Aluminium Windows

RT 72 Aluminium Open-in Window

The RT 72 Aluminium Window System combines strong thermal performance, slim profiles and broad design flexibility in one modular platform. With patented Reflex thermal technology, multiple insulation levels, concealed drainage and a choice of contemporary or renovation-inspired aesthetics, RT 72 is designed to support both performance-led and design-led specifications.

  • High thermal performance – with system variants (RT 72 HI, I+ and I) delivering window performance from Uw 0.94 W/m²K depending on specification, size and glazing build-up.
  • Patented Reflex thermal technology – a specialist thermal break solution designed to improve insulation performance efficiently across the system.
  • Broad design flexibility – available in a wide range of configurations and design styles.

Thermal

The RT 72 Aluminium Window System is available in a range of thermal performance levels to suit differing project requirements.

Depending on configuration, glazing specification and size, the system can achieve Uw values from 0.94 W/m²K to 1.1 W/m²K.

Its 35 mm thermal isolator incorporates patented Reflex technology to help deliver enhanced insulation performance.

Weathering

Tested for strong weathertightness, achieving Air Permeability Class 4 and watertightness 9A +1650 pa. Weather performance comes at no expense to external appearance while maintaining effective system performance.

Security

The system has been tested to PAS24 and RC2 supporting secure specification across a range of building applications.

Design Felxibility

The modular RT 72 platform supports fixed glazing as well as inward- or outward-opening window applications, giving designers flexibility across façade types and project demands.

A broad choice of styling options is available.

Glazing and Fabrication Options

The system features a 72 mm frame depth and 80 mm vent depth, with glazing capacities up to 56 mm in the frame and 64 mm in the vent, depending on configuration.

It supports both internal and external glazing, with compatible hardware options.

Safe and Sustainable

Cradle to Cradle certification

The RT 72 Aluminium Window System is a versatile, thermally broken solution designed to deliver strong thermal performance, slim sightlines and broad design flexibility across a wide range of project types. Developed around Kawneer’s patented Reflex technology, RT 72 combines high levels of insulation with refined aesthetics, helping specifiers achieve comfort, performance and architectural freedom in a single system.
