WHY CHOOSE POLYTHENE OR PLASTIC FILM CLAD GREENHOUSES?
In a world of rapidly changing markets, pressures of ever increasing competition, trends in health and safety, and speed of technological change, the case for plastic clad greenhouses has never been stronger. A commercial polytunnel greenhouse purchased today from Clovis Lande is as reliable as a glass clad structure. The cost of replacement plastic cladding every 5 years compares favourably with the maintenance cost of glass. Development of innovative claddings never stops. Plastics are available which incorporate additives which selectively block or enhance certain wavelengths, improve growth rates, inhibit certain diseases, and enable correspondingly reduced use of chemicals. Since plastic cladding has to be changed every 4 to 5 years, it is easy to keep up with technical advances. Conversely, there are inbuilt problems of cost for users of glass. Existing high investment entry costs for glass structures will increase still further if gantry systems, advocated by the Health & Safety
