Answers to some commonly asked questions.
Adjustable shade for the hottest parts of the day
Control direct sunlight to keep your outdoor area comfortable during peak heat.
Strong overhead sun is one of the main reasons outdoor areas heat up quickly in summer. A louvre roof gives you control over this by letting you adjust the angle of the blades to suit the time of day. When the sun is high, you can tilt the louvres to create full shade, preventing harsh light from hitting the space directly. As the sun moves, small adjustments help maintain a comfortable balance of brightness and protection without needing to relocate furniture or avoid the outdoors altogether.
This level of control is especially useful in Wellington, where the sun can feel intense even with a breeze. Instead of relying on fixed shade that doesn’t adapt as the day changes, a louvre roof lets you tailor the amount of cover moment by moment. You can keep the area darker and cooler during peak heat, then shift to softer, angled shade later in the afternoon. It’s a simple way to manage comfort while still keeping the space bright, inviting and usable throughout the day.
Better airflow with angled louvres
Use precise blade adjustments to release warm air and improve ventilation.
Managing airflow is one of the most effective ways to keep an outdoor area cooler in summer. When hot air gathers under a solid roof, the space can feel warm and enclosed, especially during the middle of the day. Airflow has a major impact on how an outdoor area feels in the middle of summer. Without a way for warm air to move out, it sits beneath the solid roof and creates a heavy, uncomfortable layer of heat. A louvre roof solves this by giving you control over how much air can pass through the space. By adjusting the angle of the blades, you create openings that release trapped heat and rising warm air while allowing fresh air to flow and move through. The SunPivot® system gives you precise control over blade positioning, so you can open them just enough to create ventilation while still maintaining shade. This balance helps your outdoor area stay cooler and more comfortable as temperatures rise.
This approach works particularly well during peak afternoon hours, when heat builds quickly on decks, patios and outdoor entertaining areas. Instead of blocking airflow the way a fixed roof can, angled louvres lift that trapped heat away and keep the space feeling open and breezy. You get the benefit of overhead cover without the enclosed feeling that often comes with solid structures. Whether you’re hosting guests or simply relaxing outside, this natural ventilation helps maintain a cooler, more refreshing environment throughout the hottest parts of summer.
Shelter from wind and rain
Glass sliding doors act as a reliable barrier against the elements, keeping your outdoor space comfortable even when the weather turns. They block wind, deflect rain and help soften outside noise, all while maintaining a clear view of your surroundings. This means you can enjoy your louvre roof area more often, without worrying about Wellington’s unpredictable conditions.
A modern, premium finish
Beyond their practicality, glass sliding doors add a sleek, contemporary touch that elevates the look of any outdoor space. Their clean lines and transparency create a seamless flow between indoors and out, making your deck or patio feel like a natural extension of your home.
Built for durability
Quality is key when it comes to doors that need to withstand outdoor use. With high-grade glass, durable tracks and wheels, and a strong magnetic latch system, these sliding doors are designed for long-term performance. They provide reliable operation even in gusty weather, ensuring your outdoor area remains both stylish and secure.
By combining weather protection with a sleek, architectural feel, glass sliding doors make your outdoor living space more versatile and welcoming. Whether you’re hosting friends or enjoying a quiet evening, they create an environment that feels both protected and polished.
Cooling benefits of a retractable roof
Open the roof fully to let heat escape quickly and create an open-air feel.
On very hot days, sometimes the quickest way to cool an outdoor area is to let the heat escape completely. With SunFold®, the louvre roof can retract to open the space up, allowing rising heat to disperse instantly. With SunFold®, the louvre roof can retract to create an open-air environment, allowing rising heat to disperse instantly rather than building up under a covered structure. This immediate release of warm air can cool the space more effectively than shade alone, giving you the freedom to reset the temperature of your outdoor area in seconds.
The flexibility of a retractable roof also means you can adapt the space to how you want to use it throughout the day. Keep the roof closed in the morning for softer light and protection, then open it later when you want more breeze or a clearer view of the sky. On particularly warm afternoons, retracting the roof prevents heat from lingering beneath the structure, helping the area stay comfortable for dining, hosting or relaxing. This ability to switch between shelter and open sky gives you a level of control that fixed roofs can’t offer, making your outdoor space far more adaptable to summer heat. It’s a flexible approach that keeps the space usable throughout long, hot summer days.
Material and colour choices that support summer comfort
Choose durable finishes and lighter Dulux® colours to influence surface warmth.
