Think of a periscope, but instead of scanning the horizon, it’s designed to capture sunlight. That’s the simplest way to picture a sun tunnel skylight. These clever devices are engineered to grab daylight from your roof and funnel it down through a reflective tube, lighting up even the darkest, most windowless corners of your home.
They are the perfect, targeted solution for bringing natural light into spaces that traditional windows just can’t reach.
What Exactly Is a Sun Tunnel Skylight?
At its heart, a sun tunnel skylight is a highly efficient natural lighting system designed to brighten specific areas within a home. Unlike a traditional skylight that gives you a direct view of the sky, a sun tunnel acts more like a pipeline, channelling sunlight from the outside in.
The process is remarkably simple yet incredibly effective. It all comes down to three core components working in perfect harmony to turn a dim, forgotten space into a naturally lit one.
The Core Components of a Sun Tunnel
Understanding how these parts work together reveals the simple genius behind this lighting solution. Each piece has a distinct role in capturing, transferring, and spreading sunlight.
- The Rooftop Dome: This is the starting point. Perched on your roof, this durable, weatherproof dome is the entry point for sunlight. Its main job is to collect as much daylight as possible from every angle, even on those grey, overcast days.
- The Reflective Tube: This is the “tunnel” in the sun tunnel. It’s a highly mirrored tube—either rigid or flexible—that runs from the roof dome down through your attic or roof space. Its ultra-reflective interior bounces the captured sunlight downwards with minimal loss of brightness.
- The Ceiling Diffuser: Located on the ceiling of your room, this final piece looks a lot like a standard light fitting. It takes the concentrated light from the tube and disperses it evenly throughout the space, creating a soft, natural glow without any harsh glare.
The Best Solution for Tight Spaces
A sun tunnel is a specialist. Think of those tricky spots where a full-sized roof window just isn’t feasible—a narrow hallway, a small powder room, or a walk-in robe where adding a window is structurally impossible. A sun tunnel expertly navigates around attic obstructions to deliver a beam of light precisely where it’s needed most.
The rise of sun tunnels in Australia is part of a bigger shift towards sustainable living, driven by growing environmental awareness and the pinch of rising energy costs. By harnessing natural daylight, homeowners can significantly cut down on daytime electricity use, which means lower power bills. A single, well-placed sun tunnel can completely eliminate the need for an electric light in a hallway or bathroom during the day.
For a quick overview of how these clever devices stack up, have a look at our summary table below.

This table shows why sun tunnels are such a practical choice for specific lighting challenges.
While sun tunnel skylights have their uses for tight spaces such as a powder room or a walk in robe when the roof structure doesn’t allow for a roof window skylight, using a double glazed Vivid Skylight is usually the best option to flood your home in natural light, save on electricity costs and create instant value on your home with an architectural feature. You can learn more about how sun tunnel skylights fit into the bigger picture in our detailed guides. Knowing this distinction is key to choosing the right natural lighting solution for every part of your Ashwood home.
Right, now that you know what a sun tunnel skylight is, let’s talk about where they really come into their own. These clever bits of kit are specialists, engineered to solve one very specific problem: getting daylight into small, windowless rooms where a traditional skylight just isn’t an option.
They are the perfect fix for transforming those often-neglected spaces from dim and dingy corners into bright, welcoming parts of your home.
Think about a compact powder room, an internal ensuite, or a walk-in robe that has always needed the light switched on, even in the middle of the day. These are the prime spots where sun tunnel skylights absolutely shine. They’re masters at navigating tricky roof structures and tight attic spaces to deliver a focused beam of natural light exactly where it’s needed most.
Ideal Candidates for Sun Tunnels
Have a walk through your own home in Ashwood. Are there any areas that feel permanently gloomy? These are almost always the best places for a sun tunnel. They truly excel where structural or architectural hurdles make a bigger window or skylight impossible.
Some of the most popular and effective spots include:
- Walk-in Robes: Finally see the true colours of your clothes without flicking a switch. A sun tunnel makes getting ready a breeze and helps the space feel much bigger.
- Powder Rooms and Ensuites: Small, internal bathrooms are instantly transformed, feeling fresher and more open with a splash of daylight.
