The superior choice for window innovation

Infinity PVCu windows feature a stylish smooth corner weld. This is achieved by pushing the leftover plastic into the profile to create a perfectly smooth, timber effect corner joint. They are the perfect choice for period property renovations but are equally suited to adding charm and character to contemporary properties. Infinity PVCu windows can be specified in a range of different styles. Choose from flush sash, standard casement, and fully reversible windows depending on your project specifications.
