Greenhouse insulation quilt selection of 7 key factors
In the cold season, the maintenance of temperature in the greenhouse is the key to the healthy growth of plants. In order to maintain the appropriate temperature in the greenhouse in the cold weather in winter, the choice of thermal insulation quilt becomes crucial. How to choose the appropriate thermal insulation quilt is not only related to the thermal insulation effect of greenhouse, but also affects the yield and quality of plants.
✅1. Material selection
The material of thermal insulation quilt directly determines its thermal insulation effect and service life. At present, the common materials of thermal insulation quilts on the market are cotton felt, non-woven fabric, Oxford cloth, pearl cotton and space cotton, etc. Cotton felt has excellent thermal insulation effect and softness, but it is heavier and easy to deform after long-term use. Non-woven fabric is light and breathable, but the thermal insulation performance is slightly inferior. Oxford cloth is strong and durable, waterproof effect is better, but the cost is higher. Pearl cotton and space cotton are also lightweight and have good thermal insulation, but the price is relatively higher.
✅2. Thermal insulation performance
The main function of thermal insulation quilt is to provide good thermal insulation effect for greenhouses. When choosing thermal insulation quilt, we must first understand its thermal insulation coefficient, thermal resistance value, etc. High-quality thermal insulation quilts should be able to keep the temperature stable in the greenhouse. In addition to the thermal insulation coefficient, it is also necessary to consider the sealing of the quilt, and the thermal insulation quilt should be close to the greenhouse to avoid cold air entering.
✅3. Thickness
The thickness of the insulation quilt also has a direct impact on its insulation effect. Usually, the thicker the quilt, the better the insulation effect, but the thickness is too large may bring inconvenience to use, such as difficulty in rolling and increasing the bearing pressure of the greenhouse structure. Therefore, the selection of thickness should be balanced according to the actual situation of the greenhouse.
✅4. Waterproof and moisture-proof
In the actual use process, the greenhouse often encounters rain, snow and other bad weather, so the waterproof performance of the thermal insulation quilt is also very important. Choosing a quilt with good waterproof performance can prevent rain and snow from penetrating and avoid the loss of insulation effect after absorbing water. In addition to waterproof, moisture is also a factor that needs to be paid attention to when choosing thermal insulation quilts, when choosing quilts, to ensure that its material has good waterproof and moisture-proof function, to avoid affecting the environment in the greenhouse due to weather reasons.
✅5. Size matching
The size of the insulation quilt should match the size of the greenhouse. Too large or too small thermal insulation quilt will affect the ease of installation and thermal insulation effect. When choosing, it is necessary to customize or select standardized quilts according to the actual size of the greenhouse to ensure that the quilt can completely cover the greenhouse and avoid leaving gaps leading to heat loss.
✅6. The weight
The weight of the quilt directly affects the ease of installation and operation. In general, the thicker the insulation quilt, the better the insulation performance, but it also means that the difficulty of operation increases. Therefore, in the selection of quilts, in addition to considering the thermal insulation effect, but also consider the bearing capacity of the greenhouse structure, as well as the bearing capacity of the rolling machine.
✅7. Durability
The thermal insulation quilt of the greenhouse needs long-term use, so its durability is also a factor that cannot be ignored when purchasing. High-quality thermal insulation quilts should have strong anti-aging properties, and can maintain good use status in multiple rolls, exposure to sunlight and wind and rain. Choosing materials with strong wear resistance can extend the service life of thermal insulation quilt.
