Polythene & Netting Covers
Due to its clarity, clear polythene allows around 2% more light to enter your polytunnel than with a diffused polythene cover. This extra light brings extra heat which can be a benefit during the early and late months of the growing season. Especially popular in northern and western regions where lower light levels naturally occur.
Lumisol Clear transmits up to 92% of light. In the UK where light levels can be lower, clear polythene allows more light to enter which in turn can bring picking time forward. Lumisol Clear manipulates the type and level of light entering the greenhouse to significantly improve crop hardiness, colour, taste and shelf-life.
Lumisol Clear is a UV ’open’ polythene film, allowing UV light to reach your plants. This can have many benefits for both edible and ornamental crops, such as enhancing the fragrance, taste, colour, earlier harvesting and longer post-harvest shelf life.
In addition, UV open films promote plant anti-oxidants which are good for plant health and encourage stronger plants. Contains an anti-condensation additive, making it able to control condensation on the underside of the film.
Comes with a 7-year guarantee, although a 12-14 year lifespan is not uncommon.
Light transmission: Up to 92%
Thermic effect: Over 80%
Diffusion: Less than 35%
Lumisol Diffused is a UV ’open’ polythene film, allowing UV light to reach your plants. This can have many benefits for both edible and ornamental crops. Thanks to it's unique anti-condensation additive, Lumisol Diffused is able to control condensation on the underside of the film.
Light-diffusing polythene films scatter the light as it passes through the polythene. This enables the light to penetrate deep in to the plant canopy, as it hits the plant from all directions, not just from the direction of the sun. This ‘diffused’ light reduces the higher foliage from shading the lower parts of the plant. Light diffusing films allow more light in to your polytunnel when the sun is low in the sky (early or late in the day, and also during the short days of winter). The diffusing process deflects more light downwards in to the crop, rather than being reflected upwards as happens with glass and clear polythene.
Lumisol Diffused can reduce mid-day summertime temperatures by 2-4°C Anti-Drip (condensation reduction).
Thanks to its unique additive, Lumisol® is able to control the condensation of water on the underside of the tunnel cover. Providing the film is correctly fitted, water will condense uniformly as a very thin layer, which, instead of remaining in position as droplets, runs down the sheet. This reduces the risk of water dripping on to the plants below and prevents the loss of light caused by these droplets, which can amount for as much as 15% light reduction. The effectiveness is reduced over the life of the cover, but an anti-condensation solution (Sunclear©) can be re-applied with a sprayer after several years if required.

Green/White Polythene (Blackout)
Green & white polythene is especially formulated to meet the needs of the mushroom grower. The green outer layer helps this cover blend in with the environment, whilst the white layer reflects internal lighting to provide a pleasant working environment. A black core layer ensures complete opacity (black-out) and contributes to the durability of the film.
This film is also used for other applications, such as livestock housing, fish farms and protective structures. As this polythene is black-out, artificial lighting will be required.
Light transmission: 0%
Thickness: 800g (200mu)
Diffusion: N/A - Blackout
White UVI Polythene
White UVI polythene produces shade and reduces daytime temperatures, allowing 60-70% light transmission.
A thermic film developed to help keep the growing environment warmer by reducing the heat lost through long wavelength infra-red radiation. Higher overnight temperatures encourage plant growth, can reduce plant losses and allow savings to be made on heating.
Ideal for: Crops that require shade and cooler daytime tempera tures such as nursery stock, ferns and conifers. The over-wintering of hardy shrubs and for general hardening off. Also widely used in the agriculture for general livestock housing and also general stor age.
Light transmission: 60% - 70%
Thickness: 720g (180mu)
Thermic effect: 55%
Diffusion: 32% - 33%
Full Net Covers
Our in-house fabrication department can produce net covers to any size. Our standard shade net covers are dark green with a 40%-45% shade value, but heavier shade values can be catered for.
Our production method spaces the seams between 2m-3m apart (depending on the size), with the seams running parallel with the hoops (width-ways). Bespoke nets can be supplied which can include hemming and eyelets.
Any size can be fabricated. Email email@example.com or call 01282 873120 for details.