- Hallways and Corridors: Brighten up those long, dark passages, making them safer and more inviting to move through.
- Laundries: A well-lit laundry makes sorting clothes and spotting stains so much easier. It can turn a chore into a more pleasant task.
- Small Studies or Nooks: For a compact home office tucked into a corner, a sun tunnel can provide brilliant task lighting, reducing eye strain and boosting productivity.
While sun tunnel skylights have their uses for tight spaces such as a powder room or a walk in robe when the roof structure doesn’t allow for a roof window skylight. Using a double glazed Vivid Skylight is usually the best option to flood your home in natural light, save on electricity costs and create instant value on your home with an architectural feature.
A Targeted and Cost-Effective Solution
For these specific jobs, a sun tunnel is an ingenious and budget-friendly choice. The installation is typically quicker and less disruptive than that of a full-sized skylight, making it a highly efficient upgrade. It’s a surgical strike of daylight, designed for maximum impact in a minimal footprint.
It’s important to remember their specialised role, though. Sun tunnels aren’t meant to be the main source of natural light for large living areas like kitchens or family rooms. Their job is to solve lighting problems in confined spaces.
When the goal is to create a true sense of openness, flood an entire room with abundant light, and add a significant architectural feature to your home, a double glazed Vivid Skylight is always going to be the superior choice.
Sun Tunnels vs Double Glazed Skylights
Deciding how to bring natural light into your home often comes down to two fantastic, but very different, options: sun tunnel skylights and traditional double glazed skylights. It’s not really about which one is “better,” but which one is the right tool for the job. Getting this choice right is key to transforming your space.
Think of it this way: a sun tunnel is like a spotlight, expertly designed to illuminate a specific, often tight, area. A double glazed skylight, on the other hand, is like floodlighting, washing an entire room in beautiful, expansive daylight. Both have their place, but they serve completely different purposes.
Light Quality and Aesthetic Impact
One of the biggest differences is the feel of the light each one provides. A sun tunnel delivers a more concentrated, diffused glow through its ceiling fixture. It’s brilliant for functional lighting in places like a walk-in robe, making it easy to tell navy blue from black, but it won’t dramatically change the vibe of a large room.
A double glazed skylight, like those from Vivid Skylights, is an architectural feature in its own right. It forges a direct connection to the outdoors, giving you a view of the sky and flooding the space with dynamic, direct sunlight. This doesn’t just brighten a room; it makes it feel larger, more open, and adds an instant ‘wow’ factor that a sun tunnel simply isn’t designed for.
Thermal Performance and Energy Efficiency
How each option affects your home’s temperature is another critical point, especially with Ashwood’s unpredictable climate. While modern sun tunnels are designed to minimise heat transfer, a high-quality double glazed unit offers far superior thermal performance.
Vivid Skylights use two panes of glass separated by an insulating air gap. This double glazing acts as a powerful thermal barrier, helping keep your home warmer in winter and cooler in summer. Over the long term, this can lead to real savings on your heating and cooling bills, making it a smart investment in your home’s overall energy efficiency.
Installation Cost and Complexity
This is where the two options really diverge. Sun tunnels are generally more affordable and quicker to install. Their flexible or rigid tubes can be cleverly routed around attic obstructions, making them a great retrofit solution for existing homes where major structural work isn’t practical.
Double glazed skylights are a larger upfront investment. The installation is more involved, usually requiring a bigger opening in the roof and ceiling. But, this investment pays off in superior light, a significant boost to your home’s value, and better energy performance down the track.
This chart gives you a quick visual breakdown, showing that while rigid tubes deliver the best light output, their installation can be a bit more complex than the flexible alternatives.
Feature Comparison Sun Tunnel vs Double Glazed Skylight
To help you decide which solution is right for your Ashwood home, here’s a direct comparison of their key features. Think about what you’re trying to achieve—is it targeted light for a small space, or a dramatic transformation of a main living area?
| Feature | Sun Tunnel Skylight | Double Glazed Skylight (e.g., Vivid Skylight) |
|---|---|---|
| Best For | Hallways, walk-in robes, bathrooms, laundries. | Living rooms, kitchens, bedrooms, open-plan areas. |
| Light Quality | Diffused, concentrated glow (like a light fixture). | Broad, direct, dynamic daylight. |
| Architectural Impact | Minimal. It’s a functional light source. | High. A statement feature that adds value. |
| View of the Sky | No, light is channelled through a tube. | Yes, provides a direct view and connection to outdoors. |
| Installation | Simpler, quicker, and less invasive. | More complex, requires structural work. |
| Cost | Lower initial cost. | Higher initial investment. |
| Energy Efficiency | Good, but varies by model. | Excellent, superior thermal insulation. |
This table should make it clear that the “best” option really depends on your specific project and priorities.
