Putting Guttering On A Polytunnel

It can be fitted to a timber side rail on your new or existing polytunnel.

Putting guttering on a polytunnel.

The gutter is installed at the top of the straight side of the polytunnel hoop where the curve starts. You should now have a strong robust alternative for harvesting rainwater off your polytunnel. 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. Building your own polytunnel from a kit can save you hundreds of pounds in construction costs.

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. 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. 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. I ve tortured myself for a month or more about how i m going to keep the veg in my new tunnel watered from november to may when there s no water on the all.

Choose a warm day to install the cover. Warm weather makes the plastic more pliable and therefore easier to stretch tightly over the frame.
