Bioclimatic pergola with adjustable aluminium louvres – flexibly manage sun, shade, airflow and rain protection
The Bloomcabin bioclimatic pergola is designed for terraces where a fixed roof would restrict how the space is used. Its adjustable aluminium louvres can be opened, tilted or closed according to the sun and weather. This means the area is not limited to one roof setting: it can feel open and airy, be shaded precisely, or offer greater protection in rain. This flexibility is particularly useful when the terrace is used differently from breakfast through to dinner.
The current range covers 9–24 m² and has an overall height of around 250 cm. High-quality aluminium profiles, integrated rainwater drainage and a choice of RAL colours shape the product concept. Optional automation and side solutions allow the pergola to be matched to the desired operating comfort and to privacy, sun or wind protection.
Before configuring, it is worth assessing the terrace carefully. Alongside the path of the sun, consider the prevailing weather side, the position of house entrances and windows, existing drainage and the space needed for furniture. If a motor and LED lighting are required, plan the electricity connection and cable route before the terrace finish or adjoining areas are completed. Before ordering, ask a perit to confirm the Planning Authority classification for the specific pergola and site, including its footprint, height, enclosure, land designation and existing permit conditions. A removable kit or domestic garden location does not by itself establish permission. Bloomcabin Malta.

Adjustable louvres adapt the terrace to time of day and weather
Unlike a fixed pergola roof, the aluminium louvres can be opened, tilted or closed. An open position admits light and retains an unobstructed view upwards. Tilting reduces direct sunlight without closing the roof completely. Closed louvres create a more sheltered area. The most comfortable setting depends on the time of day, sun angle, temperature and how the terrace is currently being used.
Partly open louvres provide shade while allowing warmed air to escape upwards. This is especially pleasant in seating and dining areas, where a permanently closed roof can quickly feel confining on warm days. Closed louvres provide more protection from direct sun and rain. As the pergola remains an outdoor structure, sensitive items should still be stored suitably for the weather.
Optional motorisation makes regular adjustment of the louvred roof easier. Depending on the configuration, selected side elements can also be included in motorised operation.

Robust aluminium profiles, integrated drainage and clean-lined design
The pergola is made from high-quality aluminium profiles and combines crisp lines with manageable maintenance. The structure is not maintenance-free: surfaces, connections and moving parts should be inspected regularly, with dirt removed early. Careful site planning also ensures that gutters, louvres and side elements remain accessible later.
Rainwater is routed within the structure, so visible gutters do not unnecessarily interrupt the clean overall design. However, the integrated routing does not automatically solve drainage for the property. During planning, establish where water will exit and how it will be directed away from façades, foundations, terrace surfaces and frequently used walkways. Connecting to the existing drainage plan is therefore part of site preparation.
RAL colours allow the frame to be coordinated with windows, doors, the façade, pool area or terrace materials. For a calm architectural effect, the colour can echo existing metal features. A deliberate contrast, however, highlights the pergola as an independent design element. Do not judge the choice from small colour samples alone: light, shade, adjacent surfaces and the size of the structure affect how bright or dominant a tone appears outdoors.

Plan the louvred roof first, then choose suitable side protection
Adjustable louvred roof
The adjustable louvred roof determines how much light enters from above and how effectively warm air can escape. First consider how the terrace will mainly be used and at which times shade is needed. You can then decide specifically which sides would genuinely benefit from extra sun, privacy or wind protection.
Outdoor options
Optional screens, side panels or glass walls serve different purposes. Screens suit flexible sun and privacy protection, while glass walls preserve the view and can reduce wind entering from the side. Panels create more enclosed areas. As every solution affects light, views, air movement and routes around the pergola differently, each side should be considered individually. Identical equipment all around is not automatically the most functional choice.