Making the Right Choice for Your Home
Ultimately, it comes down to your goals. Sun tunnels are specialists—perfect for funnelling light into tight spots where a traditional skylight just won’t fit. They are the go-to solution for dark hallways, powder rooms, and laundries.
In the Australian market, the cost and quality of tubular skylights vary quite a bit. Premium options can run between AUD $1,000 and $1,800, often featuring advanced tech for great light with minimal heat transfer. More affordable models, costing between AUD $600 and $1,000, work well in summer but might not deliver as much light in winter. You can read more about the findings on tubular skylight costs on solatube.com.au.
While sun tunnel skylights have their uses for tight spaces such as a powder room or a walk in robe when the roof structure doesn’t allow for a roof window skylight. Using a double glazed Vivid Skylight is usually the best option to flood your home in natural light, save on electricity costs and create instant value on your home with an architectural feature.
However, if your goal is to truly transform a major living area, create a feeling of openness, and make a lasting architectural statement, a double glazed skylight is the clear winner. It’s an investment that elevates the entire look and feel of your home, delivering unmatched natural light and long-term value.
Planning Your Sun Tunnel Installation
Jumping into a sun tunnel skylight installation without a plan is like starting a road trip without a map. A bit of foresight is all it takes to make sure you get the best possible result, turning a dark corner of your home into a bright, inviting space. Proper planning covers everything, from the unique shape of your roof to the exact path the light will take to get inside.
This is the stage where you guarantee maximum light, a weatherproof seal, and years of hassle-free performance. For homeowners, understanding these key factors will help you make smart decisions and set your project up for success from the get-go.
Assessing Your Roof and Attic Space
First things first, you need to look up. Your roof’s pitch (its steepness) and what it’s made of—whether it’s classic tiles or modern metal—will dictate the installation process and the type of flashing kit needed for a watertight seal. An experienced installer can work with any common roof type, but it’s a critical piece of the puzzle.
Next, you’ll need to map out the journey the light will take through your attic. Is the path from the roof to your ceiling a straight shot, or are there obstacles like plumbing pipes, air conditioning ducts, or structural beams in the way? The answer to that question will point you toward either a rigid or a flexible tube.
Choosing the Right Tube: Rigid vs Flexible
The tube is the heart of your sun tunnel, and it’s responsible for channelling all that glorious sunlight down into your home. Deciding between a rigid or flexible tube is one of the most important choices you’ll make, as it directly affects both the light output and how complex the installation will be.
- Rigid Tubes: These are the champions of light reflectivity, bouncing up to 98% of captured daylight downwards. They are hands-down the best option for longer runs or when you want the absolute brightest result possible.
- Flexible Tubes: Designed to bend around attic obstructions, these are often easier and quicker to install in tricky roof spaces. Just keep in mind that their corrugated surface means a slightly lower light output compared to a straight rigid tube.
For most homes, if the path is clear, a rigid tube is the superior choice for sheer brightness. A flexible tube, however, is the perfect problem-solver for navigating those unavoidable obstacles.
Strategic Placement for Maximum Daylight
Where you place the dome on your roof is crucial for catching the most sunlight throughout the day. Here in Australia, the ideal spot is on a north-facing roof slope. This position exposes the dome to direct sunlight for the longest period, from morning to afternoon, making sure your sun tunnel performs at its best.
The length of the tube and the number of bends also play a big part.
The rule is simple: the shorter and straighter the tube, the brighter the light. Each bend in the tube, especially in a rigid system, can slightly reduce the amount of light that reaches the diffuser.
