Energy efficiency and thermal insulation

Global standards require that the building envelope, including ventilated facades, minimize heat loss or gain while optimizing energy consumption. These standards establish minimum thermal insulation requirements to ensure indoor comfort and reduce energy demand.

Health and moisture control

Ventilated facades contribute to healthier indoor environments by preventing moisture buildup. The natural ventilation within the air cavity between the cladding and insulation helps avoid moisture-related issues that could damage the structure and affect occupants’ health, complying with international health standards for buildings.

Fire Safety

Fire safety regulations for ventilated facades are stringent. Regulations require that materials used for both the cladding and anchors be fire-resistant. Additionally, a minimum separation between layers is mandated to limit fire spread, utilizing low-combustibility or fire-retardant materials. These regulations also dictate that components must withstand heat and fire for a specified duration to protect the building’s integrity.

Structural Safety

The structural integrity of ventilated facades is critical, as international standards define the load requirements the system must endure, including the weight of materials and environmental factors such as wind. Therefore, fastening and anchoring systems must be meticulously designed to ensure the facade’s stability and the building’s long-term safety. Regulations also require facades to withstand dynamic loads without deformation or structural failure. Additionally, designs should enable maintenance access, allowing for repairs or component replacements without compromising the system’s integrity.

Evaluation of material and system conformity

Globally, ventilated facade products and systems must adhere to standards that ensure their quality and safety. These products undergo rigorous testing to validate compliance with international standards, including fire resistance, wind resistance, structural stability, and durability. Products must also carry markings confirming they meet safety, health, and environmental protection requirements.

Parklex Prodema cladding meets these standards and is supported by international certifications such as the Avis Technique (France), ESR (USA), Zulassung (Germany), and BBA (UK). These certifications assess key aspects like fire resistance, thermal insulation, and durability, ensuring optimal performance.
