Building your own polytunnel from a kit can save you hundreds of pounds in construction costs.
Tape the gutters in a v shape above a barrel with the ends.
Coloured tape blocks light and heats up in the sun shortening the life of your plastic.
Warm weather makes the plastic more pliable and therefore easier to stretch tightly over the frame.
It can be fitted to a timber side rail on your new or existing 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.
Clean the plastic well and use transparent tunnel repair tape.
The gutter is installed at the top of the straight side of the polytunnel hoop where the curve starts.
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.
Our polytunnel gutters are long lasting aesthetically pleasing and require no maintenance other than clearing them of debris occasionally.
Choose a warm day to install the cover.
They are shaped like a little gutter if you turn them upside down and are much cheaper than commercial polytunnel gutter kits.
