Slim Sightlines
Incredible Durability
Weather Resistance
Designed for architectural elegance and cutting-edge performance, our aluminium systems set the standard for high-end glazing.
Featuring a high-performance polyamide thermal break, our aluminium frames prevent heat loss, achieving a superb window transmittance from $1.0\ \text{W/m}^2\text{K}$ as outlined in the Cortizo-Aluminium-Window-Casement-System-Brochure_5.pdf.
Block out external disturbances and enjoy total tranquility. Our advanced glazing combinations offer exceptional noise protection, achieving up to $45\ \text{dB}$ in acoustic reduction.
Tested under extreme conditions, our casement system achieved Class E1200 water tightness. Over a $75\ \text{minute}$ test with a total deluge of $450\ \text{liters}$ and wind speeds of $161\ \text{km/h}$, there was zero water penetration.
Make a bold statement with our extensive range of colours and high-durability finishes. From classical black and textured anthracite to custom RAL shades or wood effects, our marine-grade polyester powder-coated finishes are designed to last. We also offer dual-colour frames so you can match your exterior brickwork and interior decor simultaneously.
