In this article, we’ll clear that up. We’ll explain what each term typically refers to, where they overlap, and how to know which product is right for your project.
The Short Answer
The terms window shroud, sun hood, and window hood all refer to external aluminium structures fixed around or above a window opening. They shade glass, provide weather protection, add architectural definition, and in many cases help meet passive solar design requirements for BASIX compliance.
The difference comes down to coverage. How many sides of the window does the product wrap around? That’s the key question.
What Is a Sun Hood?
A sun hood is typically a single projection element. It sits above the window and extends outward from the facade, shielding the glass from direct overhead sun.
Think of it like a visor for your window. It’s straightforward, effective, and well suited to situations where the primary goal is solar control on a south or north-facing elevation.
Sun hoods are often used on residential projects where a clean, minimal profile is preferred, and where budget or design intent doesn’t call for a full framed surround.
What Is a Window Hood?
Window hood is a broader term that’s used interchangeably with sun hood in many contexts. It refers to a hood-style projection above the window, and at Alumac we use this term across our range of top-projection products.
You’ll see window hoods specified on residential and commercial projects across NSW and Australia where the aim is to combine sun mitigation with a refined architectural finish. Our window hoods are manufactured in Sydney from high-grade aluminium, CNC laser cut and professionally powder coated.
The terms sun hood and window hood, for most practical purposes, refer to the same product.
What Is a Window Shroud?
A window shroud goes further. Where a sun hood or window hood projects from the top only, a window shroud typically wraps around multiple sides of the window opening, usually the top and two sides, and in some configurations all four sides.
This creates a stronger architectural frame around the window. The effect is more pronounced, the shadow detail more defined, and the visual impact on the facade more deliberate.
Window shrouds are a popular choice for architects and designers working on premium residential, multi-residential and commercial projects where the window is meant to read as a feature, not just a functional opening.
They also offer more comprehensive sun mitigation on elevations where a top-projection alone isn’t sufficient, and they can contribute to passive solar and BASIX requirements on eligible projects.
When Does the Distinction Matter?
For most projects, the terminology matters less than the specification. What you actually need to nail down is:
- Coverage. Do you need a top projection only, or a full surround? This depends on the elevation, orientation and design intent.
- Profile depth. A deeper projection shades more glass. The right depth depends on latitude, orientation and the amount of solar control required.
- Facade integration. Is the product sitting proud of brickwork, over cladding or on a rendered surface? This affects fixing method and visual detail.
- Aesthetic intent. Are you going for a slim blade-like profile or a bolder architectural statement? The right product range is determined by the look you’re after.
At Alumac, our range includes products that function as both sun hoods and window shrouds depending on how they’re configured. Our Modline, Trendline, Trendline Plus+ and Centurion systems can all be adapted to top-projection or multi-sided configurations to suit the project.
A Quick Reference
| Term | Coverage | Common Use |
|---|---|---|
| Sun Hood | Top projection only | Solar & weather control, residential and commercial |
| Window Hood | Top projection only | Same as sun hood, terms used interchangeably |
| Window Shroud | Top and 2-4 sides (multi-face) | Architectural framing, premium facades |
So What Should You Specify?
If your project needs a clean, cost-effective shading solution, a sun hood or window hood will do the job well.
If you want the window to read as a considered architectural element, a window shroud, with its additional side coverage, delivers a stronger result.
And if you’re not sure which is right? That’s what we’re here for. Alumac works with architects, builders and developers across NSW and Australia to determine the right product, configuration and profile for each project. We manufacture everything in our Sydney factory, so we can work to custom dimensions and discuss your design intent before anything goes into production.
