Polytunnels and the Various Coverings That Are Readily Available

Polytunnel suppliers understand the importance of selling different new and replacement polytunnel coverings. The variety in polytunnel covers, made from different thicknesses of plastic materials and applied UV stabilised film, plays a defined role in their protective effectiveness and the related micro-climate they provide to plants, flowers crops and other uses and purposes they are intended for, apart from cultivation. These safeguarding and creative climate features are particularly important for professional growers who require consistent and high-quality yields throughout the year, from the various crops that can be grown seasonally or throughout the year.​

Differently Manufactured and Graded Polytunnel Covers

The range of colours and grades of polytunnel covers and quality manufactured replacement polytunnel coverings to suit various crop types and different uses or purposes they are now used for in farming, niche cultivation, as business canopies or storage and animal shelters, they provide strong protection for different climatic conditions, thicker insulated coverings enhance heat and warmth retention for cultivation and other needs they are put to.​

A)   Standard polytunnel covers, available in coloured or clear translucent materials in a thickness grade, that creates a specific microclimate within the tunnel. These coverings are normally related to smaller and medium-sized builds when placed in a garden setting or an environment of protection from walls, bushes, trees or fencing, their covering is more protected than if out in an open area or field, helping improve protection and a response to better plant growth and health, compared to unprotected environments.​

B)   Thermal anti-fog or drip covers are thicker and applied with film additives to reduce condensation, these coverings help reduce the risk of fungal diseases and mould, ensuring a healthier growing environment with less condensation build-up dripping onto crops and causing problems.​

C)   Opaque or Diffused covers disperse sunlight more evenly, reducing shadows and ensuring a uniform distribution of light, which is beneficial for consistent plant growth whilst keeping temperatures stable.​

D)   Coloured covers are used to shade different crop types that require warmth and shade but not too much direct heat and sunlight.

E)   Heavy-duty thicker layered or insulated coverings are purposely manufactured for year-round cultivation, in colder climes around the UK, these robust more durable covers provide enhanced insulation and stable temperature warmth, during colder seasonal months.​

New and Replacement Polytunnel Coverings

The selection of the appropriate cover material is vital for creating optimal growing conditions, directly influencing crop health and yield.​ While standard polytunnel covers depend on their quality of thickness grade and UV film are awarded a life expectancy of between 4 to 6 years, other more durable, thicker layered and insulated ones, will last 6 to 8 plus years with proper care and when degraded over time replacement covering is required.

Good airflow and ventilation regulate temperature, humidity, and carbon dioxide levels.​ Effective and efficient ventilation reduces problems or issues of overheating, maintaining an amiable temperature, conducive to healthy plant and crop growth.​Helping photosynthesis to successfully take place.

Ventilation methods include manual or automated systems, such as roll-up side panels, louvred vents, and extraction fans, tailored to the specific needs of the crops and the scale of the operation.​

Operators engaged in large-scale production and year-round production are more likely to require replacement polytunnel coverings or use different covers to suit seasonal crop growing, they require more robust structures with advanced environmental controls to ensure consistent crop quality and meet market demands and thicker more durable coverings when placed over expansive frames.​

Conclusion

The variety in polytunnel covers, whether new or replacement polytunnel coverings are vital for commercial and individual growers, allowing them high-quality choices of different cover types and an attached manufacturer's life expectancy guarantee, defined by their thickness and grade.