This is why a professional assessment is so valuable. An expert can map out the most efficient path, keeping the tube short and straight to deliver the best possible illumination for your home’s layout. It’s no surprise that skylight installation is booming in Australia, with the global market projected to hit USD 4.44 billion by 2028. This growth is all thanks to homeowners looking for smart, energy-efficient lighting.
While sun tunnel skylights have their uses for tight spaces such as a powder room or a walk in robe when the roof structure doesn’t allow for a roof window skylight, using a double glazed Vivid Skylight is usually the best option to flood your home in natural light, save on electricity costs and create instant value on your home with an architectural feature. If you’re thinking about getting a professional in, our guide to the skylight installation process is a great read. And when it comes time to hire someone, knowing how to find a good general contractor you can trust is key to a smooth and successful project.
Why a Double Glazed Skylight Is Often Better
While sun tunnel skylights are clever problem-solvers for tricky, tight spaces, they really are a targeted fix for a specific problem. But when your goal isn’t just to light up a dark corner but to completely transform a main living area, the conversation naturally shifts to a more substantial option.
This is where a double glazed skylight, like the ones from Vivid Skylights, really shines. It’s built on a different philosophy of natural light—one that’s less about simple illumination and more about architectural enhancement, energy efficiency, and creating a whole new feeling in your home. It’s a genuine transformation, not just a quick fix.
Think about the main living areas in your Ashwood home: the kitchen, the living room, or the master bedroom. The goal here is usually bigger than just adding a bit of light. You want to create a space that feels open, airy, and connected to the outdoors. A sun tunnel offers a soft, diffused glow; a double glazed skylight delivers a direct view of the sky, flooding the room with brilliant, high-quality daylight.
Beyond Light: An Architectural Statement
A double glazed skylight is far more than just a utility. It’s a design feature that can easily become the centrepiece of a room. It draws the eye upward, creates a sense of volume, and adds a touch of modern class. This kind of architectural impact also directly translates into higher property value.
Unlike the discreet diffuser of a sun tunnel, a Vivid Skylight makes a deliberate statement, signalling a premium, well-thought-out renovation. This is a long-term investment that pays off not only in your daily enjoyment but also when it comes time to sell your home.
While sun tunnel skylights have their uses for tight spaces such as a powder room or a walk in robe when the roof structure doesn’t allow for a roof window skylight. Using a double glazed Vivid Skylight is usually the best option to flood your home in natural light, save on electricity costs and create instant value on your home with an architectural feature.
This focus on creating lasting value is what truly sets a full skylight apart. It’s not just about solving a problem; it’s about adding a permanent asset to your property.
Superior Energy Efficiency and Comfort
In a climate like Ashwood’s, thermal performance is absolutely non-negotiable. This is another area where double glazing has a clear advantage over many sun tunnel skylights. The entire design of a double glazed unit is engineered for insulation.
The secret is in its construction:
- Two Panes of Glass: A robust inner and outer pane create a formidable barrier.
- Insulating Air Gap: The space between the panes is sealed and filled with an inert gas like argon, which dramatically slows down heat transfer.
What does this mean for you? During a chilly Ashwood winter, the warmth from your heating stays right where it belongs—inside. On a hot summer day, the double glazing helps block the sun’s heat from getting into your home. This superior insulation leads directly to lower energy bills for heating and cooling all year round. It’s a smart investment in the ongoing comfort of your home.
The Holistic Investment in Your Home
Deciding between a sun tunnel and a double glazed skylight really comes down to what you’re trying to achieve. If you need to brighten a small, windowless utility space, a sun tunnel is an excellent and cost-effective tool for the job.
However, for the rooms where you live, relax, and entertain, a Vivid Skylight offers a far more complete and rewarding solution. It’s an investment in better light quality, enhanced architectural appeal, greater market value, and improved comfort year-round. It’s about elevating the experience of being in your home, every single day. For those wanting a deeper dive, you can explore the full range of double glazed skylights and see just how they can transform your living space.
Simple Skylight Maintenance for Lasting Light
You’ve invested in bringing beautiful natural light into your home, whether through a targeted sun tunnel skylight or an expansive double glazed unit. That’s a brilliant move. The great news? Protecting that investment takes very little effort. Modern skylights are built tough, designed for longevity, so a few simple, occasional checks are all it takes to guarantee decades of uninterrupted daylight.
