SG7 Strongwood® Security Window – 1155mm Wide × 330mm High
The SG7 is a medium-format Strongwood® Security Window in the 330mm high fanlight range. This is a top-hung opening window — the sash opens outwards from the top — designed for narrow high-mounted openings such as above doors, in bathrooms, or in utility spaces. Solid lengths of steel are encased within each vertical cottage pane bar, and the bars are fixed to the frame — not the sash — so the window remains secure even when open.
Note: At 330mm high, the SG range features vertical bars only — there are no horizontal bars in this height. The vertical steel-cored bars provide the same Strongwood® security specification as the rest of the range.
How the Strongwood® System Works
A standard cottage pane window has timber horizontal and vertical bars on the opening sashes. On a Strongwood® window, the cottage pane bars are fixed to the frame — not the sash. The opening sash is full pane, which means:
-
Easy cleaning – the full pane sash opens freely with no bars obstructing access to the glass
-
Secure when open – the steel-cored bars remain fixed to the frame, so the window is guarded whether open or closed
-
Genuine burglar resistance – solid steel lengths encased inside every timber bar make them extremely difficult to cut or force

Frequently Asked Questions
How does this window open?
The SG7 is a top-hung fanlight — the sash is hinged at the top and opens outwards. This format is ideal for above-door positions, high bathroom openings, and utility spaces.
Why does this window only have vertical bars?
At 330mm high, the window height does not accommodate horizontal bars. The SG range features vertical bars only, each with the same solid steel core as the rest of the Strongwood® range. The security specification is unchanged — only the bar orientation differs.
What hardware is supplied with this window?
The SG7 is supplied with mild steel easy-clean friction hinges and solid brass handles. The top rail includes an integrated weather strip that overlaps the opening sash to prevent water ingress.
What makes a Strongwood® window different from a standard cottage pane window?
On a standard cottage pane window, the horizontal and vertical timber bars are part of the opening sash. On a Strongwood® window, the bars are fixed to the frame and the opening sash is full pane. This means the sash opens freely for easy cleaning, while the steel-cored bars remain in place — keeping the window secure whether it is open or closed.
Is this window secure when open?
Yes — the steel-cored bars are fixed to the frame, not the sash. When the sash is open for ventilation, the bars remain in place across the opening, maintaining full burglar resistance.
Does this window include glass?
No. Glass is excluded and must be sourced and fitted separately by a glazier. Ensure you measure the individual pane openings accurately before ordering glass.
What finish is applied to this window?
The window is supplied unfinished. After installation, apply a quality exterior wood paint, stain, or sealer. Seal all surfaces — including the bottom rail and any end grain — to protect against moisture.
What size is this window?
The SG7 measures 1155mm wide × 330mm high. This medium-format fanlight suits wider above-door and high bathroom openings.
