Cortizo Casement

Cortizo Casement is an outward-opening aluminium window system. It is an attractively priced development of the Spanish Cortizo range, valued for its modern design, durability and convenient operation. The windows are available with scissor fittings in Side Hung and Top Hung versions.

The standard Slim sash offers narrow, attractive profiles, while Slim EXT is glazed from the outside. HD (Heavy Duty) sashes enable taller and wider windows and a Steel variant is available for industrial-style projects.

The anodising process gives the profiles strength and a modern visual finish. Two different colours can be used on the inside and outside of the window.
