    Glazing

    High performing glazing options to maximise performance

    All Midori Aluminium casement windows are fitted with high-performing double glazing. With glazing thicknesses of either 24mm or 40mm, our casement windows can be designed to suit your needs. Because of the inherent strength of our aluminium frames, large expanses of glass can be easily supported. This allows for super slim sightlines to optimise natural light.
