What Is a Skylight?
A skylight is more or less a window on your roof. It can offer great views and let ample amounts of light into a room.
- Skylights come in different styles, like fixed and vented
- They also come in a lot of custom shapes and sizes
- Some skylights can open to allow for air flow
What Is a Sun Tunnel?
A sun tunnel uses a reflective tube to bring light from the outside into small rooms, like:
- Hallways
- Closets
- Bathrooms
- Laundry rooms
This is more of a soft, diffused light. You don’t get a view of the sky, but you do get light in areas that might otherwise be dark.
Key Differences: Skylights vs. Sun Tunnels
Let’s break down the major differences between skylights and sun tunnels.
1. Installation
Skylights and sun tunnels differ greatly in complexity, timelines, and the disruptiveness of their installation.
Skylights:
- A major construction project
- If you don’t already have one, installation requires:
- Framing
- Drywall
- Paint
- Multiple trades involved
- More disruptive, longer installation timeline
Sun Tunnels:
- Much simpler installation
- Requires a small cut in the roof and ceiling
- Can often be installed in 90 minutes to 3 hours
- Less disruptive
2. Light Output
Skylights:
- Bring in lots of natural light
- Offer a view of the sky
- Better for large rooms
Sun Tunnels:
- Let in diffused light
- Perfect for small or dark areas
The larger the room, the more likely you’ll want a skylight as opposed to a sun tunnel.
3. Ventilation
Skylights:
- Some models can open to let in fresh air
Sun Tunnels:
- Sealed and fixed
- No ventilation
4. Aesthetic Impact
Skylights:
- Can be a showstopping architectural feature
Sun Tunnels:
- More subtle and functional
- Blend into the ceiling like a light fixture
5. Energy Efficiency
Skylights:
- Can cause heat gain or loss if not installed correctly
Sun Tunnels:
- Tend to be slightly more energy efficient
- Less temperature fluctuation
6. Cost
Skylights:
- Typically cost $2,100 to $5,800 for installation
- Price depends on type and accessories
Sun Tunnels:
- More budget-friendly
- Usually costs $650 to $2,200, including materials and labor
7. Maintenance & Durability
Skylights:
- Can develop leaks over time
- May need to be replaced or resealed
Sun Tunnels:
- Fewer parts
- Require very little maintenance
When Should You Choose a Skylight?
Go with a skylight if:
- You want bright natural light in large rooms
- You prefer ventilation options
- Your home has a strong design focus
When Is a Sun Tunnel The Right Choice?
Choose a sun tunnel if:
- You need light in hallways, closets, bathrooms, laundry rooms, or dark kitchens
- You’re on a budget
- You want a quick, non-invasive install
Can You Use Both?
Absolutely! Many homeowners use skylights for main living spaces and sun tunnels to brighten up smaller, darker areas. It’s a great way to get the best of both worlds.
