uPVC casement windows are the most chosen window style in the UK, they offer slim sightlines which allows for maximum light entry & unimpeded views, they successfully combine traditional aesthetics with the perks of modern energy-efficient windows.

These differ slightly to standard casement windows, the sash (the opening part of the window) sits flat (flush) with the surrounding frame creating a smooth finish to mimic traditional timber windows.

The same classic style as casement windows, these windows are designed so that they don’t require a central mullion (upright) resulting in uninterrupted views when windows are opened.