Choose the right roof setting for every use
For plenty of daylight and an open view above, the louvres can be opened wide. As the sun moves onto the seating area, a tilted position can reduce direct sunlight while air continues to escape upwards.
During a shower, the louvres can be closed. If low sun, overlooking or side winds are disruptive, carefully positioned side elements can complement the roof without unnecessarily enclosing the other sides.
The pergola extends usable outdoor living space, but remains an uninsulated outdoor area even with closed louvres and side elements.
Four ideas for a flexibly designed terrace area
Dining area
Create a fixed dining spot with controllable shade and optional LED lighting.
Garden lounge
Arrange a lounge with low seating and adjust the louvred roof to suit light and weather.
Wellness area
Pair a hot tub or relaxation area with screens or side elements.
Terrace for social gatherings
Design a flexibly shaded dining and seating area for shared meals and relaxed evenings.
Louvre settings, side elements and orientation should be based on the actual conditions on the terrace. Observe when direct light reaches the seating area, the directions from which rain and wind often arrive, and which views should remain open. Reflections from light façades or large glazed areas can also change how light is perceived. This site assessment is more meaningful than a configuration based solely on compass direction.
Changeable weather
In spring and autumn, sun, wind and showers can change quickly. The adjustable louvred roof enables a prompt response without repositioning separate sun protection. For permanently exposed sides, however, a targeted side solution is often more useful than enclosing the pergola completely.
When choosing the orientation, also consider doors, full-height windows, roof overhangs and usual routes between house, garden and terrace. Posts and side elements should neither narrow an important passage nor unnecessarily obstruct views from frequently used rooms. When positioned close to the house, check that windows and doors can still be operated fully and that façade areas remain accessible for later maintenance.
Plan side elements where they serve a clearly identified purpose. On the weather side, side protection may be the priority; towards neighbours, privacy; and on a sunny side, protection from low-angle light. Deliberately open sides, by contrast, retain the connection to the garden, clear routes and natural air movement.
South- and west-facing terraces
On south- and west-facing terraces, the preferred time of use should determine the configuration. Check at the specific site how light falls on seating and adjacent glazing in the morning, afternoon and evening. This shows which louvre setting shades the used area from above and where additional side sun protection may be useful.
Assess shade not only in the centre of the pergola. Table surfaces, individual seats and walkways can be affected differently according to the sun angle. What matters is shading the areas actually used, not merely the louvre position across the entire roof.
Include adjoining interior spaces in the assessment as well. Even where the seating area is shaded, light can reach full-height windows or cause reflections there. Compare the effect from the terrace and from frequently used rooms before deciding on orientation and side equipment.
Power connection and LED lighting
For motorisation and integrated lighting, the connection point and cable route must be set early. Cables should suit the chosen equipment and final post layout, so they do not later have to run visibly across the finished terrace surface.
Connection and transition points must remain accessible for inspection and servicing despite discreet cable routing. Coordinate their position with foundations, drainage, side elements and planned furniture before finishing the terrace or façade.
Outdoor electrical work must be carried out professionally and in line with local requirements. In Malta, arrange fixed wiring through a REWS-authorised professional with the appropriate scope, and confirm testing and certification for the installation. Decide in advance which equipment will be connected and where controls will be easy to reach in everyday use.
Drainage and ground conditions
When the roof is closed, rainwater is drained within the structure. Site planning must consider the complete water route: from the louvred roof through the integrated routing to the point where water joins existing terrace drainage, infiltration or another intended solution.
Check the fall, adjacent paving edges, planting beds and possible obstructions at the planned outlet. Water must not remain there, run back towards the façade or cross a frequently used path. The onward route should therefore be clearly established before installation.
Installation requires a level fixing surface suitable for the structure. A finished terrace covering alone does not reveal how the base is built. Check the construction, fixing points and heights, along with existing cables or drainage elements, before final drilling and installation positions are determined.
Size, furniture, side elements and technical equipment should be planned together. Even a generous area can feel cramped when chairs, doors, screens and walkways compete for the same space. The deciding factor is therefore not only the pergola’s external dimensions, but the usable area between posts, furniture and moving elements.
Furniture at the right scale
A dining table needs not only its own footprint, but also room for chairs to be pulled back and for people to pass behind them. A lounge with deep seating often uses more continuous floor area, but needs different routes. Also consider serving routes from the house, access to the garden and operation of possible side elements. Furniture should be comfortable to use without touching posts, glass surfaces or screens.
A scaled plan shows whether chairs can be pulled out fully, passageways remain clear, and doors or side elements can operate without conflict. Draw not only furniture outlines, but also the space needed when furniture is in use. This reveals overlaps before the pergola size is chosen.
Alongside tables, chairs, a lounge or hot tub, include planters, a barbecue and storage furniture intended to remain under or directly beside the pergola. Then check which areas must remain clear for access to the house, garden and technical components.
Sun angle, not only compass direction
Roof louvres mainly influence light entering from above. Low morning or evening sun, however, can reach seating or adjoining rooms below the roof edge. Consider not only compass direction but also seating positions, views and the times when the terrace is actually used.
The louvred roof and screens have different roles. The roof shades from above and can be opened for air exchange; a screen can reduce light or overlooking from the side. A targeted combination is more useful than keeping the roof permanently closed because of side glare.
Observe the sun’s path at usual times of use. Photos taken at the site in the morning, at midday and in the evening help record shade lines, reflections and side light. This makes it easier to establish which side genuinely needs a screen and which view should deliberately remain open.
Screens or glass walls?
Screens provide flexibly operated sun and privacy protection. Glass walls preserve the view and can reduce side winds, but remain permanently in place and must be accessible for cleaning. When choosing, consider the protective effect, openness, maintenance needs and the desired connection between terrace and garden.
Not every side needs the same equipment. More privacy may be useful towards a road or neighbouring property, while a sheltered garden side is better left open. Ensure side elements do not obstruct important routes, views or the desired airflow.
For each side, note which problem should be solved, when it occurs, and whether a permanent, transparent or flexibly operated solution is wanted. This provides a basis for comparing screens, glass walls and panels without planning several elements for the same purpose.
Motorisation and controls
A motorised roof should be operable from a position where the louvres are clearly visible. LED lighting should also reflect intended use: lighting over a dining table serves a different purpose from even illumination of the whole pergola area.
Before ordering, decide which components should be motorised and which manually operated. This allows the power supply to be matched to the selected equipment. Include the roof, lighting and automated side elements in one coordinated control concept.
Controls should be easy to reach from the usual seating area and clearly assigned. Open doors, chairs or side elements must not block access. Their final position can therefore only be determined sensibly once furniture and walking routes have been planned.
Foundations, drainage and maintenance access are much harder to change later than furniture or decoration. These points should therefore be decided early. Keep gutters, louvres, surfaces and side elements accessible so inspection, cleaning and servicing can be carried out without unnecessary obstacles.
Keep drainage inspectable
Leaves, pollen and other deposits can affect integrated water routes. Gutters and outlets should therefore remain accessible and be checked regularly, particularly near trees. Loose dirt is easier to remove before it compacts and obstructs drainage.
Observe where water actually flows after leaving the outlet. Falls, paving joints, edges or low points can alter the intended route. The drainage connection should be arranged to avoid splashback on the façade and lasting moisture around posts or fixings.
After installation, check in suitable weather that the intended drainage works in practice. Later changes to paving, beds or edging can affect the water route and should not be made without considering their impact on drainage.
Maintenance access
Louvres, gutters, screens and glass surfaces should be easy to reach for inspection and cleaning. Use gentle cleaning methods suitable for aluminium surfaces, and avoid tools that could damage the coating. Do not force blocked moving parts.
Large furniture and heavy planters should not permanently obstruct maintenance and service areas. Leave enough space in front of screens, by posts and beneath drainage points for occasional work. Take this access into account when planning the furniture.
Regular visual checks help identify leaves and other deposits in water routing or in the movement areas of louvres and side elements early. After a long period of non-use or exceptional loading, an additional check is advisable before operating moving components again.
Check the configuration before ordering
Finally, compare the external dimensions, usable internal area and intended site. Add posts, furniture and the necessary circulation space to the plan alongside the roof area. This shows whether the pergola covers the desired terrace zone without restricting entrances to the house or garden paths.
Compare the selected version with every fixed feature at the site: façade, doors, windows, roof overhangs, paving edges, drainage and power supply. Differences are far easier to accommodate before ordering than after preparing the base.
Then record the chosen RAL colour, roof operation, side elements, lighting and automation together. This overview helps coordinate design, technical preparation and later use, and prevents individual options from being planned in isolation.
Allow for later changes
Outdoor furniture and habits can change over time. A clearly organised area that is not over-furnished makes it easier later to replace a dining table with a lounge or add more seats. Walkways and maintenance areas should remain clear regardless of the chosen arrangement.
Where the selected equipment allows different furniture layouts, power connections and lighting should not be directed solely towards a single piece of furniture. A flexibly usable floor area supports later changes between seating and dining zones without altering the pergola structure.
Permanent elements such as glass walls require more careful planning than movable furniture. Check how they affect views, cleaning, walking routes and airflow. Screens respond more flexibly to changing sun or privacy needs, but fulfil a different role. What matters is the specific requirement on each side.

