How can I choose the best cloth of greenhouse shades?
The most important features that need to be found in a greenhouse shade are the shadow percentage, the ultraviolet (UV) protection and color level. There are two types of greenhouse shades: a standard shade and alumitex cloth, and it is important to consider the elements of everyone before purchasing. The design of the shadow fabric and whether it is knit or woven will also have to be considered.
The percentage of shade you decide to buy is its most important feature. The densities differ from 22% to 90% and the type of plants you grow dictates the density you need. It is also important to choose a greenhouse shade with a high level of UV protection.
The standard shade cloth is made of UV protected polyethylene, which comes in woven and knit varieties. If you need to fit, it is best to choose a knitted variety because the woven type will be frayed after the cut. Adaptation is sometimes necessary for custom greenhouse or for naming air openings.
This type of clothThe shade comes in different colors, but black seems to be the most common. The black fabric shade absorbs heat and protects against harmful UV rays, but may also cause temperature rising by transferring heat and holding inside the greenhouse. The white greenhouse shade reflects and distracts solar heat and UV rays. It does not hold heat and lowers the temperature of the greenhouse.
Alumitex is the second type of shade of greenhouse shade and can be used inside the greenhouse because it is so light. It is more expensive, but its aluminum fibers are very effective in reflecting heat and harmful UV rays. This type of shadow cloth is woven and will be frayed after cutting, so it will be necessary to record it.
The size of the shade you need is also considered. Some sellers only sell standard widths, but some offer a tailored shadow cloth. If you choose to have a shadow on your own cut, it is good to look for a supplier whoThe rider will also strengthen, strengthen and insert bushings.
The type and type of passages used is another consideration. The bushings are plastic or brass rings that are inserted along the edge of the greenhouse shade to easily secure. It is recommended a gap of 2 feet (about 0.60 m) between the bushings, but in an area with a high wind, they should be about 1 foot (about 0.3 m).
