Performance evaluation of pultruded fibre reinforced composite materials in ventilated façade components - Experimental testing and assessment methodology

The development of innovative building envelope solutions is crucial for enhancing energy efficiency and sustainability in the construction sector. Ventilated façade systems play a key role in buildings designed for human use, improving insulation and overall energy efficiency. However, they also present challenges related to heat loss, fire behaviour, water resistance, and long-term durability, which must be carefully addressed. This study presents the results of experimental testing on pultruded Fibre-Reinforced Composite materials applied in ventilated façade components, focusing on their mechanical, thermal, fire, and environmental performance. The research follows a structured methodology, starting with a review of existing literature, implementing and refining current testing protocols with a new approach, and calibrating simulation models based on laboratory analysis. The final phase involves new simulations to validate the study and ensure replicability. New criteria for the evaluation method are introduced to assess the overall efficiency of these systems under various boundary conditions. The testing protocol considers key performance indicators, including mechanical strength, thermal transmittance, durability, and weather resistance. The integration of substructure and cladding elements within the pultruded Fibre-Reinforced Composite-based façade system is emphasized, highlighting its impact on thermal bridging reduction and energy efficiency improvement. Additionally, the study also examines the fabrication process, recognizing its influence on the final product's properties. Guidelines are provided to enhance manufacturing standards and improve long-term reliability. Furthermore, an environmental impact assessment is conducted, addressing the material's recyclability and contribution to circular economy principles. The findings provide a comprehensive framework for designers and engineers to optimize façade performance while meeting stringent performance requirements.
