Ventilated facades have become established as one of the most efficient, sustainable, and versatile construction systems in contemporary architecture. Their thermal performance, the protection they provide to the building envelope, and their wide range of aesthetic options make them a preferred solution for both new construction and renovations. However, understanding the construction details of ventilated facades It is essential to ensure a safe, durable installation that complies with industry technical standards.
At CELO Façades, we work daily on the design of fixings and substructures that ensure optimal system performance. In this article, we explain the most important details of a ventilated façade and how they influence its operation.
Why is it important to know the details of ventilated facades?
The details of ventilated facades They determine how the system will behave in response to:
- wind loads, impacts and suction,
- thermal expansion of the cladding,
- humidity and water ingress,
- support movements,
- safety requirements and European regulations.
Proper design of the substructure, the type of anchoring, and the fixing solutions are just as important as the cladding itself. A well-designed ventilated façade improves the building's durability, insulation, and energy efficiency, while also reducing problems such as detachment, warping, and leaks.
Essential components and details to consider in a ventilated facade
For a facade to function correctly, each element must be chosen and sized appropriately. Below we review the Key details on ventilated facades that are involved in its construction.
1. Supporting substructure: precision and alignment
The substructure is the skeleton that supports the cladding. It is typically made up of vertical or vertical and horizontal aluminum profiles, depending on the system chosen.
Key details:
- ETA approval and CE marking.
- Choice of alloys certified as EN AW-6005A T6.
- Checking lights between fixings and arrow values.
- Three-dimensional regulation to ensure flatness.
- Compatibility between the substructure and the type of cladding.
At CELO Façades we design systems that allow for precise regulation, facilitating quick assembly and perfect alignment even on irregular supports.
2. Mechanical and chemical bonding: coating safety
The type of fixing is one of the most important details in ventilated facades, as it ensures that the cladding remains fixed and stable under dynamic loads.
Critical aspects:
- Compatible with stone, ceramic, composite, HPL or any type of cladding.
- Combination of mechanical fixing + structural adhesive when required by the material.
- Selection of A2 or A4 stainless steel in corrosive environments.
CELO Façades anchors are designed to withstand high loads and ensure optimal performance throughout the building's lifespan.
3. Ventilated chamber: thickness and air circulation
The ventilated chamber is the heart of the system, as it generates the chimney effect that improves energy efficiency.
Important construction details:
- Recommended minimum thickness: 2–5 cm depending on regulations and material.
- Air inlets and outlets protected with insect screens.
- Camera continuity in encounters and corners.
A properly constructed camera reduces humidity, improves thermal performance, and prevents condensation.
4. Joints and expansions: controlled movement
The cladding and substructure materials expand with heat. Therefore, the joint details in ventilated facades are essential.
It should be considered:
- Constant horizontal and vertical joints.
- Specific separation according to type of material (stone, ceramic, ACP, HPL…).
- Well-resolved encounters in breastplates, windows and finishing touches.
A well-designed joint prevents breakage, deformation, and unwanted stress.
Construction details in ventilated facades: certifications and safety
A ventilated facade system must comply with:
- ETA (European Technical Assessment) approval. If required.
- CE Marked.
- Load, wind resistance and impact tests.
- Structural calculations according to current regulations.
At CELO Façades we offer technical advice and certified solutions that guarantee maximum safety and performance.
Conclusion
The details of ventilated facades They directly influence the energy efficiency, lifespan, and safety of the building. Proper selection of substructure, anchors, and fixings ensures a stable, safe system that is ready to last for decades without problems.
