When converting an attic, the windows you choose do more than just add light. They shape the entire space—its comfort, function, energy performance, and feel. And while brands like Fakro and Velux dominate the market, choosing the right window type, quantity, and placement can have just as much impact as choosing the right brand.
In this guide, we break down Fakro vs Velux roof windows for attic conversions, and share the expert insights we’ve gained from thousands of installs across Australia.
️ Why Roof Windows Matter in Attic Conversions
Attics are often underlit, underused, and underventilated. Adding roof windows transforms them into bright, breathable, and liveable rooms. The right window setup can:
- Flood the space with natural light
- Improve airflow and reduce moisture buildup
- Boost thermal performance year-round
- Create headroom and openness—especially with centre-pivot and top-hung styles
- Increase property value and usability
At Roof Space Renovators, we’ve worked on thousands of attic conversions across Australia. We’ve seen firsthand how the right window brand, quantity, and placement can make or break a space.
Placement & Quantity: It’s Not Just the Brand That Matters
Even the best window won’t perform if it’s poorly placed or the room only gets half the light it needs. Smart attic conversions start with a strategy for window layout.
How Many Roof Windows Do You Need?
A general guideline is to aim for 10–20% of your attic floor area in window glazing. But quantity also affects functionality:
- One large window: Works for small or square-shaped rooms.
- Two or more windows: Distributes light better and enhances cross-ventilation.
Think beyond symmetry. Placement should serve how you use the room—whether it’s an office, a bedroom, or a multi-use zone.
Strategic Placement Makes All the Difference
- North-facing: Brighter, warmer light (great for living areas or offices).
- South-facing: Soft, consistent light (ideal for bedrooms).
- Opposite slopes: Create cross-breeze and light balance.
- Higher placement: Creates a lightwell effect in narrow or low-pitch attics.
We always tailor the configuration to your unique roof structure and lifestyle goals.
