Cortizo Casement

Cortizo Casement is an aluminum window system

opening outward. It is an attractively priced development of the Spanish Cortizo systems, popular for their modern design, durability and convenient operation. The windows are available with scissor hardware in the swinging (Side Hung) and bottom-tilting (Top Hung) variants.

The standard Slim sash offers narrow, aesthetically pleasing profiles, with the Slim EXT variant glazed from the outside. HD (Heavy Duty – wide) sashes are their larger versions that allow the creation of taller and wider windows, positively influencing the light conditions in the rooms, the aesthetics of the profiles and the arrangement possibilities. The maximum size of an HD window is as much as 1800 x 1800 mm with a sash weight of 100 kg. Also available is the Steel variant that fits into the industrial style. Durability and modern aesthetics of Cortizo Casement window profiles are guaranteed by the process of anodizing and varnishing in all RAL colors. It is possible to use two different colors on the inside and outside of the window.

Our customers’ opinions are the best proof of our quality and commitment to every collaboration.

I recently had new windows installed and the difference is incredible. The rooms feel warmer, and the outside noise has noticeably decreased. The installation team worked efficiently and left everything spotless. Truly a great upgrade for our home.

Sarah P.

We ordered a new front door and couldn’t be happier with the result. It feels solid, secure, and the design perfectly matches the style of our house. The consultation process was clear and professional from start to finish.

David R.

The sliding patio doors we purchased glide effortlessly and let in so much natural light. The quality of the materials is impressive, and the installers were friendly and precise. It instantly made our living space feel more open.

Emily T.

Our new conservatory has quickly become the most used area in our home. It’s bright, cozy, and beautifully constructed. Even during colder days, it stays warm without needing much heating. A wonderful addition to the house.
