Polytunnel doors and cold weather.

Camile · Polytunnel doors and cold weather.

Hi everyone,

I was wonderring what I could do to lower the heat loss in the polytunnel.

So far the doors are about 2/3 polythen (bottom) and 1/3 windbreak mesh (top) ..

I'm keeping the doors closed at all time otherwise the birds would wreck it all ..

I thought there was some sort of polythen blind coming with the doors, but it doesn't, so I was wonderring if I should make some sort of blind, or polythen panel to cover the top part of the part for those long winter nights ?

I intend to leave some barrels with water in it so the diference in temperature won't be too big but that may not be enough, just a p lus me think..

Thanks,
Camile

I think the toss-up is between retaining heat and maintaining sufficient airflow to minimise the mould which flourishes if it is too humid . I would have expected them to supply something to go over the mesh on cold nights but it might be worth checking with the supplier in case it is a special design feature -- high tech osmotic midge-catching net or something !
