Question 1

What is a bioclimatic pergola?

Accepted Answer

A bioclimatic pergola (also called a louvered pergola or louvre roof) is an outdoor structure with adjustable aluminum blades that rotate to control sunlight, shade, and ventilation. The term 'bioclimatic' refers to its ability to adapt to changing weather conditions — you can open the blades for ventilation on a warm day, angle them for shade in summer, or close them completely for waterproof protection in rain. KAKADU bioclimatic pergolas feature blades that rotate 0°–135° with integrated drainage channels.

Question 2

What is the difference between a louvered pergola and a bioclimatic pergola?

Accepted Answer

There is no product difference — 'louvered pergola' is the common term in North America (using 'louvered' with American spelling) while 'bioclimatic pergola' is the standard term in Europe and the Middle East. Both refer to the same product: an aluminum pergola with rotating blades. In Australia and the UK, you'll also hear 'louvre roof' (British spelling) and 'opening roof'. KAKADU uses all these terms to serve global markets.

Question 3

What is an opening roof pergola?

Accepted Answer

An 'opening roof' is the term commonly used in Australia and New Zealand for a pergola with a roof that can open — either by rotating louvers (bioclimatic/louvered pergola) or by sliding the entire roof panel (retractable pergola). The term emphasizes the key benefit: the ability to open your outdoor space to the sky. KAKADU offers both louvered opening roofs and retractable opening roof systems.

Question 4

What is the difference between manual and motorized louvered pergolas?

Accepted Answer

Manual louvered pergolas use a hand crank mechanism to rotate the blades — they are cost-effective and reliable with no electrical requirements. Motorized louvered pergolas use a tubular electric motor (typically Somfy or equivalent) controlled by remote, wall switch, smartphone app, or smart home system. Motorized models can also integrate wind and rain sensors for automatic blade adjustment, making them ideal for larger installations and premium residential or commercial projects.

Question 5

What is a retractable pergola?

Accepted Answer

A retractable pergola features a roof made of aluminum slats that slide and fold together, allowing you to completely open the roof to the sky or close it for full shade and UV protection. Unlike louvered pergolas where blades rotate in place, retractable pergolas physically move the entire roof panel to one side. They are available in pure retractable (sliding only) and adjustable & retractable (2-in-1: blade rotation + sliding) configurations.

Question 6

What is the difference between retractable and louvered pergolas?

Accepted Answer

Louvered pergolas have blades that rotate in place (0°–135°) to control light and ventilation while the roof structure stays fixed. Retractable pergolas have a roof that physically slides and folds to one side, creating a fully open sky experience. Louvered pergolas excel at fine-tuned climate control; retractable pergolas excel at the open-air experience. The 2-in-1 adjustable & retractable model combines both functions.

Question 7

What is a fixed roof pergola?

Accepted Answer

A fixed roof pergola has a permanent, non-adjustable roof structure. The roof is typically made of insulated aluminum panels or polycarbonate sheets. Fixed roof pergolas are the most cost-effective option and are ideal for projects where a permanent shade structure is preferred. They come in perforated aluminum panel designs (custom patterns for decorative light-and-shadow effects) and fixed blade designs (permanent angled blades for continuous shade).

Question 8

What is a patio cover and how does it differ from a pergola?

Accepted Answer

A patio cover is a broad term (common in North America) for any structure that provides shade over a patio. A pergola is a specific type of patio cover with an open or adjustable roof structure. Traditional pergolas have fixed open beams; modern aluminum pergolas (like KAKADU's) have adjustable louvers or retractable roofs. When people search for 'patio cover,' they are often looking for what we call a louvered pergola or retractable pergola.

Question 9

What is the maximum size for a pergola?

Accepted Answer

Standard single-module pergolas span up to 6m × 4m. Multi-module configurations can extend much wider — our louvered systems support 6-post configurations up to 8m wide, and linked modules can cover dozens of meters for commercial installations. Custom sizes are available for architectural projects. Contact our engineering team for project-specific structural calculations.

Question 10

Can pergolas be installed against a wall?

Accepted Answer

Yes. We offer three main installation layouts: Free Standing (classic 4-post standalone for gardens and courtyards), Wall Mounted (2-post attachment to an existing wall, extending shade over patios and terraces), and Multi-Module (multiple units linked in series for restaurants, pools, and commercial terraces). Custom layouts are also available for architectural projects.

Question 11

What materials are used in KAKADU pergolas?

Accepted Answer

All structural components use 6063-T6 aluminum alloy with powder-coat finish. Hardware is SS304 stainless steel. Blades range from 140mm to 300mm depending on the model. Motors are premium brands such as Somfy. LED lighting options include warm white (3000K), cool white (6000K), and 24V RGB ambient strips.

Question 12

Are aluminum pergolas waterproof?

Accepted Answer

Yes. KAKADU louvered pergolas are fully waterproof when the blades are closed. The interlocking blade design creates a sealed roof surface, and integrated drainage channels within the blades route rainwater through the posts and into the ground. Our pergolas have been tested to withstand heavy rainfall and are suitable for all climate zones. The waterproof rating depends on proper installation — we provide detailed installation guides and can connect you with certified installers in your region.

Question 13

How long do aluminum pergolas last?

Accepted Answer

KAKADU aluminum pergolas are designed to last 20–30+ years with minimal maintenance. The 6063-T6 aluminum alloy does not rust, corrode, or degrade under normal weather conditions. The powder-coat finish is rated for 15–20+ years before any refinishing would be considered. Moving parts (motors, gears) typically last 10–15 years and can be replaced if needed. This makes aluminum pergolas a significantly longer-lasting investment compared to timber pergolas (which require regular staining and are susceptible to rot and termites).
