Hi Julie
The main reason for the greenhouse choice was that it gives 100% light transmission which stops seedlings going
“leggy”. Twin glazed polycarbonate and the cheaper range of of green coloured poly tunnels don’t appear to have 100% light.
Another consideration was possible vandalism on the allotment site. Polycarbonate is virtually indestructible.
I agree that £300+ is not really cheap. There were many second hand ,even free, houses and tunnels on eBay , preloved and such web sites. However all had “buyer to dismantle and collect” as a condition and always seemed to be 300 miles away
I decided to bite the bullet and spend the money.Two easily handled packages arrived at the front door .Easily got to the site in car and on roof rack and being new had a guarantee.
I am considering sealing the glazing panels to the frame but it seems a fiddly job and would need a lot of sealer. I don’t think the noise would be much reduced as most of the noise appears to be produced by the panels flexing rather than rattling in the frame.
Good Luck
