Read a detailed text description
The diagram branches from the shared name “pergola” into three overhead conditions: an open frame that lets rain pass, an operable cover whose state changes, and a continuous roof that collects water. Each branch then points readers to verify attachment, enclosure, services, structural actions, drainage and the local approval pathway.

Answer the installation-direction question first
For the query sens de pose de canisse sur pergola, do not begin with a universal north-south or reed-direction rule. Identify the exact mat, its intended exposed face and roll direction, the pergola's verified support lines, every free edge and the route for water and debris. Lay out the rolls so the manufacturer's fixing method can restrain both the field and perimeter without tying into gutters, wiring, louver blades or unverified decorative members. If those facts are absent, the defensible answer is to obtain the product instruction and redesign the support layout—not invent a spacing or direction.
Classify the cover before choosing details
Separate retractable fabric, removable natural canisse, fixed panels and planted canopies. A manually drawn or motorized textile has tracks, tension and operating states; a reed, split-bamboo or heather mat has distributed ties, exposed cut edges and wet organic material; a continuous panel collects rain; vegetation grows and changes over time. One category's fixing, drainage or wind rule does not transfer to another.
Government guidance on exterior overhangs, sunscreens and solar heat gain.
Check the existing frame and every interface
Record member sizes, condition, spans, connections, foundations and whether the original design included an added cover. Map fasteners, drainage, electricity, heaters, cooking appliances and moving components before work starts. A light dry roll can still create a broad wind-catching surface and retain water or debris. No generic tie interval or wind speed can replace the cover instructions, supporting-frame evidence and site wind basis.
Use the French canisse study within its boundary
An Indre government-hosted college study shows one bamboo-or-heather canisse proposal laid over an existing transparent canopy and fixed to its frame. The same document flags wet-period rot or fungal growth and replacement after some years. This is evidence that moisture and replacement access belong in the brief; its project sketch and approximate five-year replacement note are not a universal installation detail, warranty or service-life value.
A site-specific French college adaptation study showing bamboo or heather canisses placed over an existing transparent canopy and fixed to the existing frame, with wet-period rot or fungal growth and eventual replacement identified as constraints. Its layout and approximate replacement timing are not a universal installation detail or service-life claim.
Keep shade separate from rain protection
Canisse, open-weave fabric and planted cover can interrupt solar radiation while still admitting wind-driven rain, drips and debris. Do not describe them as waterproof without assembly-specific test evidence. Preserve drainage and overflow paths below or around the cover, avoid concealed wet contact, and provide a drying and inspection condition. Water pockets, persistent sagging, staining, fungal growth or blocked outlets require correction before continued use.
Plan wind, weather and removal states
Write the installed, retracted or removed state for normal use, forecast wind, storms, snow, freezing conditions and prolonged vacancy. Retractable systems need documented control and power-failure behavior; removable mats need an accessible release and storage plan that does not require unsafe roof access during an event. Stop use for loose ties, torn edges, progressive lift, distorted supports, jammed tracks or any cover that cannot drain and dry as intended.
Departmental wildfire guidance stating that an attached pergola or awning covered with fabric, canisse or vegetation can ignite and promote fire spread to a dwelling. It is a French wildfire-vulnerability source, not a material fire classification, global clearance rule or product test.
Treat fire and hot components as site questions
Bouches-du-Rhône wildfire guidance states that a pergola or awning covered with fabric, canisse or vegetation can ignite and promote fire spread to a dwelling. Apply that statement only to its French wildfire-vulnerability context; it is not a global fire rating or clearance. Check the local hazard rules and verified clearances from heaters, luminaires, cooking appliances, chimneys and electrical equipment, and keep dry debris from accumulating.
Verify planning and appearance changes locally
France's Service-Public guidance makes pergola authorization depend on the local plan, location, project classification and footprint. It does not decide whether one removable mat changes one existing approval. Record the before-and-after configuration and ask the competent authority when the cover alters appearance, roof state, attachment, area or use; do not transfer French thresholds outside France.
Official French planning guidance explaining that the applicable filing depends on local planning rules, location, project classification and footprint. It does not determine whether adding a removable shade mat changes a specific project's authorization and does not apply outside France.
Retractable and canisse cover FAQ
Which way should canisse run? Along the verified support and restraint layout required by the exact product, not a universal compass direction. Can it make a pergola waterproof? Not without assembly-specific rain evidence and a continuous drainage design. Is natural canisse automatically safer or more sustainable? No: origin, treatment, durability, replacement, fire exposure and end-of-life evidence must be checked separately.
Choose the side panel by the job
Start with the occupied position, season and problem. An open solar mesh may preserve outward view while reducing some direct sun; a privacy textile can block views but also daylight and ventilation; insect mesh is not rain protection; a louver, glass panel or dense screen creates different sightlines, edges and loads. Rank solar control, privacy, insects, wind, rain and view rather than assuming one panel optimizes all six.
Official abstract establishing a lifecycle framework from briefing and design through maintenance, replacement, reuse and disposal.
Classify the assembly and every operating state
Separate loose curtains, tensioned or zip-guided mesh, sliding or fixed louvers, rigid transparent panels and vegetation. Record the exact deployed, partly deployed, retracted, removed and power-loss states, including which rails, cassettes, bottom bars, locks and sensors act in each state. Evidence for one product size, mounting arrangement or state does not automatically cover another.
Map sun, view and privacy before choosing opacity
Plot the sunward side and occupied eye positions for the relevant hours and seasons, then mock up panel height, openness and overlap. U.S. Department of Energy guidance supports exterior sunscreens as a way to reduce unwanted solar heat gain at building fenestration; it does not prove a universal pergola cooling value, fabric openness or comfort outcome. Verify performance for the exact screen, orientation and use instead of converting marketing percentages into whole-space results.

