Louvred (bioclimatic) or fabric-roof pergola?
Both structures shade the same terrace, but in different ways. A louvred roof gives you gradual control over light and airflow; a fabric roof keeps out rain and direct sun at a lower entry price. This comparison walks through which choice fits which need.
The two types in a nutshell
A louvred pergola, commonly called a bioclimatic pergola, has a roof of tilting aluminium louvres. The louvres tilt steplessly with a motor, so you control how much light and air reaches the space below; when it rains, the roof closes watertight. In the RGM Italia range this is the Climax series.
A fabric-roof pergola uses a textile canopy stretched over an aluminium frame. The roof is either fixed and tensioned or motor-retractable, depending on how much shade and open sky you want. This group includes the Eterea, Eterea Moove, Greta and Pavillon. The entry price is typically lower than in the louvred category.
Both are serious, permanent terrace covers, not seasonal sunshades. The difference lies in how the roof works and in how precisely you want to manage light and air.
Louvred (bioclimatic) pergola: precise control of light and air
The Climax louvres tilt between 0° and 125° (0°–100° on the Climax Smart version). Closed, the roof is a watertight surface, and the 16×16 cm posts with their integrated rainwater chamber drain the water away. Open, warm air escapes upward; partly open, the roof filters direct sun while the space ventilates.
This gradual control makes a louvred roof a full-season cover. From spring to autumn the same terrace handles the harsh midday sun, the slanting afternoon light and the cooler evenings, when the roof closes into a wind-sheltered space. For hospitality it means the tables stay usable almost regardless of the weather.
The structure is rigid and can be built wall-mounted or free-standing. In return, this is the premium tier: the motorised louvre roof and the heavy-duty profile system cost more than a tensioned canopy. If you want to adjust light and airflow day by day and hour by hour, that price is worth paying.
Fabric-roof pergola: shade and rain protection at a better price
Fabric-roof models shade and keep out rain with a textile canopy tensioned over an aluminium frame. The Eterea works with a fixed tensioned roof; the Eterea Moove and the other models offer a motor-retractable canopy, so the roof can be opened fully or in part.
The roof is gently curved so water runs off reliably, with drainage handled by a Ø50 mm pluvial pipe integrated into the support posts (piantone). The textile roof is not a tilting louvre, so it does not adjust light in steps; instead, retracting or extending the canopy sets how much open sky stays overhead.
The entry price of a fabric-roof pergola is more favourable than that of the louvred bioclimatic version. Where the goal is dependable shade and protection against summer showers, with no need to tilt the roof gradually, the fabric-roof solution is a proportionate investment.
Which one fits what?
A louvred (bioclimatic) pergola is worth choosing if you want a permanent, watertight roof on which you can precisely control light and airflow, and if you use the terrace all season, perhaps as a hospitality space. Larger spans and continuous, intensive use also favour this category.
A fabric-roof pergola is the logical choice when the main need is shade and rain protection, the budget is tighter, and use is concentrated in the warmer months. On a residential terrace, where you want summer shade rather than a tilting louvre roof, the fabric-roof model usually meets the need.
Span and the installation site also shape the decision. Exactly how the two posts, the column layout and the roof structure fit a given terrace is something we can pin down during the on-site survey.
What both types share
Whichever you choose, the same material and manufacturing quality stands behind it. Both series are made of UNI 6060 aluminium, the joints use INOX stainless fasteners, and the finish is QUALICOAT-certified powder coating, rated for outdoor exposure.
In both cases the open pergola can be enclosed into a four-season space: with glazing, the Mirada louvred side wall or the Winterly enclosure system. Comfort is rounded out by motorisation and integrated LED lighting, so the space stays usable in the evening and in cooler weather.
In other words, the choice is not about quality but about how the roof works and the price level. You will find the details on the Climax (bioclimatic) and the Eterea, Greta (pergola awnings) model pages, and we can tailor the decision to your terrace in a concrete quote.
