Weston Range Shutters fitted in St Josephs, Clonsilla, Dublin 15. Why shutters over blinds? Shutters have a longer life span on average. Shutters tend to last around 30 years from the day they are first installed. Most blinds tend to have a shorter life span, mostly around 5-10 years before you may see time taking its toll on the shape and colour. Shutters have become the latest thing that everybody wants. This trend came from the other side of the pond and it looks like it’s here to stay for a good while.
