temperatures. Sidewall curtains are commonly made of polyethylene film, which offers excellent ventilation and passive cooling. Some greenhouses use sidewall curtains to protect livestock from harsh winters. This kind of curtain is primarily used in greenhouse barns where livestock are housed. In addition to protecting livestock from cold weather, they also help keep out heat during cold weather.
Curtain walls also help cut down on greenhouse light while reducing greenhouse cooling costs. They reduce light by up to 1%, which is perfect for light-deprivation growers. Curtain walls are available in two types: internal and external. In either case, you must choose the type that will best suit your needs and budget. Sidewall curtains are available for greenhouses with up to seven plants per square foot.
ICFR heat retention curtain
If you’re looking for energy-saving, climate-controlled windows in your home or office, consider investing in an ICFR heat retention curtain/screen. These products use triple-layered fabric that is designed to minimize heat loss and retain heat. This allows them to regulate temperatures by direct transfer, diffusion, and convection. The benefits of these products include improved energy efficiency and reduced energy bills. Besides being energy-efficient, these products also provide privacy and reduce glare.
Gutter-to-gutter curtain system
A gutter-to-gutter greenhouse curtain/screen is a good way to control the heat and moisture in a greenhouse. This system works by suspending the fabric from the roof with hooks. This method eliminates wire-to-cloth contact and wear. The original purpose of this type of system was to fold the fabric up when traveling long distances. A deep fold in the cloth creates a narrow shading projection. This type of system is more wind resistant and works well in greenhouses with open roofs, sawtooth vents, or exposed areas.
A gutter-to-gutter greenhouse curtain/screen uses a single or multiple panels of fabric and is installed below the gutter. It can be drawn closed at night or retracted during the day. The curtain system is made to operate from truss-to-truss or gutter-to-gutter. A truss-to-truss system is more common, but it is possible to buy one that is tailored to your greenhouse’s needs.
A gutter-to-gutter greenhouse curtain/screen is another type of shade-control system. With this system, the curtain will draw at gutter height and cover the area between the trusses. This system can be installed on a variety of greenhouse structures, depending on the amount of rain and sunlight they receive. You can also choose a truss-to-gutter system if you have a greenhouse with 10 foot trusses.
