If you have a shed that you would like to ventilate I have a few louvres that have been made to the wrong size for one of our customers.
Instead of throwing them away I thought I'd offer them to the good folk of SA Footy first at an excellent rate.
Basically cut a hole in your shed and fit off the louvre to give yourself some natural ventilation. The louvre has vermin mesh to stop birds/vermin entering through the penetration.
PM me for pics and sizing.
