SE4 Strongwood® Security Window – 1710mm Wide × 635mm High
The SE4 is a wide-format Strongwood® Security Window in the 635mm high range. This is a top-hung opening window — the sash opens outwards from the top — making it ideal for high-mounted openings such as bathroom and toilet windows where privacy and ventilation are both required. Solid lengths of steel are encased within each cottage pane bar, and the bars are fixed to the frame — not the sash — so the window remains secure even when open.
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 SE4 is a top-hung window — the sash is hinged at the top and opens outwards. This makes it well suited to high-mounted positions such as bathroom and toilet windows, where you want ventilation without compromising privacy or security.
What hardware is supplied with this window?
The SE4 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 SE4 measures 1710mm wide × 635mm high. This wide format suits larger bathroom, utility, and bedroom openings requiring a top-hung window.
