The TW75 thermally insulated casement window is a high-performance, 75mm-deep thermally insulated window system engineered for advanced building envelopes. Designed for ultimate flexibility, it accommodates inward-opening, turn/tilt, tilt-before-turn, and symmetrical double-vent configurations.
A core comfort feature is its massive 56mm glazing capacity, which easily houses heavy-duty triple glazing or acoustic laminates to isolate interiors from intense outdoor noise. Boasting a sleek 107mm total face width and an outstanding Uw value of 1.5W/(m²·K), the TW75 delivers peak energy efficiency and premium acoustic comfort.
Versatile Opening Matrix: Fully adaptable for multiple operational configurations, including traditional inward-opening, high-ventilation turn/tilt, tilt-before-turn, and double-vent systems.
Deep 55mm Glazing Capacity: Effortlessly accommodates heavy-duty triple-glazed units or advanced acoustic glass combinations for maximum climate control and sound attenuation.
Exceptional Thermal Insulation: Delivers an impressive Uw 1.5W/(m²·K) baseline rating, mitigating radiant heat transfer to keep energy consumption low.
Uncompromised Cost-Efficiency: Achieves strict international energy compliance parameters without forcing specifiers into expensive, hyper-custom sealed glass makeups.
