Long-term performance of thermal insulating composite systems based on water re...
Borsoi, Giovanni; Parracha, João L.; Bersch, Jéssica D.; Garcia, Ana; Dionísio, Amélia; Faria, Paulina; Veiga, Rosário; Flores-Colen, InêsExternal Thermal Insulation Composite Systems (ETICSs) are increasingly applied in both new construction and energy retrofitting, where long-term durability under environmental exposure is critical to preserving thermal efficiency. Moisture ingress represents a key degradation factor, reducing insulation performance and undermining energy savings promoted by the ETICS. The effectiveness of these systems is stro...
Diversity and distribution of microbial communities on the surface of External ...
Viegas, Cristina A.; Borsoi, Giovanni; Moreira, Leonilde M.; Parracha, João L.; Nunes, Lina; Malanho, Sofia; Veiga, Rosário; Flores-Colen, InêsExternal Thermal Insulation Composite Systems (ETICS) are frequently used to enhance the energy efficiency of the built environment. However, stains of presumable biological nature are often detected shortly after application, causing cladding defacement and altering the building aesthetics. To address which microbiota could contribute to these biodeterioration related color/aesthetic anomalies, samples collect...
Impact of Water-Repellent Products on the Moisture Transport Properties and Mou...
Roncon, Renata; Borsoi, Giovanni; Parracha, João Luís; Flores-Colen, Inês; Veiga, Rosário; Nunes, LinaExternal Thermal Insulation Composite Systems (ETICS) are constructive solutions widely used to increase the thermal insulation in new and retrofitted buildings. However, these systems can present several anomalies due to their constant exposure to weathering agents and anthropic factors. Water is generally the major cause of degradation. Thus, the application of water-repellent products can minimize the appear...
Performance parameters of ETICS : Correlating water resistance, bio-susceptibil...
Parracha, João Luís; Borsoi, Giovanni; Flores-Colen, Inês; Veiga, Rosário; Nunes, Lina; Dionísio, Amélia; Gomes, M. Glória; Faria, PaulinaThe use of External Thermal Insulation Composite Systems (ETICS) significantly increased in the last decades due to their enhanced thermal properties, low installation cost and ease of application, not only in new constructions but also for thermal retrofitting of building facades. These multilayer rendering systems are constantly exposed to weathering agents and anthropic factors which can lead to physical-mec...
Effects of hygrothermal, UV and SO₂ accelerated ageing on the durability of ETI...
Parracha, João Luís; Borsoi, Giovanni; Veiga, Rosário; Flores-Colen, Inês; Nunes, Lina; Garcia, Ana R.; Ilharco, Laura M.; Dionísio, AméliaExternal Thermal Insulation Composite Systems (ETICS) have been extensively used for either new constructions or building facades retrofitting in the last decades. These systems can provide improved thermal performance to the building envelope. However, their long-term durability remains a pervasive concern, with some systems presenting relevant anomalies after few years from their application. The durability a...

Borsoi, Giovanni; Parracha, João Luís; de Cooman, Quinten; Flores-Coles, Inês; Viegas, Cristina A.; Nunes, Lina; Moreira, Leonilde M.; Veiga, RosárioConservar e Reabilitar monumentos, edifícios e espaços são oportunidades únicas para fomentar a sustentabilidade dos territórios, constituindo-se o ENCORE 2020 - 4º Encontro de Conservação e Reabilitação de Edifícios numa ocasião ímpar para discutir os desafios da transformação no espaço construído: otimizar recursos, reutilizar materiais, melhorar a eficiência energética, repensar as centralidades urbanas, pro...
Evaluation of ETICS characteristics that affect surface mould development
Parracha, João Luís; Cortay, Armand; Borsoi, Giovanni; Veiga, Rosário; Nunes, LinaExternal Thermal Insulation Composite Systems (ETICS) are nowadays often used in new constructions but are also one of the most frequently used thermal retrofitting solutions for buildings. These systems have several advantages such as low installation cost, ease of application and increased thermal efficiency. Nevertheless, a number of questions have been raised on their long-time durability particularly relat...
Consolidation and chromatic reintegration of historical renders with lime-based...
Pascoal, Patrícia; Borsoi, Giovanni; Veiga, Rosário; Faria, Paulina; Santos Silva, AntónioHistorical renders are exposed to several degradation processes that can lead to a wide range of anomalies,such as scaling, detachments, and pulverization. Among the common anomalies, the loss of cohesion and of adhesion are usually identified as the most difficult to repair; these anomalies still need to be deeply studied to design compatible, durable, and sustainable conservation treatments. The restitution o...
Durability to marine environment of innovative products for consolidation and c...
Matos, Margarida; Borsoi, Giovanni; Veiga, Rosário; Faria, Paulina; Santos-Silva, António9th International Masonry Conference 2014, 7-9 July, Universidade do Minho, Guimarães; A common degradation phenomenon in historical renders is the cohesion loss of the binder:aggregate system, which is often linked to the presence of soluble salts. Cohesion is recovered through the application of consolidant products, being inorganics preferred due to their compatibility and durability. The aesthetic function ...
