If you've just had new aluminium windows installed, you might be surprised to find a visible gap between the window frame and the internal wall.
Many homeowners assume that once windows are installed, everything is “done” — but that’s rarely the case.
In fact, most window suppliers don’t include internal finishing around the window in their service scope. This final part, known as the window reveal finish, is often left to be completed by your plasterer or carpenter.
So what exactly is a window reveal finish, and what are your options?

- What Is a Window Reveal Finish?
The window reveal finish refers to how the internal wall — usually plasterboard — finishes against the window frame. It's what makes the transition from wall to window look clean, complete, and intentional.
This seemingly small detail plays a big role in defining the interior style of a room. Some finishes are classic and decorative; others are sleek and minimal. Picking the right one depends on your home’s aesthetic, your budget, and the skill of your tradespeople.
- The Three Main Internal Reveal Styles in Australia
1）Architraves – The Traditional Trim
Architraves are timber mouldings that frame the window opening, adding a defined border between wall and frame. They're common in traditional Australian homes and renovations.

- Pros: Easy to install, hides wall imperfections, timeless aesthetic
- Best for: Heritage homes, renovations, classic interiors

2）Square-Set / Plaster Finish / Ezy Reveal – The Modern Minimalist

Also referred to as Ezy Reveal or Plaster Reveal, this style eliminates trims completely. The plasterboard runs flush to the window frame, and a reveal bead (like EzyBead or angle bead) is installed at the corner to create a crisp edge.
At RS Doors & Windows, we allow a 2mm gap between the aluminium frame and timber subframe specifically for this purpose — making it easier for your plasterer to slide in the bead and finish cleanly.
- Pros: Seamless, minimal, architectural look
- Best for: New builds, modern duplexes, design-driven homes

3）Shadowline – The Designer Hybrid

Shadowline reveals are a contemporary twist — a slim recessed groove is created between wall and frame, offering a modern yet softly defined finish.
They require very precise framing and plastering, but deliver a premium architectural effect that’s popular in custom homes.
- Pros: Subtle depth, clean visual line, stylish modernity
- Best for: Architect-designed homes, high-end builds

If you're unsure, it's always a good idea to speak to your builder.
- How Does RS Help Prepare for These Finishes?
Proper reveal finishing starts with proper window installation. When we install aluminium windows into timber subframes, we leave a consistent 2mm clearance at the interface. This ensures that plasterers can insert their chosen reveal bead (angle bead or shadowline bead) smoothly, without damaging the frame.
Important note: Reveal beads, angle trims and plaster finishing are not included in standard window installation. They're typically handled by your builder, plasterer, or carpenter.
