A polythene cloche is a mini polytunnel which is used to retain heat and protect your plants from rain and late frost.
Premier Polytunnels Tip! A polythene cloche is ideal for 'double glazing' your polytunnel. Using a polythene cloche inside your polytunnel during the colder months gives your plants extra protection from the cold British winters, keeping the frost off your crops and saving on heating costs.
The polythene used for our polythene cloches is a clear, 480 gauge/120 micron polythene film - four times thicker and stronger than a cloche or dust film - with a 2-year warranty against UV degradation.
Our cloche hoops are made using 28mm diameter Z35 high tensile galvanised steel, which will last for years. Timber base rails are pressure treated with a wood preserver to protect against rot and the cover is fixed simply by using timber battens and nails.
Our Premier Polythene Cloches are 4ft wide and 3ft 7in high, making them ideal for using on raised beds. Supplied with 2 extension legs to allow for quick access and ventilation.
