What Type of Skylight Works Best in a Loft Conversion?
By Skylights.co.uk
Planning a loft conversion and wondering “What type of skylight should I install?” You’re not alone — it’s one of the most common questions we hear from homeowners creating a new bedroom, office, or chill-out space in the roof.
The right skylight makes a huge difference. It adds natural light, enhances the feeling of space, and helps regulate temperature and airflow — all while making your loft feel like a proper, livable room.
We recommend a simple formula: use a frameless fixed Skylight to bring in elegant daylight, and pair it with a Roto Roof Window for controllable ventilation. Here's why that combo works beautifully — and how to get it right.

💬 Real Questions People Ask About Loft Skylights
A mix of fixed and vented skylights works best. Frameless fixed skylights give you beautiful sky views and natural light, while a vented roof window helps with airflow and keeps the room comfortable.
Not always — but it’s a good idea to have at least one. For bedrooms or office spaces, we recommend combining a fixed skylight (like our Regal Glass model) with a Roto Roof Window that opens easily for ventilation.
Yes! Most loft conversions in the UK have pitched roofs, and both frameless skylights and roof windows can be installed directly into them — depending on angle and roof structure.
Not if you choose one with high-performance glazing. Our Regal Glass Skylights feature triple-glazed, low-E glass, which helps maintain the right temperature all year round.
Yes — especially Roto Roof Windows, which offer high insulation, built-in ventilation, and even emergency exit capability on some models.
🔍 Skylight Options for Loft Conversions (Compared)
| Skylight Type | Best For | Why It Works |
|---|---|---|
| Frameless Skylight | Daylight, views, clean design | Sleek, fixed, minimal, ultra-modern – perfect for bedrooms |
| Roto Roof Window (Vented) | Ventilation, moisture control | Opens manually or electrically, ideal for bathrooms & lofts |

| Flat Roof Rooflight (Pitched adaptors) | Horizontal surfaces | Works on dormers or flat rear extensions |
🧠 Why Frameless Fixed Skylights Are Perfect for Lofts
✔️ Edge-to-edge glass for panoramic sky views
✔️ Minimal frame means more light and a cleaner look
✔️ No moving parts = lower cost + zero maintenance
✔️ Triple glazing keeps your loft warm in winter and cool in summer
✔️ Flush fit with roofline enhances a modern interior
✔️ Perfect for bedrooms, home offices, and studios
💡 Design Tip: Use one large skylight above the main living area or bed, then add a Roto Roof Window on the opposite side to create airflow and cross-ventilation.
🛠️ Installation Tips for Loft Skylights
✅ Match your skylight to your roof pitch – Roto windows fit into pitched tiles; our Skylights require structural opening and upstand.
✅ Don’t forget blinds or solar shading – especially if your loft faces east or south.
✅ Use at least one vented skylight or roof window – it helps with condensation, especially in bedrooms or ensuites.
✅ Position carefully – centred skylights look clean, but offset ones often spread light more evenly.
✅ Always use a professional – particularly for flush or frameless skylight installations.
