An innovative window system for your next installation

Our top-tier uPVC casement windows are manufactured using Modus, the market leading profile system from Eurocell. Our Modus uPVC casement windows are available in three distinct sash styles to suit any property: Standard sash, Slim rebate sash and Flush sash.

Slim rebate sash casement windows offer clean sightlines, an internally flush finish and external slim rebate, creating high-end contemporary finishes. Flush sash casement windows benefit from an internal and external flush sash, offering enhanced aesthetics to rival timber windows, with superior thermal performance.

Modus uPVC casement windows are a high-performance alternative to timber windows, delivering stunning contemporary looks or charming traditional aesthetics with low maintenance, durable uPVC frames. Offering exceptional security features, Modus casement windows are extremely secure, featuring a multi-chamber profile with internal beading that enhances the inherent strength of the uPVC frames and prevents warping under extreme pressure.

Built-in sustainability

Modus UPVC Casement Windows

Modus uPVC casement windows offer customers built-in sustainability, as the Modus system utilises 50% post-consumer recycled uPVC as standard. Additionally, innovative dual material extrusion technology ensures efficient use of the post-consumer recycled material within the production process. Impressively, Modus is manufactured and recycled in a state-of-the-art plant in Derbyshire, offering a lower carbon footprint than many rival profile systems that are manufactured outside of the UK.

Modus uPVC casement windows are constructed with sustainable dual material extrusion technology, which places the concentrated post-consumer recycled material into the centre of the frames, whilst new ‘virgin’ uPVC is used for the exterior edges and surfaces, ensuring there is no compromise to the quality of the window’s finish.
