• Heritage Style with Cutting-Edge Performance

    Flush Look Windows

    Offer your customers the traditional aesthetics of timber flush casement with the benefits of modern materials. Inspired by classic timber casement designs, our flush aluminium windows feature opening sashes that sit perfectly level with the outer frame, creating clean sightlines and a heritage-inspired aesthetic that is well-suited to both period properties and contemporary builds.

Lasting Beauty

Secure as Standard

Our flush aluminium windows offer exceptional longevity, with corrosion and rust resistance that ensures decades of reliable service. The versatile flush profile system adapts beautifully to both residential and light commercial projects, equally capable of creating traditional casement windows with timber-inspired elegance or striking contemporary designs for modern applications.

 

The Perfect Colour Palette

Find the perfect colour for your project with our extensive colour palette, comprising more than 200 RAL options and available in both matt and gloss finishes. For distinctive projects, we offer dual-colour configurations with different finishes inside and out.

Our premium finish options include sophisticated metallic coatings, textured surfaces, and anodised-effect treatments, all applied using high-quality polyester powder coating technology renowned for its fade and flake resistance.

 

Excellent Energy Efficiency & Ventilation

Our flush windows are designed with advanced thermal technology in mind, with innovative polyamide thermal breaks creating an effective barrier between external and internal temperatures. This engineering significantly reduces heat transfer and improves overall thermal performance, with energy ratings available up to grade A.

For discreet ventilation, integrated concealed night vents maintain the windows’ sleek appearance without compromising airflow.