FAQ – bioclimatic pergola
What makes a pergola bioclimatic?
Its defining feature is the adjustable louvred roof. Different louvre positions influence how much direct light reaches the terrace and how open the roof remains for air exchange. In the closed position, it offers greater protection from sun and rain. The term does not describe a fully climate-controlled room, but an outdoor structure whose roof can be actively adapted to different situations of use.
How do I choose the right pergola size?
Start with the actual terrace dimensions and planned furniture. Also draw chairs pulled out from the table, walkways, doors, posts and movable side elements onto a scale plan. The right size is the version in which these areas remain comfortably usable without overlaps.
What should be considered when positioning it directly by the house?
Check façade openings, roof overhangs, outdoor lights and the usual routes between house and terrace. Windows and doors must remain fully operable. Include the planned drainage, power supply and access for future maintenance when selecting the site.
Can the roof be motorised?
Yes. Motorised control is optionally available for the louvred roof and selected side elements. The power supply, cable route and control position should be decided before the terrace finish or adjoining areas are completed.
Must every side have the same equipment?
No. Screens, glass walls and panels should be used only where they fulfil a specific purpose. Depending on the side, sun protection, privacy, views or reducing side winds may have different importance. A deliberately open side can retain routes, views and airflow.
What needs to be planned for on-site rainwater drainage?
Water routing is integrated into the pergola structure, but ends at an outlet at the site. From there, water must be guided onwards to suit the fall and existing drainage. It must not flow towards the façade, fixing points or across frequently used routes. Gutters and outlets should remain accessible for inspection.
How are aluminium frames and louvres maintained?
Remove leaves and loose dirt regularly, using gentle cleaning methods suitable for aluminium surfaces. Check gutters and movement paths at the same time. Blocked louvres or side elements should not be operated forcibly; first check for dirt, ice or other obstructions.
What information helps prepare for a consultation?
Useful information includes terrace dimensions, the position of doors and windows, planned furniture, and details of the sun’s path, weather side and desired side elements. Add the intended water outlet, power supply and preferred RAL colour. Photos and a scale plan make it easier to coordinate the configuration.