Treat a deployed screen as a changed wind condition
A side panel can turn an open bay into a larger wind-catching area and redirect actions into tracks, posts, beams, anchors, foundations and the existing building. Eurocode 1 identifies wind actions as a structural design action, but it supplies no product capacity or nationally adopted project value by itself. Use the current local design basis and the exact configured assembly; a screen-component rating is not a rating for the complete pergola, substrate or soil.
Keep rain, drainage and ventilation independent
A side screen can reduce some wind-driven rain without making an outdoor pergola a waterproof room. Preserve roof outlets, overflows, thresholds, post drains and drying paths; avoid a bottom rail or seal that traps water against paving, cladding or timber. Check splash, rebound, panel runoff and condensation in the deployed state. Ponding, concealed overflow, persistent wet contact, icing or water near electrics requires stop-use and correction.
European framework for actions including self-weight, imposed, snow and wind actions.
Measure the opening and all interfaces
Measure clear width at the top, middle and bottom, clear height at several positions, diagonals, post plumb and available cassette, track and bottom-bar zones. Record expected frame movement, door swings, step-free routes, guards, egress, handles, furniture, gutters, wiring, controls and cleaning access. Confirm who owns reinforcement, penetrations, seals, electrical isolation, commissioning and future replacement before ordering; a nominal bay size is not an installation drawing.
Write an operating and maintenance matrix
For normal use, forecast wind, storms, snow, freezing conditions, power failure and vacancy, state whether each panel stays deployed, retracts, unlocks or is removed, who acts and how the action remains safely accessible. Inspect fabric edges, stitching, guides, fasteners, seals, drainage and controls at product- and exposure-specific intervals. Uneven travel, edge abrasion, flutter, lifting, water pockets, distorted tracks or repeated motor trips are stop-use signals until the cause is resolved.
Official New Zealand guidance stating that the pergola exemption covers simple-framed, unroofed structures; adding a roof can move the work outside that exemption.
Recheck the approval boundary when enclosure changes
New Zealand MBIE guidance illustrates a narrow distinction: its consent exemption is for simple-framed unroofed pergolas, while adding plastic covering to create a closed roof and walls leaves that exemption. England's householder permitted-development guidance has different categories and constraints. Neither example decides a project elsewhere, and a movable screen is not automatically a wall or veranda; give the competent authority before-and-after drawings showing roof, sides, doors, use, footprint, height and attachment.
Overhead retractable cover or side screen: classify before you quote
“Retractable pergola shade” describes at least three different products: an overhead fabric cover that rolls out over the frame, a retractable awning mounted on or beside the frame, and a vertical deployable screen. Decide which one is being bought before comparing price, colour or wind wording. Public German standards metadata for DIN EN 13561 identifies pergola awnings inside the external-blinds-and-awnings product family, and Regulation (EU) 2019/1188 lists nominal and safety pressure classes for that product; both describe the product and its declared class. Neither states the capacity of the pergola frame, its fixings, its footings or the ground, and neither decides a local approval. Record the product family, the fixing position—overhead, side or freestanding—the retracted and deployed geometry, the drive, the stowed storm position and the exact document that declares any class.
England-only technical guidance distinguishing ground level from added decking and defining a raised platform as more than 0.3 metres; verandahs, balconies and raised platforms are excluded from the cited householder permitted-development classes. It does not decide whether a pergola or terrace project is lawful, remove building-regulations or other-consent checks, or apply elsewhere in the UK.
What an overhead retractable cover changes
A deployed overhead cover adds a broad lifting and catching area that an open lattice does not have, and even a retracted cassette or rolled bundle changes the exposed area, the self-weight and the drainage path. Rain: an overhead cover intercepts water that would otherwise pass through, so the top only becomes water-shedding when the system has a continuous collection, discharge and overflow path; without it the water arrives at the frame, the wall, the paving or a neighbour. Snow and ice: slack or part-retracted fabric can hold snow or ice where open rafters would shed it, so the permitted winter state is a product and site decision rather than a default. Operation: for awning-type products the high-wind safe state is usually stowed, which is the opposite of a fixed roof, and the permitted state, sensor logic, power-loss position and manual override must be stated and recorded for each hazard. Enclosure: a retractable overhead cover is neither automatically an open pergola nor a closed room, so keep before-and-after drawings for roof state, sides, use, footprint, height and attachment. Note that DIN EN 13561 metadata and EU awning wind classes cover the product, not the supporting structure, and that IEC 60335-2-97 addresses the safety of drives for awnings, blinds and similar equipment rather than the frame.
Pergola side-panel FAQ
Do side panels stop wind? They can alter airflow, but only configuration-specific evidence can establish usable operating limits. Do they make a pergola waterproof? No—not without complete rain, drainage and interface evidence. Can panels be added later? Only after rechecking the frame, tracks, connections, anchors, water paths, access, electrics and approval basis. Which opacity is best? There is no universal value; test the needed balance of sun, view, privacy and ventilation at the actual position.
Binding EU delegated regulation establishing wind-load performance classes and explicitly distinguishing pergola awnings. Product classes do not establish site wind speed, supporting-structure capacity, anchorage or project approval.
Keep drive evidence within its boundary
IEC 60335-2-97 can be relevant to the safety of an electric awning drive, but it does not establish fabric strength, track anchorage, wind operating limits, drainage or the structural capacity of the supporting pergola. Procurement should keep the drive, moving fabric assembly, controls, frame and site installation evidence distinct and then verify their interfaces.
