Film for greenhouses - how to choose by quality, material of manufacture, number of layers, thickness and cost

Varied in properties and characteristics (thick or thin, colored or transparent), a polymer film for greenhouses is an affordable option that helps to collect an early crop from the beds. The film for the greenhouse is different. Gardeners are attracted by the ease of installation of film greenhouses, low cost and the ability to choose.

Types of films for greenhouses

The number of types of popular material is extremely large. When planning to buy a greenhouse film, pay attention to the following:

  • frame design;
  • Operating conditions.

Polyethylene

Ordinary polyethylene quickly deteriorates due to ultraviolet radiation, the integrity of the material is violated. But such a product is inexpensive, for example:

How to choose a film for greenhouses

When choosing which film is best for the greenhouse, you should pay attention to the following characteristics of the covering materials:

  1. Strength - under the gusts of wind, poor-quality material will quickly burst.
  2. Durability - the best performance for stabilized photo-resistant coatings.
  3. Web width - affects the number of joints, increasing the complexity of the work.

Reviews

Anna, 52 years old My husband and I have been choosing for a long time what kind of greenhouse film we need. We decided to try reinforced. The purchase paid off. She served us for four whole years. This is much longer than regular polyethylene, which was before. Reinforced coating lasted in the heat and frost. The price is high, but we took a discount on the stock.
Sergey, 60 years Six years ago, I decided to buy a film for a greenhouse, I took PVC for a test, because the sale was in the store. The following year, she closed it and a small greenhouse on a wooden frame. It's been 5 years now. I don’t take off for the winter, I cover it with cloth full of frost. I distributed the remnants of the roll to relatives and neighbors in the country, everyone appreciated it positively.
Olga, 43 years old. I just decide which and where to buy a film for a greenhouse on a metal frame. Our greenhouse is closed with yellow light stabilized. Three years have passed, everything is in order. I shoot carefully for the winter. I am more inclined to the proven option, but I think I order by mail: there is delivery, and cheap, compared to the nearest stores.
