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

The standard Slim sash offers narrow, aesthetically attractive profiles, with the Slim EXT variant glazed from the outside. The HD (Heavy Duty - wide) sashes are their grander variation that enables the creation of taller and wider windows. Their size positively influences the amount of light reaching the interiors, the aesthetics of the profiles and the design possibilities. The maximum dimensions of an HD window are as much as 1800 x 1800 mm with a sash weight of 100 kg. A Steel variant is also available to match the industrial style.

The anodising process provides the profiles of Cortizo casement windows with their strength and modern visuals. They are available in all RAL colours. It is possible to apply two different colours on the inside and outside of the window.

*The above value of Uw is given for a reference window with dimensions of 900 x 1200 mm, in the best thermal variant.
