Er hum! Cough, cough.have you tried thomas and Fontaine - secure covers windbreaks?
available through Wynnstay but you can go direct
perhaps its the way the shed builders put them up then but the webbing just looks slack as all they seem to do is pull the straps tight through the sleeves,we've a gale breaker thats been on cubicle shed now for 17 years and is as good as the day it went up?
We have them on front of hay barns and stock sheds and when tightened properly are tight as a drum. At least get don’t shred in the wind after 5 years
