As the cornerstone of functionality, polytunnel covers play a major part in providing the internal humidity and microclimate, thus directly influencing the growth and health of the plants housed within. We venture into the world of polytunnel recovering services, examining the various grades and types available, while unpacking linked terms such as UV stabilisation, microns, and gauge sizes, to provide a comprehensive understanding of what each manufactured cover type offers in terms of creating a unique micro-climate.
A Few Types of Polytunnel Covers
These are just a few cover types available from polytunnel recovering services companies.
Clear Film: This type of polythene allows maximum light penetration, creating a bright and warm environment conducive to cultivation growth. It is often chosen for its ability to foster rapid growth in seedlings and young plants.
Diffused Film: By deliberately scattering the sunlight evenly, this film reduces shadows and promotes even light distribution, which encourages uniform plant growth.
Shade Net: Utilised in regions with intense sunlight, these covers help reduce light intensity to green polythene allowing for about 47% shade, thus preventing plant burn and overheating, allowing water penetration.
Reinforced Covers: Usually made up of two thermal material layers, with nylon mesh added for strength and then sealed for better insulation. Takes a lot of hard-wearing, especially on openings, doors, and vents.
Anti-fog and Anti-drip are also available.
UV stabilisation refers to the process of treating and placing a thickness of film onto polythene, using various additives that enhance resistance against the detrimental effects of the sun’s powerful UV rays. They are designed to last longer, with a significant reduction in wear, tear, and brittleness induced by UV rays, reducing the harmful burning effect on plants.
Understanding Microns and Gauges
In the context of polytunnel covers, understanding the terms "microns" and "gauge" is crucial, especially if you require a quality-produced cover for professional growing purposes. A polytunnel recovering services company can supply you with advice and a quote for supply only and delivery costings, or for, supply and fitting.
Microns: Refers to the thickness of the polytunnel film, with one micron equal to one-thousandth of a millimetre A higher micron count indicates a thicker, and consequently more durable film placed onto the cover during the manufacturing process. Typically, commercial polytunnels employ films that are 150-200 microns thick.
Gauge: This is another unit to measure the thickness of the polythene, where a higher gauge denotes a greater thickness level. It provides an insight into the durability and strength of the cover type,720-gauge is the minimum grade, up to 1200-gauge used by professional growers.
Check Out the Type of Cover Before Buying.
The range of professional polytunnel covers available in various grades and types, brings forth the promise of nurturing distinct related micro-climates, that cater to a wide array of horticultural and agricultural needs. Understanding their known protective shield offered by them being UV stabilised, to the thickness denoted by microns and gauge thickness, each aspect carries a relevant signature of strength and durability.
As one navigates through the offerings of clear to diffused polythene films, and the protective embrace of shade netting, it becomes evident that the choice of the type of polytunnel covers required for your intended plants, crops, or flowers is a decisive factor, in creating an ideal and thriving and nurturing environment. Always receive several quotes, from polytunnel recovering services companies.
