Crown Flush Casement

High Performance Windows
The Sapa crown system is a trusted suite of windows and doors developed over the last 10 years with the heritage of the hugely successful and at it’s time industry changing Monarch Aluminium products in mind.. Ticking all the boxes for strength, durability, and appearance. The Crown flush window is ideal for those looking to replace a timber sash window or to replicate traditional building details. Often used in conservation areas. The slim sight lines add extra light into most rooms. A Plus also offer a flush vent which is exclusive to us. If you are looking to mix and match the flush casement complements the 75mm door and window Crown range.

Externally, the suite offers two discreet styles – a traditional flush line mullion and transom or a slim flush line mullion and transom. With the traditional style providing a uniform exterior in keeping with the original flush window profiling is simplified allowing the window vent meeting style to have reduced sightlines as well as the flush appearance. Internal aesthetics are equally as important, so a choice of four profile styles is available. These are a traditional softline vent, contemporary square line vent both of which can be combined with full or step framing as well as full or flat central mullion.
