5 Advantages of Energy Curtains Not to Miss

When it comes to adding energy curtains (sometimes referred to as thermal blankets) to a greenhouse, everyone focuses on energy savings. And certainly, energy savings should be a major factor in any greenhouse grower’s decision to purchase greenhouse energy curtains. In northern climates, winter growing adds expensive heating costs to the most diligent greenhouse operation. A well-designed and properly installed energy curtain can reduce winter heating bills by up to 50% and, in some cases, more. In turn, energy curtains when used properly in hot summer weather can cut back on electricity needs from fan venting, and help maintain higher night time temperatures when the sun goes down, enhancing greenhouse insulation and heat retention.

But there are 5 other considerations worth adding to your analysis when considering the value of an energy curtain in your greenhouse.

1. Greenhouse Energy Curtains Help Control Humidity

When used properly in conjunction with roof vents, an energy curtain can help balance humidity in the greenhouse by allowing fresh cool air in, while still providing a physical barrier to greenhouse insulation and greenhouse heat retention. This prevents the cold air from dropping to the crop. Learning how to control the curtains as part of your total environmental control is essential. If the curtain needs to be closed and humidity levels are too high, then opening the curtains a crack and opening your windows will help lower humidity.

2. Energy Curtains Can Be Used for Summer Shading

The flexibility with energy curtains allows growers to shade when the plants need it. By using your greenhouse energy curtains system to adjust light levels as well as temperature, you have one more tool for providing the ideal growing environment for your specific crop. When working with your greenhouse design team to layout the greenhouse curtain system make sure you don’t miss this aspect of environment control, and set your zones according to the differences your crops may need.

3. Greenhouse Energy Curtains produce healthier plants by reducing daytime temperature fluctuations

Getting rid of the peaks and valleys in a winter day’s temperature range will most certainly improve the bottom line as far as reducing heating costs, enhancing greenhouse heat retention, and boosting greenhouse insulation. And that is only the beginning. Daytime temperature fluctuations may be causing your boilers to perform lower than expected, which reduces boiler efficiency and affects maintenance costs and lifetime use of a boiler. These rapid temperature changes also add stress to your plants. So by properly timing the opening and closing of a greenhouse energy curtain with environmental controls that measure outdoor & indoor temperatures against desired growing temperatures, you can even out the peaks and valleys and provide a smoother temperature transition for healthy plants.

4. Energy Curtains May Qualify for a Government Rebate

In many parts of the United States and Canada, and in Europe, energy savings is high on government agendas. Get involved with your local chamber of commerce, and your regional, state, and provincial government, and learn what rebates, and tax-saving incentives are available for energy-efficient upgrades like greenhouse energy curtains. If there is money available to help you improve your business, then knowing what your options are will help you make smart decisions.

5. Energy Prices Won't Likely Go Down, so Energy Savings Are Bound to Go Up

When considering the ROI for greenhouse energy curtains or any other capital investment, including an assessment of the future makes good sense. Take a look at your energy bills for the last 5 years, and consider trends. How has your price changed? What has your average usage been? If you had a mild winter and dramatically reduced your heating expenses, also consider the harsher winters, because the future will have both. This is where greenhouse insulation and greenhouse heat retention play a crucial role in energy savings.

Thermal greenhouse energy curtains are only one consideration that modern commercial growers have available to assist in providing the ideal growing environment for the crop. Additional curtain considerations like shade, or blackout (light deprivation), or double and triple hung curtain options, and truss to truss vs gutter to gutter operation, can also be discussed with a GGS greenhouse specialist.
