SD5229 Strongwood® Security Window – 2820mm Wide × 1490mm High
The SD5229 is a large-format Strongwood® Security Window that delivers genuine burglar resistance without sacrificing ventilation or ease of cleaning. 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. Built from quality timber in the classic cottage pane style, this window suits both traditional and contemporary South African homes.
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 in the way
-
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
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.
What makes a Strongwood® window more secure than a standard timber window?
Strongwood® windows have solid lengths of steel encased inside each cottage pane bar. Standard timber bars can be cut or forced. The steel core in Strongwood® bars makes them extremely difficult to compromise. Because the bars are fixed to the frame rather than the sash, they cannot be bypassed by simply opening the window.
Is this window secure when open?
Yes — this is one of the defining advantages of the Strongwood® system. 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.
Is this window easy to clean?
Yes. Because the opening sash is full pane (the bars are on the frame, not the sash), the glass is fully accessible when the window is open — making cleaning straightforward compared to a standard cottage pane window where bars obstruct the sash.
What hardware is supplied with this window?
The SD5229 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.
Does this window include glass?
No. Glass is excluded and must be sourced and fitted separately by a glazier. This is standard for South African timber windows. Ensure you measure the individual pane openings accurately before ordering glass.
Which direction does this window open?
This window opens outwards, which is standard for South African timber windows. Inward opening is not supplied unless specifically requested and is extremely rare.
What finish is applied to this window?
The window is supplied unfinished. After installation, apply a quality exterior wood paint, stain, or sealer suitable for timber windows. Seal all surfaces — including the bottom rail and any end grain — to protect against moisture and extend the life of the window.
What size is this window?
The SD5229 measures 2820mm wide × 1490mm high × 90mm deep. This is a large-format window suited to wide openings such as living rooms, entertainment areas, or feature walls.

Lead time is 14–21 days from order confirmation. Nationwide delivery is available across South Africa.
