Stratco Sunroof vs Cooldek: Which Is Right for Your Home?
If you're planning a new patio, choosing between a Stratco Sunroof and Cooldek can be one of the biggest design decisions.
Both are premium Stratco products, but they solve different problems.
Cooldek gives you a permanent insulated roof with a clean ceiling-like finish.
Sunroof gives you the ability to control sunlight and airflow by opening or closing the louvre blades.
The right choice depends on your home, orientation, available space, budget and how you want to use the outdoor area.
If you're still exploring the broader range, you can also view our Stratco patios in Melbourne.
What Is a Stratco Sunroof?
A Stratco Sunroof is a motorised opening-roof system using adjustable louvre blades.
The blades can be opened to let in more sunlight and airflow, partially opened to help control ventilation, or closed when you want shade and weather protection.
One of the biggest advantages is natural light.
The louvres can open to around 90 degrees or more, which can allow significantly more light through compared with a permanent solid roof.
This can be especially useful where the patio sits outside:
a living room
kitchen
dining room
sliding doors
stacker doors
large windows.
If you want a deeper explanation of the system itself, our Stratco Sunroof Melbourne guide covers how it works and where it can make sense.
What Is Stratco Cooldek?
Cooldek is an insulated patio roofing system designed to provide permanent weather protection with a clean finished underside.
The underside has a ceiling-like appearance, which gives the outdoor area a polished, integrated look.
It is also very practical for mounting electrical components such as:
lights
ceiling fans
heatstrips.
For homeowners who want a larger permanently covered entertaining area, Cooldek can be a very practical solution.
If you're also comparing Cooldek with a standard fixed-roof patio, our Stratco Cooldek vs Outback Flat Patio guide explains that comparison in more detail.
Sunroof vs Cooldek: The Main Difference
The simplest way to think about the two systems is:
Cooldek gives you permanent insulated cover.
Sunroof gives you control over light and airflow.
With Cooldek, the roof remains closed all year. With Sunroof, you can decide how much sunlight and ventilation you want underneath the patio.
That difference can completely change which system suits a particular property.
Which Is Better for Heat and Comfort?
Cooldek has a natural advantage here because it is an insulated roofing system.
If the patio receives strong summer sun, the insulation helps reduce heat transfer through the roof and creates consistent shade underneath.
Sunroof approaches comfort differently.
Because the louvres can be partially opened, you can allow more airflow through the structure while still controlling the amount of direct sunlight entering the space.
So in practical terms, comfort can be good under both systems, but they achieve it differently.
Choose Cooldek if your priority is permanent insulated shade.
Consider Sunroof if you value the ability to adjust airflow and sunlight depending on the weather.
Which Is Better for Natural Light?
Sunroof has a clear advantage when natural light is a major priority.
The louvres can open widely, allowing much more daylight through the roof and toward the adjoining house.
This can make a significant difference where the patio sits directly outside living areas or large glazed doors.
Cooldek is a permanent solid roof.
That means the design needs to account for natural light through other factors such as:
patio height
roof orientation
rooflights
patio depth
attachment method.
If maintaining winter sun or daylight into the home is particularly important, Sunroof is often worth serious consideration.
Which Is Better in Rain?
Cooldek is a permanent solid roof, so it provides consistent weather protection without any moving parts.
Sunroof provides weather protection when the louvres are closed, but the way the system manages water is different.
During very heavy rainfall, performance can vary depending on drainage load and wind conditions.
The internal drainage system needs to manage the volume of water entering the roof, and in extreme conditions some splash may occur.
This doesn't mean Sunroof is unsuitable for Melbourne weather, but it is a different system from a permanent insulated roof and should be understood that way.
Which Is Quieter in Rain?
Cooldek will generally be quieter in rain.
The insulated panel construction naturally helps reduce rain noise compared with a metal louvre system.
For homeowners who are particularly sensitive to roof noise, or who plan to use the patio heavily during wet weather, this can be an important consideration.
