What’s the Difference Between a Fixed and Vented Skylight?
By Skylights.co.uk
If you’re planning to add a skylight to your home, you might be asking:
“Do I need one that opens, or will a fixed skylight do the job?”
It’s a common question — and the answer depends on what you want from your space.
Both fixed and vented skylights have their benefits. But if you're after clean design, loads of daylight, and zero hassle, a frameless fixed skylight — might be all you need.
In this guide, we’ll explain the real difference between fixed and vented skylights, where each one works best, and how to choose the right option for your home or extension.

💬 Questions About Fixed vs Vented Skylights
It’s simple — fixed skylights don’t open, and vented skylights do (either manually or electrically). Vented models are great for airflow, while fixed ones focus purely on light and aesthetics.
Many homeowners choose frameless fixed skylights for their sleek look, maximum light, and zero maintenance. They’re ideal for spaces that don’t need extra ventilation.
In moisture-prone rooms like bathrooms or kitchens — yes. But in most living spaces or bedrooms, a fixed skylight (like our Regal Glass range) offers all the light you need at a lower cost.
Modern vented skylights are very reliable. Still, fewer moving parts = fewer things to maintain, which is one reason fixed skylights are popular in low-maintenance homes.
Absolutely. Many people pair fixed rooflights with nearby windows or Roto Roof Windows for airflow. It’s a stylish, cost-effective combo.

🧠 When to Choose a Fixed Skylight
Fixed skylights — especially frameless models — are a go-to choice for:
✔️ Living rooms — Clean, open light with no need for airflow
✔️ Kitchens with extractors — Already have ventilation? Then enjoy the daylight
✔️ Bedrooms — Use blackout blinds or pair with openable windows nearby
✔️ Hallways & corridors — No vents needed, just pure daylight
✔️ Modern extensions — Frameless skylights disappear into the roof, creating that wow-factor look
💡 Tip: If you’re building a flat roof extension and want it to feel bigger, install a large fixed Rooflight (e.g., 1200 x 2500mm) for seamless, uninterrupted light.
🌬 When to Choose a Vented Skylight
Vented skylights (manual, electric, or solar) are ideal for:
✔️ Bathrooms & ensuite lofts — Removes steam and moisture
✔️ Small kitchens — Helps eliminate cooking odours without turning on the fan
✔️ Utility rooms — Extra airflow while maintaining privacy
✔️ Loft conversions — Add one Roto Roof Window alongside a fixed unit for airflow + light
💡 Roto Roof Windows are a great choice for vented skylights — they’re high-quality, built for pitched roofs, and open manually or via motorised control, depending on your needs.
🛠 Installation + Design Tips
✅ Combine fixed and vented skylights for the best of both worlds
✅ Use a vented Roto window where you need airflow, and fixed Rooflights for open-plan brightness
✅ Install fixed skylights in areas where you want zero fuss — no motors, no blinds, just beautiful light
✅ Don’t forget blinds — optional with both types if you need privacy or solar control
🏡 Common Room Setups (Fixed vs Vented Skylight Pairings)
| Room Type | Recommended Setup | Why It Works |
|---|---|---|
| Open-plan Kitchen | 2 Fixed Rooflights + 1 side window | Clean look, light from above, airflow from side |
| Loft Bedroom | 1 Fixed + 1 Roto Roof Window | Daylight + ventilation + easy operation |
| Ensuite Bathroom | 1 Roto Roof Window (vented) | Handles moisture, doesn’t need extra light |
| Living Room | 1–2 Frameless Fixed Skylights | Big views, beautiful light, no need for vents |
| Hallway / Landing | 1 Fixed Rooflight (compact size) | Brightens narrow space with minimal effort |
✅ Final Thoughts: So, Which One’s Right for You?
If you want the cleanest look, zero maintenance, and maximum natural light, we recommend going with a frameless fixed skylight — especially our skylight range. It’s the ideal fit for modern homes, extensions, and bright, beautiful spaces.
But if ventilation is a must — like in a bathroom or snug loft space — a Roto Roof Window gives you airflow without compromising on design or quality.
The truth? Many homeowners choose both. One fixed, one vented — smart, stylish, and efficient.