A louvre roof’s durability and finish play a role in how it handles strong summer conditions. COS louvre roofs are built from high-grade aluminium and finished with Dulux® powder coating, giving them long-term resistance to sun exposure and weather. While these materials are chosen for strength and performance, colour selection can also influence how warm the structure feels in direct sunlight. Lighter Dulux® colours tend to absorb less heat than darker shades, which can help reduce how hot the louvre surfaces become during the day. This gives homeowners another simple way to tailor the space to their comfort needs during peak summer temperatures.
High-quality aluminium construction
The structure is made from durable, powder-coated aluminium designed to perform well in strong sun and changing summer conditions.
Dulux® powder coat durability
The finish provides long-term protection against weather exposure, helping the roof maintain its appearance and performance over time.
Choosing colours that suit summer heat
Lighter colours generally absorb less heat than darker ones, which can help the louvre surfaces stay cooler under direct sun. With Dulux® powder coat options available, homeowners can choose a colour that suits both their home and their comfort preferences.
Custom designs to block strong afternoon sun
Position your louvre roof to shade the areas that receive the most intense sunlight.
Every outdoor space has its own sun pattern and in summer the angle of afternoon light can make certain areas far hotter than others. One of the advantages of a COS louvre roof is that each system is custom-made, allowing the structure to be positioned and designed in a way that directly responds to how the sun hits your home. Whether you choose a freestanding, wall-mounted or integrated setup, the roof can be tailored to provide shade exactly where it’s needed most, helping reduce the intensity of late-day heat.
A freestanding louvre roof can be placed anywhere in the garden to create a cooler zone away from the house, ideal for seating or dining areas that get strong overhead sun. Wall-mounted systems extend from the home to cover patios or decks that receive afternoon glare, providing reliable shade without blocking doors or windows. Integrated roofs blend into your existing structure and offer seamless, permanent cover for areas that need consistent protection. Because every COS roof is built to fit your space, you can choose the layout and orientation that best shields you from harsh afternoon sunlight, helping keep the entire area cooler and more comfortable during summer.
Creating a cooler outdoor living zone
Combine shade, airflow, and layout choices to keep the space feeling fresh and inviting.
A well-designed outdoor area should feel comfortable to use even when summer temperatures climb and a louvre roof makes this much easier to achieve. By combining adjustable shade, natural ventilation and the option to open the roof entirely, you can shape the space to suit the kind of environment you want at any moment. This flexibility means your outdoor area stays cooler and more inviting, whether you’re planning a long afternoon lunch, setting up a relaxing lounge spot or creating a family zone where kids can play out of the direct sun.
Small design choices also help contribute to a cooler atmosphere. Positioning furniture in shaded zones, choosing lighter outdoor fabrics and arranging seating where airflow naturally moves through all support the cooling benefits provided by the louvre roof. Because you can control how much light and air enters the space, you have the freedom to set up the area in ways that feel good to use throughout the day. It becomes a place where you can comfortably enjoy the warmer weather, knowing the environment can be adjusted whenever the heat intensifies.
Conclusion
Creating a cooler outdoor area during the height of summer comes down to having control over how much light, shade and airflow your space receives. A louvre roof gives you that flexibility, allowing you to adjust the environment as the temperature shifts throughout the day. With options to angle the blades, open the roof completely, choose colours that suit your comfort preferences and position the structure to block harsh afternoon sun, it becomes much easier to keep the space comfortable during even the warmest months. It’s a practical way to enjoy outdoor living in summer without worrying about rising heat or strong sunlight.

FAQs
Do I need to fully open the roof to cool the space down?
Not always. Tilting the louvres is often enough to release warm air and improve airflow. Opening the roof completely is helpful on very hot days or when you want a more open, breezy atmosphere.
Will choosing a lighter colour actually help with heat in summer?
Lighter colours tend to absorb less heat than darker shades, so the louvre surfaces can feel cooler when exposed to strong sun. We offers a wide range of Dulux® powder coat options if you prefer a lighter finish.
Can the roof be positioned to block afternoon sun?
Yes. Because each louvre roof is custom-made, it can be designed and oriented to provide shade in the areas that receive the strongest afternoon light.
Does airflow still work if the louvres are only slightly open?
Yes. Even small adjustments allow warm air to rise and escape, improving ventilation without losing the shade overhead.
Can I combine angled louvres with outdoor blinds in summer?
Yes. Many homeowners keep the louvres angled for airflow and lower the blinds only when needed for extra shade or privacy. It’s a flexible combination that still allows heat to escape.
