Building façades in Morocco: cladding, curtain walling, fire safety and heritage rules

A façade in Morocco has to satisfy several regulations at once. The energy code RTCM (Decree No. 2-13-874) counts walls and glazing in the envelope balance; the fire regulation (Decree No. 2-14-499) governs how fire may spread across the building; and in medinas or near listed monuments, Law 22-80 subjects works to authorisation. Three façade products carry mandatory standards: coated steel sheet (NM EN 10346), metal-faced sandwich panels (NM EN 14509) and glazed assemblies (NM ISO 9051). Curtain walls, façade paints and reaction to fire follow homologated standards.

Scope

This page considers the outer skin of the building beyond plain render: ventilated cladding (stone, composite panels, metal), curtain walls and glazed façades, sandwich-panel façades on industrial buildings, façade paints and coatings, and the refurbishment of existing façades. The windows themselves are covered on the aluminium joinery page.

Work is framed by the architect's façade details and the approval of samples, then carried out once the structure and masonry are accepted. It ends with the joint and sealing checks and the cleaning of the façade before scaffolding comes down.

Who does what

PartyRole
ArchitectDesigns the façade, obtains heritage authorisation where needed, draws the details and approves samples and trial panels.
Façade engineer or structural consultancy (BET)Checks brackets, anchors and the façade's resistance to wind and seismic movement; reviews the façade contractor's calculations.
Façade contractorProduces shop drawings, installs the system as approved, and provides product certificates and test evidence.
Fire safety reviewer or inspection bodyConfirms that cladding and insulation comply with the fire regulation for the building class.
Client (owner)Validates the appearance and budget, and keeps the maintenance instructions for cleaning and sealant renewal.

Inspection milestones

  1. Architectural details and coordination of openings Good practice
    Façade details coordinated with structure and openings: anchors, joints, sills, drips and fire stops drawn before ordering.
  2. Samples and finishes approved Specification (CPS) requirement
    Material and colour samples and a trial panel approved in writing by the client and the architect.
  3. Renders, screeds and joinery installed Specification (CPS) requirement
    Cladding fixed and aligned, joints sealed, junctions with windows weathertight before scaffolding is removed.

Common non-conformities and follow-up

FindingAction
Cladding panels installed without a declared reaction-to-fire class.Stop installation, obtain the classification and have the fire compliance checked before continuing.
Water ingress at the junction between window and cladding.Inspect the sill and flashing details, correct the sealing and test with water before closing.
Colour or texture different from the approved sample.Compare with the trial panel; reject non-matching batches and record the decision.
Façade works started in a protected area without authorisation.Halt the works and regularise with the competent authority before resuming.

Frequently asked questions

Which façade products are under mandatory Moroccan standards?

Coated steel sheet (NM EN 10346), metal-faced sandwich panels (NM EN 14509) and glazed assemblies (NM ISO 9051). Curtain walls and façade paints follow homologated standards.

Does the fire regulation restrict cladding materials?

Yes. Decree No. 2-14-499 sets requirements by building class, and the reaction-to-fire class of cladding and insulation must be justified, usually through NM EN 13501-1.

Do I need permission to change a façade in a medina?

In listed sites and their surroundings, Law 22-80 subjects works to authorisation. Check with the urban agency and the heritage authorities before designing.

How does the façade affect the RTCM?

Walls and glazing make up most of the envelope; their insulation, glazing ratio and solar protection are part of the RTCM justification.

Why ask for a trial panel?

It fixes colour, texture and joint appearance before production, and serves as the reference when accepting the finished façade.
