Are Skylights Better Than Traditional Windows for Light?

By Regal Glass Group
Ever walked into a room and thought, “Why does this feel so dark even with windows?”
If so, you’re not alone — and the answer might just be overhead. Skylights are becoming a go-to solution for UK homeowners who want more natural light without knocking down walls or adding more vertical glazing.
So, what’s better for lighting up your space — a skylight or a traditional window?
At Regal Glass Group, we’ve helped thousands of people transform their homes with frameless fixed rooflights and custom skylight layouts, and the results are clear: skylights bring in more light, more evenly, and more beautifully. Let’s explore why.

💬 Questions About Skylights vs Windows
Yes — skylights let in up to 3 times more natural light than vertical windows of the same size. Because they face the sky directly, they capture light from above all day long.
You don’t need to choose one or the other. Skylights work best with windows — especially in darker rooms where side light just isn’t enough.
Skylight light is softer, more even, and spreads deeper into the room — reducing shadows and eliminating that gloomy "corner" effect you get with wall windows.
Absolutely. Even if your side windows get minimal sun, a skylight on top will bring in consistent daylight from above, all year round.
Not at all — especially frameless fixed rooflights. They have no moving parts, and self-cleaning glass options make them almost maintenance-free.

🧠 Why Skylights Bring in More (and Better) Light
☀️ 1. Direct Daylight Access
Skylights are installed in the roof, which means they’re exposed to 100% of the sky — not blocked by fences, neighbours, or walls like vertical windows.
☀️ 2. Light Travels Deeper Into the Room
Because the angle of light is vertical, it penetrates further across your floor plan — which means fewer dark spots and more even lighting across the day.
🔒 3. Privacy Without Compromise
You don’t need blinds or frosted glass to feel comfortable. Even in a bathroom, a fixed skylight provides daylight and privacy — all at once.
🎨 4. They Look Stunning
Minimalist, frameless rooflights sit flush to your ceiling and roof — adding light without breaking your clean lines or architectural style.

🏡 When Traditional Windows Still Shine
While skylights are amazing for bringing light in from above, traditional vertical windows still play a vital role:
✔️ Let you see views outside
✔️ Allow natural airflow when open
✔️ Perfect for heritage-style homes
✔️ Great paired with skylights for full coverage
The sweet spot? Use windows for ventilation and outlook, and skylights to flood your space with light from above.
🛠 Installation Tips
✅ Combine both when possible – Especially in kitchen/diner extensions
✅ Use larger fixed skylights in darker rooms – Let the light do the heavy lifting
✅ Install skylights in the middle of the room – For even light distribution
✅ Add blinds only if needed – Most skylights don’t need them for privacy
✅ Final Thoughts: Skylight or Window? Why Not Both?
When it comes to pure light quality and depth, skylights win hands down. They bring in more daylight, with fewer shadows, and make any room feel bigger, brighter, and more modern.
That said, you don’t have to choose — pairing skylights with your existing windows gives you the best of both worlds.
And if you’re aiming for clean lines and minimal design, frameless fixed skylights from Regal Glass are your best bet — especially when combined using our Modular Skylight Calculator for a completely custom layout.
