Crown Flush Window suite to suit all residential applications | Sapa

With a variety of frame, vent, mullion and transom options for the creation of multiple window styles, the Crown Window Suite now offers even greater design flexibility.

With a consistent unbroken external appearance, the flexibility of Sapa’s new aluminium flush window will suit a wide range of residential applications - from classic cottage aesthetics to modern, sleek designs. Sapa has developed the Crown Flush Suite to address a range of customer preferences and provide solutions without compromise.

Externally, the suite offers two discreet styles - a traditional flush line mullion and transom, providing a uniform exterior face in keeping with the original flush window, or a slim flush line mullion and transom. This has simplified profiling which allows the window vent meeting style to have a flush appearance and reduced sightlines.

Internal aesthetic is equally as important, Sapa provides a choice of four profile styles to suit a wide range of requirements - a traditional softline vent or contemporary square line vent, combined with full or step framing as well as a flat or full central mullion.

The new suite benefits from full compatibility with the existing Crown range to allow for further flexibility. It is also available in a variety of colours and finishes, including single or dual colour options.

The Crown Suite offers excellent weather performance with a Class 9A water tightness rating, Class 3 air permeability and Class B5 wind resistance. In regard to its thermal performance, the suite is Window Energy Rated and delivers U-values compliant to part L of the Building Regulations.

Crispin Jedrzejewski, Technical Manager at Sapa Building System said: “The inclusion of this suite not only broadens our offering, but it is also an industry first – successfully replicating the look of traditional cottage window frames with aluminium. The aesthetic is key – with this suite the homeowner can combine a historical external profile with a contemporary internal one, or vice versa, allowing for numerous applications and combinations.”
