Why Choose Flush Casement Windows?

Flush aluminium windows are an elegant, durable and energy efficient choice for both heritage and modern property styles. This style of casement window provides a smooth, flat exterior surface that mimics the appearance of traditionally constructed timber or steel framed windows. The result is a sympathetic upgrade to your heritage property, but with many added performance benefits.

Alternatively, our aluminium flush casement windows can also provide a sleek, contemporary look. Thanks to their minimal aesthetic and ultra slim sightlines, our windows are also a popular choice for new build properties.

The AluFold Standard

There’s nothing ‘standard’ about the AluFold Standard. All of our aluminium windows are supplied with high-performance Low-E soft-coat, toughened, double glazed units with a warm edge spacer bar
