The Ultimate Evolution, aluminium bi-folding door from Sliders UK brings cutting-edge innovation to aluminium bi-fold door design.

With ultra slim sightlines – even compared to the standards set by other leading aluminium systems – it’s a bi- folding door that comes with end-user appeal and high margin ‘engineered-in’.
