With a variety of frame, vent, mullion and transom options for the creation of multiple window styles, the Crown Aluminium 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 the growing demand for this alternative style of window in aluminium in the UK.

Externally, the suite offers 2 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 sight lines.

Internal aesthetic is equally as important, Sapa provides a choice of four aluminium profile styles to suit a wide range of requirements – a traditional aluminium 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 aluminium fenestration range to allow for further flexibility. It is also available in a variety of RAL powder coasted colours and finishes, including single or dual colour options, often in a choice of gloss, matt or satin finishes.

This relatively new Crown Aluminium Suite first launched by Sapa in October 2018 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 in England and Wales.

Hazlemere Commercial also offer the more commercial looking Sapa DF75 Si aluminium window system, which comes with the option of being internally or externally beaded and with the option of casement windows, tilt before turn windows or top swing reversible aluminium windows.
