What Is an Awning Window?
An awning window is hinged at the top and opens outward from the bottom, creating a natural awning effect that allows ventilation even during light rain. This makes awning windows a popular choice in South African homes for kitchens, bathrooms, and living areas where airflow is needed without compromising weather protection.
What Is a Sublight?
A sublight is a fixed, non-opening glazed panel positioned below the opening casements in a window unit. It allows additional natural light to enter the room without adding further operable sashes, keeping the window profile clean and the mechanism simple. Sublights are commonly used in South African timber window designs to maximise light in taller wall openings.
About Meranti Timber
Meranti is a dense, durable tropical hardwood widely used in South African window and door joinery. Kiln-dried Meranti offers excellent dimensional stability, good resistance to moisture when correctly sealed, and a fine, consistent grain that accepts paint and stain finishes well. It is a long-established standard in quality South African residential construction.
Hardware Details
This window is fitted with solid brass handles for a premium, corrosion-resistant finish, and easy-clean yellow passivated mild steel hinges for smooth, durable operation. Yellow passivation is a chromate conversion coating applied to mild steel to improve corrosion resistance, making it suitable for interior and sheltered exterior window applications.
Frequently Asked Questions
Is glass included?
No. Timber windows are supplied as frames only, without glass. Glazing must be sourced separately from a local glazier. The frames are rebated and ready to accept standard glass thicknesses.
Can this window be painted?
Yes. Meranti timber takes paint and stain finishes well. Apply a quality wood primer before painting, and use an exterior-grade finish for any windows exposed to weather. Re-coat every 2–3 years depending on exposure.
Is this window suitable for exterior use?
Yes, with correct finishing and maintenance. Meranti timber windows are suitable for exterior applications when properly primed, painted or stained, and maintained. Ensure the cill is correctly weatherproofed and that appropriate flashing is installed.

This window is made to order and typically ships within 12–14 business days.
