Heavy duty clear polythene (250 micron) – Thick heavy duty plastic sheeting perfect for heavy duty applications such as a damp proof membrane, for mixing cement, temporary roof covering, temporary window repairs, industrial protection, weather protection and for heavier duty wrapping for storage and transit. According to size we supply the polythene in either a sheet form or a roll. The polythene is great for use in the greenhouse as a flooring or temporary window, and for all sorts of jobs in the garden. The plastic, being heavy duty and durable, can also be used as mattress protection sheeting. Being strong polythene, it is much more resistant, than standard plastic, to rips, tears, weather damage and punctures.
