Energy Efficiency and Thermal Insulation

Global standards require that the building envelope, including ventilated facades, minimize heat losses or gains and optimize energy consumption. These standards set minimum thermal insulation requirements to ensure indoor comfort and reduce energy demand.

Health and Moisture Control

Ventilated facades contribute to the healthiness of indoor spaces by preventing moisture accumulation. The natural ventilation in the air cavity between the cladding and insulation prevents moisture-related issues that could damage the structure and affect the occupants’ health, meeting international health standards for buildings.

Fire Safety

Fire safety is highly regulated in ventilated facades. Regulations mandate that materials used in both the cladding and anchors must be fire-resistant. Additionally, a minimum separation between layers is required to reduce fire spread, with low-combustibility or fire-retardant materials being used. These regulations also stipulate that components must withstand heat and fire for a specified time, protecting the building’s integrity.

Structural Safety

The structural resistance of ventilated facades is a key factor, as international standards set the load requirements the system must withstand, including the weight of materials and climatic conditions, such as wind. Therefore, fastening and anchoring systems must be carefully designed to ensure façade stability and long-term building safety. Regulations also require façades to resist dynamic loads without deformation or structural failure. Additionally, designs should facilitate maintenance access, allowing for repairs or component replacement without compromising the system’s integrity.

Evaluation of Material and System Conformity

Internationally, ventilated façade products and systems must comply with standards that ensure their quality and safety. These products undergo rigorous testing to validate their compliance with global standards, including fire resistance, wind resistance, structural stability, and durability. Products must also carry markings that confirm they meet safety, health, and environmental protection requirements.

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