High-Performance 88.4mm System · Up to 62mm Insulated Glass
AMJ 88T Tilt & Turn Window is the high-performance option in the AMJ tilt-and-turn range, designed for projects that require deeper thermal breaks, triple glazing and larger sash capacity. For tilt and turn windows USA projects, the 88T is particularly suited to cold-climate homes, luxury apartments and energy-focused construction while retaining the familiar tilt-and-turn opening function.
Its 88.4mm frame depth, 44mm thermal break strip, and standard triple-glazed construction are designed for projects with demanding energy and glass specifications. The system supports insulated glass units up to 62mm, providing substantially more glass capacity than the 67T and 78T models.
Standard glazing uses a three-pane Low-E insulated glass unit with two argon-filled cavities. With an estimated U-value of ≥1.2 W/m²·K, the 88T is recommended for high-end houses, luxury apartments, cold-climate projects, hotels, and energy-efficient developments.
The AMJ 88T Tilt & Turn Window is the premium high-performance option in the AMJ tilt and turn window range.
Compared with the 67T and 78T systems, the 88T is built for thicker glass packages, stronger energy performance, and higher-specification building projects.
Choose 88T when the project needs premium glass capacity, triple glazing, stronger insulation, and higher energy performance.
