Two materials, one system
Each material is used where it performs best: timber for internal warmth and aluminium for exterior durability.
Windows
Composite Windows
Timber-aluminium windows combine a warm timber interior with a durable external aluminium layer, bringing together character and low-maintenance protection.
Specified around your project
Warm inside. Durable outside.
Composite construction is often a compelling choice where the comfort and texture of timber belong inside the home, while an aluminium outer face provides a resilient weathering surface. It can also make it easier to coordinate windows and doors across a project.
Key considerations
Why choose composite windows?
Consistent elevations
Coordinated window, door and sliding-door families can create a clear architectural language.
Comfort-led specification
Glazing and frame options are selected against the project’s performance ambitions.
Technical systems
Relevant systems.
