To ensure rainwater runs directly into the gutter a series of timber battens we used 19mm x 38mm pressure treated battens may be required to close off any gaps between the guttering and the side rail.
Putting guttering on a polytunnel.
Or if you don t have a timber side rail and your polythene is trenched or fixed to a base rail we supply an extruded aluminium backing profile.
The gutter is installed at the top of the straight side of the polytunnel hoop where the curve starts.
Choose a warm day to install the cover.
All you need are some basic diy skills and some willing helpers four people is ideal.
It can be fitted to a timber side rail on your new or existing polytunnel.
Warm weather makes the plastic more pliable and therefore easier to stretch tightly over the frame.
Make sure that you have a drop of an inch or two at the end where the water is going to go so that the guttering can be lined up with it.
You should now have a strong robust alternative for harvesting rainwater off your polytunnel.
Not many solutions are available to collect rain water fr.
To have something to mount the gutter to i fixed a 2 x 1 batton all the way down one side before i put the polythene cover on.
