TW85
Super Thermally Insulated Window

TW85 Super Thermally Insulated
Casement Window

The TW85 is an elite, super thermally insulated inward-opening window system engineered with an 85mm basic frame depth to meet the ultra-stringent requirements of Passive House standards. Designed as the ultimate climate barrier for luxury residential envelopes, the TW85 combines heavy-duty structural integrity with cutting-edge thermal engineering.

At its core, the system utilizes multi-cavity, continuous polyamide thermal breaks integrated with advanced insulating foam inserts to completely eliminate structural thermal bridging. The TW85 represents the pinnacle of premium acoustic isolation, airtight sandstorm defenses, and uncompromised human comfort.

TW85 Features
Technical Overview

Key Features & Technical Benefits

Super Thermal-Break Technology: Employs wide, multi-cavity thermal insulation barriers packed with high-density polyolefin foam inserts to block radiant and conductive heat transfer.

Monumental Glazing Capacity: Effortlessly accommodates heavy triple or quadruple-glazed insulated glass units (IGUs) up to 60mm thick, allowing for the integration of thick acoustic laminates and high-performance Low-E coatings.

Advanced Multi-Point Inward Operation: Supports versatile, heavy-duty inward opening configurations—including traditional side-hung, high-ventilation Turn/Tilt, and Tilt-Before-Turn layouts.

Micro-Dust & Air-Tightness Mastery: Formulated with a three-layer, continuous EPDM gasket matrix featuring a solid center gasket, achieving European standard Class 4 Air Tightness.