Which Requires More Maintenance?
Both systems are relatively low-maintenance.
The main ongoing requirements are generally:
keeping the roof surfaces clean
washing down with mild soapy water where required
keeping gutters and drainage channels clear
removing leaves and debris.
Sunroof also contains moving components, so keeping the operating system clean and free from debris is important.
In practical terms, neither system should require excessive maintenance if it is looked after properly.
Which Is Better for Lights, Fans and Heatstrips?
Cooldek has the advantage here.
Because it has a clean ceiling-like underside, it is much easier and more cost-effective to mount electrical components directly to the roof system.
That includes:
lights
ceiling fans
heatstrips.
Sunroof is more limited.
On smaller Sunroof units there are generally no internal beams across the opening.
That creates a very clean, open appearance, but it also means there may be nowhere suitable to mount a ceiling fan.
Fans generally need an internal structural beam.
The same limitation can apply to heatstrips, although heatstrips can sometimes be mounted to a wall at an angle where permitted by the manufacturer.
This is an important design consideration if electrical fit-off is a major priority.
What Happens on Larger Sunroof Designs?
Smaller Sunroof structures generally have no internal beams across the opening.
Once the width becomes greater than around 6 metres, the roof may need to be divided into two operating sections.
At that point, a central structural beam is introduced to divide the two sections.
That changes both the appearance and the available mounting options.
The central beam can provide a location for items such as a ceiling fan or other suitable fittings, but it also adds structural complexity and cost.
Which Looks Better?
Both systems have a premium finish.
Sunroof has a very architectural look because of the opening louvre system and the clean underside without internal beams on smaller designs.
Cooldek has a refined ceiling-like finish and gives the outdoor area a more permanent room-like feel.
Neither product looks basic.
The better choice comes down to the style of the home and the type of outdoor space the homeowner wants to create.
Which One Costs More?
Sunroof is generally the more expensive option.
The motorised louvres, controls, structural requirements and operating components add cost compared with a fixed insulated roof.
Cooldek is usually considerably more cost-effective for a similar-sized area.
If you're considering Sunroof specifically, our Stratco Sunroof cost Melbourne guide explains realistic project ranges and why two similarly sized Sunroofs can still end up at different price points.
Which Is Better for Larger Areas?
Cooldek generally has the advantage for larger covered areas.
It can span further and is usually much more economical when the homeowner wants to cover a large entertaining space.
Sunroof becomes more structurally and mechanically complex as the size increases.
Once multiple operating sections and additional motors are required, the price can increase substantially.
If the goal is to create a large area for regular gatherings during both the day and evening, Cooldek can often be the more practical option.
When Does Cooldek Make More Sense?
Cooldek is often the better choice when:
the home receives a lot of summer sun
permanent shade is important
the patio will be used heavily during the day
the homeowner wants a large covered entertaining area
ceiling fans, lights or heatstrips are important
rain noise is a consideration
insulation is a priority
budget matters
larger spans are required.
For a home with an orientation that creates a lot of heat during summer, Cooldek can provide a very practical year-round solution.
When Does Sunroof Make More Sense?
Sunroof can be the better option where:
natural light is a major concern
winter sun into the living areas is important
the patio sits in a tight alcove
the homeowner wants to control airflow
the ability to open the roof is important
the architectural look of a louvre system is preferred
budget allows for a premium product.
In these situations, the ability to open the louvres can provide a benefit that a fixed roof cannot.
What About Patio Height?
Height matters with both systems.
A patio that sits too low can feel enclosed and may reduce natural light entering the home.
Both Cooldek and Sunroof can be raised using riser brackets where the property and engineering allow it.
Increasing the height can:
improve airflow
create more headroom
make the area feel larger
help maintain natural light.
However, riser brackets add structural complexity and can increase the project cost.
If you're comparing attachment styles and height options, our Stratco Outback Patio Melbourne guide explains fascia, riser bracket, flyover and freestanding options in more detail.