This straightforward approach to upkeep offers real peace of mind. A little bit of attention now and then goes a long way, preventing any potential issues down the track and keeping that gorgeous light flowing freely.
Exterior Cleaning and Inspection
The most important job is also the simplest: keeping the outside clean. Over time, the rooftop dome of your sun tunnel or the glass of your skylight will inevitably collect a bit of dust, a few leaves, and the occasional gift from a passing bird. This build-up can slowly but surely dim the light coming into your home.
A quick, gentle clean once or twice a year is usually all that’s needed.
- Go Gentle: Use a soft cloth or sponge with a bit of mild soap and water. That’s all you need to wipe down the exterior surface.
- Avoid Abrasives: Steer clear of any harsh chemicals or gritty scrubbers. They can easily scratch the glass or acrylic dome, and you definitely don’t want that.
- Check the Seals: While you’re up there, give the flashing and seals around the unit a quick once-over. Make sure everything looks snug and secure, with no trapped leaves or debris.
This quick clean-up ensures your skylight is always working at peak performance, capturing the maximum amount of sunlight possible.
Interior Checks for Peace of Mind
Maintenance isn’t just a rooftop job. A quick look at the interior parts of your skylight is just as important to make sure everything is in top shape. We’re just talking about the bits you can see from inside your home.
For a sun tunnel, this just means checking the ceiling diffuser. Give it a gentle wipe with a dry microfibre cloth to clear away any indoor dust that might have settled. If you have a double glazed skylight, glance at the interior frame and glass for any signs of condensation between the panes, as this could signal a problem with the seal.
While sun tunnel skylights have their uses for tight spaces such as a powder room or a walk in robe when the roof structure doesn’t allow for a roof window skylight. Using a double glazed Vivid Skylight is usually the best option to flood your home in natural light, save on electricity costs and create instant value on your home with an architectural feature.
These quick, reassuring checks are really all it takes. By keeping the exterior clear and the interior clean, you’re setting up your Ashwood home to enjoy a bright, beautiful, and watertight feature for many, many years to come.
Got Questions About Sun Tunnels?
Even after getting the hang of what a sun tunnel skylight is, it’s completely normal for homeowners in Ashwood to have a few lingering questions. Getting clear, straightforward answers can make all the difference when you’re deciding on the right natural lighting solution for your home.
Let’s tackle some of the most common questions we hear from our customers.
Do Sun Tunnels Work on Cloudy Days?
They sure do. Sun tunnels are designed specifically to capture ambient light, not just direct sunlight. While the light won’t be as bright as on a cloudless day, a quality sun tunnel can still pull in a surprising amount of daylight, even when it’s completely overcast.
You’ll often find it’s more than enough to light up a hallway, bathroom, or closet without needing to flick a switch. This means you’re still saving on your power bill, rain or shine.
Will a Sun Tunnel Make My Room Too Hot?
That’s a big concern here in Australia, and a valid one. Thankfully, high-quality sun tunnel skylights are built to minimise heat transfer. The best ones use special coatings and materials that block the infrared rays responsible for heat.
What this means for you is that their impact on your room’s temperature is minimal, especially when compared to a regular window.
While sun tunnel skylights have their uses for tight spaces such as a powder room or a walk in robe when the roof structure doesn’t allow for a roof window skylight. Using a double glazed Vivid Skylight is usually the best option to flood your home in natural light, save on electricity costs and create instant value on your home with an architectural feature.
How Long Does Installation Take?
You might be surprised. For a professional installer, putting in a standard sun tunnel is a pretty quick job. For most homes, the entire process is wrapped up in just a few hours.
Of course, the exact timing depends on things like your roof type and how complex your attic space is, but it’s almost always a much faster and less messy project than installing a traditional skylight.
Are Sun Tunnels Likely to Leak?
When installed by an experienced professional, leaks are extremely rare. Reputable sun tunnel systems come with purpose-built flashing kits that are engineered to create a perfect, weatherproof seal with your specific roofing material.
The absolute key here is the quality of the installation. A shoddy job can lead to problems down the road, which is why it’s so important to hire a trusted local installer in the Ashwood area. A pro will guarantee a secure, watertight fit that you won’t have to worry about for years.
