A fresh look for a traditional home. We replaced rotten timber box sash windows with Roseview Charisma uPVC sliding sash windows in Chartwell Green.
The result brings improved thermal efficiency, high security and lower maintenance, together with a noticeable lift in kerb appeal.

Before & after
The original timber windows had deteriorated, with weathered frames and peeling paint detracting from the front of the property. Replacing them was an opportunity to improve everyday comfort and security while keeping the familiar sliding sash appearance.
The new Roseview Charisma windows retain the tall proportions and traditional glazing-bar detail that suit this red-brick home. The soft Chartwell Green finish sits alongside the existing darker green exterior details, giving the frontage a coordinated and refreshed appearance.
The before-and-after photograph shows how much difference the window replacement makes to the overall look of the property.

Everyday improvements
The replacement windows offer better thermal performance than the old deteriorated timber windows, helping make the home more comfortable.
Key-operated acorn sash locks secure the windows when closed, combining practical everyday security with traditional-looking furniture. The interior photograph shows the paired locks fitted at the meeting rail.
The uPVC frames reduce the upkeep associated with ageing timber. Routine cleaning replaces the regular sanding and repainting needed to maintain painted timber window frames.
Security in more detail
Security was an important part of replacing the deteriorated timber windows at this Brightlingsea home. Roseview Charisma uses traditional-looking acorn furniture with key-operated sash locks, keeping the familiar appearance of a box sash window while providing a positive locking action.
The locks are positioned at the meeting rail, where the upper and lower sashes meet. With both sashes fully closed, the catches engage and can be locked using the key. This secures the sliding sashes in their closed position.
The interior window pictured in this project has two sash locks spaced across the meeting rail. These provide two points of engagement while keeping the hardware discreet and in keeping with the window's traditional styling.
For new quotations, Charisma Rose is also available with an optional enhanced security specification, including Secured by Design. Ask our team to include your security requirements when preparing your quote so the appropriate specification can be confirmed.

The exterior colour adds character to the brick frontage, while the white internal finish keeps the window looking bright from within the room. These photographs show the glazing-bar layout, sliding sash design and completed installation in more detail.