Attached or Freestanding?
Both systems can be designed around different property layouts.
Depending on the project, they may be:
attached to the house
partially attached
installed within an alcove
freestanding.
The attachment method can affect:
structural beams
column sizing
height
engineering
installation labour
overall cost.
The best configuration should be determined from the actual property rather than chosen from appearance alone.
Do Sunroof and Cooldek Patios Need a Building Permit?
Many patio projects in Victoria require a building permit.
Additional approvals can also depend on:
size
height
boundaries
site coverage
easements
planning controls
property-specific conditions.
For a detailed explanation, see our patio building permit Victoria guide.
If the proposed patio sits close to a side or rear boundary, our guide to building a patio close to the boundary explains the additional issues that may need to be considered.
What We Look at Before Recommending Sunroof or Cooldek
We prefer to start with the property rather than the product.
Before recommending one system over the other, we typically look at:
the orientation of the house
how much summer sun the area receives
how much winter sun you want to retain
available space
patio size
adjoining windows and doors
existing roof structure
desired height
attachment options
drainage
existing concrete
site access
electrical requirements
boundaries
easements
likely approvals
how the homeowner plans to use the space
budget.
Sometimes the answer becomes quite clear once those factors are considered.
A hot, exposed entertaining area that needs permanent shade may strongly favour Cooldek.
A tight alcove outside a living room where winter sun is important may strongly favour Sunroof.
The product should follow the problem you're trying to solve.
If you're also comparing installers, our guide to choosing a Stratco patio builder in Melbourne explains some of the questions worth asking before committing to a project.
Sunroof vs Cooldek: Which Should You Choose?
Choose Cooldek if your priorities are:
insulation
permanent shade
quieter performance in rain
easier installation of lights, fans and heatstrips
larger spans
strong value for a permanent roof
a clean ceiling-like appearance.
Consider Sunroof if your priorities are:
natural light
winter sun
adjustable airflow
opening the roof in good weather
a premium architectural appearance
greater control over the outdoor environment.
Neither product is automatically better.
The right choice depends on your property and how you want the space to perform throughout the year.
Frequently Asked Questions
Is Stratco Sunroof more expensive than Cooldek?
Yes, generally.
Sunroof includes motorised louvres, controls and additional structural and mechanical components, so it usually costs considerably more than Cooldek for a similar-sized area.
Is Cooldek better in hot weather?
Cooldek has a natural advantage because it is insulated and provides permanent shade.
Sunroof can still be comfortable because the blades can be partially opened to improve airflow while controlling sunlight.
Which is better for natural light?
Sunroof. The louvres can open widely to allow much more daylight through the roof and toward adjoining rooms.
Which is quieter when it rains?
Cooldek will generally be quieter because of the insulated panel construction.
Can you install a ceiling fan under a Sunroof?
Only where there is a suitable structural beam.
Smaller Sunroof units generally do not have internal beams, which can limit fan installation.
On larger Sunroofs divided into multiple sections, the central structural beam may provide a suitable mounting location.
Can heatstrips be installed under a Sunroof?
They may be mounted to a suitable structural member where available.
In some situations, a heatstrip may also be wall mounted at an angle in accordance with the manufacturer's requirements.
Which is better for a large patio?
Cooldek is generally more economical for larger areas and can span further.
Large Sunroof designs may require multiple sections, extra motors and additional structural framing.
Do both systems require maintenance?
Both are relatively low-maintenance.
Regular cleaning and keeping gutters and drainage paths clear of leaves and debris are important for both systems.
Can both systems be raised higher?
Yes. Both can potentially use riser brackets where additional height is required and the structural design allows it. This can increase the project cost.
Planning a Sunroof or Cooldek Patio?
If you're deciding between Stratco Sunroof and Cooldek, you don't need to choose the product first.
We can assess:
your home's orientation
summer heat
